Hi Terry

If you scroll down on the main page, there is a "Post a new message" form at the bottom.

I guess my question is: "does the system do anything that it's meant to do, properly?"

I'm not being glib, but you've mentioned two issues with the system, but it's hard to tell if the system is mainly working OK except for these two issues, or if these are the only things that the system does, and it's not doing either of them well.

The likely causes would be easier to identify if we know whether it is a full or partial fault.

As for the slow radiant floor, this will depend on what is below and above the concrete slab. If it's bare slab-on-grade with an insulating padding below the wood floor, I would totally expect that it would be pretty slow to respond. If the concrete is on 2" of insulation and the wood is on bare concrete I'd expect it to be faster to respond, but it's still hard to eliminate the tiny air gap between the concrete and wood. It also depends on the delivered water temperature....

Post some more deatils: eg: model numbers and functions performed and I'm sure you'll get plenty of suggestions.

Phil.

This site is all about building a cool, energy efficient house, that makes maximum use of earth sheltered design, passive solar heating and cooling, geothermal exchange energy management, and right sizing of the house for it's designated use. The home's placement is on a south-facing hillside in Deep Creek Lake, Maryland. This site describes the design process, the technologies used and the expected results. We also have a comprehensive Links Page for anyone who is also interested in designing a similar project.
