      ​@@Martin_HermannYour fridge is a heat pump. If you feel the air coming out of the vent (usually bottom front) it is warm air. That air was heated by pumping heat out of your fridge (via coils and a compressor). Pumping heat out of the fridge keeps it cold.
      Residential geothermal is the same idea, but the inside of the fridge is replaced by the ground.

Vertical boring is what you do in a city...it is possible in most areas. 150ft/ton straight down. We bore 5" holes drop the pipe, grout with bentonite/graphite mix. Also we use methanol as an antifreeze and have protection to 15°F. Not possible on every city job. But many more than most people think.

    Important to note that when using distilled water or reverse osmosis water (RO), you have to be careful about what fittings and piping are used and where. Polypropylene, Polyethylene and 316L SS are preferred for high purity waters. You can use PVC and CPVC, but they are more prone to failure long term. This particularly true when using glycols for freeze protection.

      @brnmcc01 2 роки тому +4

      @@Challenged1 No, bad points. Very pure water has a resistance of something like 18.2 Meg ohms. In order for corrosion to occur, there needs to be an anode and a cathode, and some impurities in the water for the ion exchange to occur. For example, try electrolysis on some lab grade ultra pure distilled water at a low voltage. It won't work because the water is a very good insulator. Add a little baking soda to it however, and suddenly you'll get good production of Brown's gas (2:1 hydrogen to oxygen ratio).

    Hey quick comment. In my experience, I've used 50/50 for non automotive use. As an automotive professional, I know that antifreeze/coolant also has lubricants, anti corrosion, anti organic life, on top of other additives. Diluting antifreeze may cause premature impeller and bearing wear, loss of anticorrosive properties, and affect the PH level allowing organic life to grow. Mind you this takes a really long time.
    Even though you may not need "antifreeze", I do recommend something like freezetone that offers such additives to continue protecting your system with superior conductive properties.

They used two deep rock wells. One to pull the water out of, and service the water needs of our property, and the other well to dump the water back into. The problem we had was the pump drawing the water out of the main well, was always breaking down, and had to be serviced several times a year.

    They can go deep with a closed loop system, if you have limited space. Instead of drilling two wells for an open loop, you drill one hole and place the heat sink loop in the hole. It may not be as efficient as placing that loop at one specific depth, but it's still way more efficient than air to air heat exchanges.

    A little over a decade ago, while living in PA, I had to replace our furnace and AC. I chose to go geothermal. The installer put in a vertical closed loop system with two wells to take advantage of the heat transfer properties of the water. My old furnace was propane fired and was really expensive to operate (over $600/mo in the cold season). After all the tax credits, the geothermal system ended up being $8500 more than a high end hybrid propane/heat pump system. This included installation of an 80 gallon hot water heater and 55 gallon buffer tank. I had estimated a return on investment of just over 3 years. It ends up, the gt heat pump was so efficient, I got my money back in just over 2 years. Winter heating costs dropped to less than $55/mo. Summer cooling dropped by more than $100, and I also got free hot water in the summer due to the buffer tank. And, because the system ran more frequently than my old one, it was way more comfortable. I really miss that system.

    I installed a Fujitsu 12RL mini split heat . pump several years ago and am totally glad I did. 1 unit, centrally located in my 1900 sq ft ranch. I live in Maine and have wood as a back up. The unit produced useful heat at -15 F one winter - it is only rated to -10F by the manufacturer, I was told that is as cold as the testing equipment got. I usually burned 6-7 cords of wood a year, the installer said I would only need1/2 cord a year to supplement the few extreme cold days. I could hardly believe him but he was right on the money. I burned 1/2 cord a year for several years, and last year burned no wood at all. Essentially, a good heat pump is roughly cheaper than any heat source but wood, and about the same as wood but without the labor and mess of wood, which is considerable. I got the heat pump because I was getting older and the wood was not getting easier. I am totally happy with the result. The coldest part of the year I would burn 1 cord a month, at $200/cord. The heat pump costs, during the coldest months, about $150/month extra on my power bill. Yes, in my case it has been cheaper than wood since with wood I heated my basement also, and liked to keep the woodstove cranked right up to keep the chimney clean and heat both floors.With the heatpump, the basement is cool but not too cool.
    In the summer, the heat pump is way more efficient than my air conditioner was. During the hottest part of the year, the AC added $80/month to my power bill. The heat pump is much better at cooling than the AC was, and much cheaper to operate as an AC too. A mini split has no inefficient ductwork to heat or cool, and loses no electricity pumping through ducts (my understanding is ductwork can sap up to 10% additional electricity). There is a dehumidifier setting that costs about $15/ month to use continuously in the hot part of the year, and I find that when used, which is all the time in the summer in my case, the AC setting rarely is needed. When the AC setting is used, there is not much impact on my power bill, so it is clearly getting a much greater cooling bang for the buck than my old AC did.
    I'm totally happy with my switch to a cold climate heat pump. It paid for itself in 3 years when compared to my old oil furnace, so it will be well worth it even planning on replacing it every 12-15 years or so. The woodstove is excellent backup for power outages, which can be quite long where I live, in fact there was a three day outage this past month, and as a supplement for extended extreme cold, which has not been happening in recent years.
    The correct heat pump is the obvious best choice for most homes now, imo. Electricity costs are much stable than heating oil in the long term. You can make your own electricity too, with solar panels. A grid tied solar power system with a mini split or geothermal heat pump is the sweetest arrangement of all, also imo.

