Breaker is 60amp, wired with 6-3 copper Maybe overkill at 15kw, but this boiler had some features I liked, and it's a modulating boiler, so it only fires up what it needs. Cost me about 1000$ cdn. If they ever bring natural gas to my street I would probably change.

Hi, the pressure overflow extension is on my to do list, along with building a better bracket to support some of the weight. Green hoses are fill/bleed hoses. Just kept filling from the right valve until no more air bubbles came out of left hose.

hey hulkster, I ended up buying a dettson 15kw modulating boiler. http://www.dettson.ca/en/products/hydra-revolution/ Was considering propane but with last years fluctuating prices and the issues of gas line permits, install, condensate drains, open flame, venting etc. I just went the easy way...

My garage setup is similar, 3/4 copper feeding 4 loops of 1/2 pex, 230-250 ft runs. On the lowest setting, 2 to 3 gpm gives me 20 degrees of delta with outside temps of -15c and slab temp of 20c I thought I didn't have enough flow with that pump until I figured out the flowmeters actually turn...

Hey Anthony, I see you are also in Ontario, so Hydro one has a cool little feature on their website where you can graph electrical usage in kilowatts or dollars. The first 24 hour period cost me 12 bucks to get it to 20 degrees c. Original slab temp was 0c and I just ran it 24 hours on high...

pics as it is now. Floor thermostat is set at 67. What are you guys using for a target slab temp? I also have the outdoor sensor which I haven't wired yet.[/URL][/IMG] [/URL][/IMG] ok so i still need to build the support for the expansion tank and put an extension on the blowoff (?) valve. I...

I picked up a pressure gauge, and with 13psi in the system, there is 18 psi between the pump and the manifold, so am I correct in assuming there is 5psi back pressure or 11 ftf head? With no pressure in the system and the pump on high, there is about 4psi between the pump and manifold? Either...

Do you mean the pressure relief on the upper left side of the boiler? i assume this is a safety issue so that in the event of a pressure spike, the scalding liquid won't spray everywhere? Thanks

Hey Steve, From what I could figure, my 900sq ft slab should need 50,000btu so I think I need 5gpm/4 loops for 1.25gpm per loop. So thats how I came up with the 8ft head. Does this make sense? Anyhow I was thinking of going to pick up a pressure gauge to tee between the pump and manifold... thanks

Hi, So I got everything plumbed and filled, bled the air out into a clear container of water until no bubbles only fluid came out. Ended up removing the 1 way valve on the outlet side of the pump. Fired it up last night at about 5pm, supply temps are 110F and return temps are currently about...

Thanks Anthony, So I was going to build a bracket that attaches to the horizontal stud near the bottom flange of the pump to support the pump and the expansion tank. The pump has one of those plastic check valves on the outlet, is that good enough? I was thinking the fill/bleed as high as...

This is my first attempt at setting up an infloor heat setup, With a lot of searching and reading and weeding I think my plumbing is ready to be finished up. So I have a 15kw modulating boiler feeding 4 loops of 230-250 ft each. Hot water exits the boiler via 3/4" copper pipe and feeds into a...

thanks guys. I like anthonys answer. Simple like me. Its like checking all the weather channels until you find the forecast you like. But seriously, IF 3/4 is too small what will i see? Too much temperature drop cold vs hot? The pump building too much pressure or working too hard?

A bit of info on my garage build. 1000 ft of 1/2 pex, 4 loops of 250 ft plus or minus 10 ft. I have a 15kw boiler and the pump, fittings and taco air separator are all 3/4" npt fittings. So I was going to plumb all the primary tubing with 3/4 copper but would this be too small to feed 4x 1/2"...

I read that somewhere too, maybe on this site, but I don't get how that would work. In the automotive and diesel world, distilled water is recommended, in fact Caterpillar premixed antifreeze uses distilled water. The logic being that the minerals in well water could eventually cause scale and...
