Tunnel Kuni Booster

For your home:

Connect our Tunnel Kuni Booster to a storage facility to store your hot water:

- Connect to one of our Tunnel Storage Tanks, which are suited to the heating capacities (see table below)

- Modify an old oil drum for 100L or 200L capacity

- Connect directly to an immersion heater cylinder

- Connect to an existing solar heating system, “boosting” your hot water on cold, cloudy days when solar energy is low

- Note that a storage facility is extremely necessary when installing a Tunnel Kuni Booster; it MUST NOT be connected directly to pipes supplying water to your bathroom/kitchen etc. 

- Choose LL (galvanised) option for use with impurified borehole water

- Tunnel Kuni Boosters can withstand pressures of up to 40ft head
