LifeBreath is a non-combustion hydronic furnace, with a built-in heat
recovery ventilator (HRV). The HRV creates a very efficient heat energy
transfer between the outgoing and incoming air streams. In winter, the
incoming cold air is warmed by the heat transfer of outgoing air, and
the reverse in summer. The two air streams do not mix, only the heat
energy is transferred through conduction in the HRV.
The
LifeBreath furnace then takes this pre-heated air and brings it up to
air delivery temperature by heating it with the available potable hot
water source in a closed loop. We're currently exploring the option of
using a solar thermal system to provide the hot water source. The
value of this system is that it can provide a continuous infusion of
fresh air while minimizing the energy loss from the outgoing stale air,
providing a superior system of high indoor air quality.