    Used 300’ per ton as length of tubing. So ended up with 2 loops 6-8’ deep one goes out with pipe in bottom of trench leak tested and back filled with 2’ over that pipe, top pipe is 6’ deep for a total for 2.5 ton is 1000’
    3 ton unit has 1 continuous loop of 1000’ 8-10th deep.
    System was designed without additional electric heat for a backup. In 21 years have not needed it either, even at 10pm outside.
    Very happy with this system. Did not use anything but water with make up valve and expansion tank, no glycol at all.
    Pipes are in the attic which I run 2 pumps in winter 24/7 to prevent them from freezing, summer they run with compressors.
    Did all the work myself except for the digging, hired that for $1,000.00, and I tested for leaks and back filled myself.

    Great video very informative. That being said I work for a company that treats these types of systems and there are a few things to keep in mind. Yes water is better at transferring heat but if you go below 18% glycol you will have sever bacterial growth in the system. This can rob it of efficiency while also causing maintenance issues. I wouldn't go below 30% with a glycol mix. Also if you are using a gycol mix it is extremely important that the water you mix it with is pure water whether that be distilled, DI or RO because regular water will form precipitates that can reek havoc on the system like the bacteria. I like the comment below me on using methanol although going with just water and keeping it moving would work too.

    You can do something very similar on a boat in some areas. The water around the boat is typically cooler than the air in summer and warmer than the air in winter. If you can utilize this difference you are that much more efficient. Marine heat pumps have been around for years and my particular favorite is the MarineAir 16,000 btu 120 volt model. There are things you must do however. There must be an hull strainer and an in line raw water strainer before the water pump. The strainer and pump must be below the water level that’s outside of the hull. There must be a flow switch (not provided) to shut things down if there’s an obstruction. Loss of flow can be more catastrophic in winter because slow flowing water can freeze the water in the heat exchanger, rupture and flood the hull. Moisture alarms throughout a boat is always a good idea. A condensate pump to move water overboard is also required. It’s also preferable to have the heat pump unit above water level so when it cycles off some water runs backwards through the impeller pump and the two strainers help with backwashing and keeping things clear.

