Thermolec Plenum Heater Model HPX

The HPX Modulating Plenum Heater is advanced technology ideal for dual-fuel/ hybrid HVAC systems. Hybrid systems that utilize an air source heat pump with an HPX plenum heater can provide up to 50% savings on annual heating costs compared to conventional forced air heating systems. The HPX plenum heater maximizes an air source heat pump’s efficiency and savings by modulating it’s output and providing additional btu’s as needed on colder days, allowing the heat pump to operate even below the comfort balance point. HPX works with any air source heat pump and/or gas furnace.

"HPX can be used with a heat pump or four wire stat"
