Climate control for the space where guests sit, indoors and out. Propane glass-tube heaters of 11–13 kW and a 13–19 kW diesel radiant heater keep a terrace in use into the cold months. Indoors, a ceiling heat recovery unit brings filtered outside air into a dining room or guest room without throwing the heat away.
The glass-tube heaters burn propane at 37,500 BTU (11 kW) and 42,000 BTU (13 kW) and need no wiring, so they move with the terrace layout. For a larger open area the diesel radiant heater gives 13–19 kW from a 50–70 L tank, with a thermostat and tip-over and overheat protection.
The glass-tube patio heaters ship in sets of 20, the diesel radiant heater from 5 units and the heat recovery unit from 2.
No. It swaps stale indoor air for filtered outside air and passes the warmth of the outgoing stream to the incoming one, but it does not cool the room. The unit mounts in the ceiling void, runs on 110 V or 220 V and is controlled over Wi-Fi.