    I had my horizontal bored 4Ton system installed for $15k before tax incentives. The heatpump was a used unit purchased locally from a private seller upgrading to a larger unit with only 5 years of use on it. They were upgrading as they added an addition and needed more tonnage and a larger unit made more sense rather than a secondary. The horizontal bores were installed with 5 lines of 250 foot in length making a round trip loop of 500ft per loop. A manifold was buried outside by basement so a smallish excavation was needed for that. The manifold is thermally welded to the pipes preventing any possibility of corrosion to clamps. The loops are 1 inch in size and the output of the manifold is 2 inches all of the lines are high density PEX. Part of the install I was in-charge of getting the necessary electric to the unit (not insignificant as there is an emergency aux resistive heater that can carry the needs of the home if there is a catastrophic failure of the heatpump.) The unit was transported from the old home to mine by me but removed from service, validated, and installed in my home by the same company. The antifreeze is a 15% solution of methanol. The lines were pressure tested before attaching to the unit for 24 hours. The unit is rated for 6.1 COP at 68 degrees and 18.8 EER at 86degrees. (full loads reduce those efficiencies a bit). Another point to add is the de-super-heater. This permits me to offset my water heating costs by dumping heat into a potable water buffer tank that pre-heats my well water allowing my main water heaters to work less hard.
    I could have higher efficiencies with a variable system rather than a 2 stage and a variable pump rather than a fixed but it made more financial sense to buy a well cared for, inspected, used unit with proper service records than it was for me to purchase a new unit with these more advanced features. At some point I might upgrade the unit but even then the costs will be far less as the lines will never need replaced and have a 100 year warranty. The expected life time from a unit like this is in the decades so a unit with only 5 years is just getting started.
    When I was evaluating this I too was in a predicament with the cost to install natural gas at $80k and propane costing around $1500 for half a year. I upgraded my whole house and removed the old propane fixtures installing an induction stove, a heat-pump water heater, and an on-demand electric water heater. I also had solar panels installed that cover all of my electrical needs for over half the year. I also have an electric car and electric mower so those numbers could be higher for a person who drives a gasoline car. As a point of reference I have a builders grade home built in 1985 in NE-OHIO (Zone 5) that is 2016 square foot.

      Another point of geothermal is the benefit of no exterior noise, there is no external air handler that is making noise. One negative is the speed of heating is slower on a geo-thermal system as it outputs less BTU per unit of time vs a fossil fuels system. This means if you normally turn your heat way down when leaving the home the time it takes to re-condition the space will take longer. (honestly I don't notice this much and when I leave my home the heat drops to 55 and the AC goes up to 88). A positive is that there is no inherent need for air changes like a traditional fossil fuels system (like I had) that drew air for combustion from the home and exhausted it out the roof. This means it allows the home to leak less air during heating seasons as less air is drawn in though cracks to replenish the air lost though the flu. Air moves slower also on a geothermal unit meaning the ducts are quieter and less dust is spread around. There is also no risk for CO poisonings as there is no combustion occurring. This lowers my home insurance costs as there is less risk of fire. A ground source AC geothermal unit is also more efficient than and older central air - air sourced cooling unit. As said in the video the efficiencies don't vary due to the weather as the ground temperature remains constant. (loads will vary and that can effect efficiencies (what stage is running or the set temp inside the home).
      I was also able to sell my old central air unit and furnace for 1k offsetting that out of pocket costs. So after tax incentives and the selling of the old furnace unit my costs were only $9.5k. For that cost I have a system far more efficient, that adds value to my home, improves the air quality, and can be powered by solar. If I ignore the electrical loads and only consider the propane saved with this geothermal unit, I have a payback period of about 4 years. Obviously this ignores the increase in electrical usage from other propane conversion (offset by solar), the reduction of electrical usage in the cooling seasons, the reduction of home insurance, the improved efficiencies of the home system and air tightness, the improved health with less dust and CO/CO2 production, the noise reduction or longevity of a geothermal system vs any other system being exposed to the elements outside or dealing with flames.

I also was told vertical wells are a bit more efficient but come at a higher cost due to the need for a well to be dug. As far as landscape goes except for the disturbed land next to my basement wall where the manifold was installed you would never know that there was any system present. This is nice if you are in a rougher neighborhood as theft of AC units happen in some neighborhoods.

