Radiant Temp Change Time

I'm assuming you're talking about how long will it take to come back from a set back. The colder it is the longer it will take.

Our recommendation with hydronic heat here in upstate NY is to not use set backs. With your new radiant system you're going to have a very economical system from the get go. Why take a chance on a pipe freeze or long lead time for recovery. The reason to spend the extra money on a radiant system is comfort. Enjoy it. :)

    Radiant Temp Change Time

    Hi everyone. I think I am going to have a new radiant floor heating system installed in my home. It will replace a nasty forced air system. I have grown up and always loved hot water heat. I don't have much expierence with radiant. I know that is does take much longer to change temps than baseboard or radiators do. I have 1/2" plywood subfloors, Pergo flooring. Joists 16" on center. I believe the heatloss calc's came up with 128 F water. What kind of time can I expect to gain say a degree? Could I gain a degree in one hour? Thanks.
