By the way thank you for being direct and Elementary at first just in case someone has not been exposed to a concept... you would be surprised but this is the fifth video that I looked at just explaining the basics of how a boiler Works in a house. You rock!
Please keep it coming. I learn about boilers with you in a nice relax way, and I like that. Thank you. I am your Fan!!!!
Great video, much more clear explanation than most other boiler related videos.
I am a new home owner and our house has a boiler with Hydronic Baseboard heaters. This video gave me a great overview. I am usually only use to furnaces.
Best video on the topic ive seen so far
Great video with a proper amount of information!
Nice soldering bro
An excellent video, right to the point!
Thank you!
Great video. I have the Super Hot system just like your video and recently I am trying to add a Nest Thermostate which requires me to install the Nest Power Connector. However, I am having trouble to figure out where to connect the c-wire to the zone control board as it seems to have different wiring label. Appreciate if you can help.
Good video. Thanks. Possible on sequence of operation to show voltages ?
Really excellent video! Thank you!!! This helped me troubleshoot what I think is a bad flow control valve. The heat is stuck on even when thermostat is off with batteries out and no short in those wires. That flow control valve’s end switch is outputing 26 VAC on both wires (not neutral or thermostat W / heat wires) even though the thermostat signal is 0 / not calling for heat. Never knew or seen a heating system with a failure that kept it stuck on. Usually it’s off because bad thermostat batteries, open circuit, or a failed component.
If it’s stuck on, I first check for shorted thermostat wires in the wall behind the thermostat or elsewhere because if you strip the wires back too much/far, when you push the thermostat to the wall and secure it in place, those wires can be touching the exposed copper and shorting which calls for heat even if the thermostat internal switch is open / not calling for heat.
Thank you for the helpful video. I’m wondering how to check fuse ? My mini gas machines is not working properly as usual... thank you
Really Good video!! My Superhot boiler has an err 65 code and we have no heat. Having trouble finding information online about this code and how to fix it. Any suggestions or feedback would be appreciated.
I start my commercial plumbing and pipe fitting 4 year apprenticeship this week and this was a great video
Thanks, keep on rockin!
Awesome! Good luck on your journey!
@@PROSDIYitss make a diference like heating water heater system... istead to use a boiler?
Thanks for the video. My super hot mini gas has a 4 zone card but I see the contractor hooked up all 3 zones to only 1 zone on the card. Im thinking I will run individual wires to the Stats, zone valves and End stop Switches. That way I can see the zone lights on the card come on. He also used one of the zones 24V to feed a flow valve that comes off the water tank. I assume that is OK.?
Over time both outputs on the card that feed the 120V circulating pumps are blown so instead of buying a $400 card I have the pumps hard wired 24/7. Im not very good at soldering but I ordered a $16 output relay to try to repair the card and if that works I am going to get a relay the card will feed which will take the stress off the card outputs. Im not a furnace guy and Id love to know if Im on the right track before I start snipping wires. Thanks for any input.
Great video it is a lot of things I've never seen
I bought a house that has hydronic baseboard heating with a Weil McLain boiler. Unfortunately, the boiler was not used for five years. What is likely to fail in such a system during that time? I'm planning on repairing the plumbing, which has burst at certain points. After that, I'm looking for a professional to turn the boiler on. How do I synchronize my work with the specialist? I am first checking if there are no leaks in the circuit that heats the water for kitchen/bathroom faucets and showers. So far so good.
I am looking at a MG-150 MBH boiler and it is currently running natural gas but I want to convert it to propane. Will this be efficient and it is for floor heat already installed? Natural gas is not available to me as I live in a quite rural property.
what should the limit switches be set at ? Thx , Arthur..
Great video.
Great video
Just came across your video. Very good explanation... Thank you.
Would it be possible to show us how to do the annual flush of system? Some say it's recommended.
And also, can I turn off the pilot in the summer and re-ignite it in the fall? Burning pilot fire all summer seems a bit of waste...
Thanks again.😊
That’s a pretty fancy boiler.
How do you raise the temprature of a new super hot boiler?
GOOD JOB
Do you have a video for service on a mini gas? Adding inhibitor etc?
I appreciate your video is for "in-floor heating" however, are "in-room hydronic radiators" still a popular choice? How many new "radiator" systems do you estimate are installed each year in the US please?
hi from Canada, it was very informative video, i have the similar old boiler made by Allied model SSG225-N , the issue with it is that its standing pilot sometimes just turn off, so ive replaced the thermo coupler. its better now but still it turn off some times, so i have to re light it again. someone told me its very old just replaced it. and i took some estmates as well but they are askind 20k . which is insane. is there any way to fis this issue. is it a gas valve or what is it to fix this issue? please need your advice and help. thank u
Hi, Does the flame sensor only sense the pilot flame? or it will tell if the main flame can stay on for all the time?
This is an awesome video. I vacuum around my boiler and wipe off any surrounding dust on a regular basis to keep it tidy. Do the burners and heat exvhanger need regular cleaning on this type of boiler? Thanks! Liked and Subscribed!
