Can I connect the FREE HEAT MACHINE to a pressurized heating system?
Yes! A brazed plate type water-to-water heat exchanger is installed on your boiler piping so that one side of the exchanger is connected to the furnace (which is a vented loop) and the other side is connected to your existing pressurized system. The exchanger pre-heats the water in the pressurized system just before it enters the boiler so that your existing boiler acts as a backup heating source. The heated water is circulated through your existing radiators and/or baseboard heaters as it normally does.
