Thank You for your help and support. - Навчання та стиль
Awesome DIY! in addition to pressure reducing valve others have mentioned you need... - U will also need a backflow preventer in the same spot to ensure that water does not mix with the domestic. Nice work! I put a system in 15 years ago, I need an upgrade so I'm watching all these vids to gain "confidence" 🙂 thanks for sharing!
Thanks for the information and good luck with your upgrade.
Those warm floors are going to feel good on a cold day. Nice system, thanks for sharing it. Be well my friend.
I just hope it works like it should first one for me.
I don’t know nothing about this type of heating, but from what I hear you and Julie’s should nice and cozy this winter.
I sure hope I don't know a lot about it but I think it will work out thanks Frank.
Looks really good, great job 👏
Thanks Mark.
Kevin, that radiant floor heat is going to be soooo nice this fall/winter. I know you once mentioned a woodstove as well. If so, you better start searching. It took me months to get mine and it almost doubled in cost. Your place is coming along nicely.
Thanks Jesse.
Looks great!!!!!
Thanks John
The mass of the cold concrete will suck the heat out of the water till it heats up. Then the concrete will warm up and radiate, heat rises. Great job.
Thanks Terry, I can't wait to try it out.
Thats exactly how it works. I like to heat my slab to 60 degrees and do it in 60 degree ambient temp. When it gets colder outside it will keep up...as long as its sized correctly
Kevin did anyone mention to you about putting a pressure reducing valve on the inlet side. You should only need about 15psi ....
The water is coming in and with the check valve it could continue to fill until the relief valves pops....
I'm going to look into that thanks.
Yes, I agree. It will run fine with less stress if you set the pressure at no more than 15 psi when cold, which will give you 17 to 20 psi when at typical loop operating temperature of 90 to 100 degrees F. That is the way I run mine, using an instant electric water heater.
Also, you should have a pressure relief valve set at 30 psi, much less than for a domestic hot water tank.
And the psi needs to work at around 15psi last a lot longer pumps will push easier
Is your system as simple as this one? And, are you on electric or gas? Thanks! @@marktomlinson3448
Was your expansion tank super precharged? You should only have need around 10-12 psi, unless you're heating a tower.
Awesome mechincal install looks good...just put some brass between copper and steel...before you see that copper start discoloring black....sure sign of electrois happening...
Thanks for the tips!
Really cool! One comment for the future - heat-pump hot water heaters (e.g. hybrid hot water heaters) use significantly less power than regular hot water heaters and in heat-pump only mode a 50gal tank will max out at 400w of power instead of 4,5000w of a regular heating element. I don't know if you plan solar etc.... but maybe put that in the back of your mind for the future.
Thank you Kenneth.
Heat-pump hot water heaters typically exhaust their cold air into the living space. They make heat pump boilers that exhaust their cold air outside with the evaporator being outside.
65 psi is crazy man all you need is 15
Thanks for the comment.
Need a pressure reducing valve
Hey Kevin, thanks for putting this video. I'm thinking to build a similar system. Can you please tell the tank size and sq.ft of floor you're heating?
960 ft inside the house 36 gallon hot water tank lots and lots of insulation under the floor and walls and roof.
👍👍👍
Thank you Pete.
Steel expansion tank hooked directly into copper....electrocis my friend!
Thanks
Where did you get your baffles? Thanks
Menards thanks for the comment.
Watching, i see what confused me most about your set up, is that your pump is on the outfeed versus the return. The return is cooler, therfore less wear and damage to your pump than the hottest point of the system.
Interesting concept. Can you use any old hot water heater??
I did research on the pump and it won't hurt it being on the hot side, and yes i just went to lowes and picked up a 36 gallon water tank and i don't have any issues with it.
I’m curious about how well the electric heater is doing. I installed a system that was already set up. Everything works fine. What temperature do you have the hot water set to? I was thinking it should be around 90 degrees. The electric heater I used quit. It was an on demand thing.
My heater is set on 120 but it run about 90 degrees I just use a hot water tank it works great no issues so far.
Do you need to worry about using oxygen barrier pex with these systems?
Thanks!
I'm sorry I didn't put pex in the floor they did not sure.
Can you measure the kwh of electricity you use with that water heater in a 24 hour period? Im dying to compare cost per kwh electricity ~vs~ cost per BTU of oil at current market prices.
I wish i could help you out but i don't know how to do that sorry.
That's a complicated looking system. That's why I don't have it.
Nice system though.
Very easy to work on nothing to it thanks for the comment Daryl.
Its actually quite simple.
What kind of water heater are you using?
Just a 36 gallon hot water tank from Lowe's.
How's your electric bill ? Thank you for the video.
Last month was $200.00 I didn't think that was too bad for as cold as it was maybe next month will tell us more thanks for the comment and watching.
@@Robinson-Homestead200$ more than it was before the system? How much did the system add to your bill, thank you
You put 65 psi on an expansion tank that’s precharged at 12psi?? You probably destroyed the bladder in your expansion tank. I don’t get why people think it’s a good idea to use a water heater for space heating. They’re not efficient, they’re not rated for space heating and they don’t meet code.
Thanks for watching.
They can work fine, but the pressure should be set much lower, at about 15 psi when cold, and must use a lower pressure safety release valve set at 30 psi.
Just don’t do it guys. Stay safe.
Hire a professional if necessary
Sorry my friend it's working great Love it thanks for the comment.
