State & Lochinvar Combi Boiler Adapter (Without Fittings)

COMBI Boiler's needs an adapter to work the HUG Hydronics In-Floor Heating System. This is that adapter. Now, with one huge COMBI Boiler, you can heat your house and your hot water with the same boiler. * Installs with 1 tool, about 5  minutes of work. How does it work?  Combis have a pressure sensor which our adapter replaces with a low water level sensor and air remover. The probe senses if the water is low. If it is it sends a signal to the purge pins to run the pump 3 seconds, raising the water level enough to purge any air. The water sensing probe gets stuck down a tube on the top, and the power cord goes down a hole and plugs into the circuit board of the COMBI Boiler. On the HUG Hydronics Tanks the black box slips in next to the thumb screws on the back. A hose goes into the tank and a connecting cord feed to the control board and plugs into the purge pins of the heater pump (usually pump #10).
