we are installing two systems, one is dedicated to radiant the other hot water, sorry should have mentioned that earlier. i thought i heard that most building codes won't let you do a system like that anyways?
Why? What is your heating load?
You don't need 2 different systems, you just can't use your Domestic Hot Water as the 'heating agent'.
You can use your boiler to heat both your house and your DHW, you just need to use a Heat Exchanger in your hot water storage tank. You won't be drinking or showering in the same water that is flowing through your floor. |
