Energy for life

This fireplace design combines the cast iron heater tradition of modern hot-air fireplaces with a green energy heat recovery, by harvesting the heat of the flue gas, in order to heat up the water in a geyser or buffer tank for shower and space heating, thus reducing the electricity bill.

This is possible due to an embedded heat exchanger, where the water flows through, as the flue gas is quitting the burning chamber.

The firebox is closed by a glass cast iron door, so it is possible to heat without the risks associated with an open fire. The ceramics and the glass are supplied by leading manufacturers and are guaranteed to function safely.

These fireplaces are made either as a vertically sliding or side-opening unit. The cast iron is protected by a heat resistant matt paint. The fireplaces are equipped with a manual combustion air regulation valve.

Create the ultimate center piece for your house and home.

How it works

Conventional fireplaces waste huge amounts of heat energy, which is carried away by flue gases through the chimney. These losses amount to up to 2/3 of the nominal heating capacity of the fireplace.

An internal heat exchanger mounted in the flue gas stream absorbs the heat energy contained in those hot flue gases, by water circulating through it. The water flows back to a buffer tank, which functions as an energy storage.

From the buffer tank the water can be circulated into a water based under floor heating system, being able to heat up to 250 m2 of space in a building or produce hot water on demand for domestic use, such as shower and cleaning.
