Installing an air conditioning “A” coil in a updraft air handler.
Here is a modulating electric boiler with a heat exchanger for the outdoor wood stove hot water. In this case, all zones in the house are low temperature so an injection pump is used to supply only the necessary temperature needed for the house through the use of sensors. An aqua stat is used for the automatic back up.
Please bear in mind many of these pictures are “during construction” and not complete. Here is a boiler heating system being built that uses an electric modulating boiler wired on Dual Fuel as the main source of heat. The gas boiler on the right will automatically turn on as back up heat when the utility company interrupts power to the electric boiler, all with no input from the homeowner.
