How To Heat Both My Floor And Sepate Domestic Water

The reason for this is to have the two water uses separate.

How to heat both my floor and sepate domestic water. The water heater to use with radiant floor heating should be a high efficiency unit. The idea here is to prevent domestic water from getting contaminated by stale water that sits uncirculated in the heating system during the off season. One option is to keep domestic hot water completely separate from water that s part of the heating system using a heat exchanger. The two systems are basically tied together.

The best kind is one that has a sealed combustion chamber and an external heat exchanger. In the summer water will stagnate for the floor heating and if it mixes with your regular water it won t be good. Hot water from the boiler is circulated through radiators or a hydronic heating system to warm the ambient air. As you can see this allows the boiler to heat a tank of potable water which in turn can provide domestic hot water and floor heating in an open or closed configuration.

A dual purpose system relies on only one water heater to supply both the hot water requirements for the home and the warm water needed for the radiant floor heat. Normally the wood boiler is plumbed to a heat exchanger see drawing above. Even if only part of the home uses.
