radiant

Hi all, Have enjoyed learning from these forums for many years, and finally ready to ask a question... Our new home on Cape Cod Massachusetts (Climate Zone 5) is very well insulated but has architectural feaures that are challenging - some vaulted ceilings and lots of large windows. There is...

Hi all! Short-time reader, first-time poster. I just moved into (renting) a Seattle-area townhouse and have realized my heating system is, unfortunately, a hydronic open loop (in-wall forced air radiant) system using a standard hot water tank that is shared with the domestic water system. The...

Hello, I am finally diving into utilizing the pex tubing in the slab for our basement versus the duct work from the forced air gas furnace. After finishing the basement last winter and spending more time down there this winter we would like to improve the comfort level during the heating...

Hi all, I’ve been lurking here for some time and am thankful for all of the knowledge gleaned, your generosity with your time is humbling. I’ve got a heating situation that I’d love to have some experienced eyes look over. 3.5 years ago my family moved into a “needs everything” home that was...

I’m building a new 2100sq ft home. All one level. I’ve received mixed input on what to use as far as a boiler, hot water heater and electric boiler for the system. The pex will be going in the floor joist. One proposal was also to use 7/8 pex and I’ve read some guys would never use that. What...

I have a question related to the radiant floor system I am installing. Context: The previous owner of our homes (two located on one property 60 feet from one another other) had ½ PEX oxygenated lines run throughout the entirety each structure. Both homes are Insulated concrete form...

Hi, I'm curious if there are any experiences/insight beyond standard troubleshooting for this issue. The most practical resolutions i've seen so far are to straighten the fins (which i've done) and to ensure the return pipe is not resting on any metal hooks which could create noise... I do not...

In our recently purchased approx 20 yr old house, we have an in-floor radiant heating system, that seems to work quite poorly, as in very slow to heat (like, half a day to get rooms up to temp). I suspect the previous owners either did not use it, or only used it supplementally. (house also has...

i have a hydronic radiant in-floor heating system. It’s actually partially heated by solar but that’s probably not relevant here. Several zones are not heating although the electric actuators show ON. I believe I must have some sticky valves but can’t find any maintenance info on them. The...