    Thanks for that Video
    I can add some points that you didn't mention.
    1) you forgot to mention that not only the cold side of the heat pump makes a difference in cop but also the hot side. At first I would optimize at the inside. You showed pictures of ducts inside the house. I assume your heat pump creates warm air that is going to be distributed across your building. As you mentioned water is more eglibe for transfering heat, i would suggest to use that instead of air. normally at my home country you would run coils in the floor of your building, warming that. That way the heat pump only has to heat up the water to 95°F in winter time to keep your home warm. The pump that delivers the heat to the whole building eats up only about 10 - 30 Watts, what is sure less than a fan needs. Additionally in the rooms you won't have noise and air movement.
    1b) We here also do some ducts but we run them only to exchange the used air against fresh air from outside so you need to open the windows less for air quality. This air is brought inside the building by a heat recovery exchanger to lessen the heat loss.
    2) to decide if a ground heat source or outside air source is better it is important to knwo where you're at, how many hours per year it is going to be how cold. If you know that you can do the math and then decide the annual more - or less energy you need for either system
    3) you also want to have your ground analysed to know if it is better or worse suitable for the geothermal system you describe before making descisions
    4) There is no xxx feet of pipe is needed per ton. this is absolutely dependent on the kind of ground and the operating hours per year, and if you plan to use antifreeze in the system. There are people around who have software to simulate this.
    5) Antifreeze: Normally you want to use 0% or 20 - 33% of antifreeze, if you use glycol. the glycol we get here contains anticorrosive elements. Therefore you better inform yourself and fill in the mixture that is mandated by the manufacturer. If you design your coil for usage with plain water and get into trouble you can always later change to antifreeze filling. Be aware that you will never design your coil to be sub zero celsius (freezing point of water), or you'll suffer of performance of your ground coil, or even destroy it as time goes by if you repeatingly freeze the ground around it.
    6) If you need to cool the house in summer you can use the water of about soil temperature and send it to your pipes in the floor. that way you don't need any energy (apart from the two pumps) to cool down your house. If you are at a warmer region and that is not enough you can reverse your heat pump or have a air handler that is connected to the outside coil
    7) if your garden is to small then use vertical drilled holes. they need to be quite long and this is nothing for DIY, as it requires special skills. the length and the amount of those borings need to be simulated, to ensure that you will be able to use them for the desired life span. in several hundred feet depth the heat is not really easy moved and if your vertical collector is to small you risk of cooling it down to an unusable temperature in 5 or 10 years.
    by the way: if you connect your AC to it and heat your heat source up in summer time it helps a lot, so you need smaller borings and get an almost infinite life span out of it.
    8) water quality: I'm pleased somebody speaks about the water that is going to be filled in a circuit. yes, you can use destilled water, that's great. At my place we have special water softener resin cartridge that take out all of the salt (not to mistake for ion exchanger resin that can be regenerated with salt), what gives almost the same quality of water as destilled water. Advantage: you don't have to carry the water around but have a small cartridge you connect to your tap water. Cheaper? maybe not, depends.
    9) about the layout of your trench: it is not always best to dig as low as possibe. The design of your collector needs to make as much as possible use of the ground between the collectors. If you speak a little bit of german or know how to use the translator then you can find tons of useful informations and another angle of sight how we're doing such things in europe. Assumed you understand metric units maybe you will find it interesting to read on some forums and company websites. try following words in google: grabenkollektor, ringgrabenkollektor, trenchplanner.

Poor insulation means your system works harder then it needs too, thereby reducing efficiency.

I installed a 6000 foot loop bed 3 foot wide and 10 foot down, 6 1000 foot continuous runs, my 2 units can simultaneously use off of the bed, i got 30% from gov, 1500 from my co-op, 1200 from my geothermal unit manufacturer and 800 from my indiana state, i also have the prewarmer coil for my waterheater and a humidifier and air unit to help with any bacteria and virues.

      What stops the ground from adjusting to the temperatures in the house?
      As I understand it, you use the ground precisely because the temp of the deep ground is pretty constant. This is because the ground doesn't move heat around very well (if it did, it would be the same temp as the surface). So once you have either sucked all the heat out of the soil surrounding your pipes or dumped heat from your house into that soil, how long does it take for that soil to recover back to the normal temp?

They do not make a lot of noise, I might say twice as much as a refrigerator. Some are noisy, others are not so much. Many times the airflow noise is greater than the compressor noise, but it can vibrate, so basically not wanted in your bedroom closet, but if in the basement it is fine, as you will not hear it in the next room, more than a dishwasher.

    As a point of reference, a book I own about Earth Covered Houses, stated that the minimum amount of earth coverage required to decouple a house from the surrounding air was one metre (or yard), so going down to two or three metres would be more than enough earth coverage for the piping system. The only other thing to consider is that the deeper that you dig your trench the wider it needs to be battered back to prevent collapse during installation.

    Wondering how long it will take to amortize the cost of the system vs the savings you get. For example, at my house which in only about 1000sq/ft of living space on 100 x 50 ft land, a geothermal system would have cost about 28K (turnkey) however they would have had to dig an 8" diameter hole/well to about 400ft deep for the piping(because of the lack of land to install a horizontal system). Because of cost, my bride was totally against the installation of the system however, it would have been about 11 years to recoup the investment which means, this year, it would have finally paid for itself and this in not taking into account the forever rising cost of electricity and natural gas. BTW, thanks for your many clear explanations of various systems and for the interesting talk.

