Removable front panels for serviceability

1" thick insulation

ECM motor with continuous low speed blower

18" by 18" by 3 row water coil

3-speed Grundfos water pump

To be compliant with most building codes, If there has not been a call for heat within a 12-hour period, the circulator will turn on for 2 minutes thus eliminating risk of bacteria.

Pump "Pre-charge" on a call for heat, turns pump on prior to blower in order to get warm/hot water in the coil thereby avoiding blowing cold air throughout the house

Blower "Scavenge" keeps the blower on after the call for heat [from t-stat] has ended so that valuable energy in the water coil is used up, not wasted
