What is (rule of thumb) Low temp?

Ed Lentz_2

I am just curious. I am a DIY'r I check in here most every day. I did not do an analysis and I plan on doing one. I have 1/2 pex staple up with plates and insulation on a wood floor. I have seen some of you mention low water temps. Just what would be considered Low? I have a injector with pump, outside reset. So my system seems to work very well so far. Just wondering if I should fuss with it some more, now that warmer weather is here.

Thanks

That's a relative thing, for one. But generally "low temp" refers to something in condensation range for a condensing heat source.. I believe below 130.

Of course, "low" for your wood floor stability may be more like 110 or 115.

Or "Warmboard Low" is below 100

Since you're using injection, I would speculate you are using a conventional boiler. So you're mostly looking for stress reduction on your floor system as well as consistent cycling under different load conditions... that is, if you need heat but it's only 50 degrees outside, that the system isn't OFF all the time, coming on for short burst. Instead you want the water temp to modulate down to the point where the floors are still not getting cold.. not hot floors, but not cold either. Long, smooth cycles.. great comfort. Short, hot cycles... not so good.

So for you, "low" would be water it takes to heat the space while keeping the cycles relatively consistent. .02 here
