This kit requires you buy a Combi boiler from us to receive the 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. A good match for this adapter is the NKC199N natural gas combi 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).

This includes:
(2) 1" PEX to 1" FIP fittings
(3) Wall clamps to mount the cable from the adapter
(1) Lochinvar bypass jumper cable
(1) Combi Adapter
