Home > Oil Appliances > Domestic Heating > Combination Domestic Hot Water and Heating System
An affordable way to convert from electric to oil heating! If you have forced air, now you can heat your water with oil, and your air with hot water. Introducing the new combination hot water/central air heating and cooling system from Aero.
The perfect solution for heating conversions and new home construction. This dynamic combination begins with Aero's industry leading oil-fired water heaters. With computer assisted design and high output oil burner efficiency, our water heaters are engineered for high volume, rapid recovery and reliable performance. And all our water heaters have an available immersion aquastat for better control of the system.
When thermostatically triggered, a small pump forces hot water to flow into
the handler unit. The space-saving design of our air handler doesn't require
external venting. This allows for easy installation, even in small or awkward
spaces. Once the hot water is in the handler, the high-efficiency coil heats
the surrounding air. Finally, the fan in the air handler forces the warm air
into the ductwork and evenly throughout the house. You can even add an air conditioning
coil to the handler for a complete hot/cold central air system.

Notes
1. Sizing is extremely important all installations must have an accurate
heat/loss calculation done.
2. Installations must have 3/4" piping from the water heater to the air
handler.
3. Piping length should not exceed 200 feet.
4. Insulate all piping.
5. Solder all connections using lead free solder.
6. Hating BTU is calculated using 140F entry water temperature.
7. Mixing valves must be used.
8. Heating BTU will not exceed output of water heater.
9. Larger water heaters may be used where domestic water demand is high.