Thank you so much for this information Im studying for the read seal and have to write it Monday.
Good luck!
Did you pass?
@@kaelanross185 Wow I'm shocked you took the time to check in on me. This means allot. No sadly I didn't pass. But I'll try again. Third times the charm rite?
@@markeldamgaard No problem. I'm actually a second year plumbing apprentice myself from BC. Good luck on the test and I hope you pass!
@@kaelanross185 No freaking way. You live in B.C. as well? What town?
I have a boiler identical to the one in here; it can only handle 4 zones. How can I connect this boiler to an external zone valve control, in particular tekmar 306v?
awesome video
Using this brand
an older model chocolate brown trimming
Problem: lower floor gets good heat but on the second floor of house, two rooms don't get any heat.
How to can we fix this? Thanks
Does hydraulic heating the same as this boiler system (according to the title of your video)? I saw an article talks about one of the benefits of hydraulic heating systems is that " Forced air systems can draw moisture out of the air while heating it; hydraulic heating systems don’t dry out your home like other radiant heating systems since they use a liquid in a closed system to heat your home." is that correct? because I saw the other "guru" talks about the benefit of the forced air system is that "forced air system has the benefit of speedy heated, area control and has to humidify/dehumidify implication." What is the better system when encountering a dry and heated indoor air situation?
Why is the air scoop between the return and supply?
And what is the purpose of that crossover where the air scoop is?
I would like to ask how to remove a zone from a system. Mine is Saturn series super hot boiler with 3 zones.
Hi, I have the same boiler. It shuts off randomly turning off both pilot flame and main burner. Any suggestions on the cause?
Hi , its about Mini Gas Super Hot boiler . Recently I replaced the thermo couple because the pilot kept going off frequently. But after replacing the thermo couple the pilot light kept going off within one minute after main burner starts firing ; if the main burner does not cut in pilot burner runs continuously. However the problem resolved once I closed the round hole beside the pilot burner ( for inserting the ignitor to the pilot burner) by moving the sliding plate. Now the boiler is running continuously but the flame is yellow ; I guess the air flow has been reduced by closing the sliding door beside the pilot burner. Please advise whether is it ok to close the sliding door ? what to do about the yellow main flame ?Amman Zaman
Our Saturn MG series super hot boiler stopped heating yesterday and reads error code 63. Not sure what to do next.
Do all boilers circulate an antifreeze coolant water mixture? If true then the hot water storage tank contain that same mixture correct? Great video. Thanks!
It is optional to run a glycol/water mixture. On my personal home I only run straight water as I have 2 heat sources in the case one goes out. The benefit of glycol/water mix is that if the system fails then the system won't freeze up. The benefit of straight water or treated water is it is slightly more efficient. You're correct, if I was to use a glycol/water mix I would mix it at the feed/storage tank. Thanks for the questions! Cheers!
Next Time I would like you to show me the proper way to maintain a gas and steam boiler ( residential ). There is a
several guys doing it. I would like to see your method. Thanks
Our boiler isn't starting. House temp is down to 65 and all 4 zones are set to 70 . Still no boiler firing ( pilot is on ). The water temperature of all supply lines are cold.
I found that if I turn OFF the power switch to the boiler system at the boiler I hear zone valve operating then all is quiet. I wait for maybe 30 to 60 seconds and switch ON the power and I see flu valve opens and the boiler lights off the system builds up heat and circulation. It seems to work normally until it satisfies the zone Temp and shuts down. Some how killing the power switch seems to reset the system and starts the boiler burner. Something is not sending the message to the boiler start control.
But yet it gets the message when I switch OFF the power monetarily and then back ON
I would like to see more videos on this type of boiler.
My problem is when it turns on and more than one valve requires heat, the burner starts moaning at a certain point, what could it be?
FOR MODELS MG-50-E TO MG-150-E
i have problems with the hot water tanks, the hot water from the boiler once gets just past the circulating pump stops, all my radiators work fine expect the domestic hot water
How do you reset it
So the thermostat has no control of the boiler or the pump? The thermostats only control the Valves? Also what would happen if all of the valves close and the pump is still running?
This why you notice the supply and return is joined together. Mine also has a ball valve in the middle to keep a small flow going. I close the valve when cleaning the water and removing air.
So what is the heat source? Oil, propane, methane, kerosene, wood? Thanks
NG: Natural Gas
Did I see your Water Pressure at only 10psi ? for it to be between 1 or 2 BARs ( 14psi = 1 BAR) that would be 20+psi It so happens mine is only 10psi too -- How do you increase the water pressure ? Show me that for an MG75( very similar to yours) and I'll send you lots of money that I would otherwise throw at a HVAC guy.
Add more water to the system. It will then increase the pressure.
That's a lot of parts in there to break. Some of those wires are gonna need to be shorted out to get that thing to work. Sensors, paddles, fuses.... not necessary, just get yourself a fire extinguisher or two! 😕
