Fireplaces with water circuit

A fireplace with water circuit may serve as a main heating system or as an alternative one.
When a fireplace is the only heating device, it can heat a house of up to 400m² in area and provide hot water for household needs..

When a heating system includes electric or gas heaters, it provides for the main heating devices being turned off while the fireplace with water circuit is being turned on, i.e. the main heating device is automatically turned off when the specified temperature is maintained using only a fireplace. For example, when using a fireplace in summer a heating option may be turned off and a hot water one on.
Thus, a problem of useless wood burning in conventional fireplaces can be solved. Besides, expanses for the energy resources would be decreased.
