This was an exact replacement for the old one that lasted about 10 years. ua-cam.com/users/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it.

Pretty standard fix we do this all the time but with chillers when someone has oversized the equipment, it’s a less expensive fix then replacing the unit usually and usually trying to put a higher volume unit in could cause short cycling which reduces the units lifespan hence the holding tank.
@@kalijasin Tankless is great. This guy just needed a bigger unit or multiple normal sized ones to handle 7 GPM. Most Tankless heaters do 4 GPM just fine.
That poor guy got sold a bill of goods by his initial installer.

What do you think a standard boiler and a basic 80 gallon water heater would have originally cost vs. all of this? And I bet all those uninsulated pipes circulating the hot water between the small and large tanks means it is less energy efficient too. It sounds like a great idea, one boiler for both hot water and heat, but only if the system is properly sized for the expected demand.
@@peppeddu My point was that he shouldn't have bought the dual use in the first place, because a basic hot water heater and basic boiler for the radiators would have been wildly cheaper, less complicated and more efficient. I get that this is probably the most cost-effective way to fix the current issue. But it is a problem that should never have happened in the first place.
That is kind of the only solution. I had the same issue. I purchased my house with a large soaker tub and the house came with (2) 40 gallon traditional water heaters. That worked fine until they started leaking. I replaced them with a the largest tankless unit that I could find. (I believe that they are limited to 199,000 btu's due to some code constraints.) Well, the tankless worked great for the rest of the house, but it couldn't keep up with filling the tub. I live in northern Illinois, and the incoming water from the ground was around 50 -55F. The tankless can only raise that water 40 degrees at 9 gallons a minute, so in order to get a good 50-60 degree rise, the unit throttles down the flow. So it literally would take over a half hour to fill the tub. I ended up purchasing a 75 gallon traditional water heater to preheat the water, and then the tankless picks up the slack. I have to believe that there is a better solution to this problem; but I have yet to hear about it.
Depending on what brand tankless you have, you can connect multiple in parallel, they have cables that let the units talk to each other so that they can share the load evenly. Most brands let you connect up to 4 units.
Tankless is way overrated, an 80 gallon heat pump hybrid water heater is probably the best option on the market right now. 80 gallon capacity is practically unlimited hot water (unless you have like 5 people showering at the same time) and the heat pump gives you fractional operating cost over a traditional electric. Upfront cost is the biggest downside.
Maybe, maybe not. There are different advantages and disadvantages of tank, tankless, and hybrid units that depend on one's unique situation. In this persons case, a different choice when the hybrid unit was first install would have been better for them but. as it is, this add-on reserve tank resolves the issue at a lower cost then replacing the hybrid unit itself. Their new setup Isn't really as complicated as it looks on the surface.
Very good explanation of the problem! How does the cold-hot mixing work when leaving the extra big storage tank? If mixing in cold, then less hot water is needed; therefore, I think the storage tank is much too large and wasting too much energy.
The original one was not sized according to the demands of the house. He has a huge bathtub. That's why they added the storage tank. And an expansion tank isn't to hold hot water, it's to prevent excessive pressure buildup due to the thermal expansion of water heating up.
They needed a 8gpm tankless they got the wrong one. It’s sad because they have this one hooked up to gas too! I’d opt for a new tankless properly sized.
Yeah they rate tankless heaters by their rise and their output per minute. If you get a bigger system with a higher rise and more output he wouldn't need all that.
Would've been simpler to switch out the heater for one with a high enough BTU to keep up with the flow rate of the tub. Water is flowing too fast for the old one to work correctly.
Not really, They only need the higher flow of water for the tub only as everything else including showers work fine with the old unit. I imagine the coast is lower for a simple water storage tank, temp sensor, and pump unit then a whole new hybrid tankless water heater unit.
I said, "simpler". They might be saving some money, but adding a lot more fail points. And I did some Googling; the price of a fully tankless heater that could keep up with his needs is only slightly more.
@@jamiemacdonald436 ... ok, but he really didn't need the full 80 gallons because you can use a 40 gallon tank, then heat to 140 degrees and use a mixing valve to get 60 gallons to the tub at 104 degrees. (fairly hot bath) There are indirect fired tanks out there for $1500 - $2500 plus installation, which will recover faster than a gas water heater. Heck, I'm still using my 27 year old Amtrol Boilermate unit to fill my hot tub and that will use however many BTUs my boiler will crank out. (up to 190,000 BTUs) They still make a similar unit with a poly tank and the warranty is longer!
I love how it just so happens to be Jim Papalia there to do the install. For those who don’t know, that company is huge in the greater Boston area. It’s not some dude. But he happened to be the guy 😂
OMG that unit is a beast and can't keep up with 7.3 GPM?? I have one that is this little tiny unit that keeps up with my 15 GPM that i have for my 80 gallon Jacuzzi Watched to the end.. its not tankless is why and its a combo unit
This is the exact same thing I had in the 90s with my oil fired boiler ... it was called indirect hot water... apparently now if you buy an expensive on demand hot water heater it's now a reserve tank ... ok?!?!
Yes but one is much smaller and has a heater attached while the other simply stores extra heated water for the tub from the first. Having more than one hot water tank isn't that unusual in some very large house. This was likely the cheapest way to resolve the problem.
Hold on a minute. A "tankless" was installed, but turns out it is a tank system with 20g onboard? What in the world, where is the efficiency. The unit is massive, I have seen smaller 7g/minute systems installed on gas-only connection. Second of all, what is the point of the massive "tank/tankless" when you're throwing a 80G stainless in there???? That thing is probably $2-5K and all of the pro-press fittings and copper are another $400-500. This job was probably quoted at $6-7K and Henry just wanted a hot tub?? Why, just why. I have a 1998 50G old-fashioned water heater that hasn't been drained or services besides a rod cleaning. I get hot showers, dishes and baths whenever. Unreal.
I have a tankless heater that cost me $180 and I get 140° hot water all throughout my house in under 30 seconds. I don’t know what heaters y’all are buying but you’re doing it wrong. This man went from a tankless to a combination to now having a tankless and a tank water heater. It’s backwards.
Why can't he simply reduce the output of the tub filler to 2.5GPM once the first 20 gallons is put into the tub? Is there not a volume control on the tub filler? Sure, it'll take a few more minutes to fill the tub, but then he could avoid the cost of the added equipment, as well as the added energy costs to keep the indirect tank constantly heated.
@@dancooper6002 I doubt the water would cool down that much in the 10 extra minutes it would take the fill the tub at a slower rate but hotter temperature.

Huh… so they heat water ($$) and then mix it (downstairs… on the ‘hot water line, mind you)… and send it to all the water appliances. Pay to make hot water then cool it. Well, that certainly makes sense. Not.
The reality solution. Turn the flow down on the bath tub so the boiler can produce on demand what is needed, Tell the women to have a shower.Reality is the you spend $$$$ to heat the water up and all they do is sit in there for 5 mins.
If you paid attention to the video, the first thing he tried was filling the tub with the hand wand at 2.5 GPM. It took so long that the water cooled off already!
@@rupe53 That was through the shower head that was restricted. If you open the tap slower than full blast then you can combine the instant heating and the tank. Also the shower head flow will lose more heat to the air than the tap flow. There is no rocket science in this, it's obvious stuff.
@@logik100.0 ... the problem with a boiler like this is it's only rated for around 3 GPM to get the temp rise for domestic water. That's why they have the internal tank. It's just enough for front loaded washers or a 10 minute shower.
