Aquatherm® Combo Heaters! Now you can choose comfortable, efficient gas heat... without paying a premium or compromising valuable floor space! Sequence of Operation (heating mode): Combo Heaters Provide Solutions, Not Problems! When space heating is needed, the wall thermostat energizes a small pump which circulates hot water from the water heater to the hot water coil in the Combo Heater.
High Efficiency Benefits: The recovery efficiency of today’s natural gas water heaters ranges from 76 to 94%. As a general rule of thumb, the space heating efficiency of any water heater can be approximated by adding several percentage points to the water heater’s recovery efficiency. The efficiency gained by these systems comes from the fact that: valves (if any) are required. To determine approved indoor/outdoor matches, go to www.firstco.com or contact the factory.
