How To Heat Both My Floor And Sepate Domestic Water

One option is to keep domestic hot water completely separate from water that s part of the heating system using a heat exchanger.

How to heat both my floor and sepate domestic water.

The reason for this is to have the two water uses separate. The same water that ends up in your hot shower or dishwasher for example has passed through the floor first. 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. Hot water from the boiler is circulated through radiators or a hydronic heating system to warm the ambient air.

The two systems are basically tied together. In the summer water will stagnate for the floor heating and if it mixes with your regular water it won t be good. The traditional boiler water may also be used for domestic hot water by directing the water through a separate integrated water heating unit before routing it to a fixture such as a faucet or shower. The water heater to use with radiant floor heating should be a high efficiency unit.

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. The best kind is one that has a sealed combustion chamber and an external heat exchanger. Even if only part of the home uses.