    The reason for not digging too deep, is that you want the mass of dirt around the pipes to warm up during summer. You have to remember that the term "geothermal" is missleading. You use solar energy. The sun has to heat the ground during summer, then you extract the energy from the ground during winter. If you dig too deep, you risk to permanently cool the ground.
    My system, used since 2002, has the water pipe's 4 ft down into a field. Pipe is 1-1\2" plastic water pipe, about 1200 ft. It works perfectly, the incoming water/alcohol gets warmer as soon as the snow melts off in the spring.

      You seem to be talking about a system for heating only. I'll bet you live fairly far north where air conditioning is not commonly needed. If you both heat in the winter and cool in the summer (for approximately equal periods,) you will not permanently cool the ground and the influence of the sun is unimportant. In the system described in the video, "geothermal" is not at all misleading.
      Our small house's geothermal system uses a single borehole that goes a hundred meters deep or more. During the winter, we suck heat out of the ground around the well; during the summer we push heat back down there. We live in Oklahoma, where the heating and cooling needs are almost perfectly balanced.
      The earth's heat comes from the core and mantle and any heat variances that may be created in the crust near the surface even out over time (I wonder how rapidly). The system in the video has worked well for the vast majority of U.S. residents -- from Ohio in the north to Texas in the south. I'd be interested in learning about research into any changes of efficiency over time that can be shown to be because of overheating or overcooling of the subsurface matrix near the piping. Also research into how rapidly heat conducts through rock, etc.

I learned so much from you (admit I had to replay it a few times, just a simple 64 yr old blue collar gal). I'd have to do the 2-well system. I moved to Iowa, into an old house on a small .03ac lot. Apparently this county has the hardest water in the state of Iowa, at 297. In researching this hard water issue, I discovered a company that has this small gadget that brackets around the water line, that not only renders the minerals to harmless states and prevents buildup, it begins eroding existing buildup! AND it implodes bacteria. (No I'm not affiliated.) I am excited at using it now as I can remove the harmful salt/sodium water softener. And I could use it on the 2-well system you described and not worry about the buildup! Its affordable, too. IF I could only afford the rest of the geothermal... lol.

    Do note that you want to put in enough heat in the ground in the summer as you can cool down your well area. You may not notice it as it wont be apparent in one or two years, and you may suspect your pump is loosing efficiency gradually. I know a larger complex where this was an issue. The system was fine in the beggining and got more expensive than the natural gas it was replacing. Turns out the buildings were comfy without ac during the summer so they seldom used the cooling function. The issue was solved by charging the system with summer heat, without a heat pump and the heating bill was fine after that.

      @@maranatha3333 Yes because basically, the heat you put in or take out of the soil spreads out. It needs balancing out to some degree. For instance, if you do not cool your house off in summer you are not pumping any heat into the ground. However, in winter, you are extracting heat from the ground. Meaning you are making the ground very cold. Well, that ground will stay cold for a very long time. Possibly a number of years. Ground temps around here are about 54-57 degrees Fahrenheit. If you live in an area that gets really cold and the top 24 inches of the soil freezes then you know how long it can take to thaw that out. Imagine it 7 to 9 feet down where every winter you have dropped the temperature 10 degrees. The colder it gets the less efficient it is for heating the house in winter. It would make it super efficient for cooling in summer though. This is why it needs balanced out a bit and should be used in both seasons.

    Great info. Have almost 5 acres, but I also live in New England so rocks are our major problem. I’m guessing the two well system would work better, but the plus side is the water table is only about 8 feet down. The downside is our water is hard as well, but mostly iron.

    I have seen several geothermal systems installed in suburban settings in our town. The yards are big enough for vertical wells, but not for going horizontal. Each of the systems I am familiar with used one or two wells with a closed loop. I believe the wells are 450 feet or so deep. You do not necessarily need a lot of land to use the closed loop.

      Sand is porous. That means it is not good for closed loop as the gaps act as insulators.
      It also means that the open loop systems naturally work better than in other dirt. So you were wise or lucky to chose open loop

    Great video. I only have one small correction. Closed loop is generally more efficient than open loop if done correctly when you look at total system energy. Open loop typically uses a 1/2 hp well pump vs closed loop using 1/8 hp recirculating pump. This more than negates any small temp rise losses vs an open loop system.
