You can install our positive head hot water booster pump under your kitchen sink and it connects directly, via two 22mm push-fit flexible hoses, to your hot water supply.
When the lever on the tap is opened the hot water booster pump automatically energises and increases your hot water pressure, giving improved water flow and allowing customers with a gravity/low pressure system to use a high pressure tap.
This hot water booster pump is quiet and compact, and has been specifically designed to increase water pressure to a household's hot water supply. The quiet AC induction motor is smooth and reliable, and the regenerative design of impeller is ideal for overcoming air pockets that can be generated in a shower system.
This type of hot water booster pump is ideal where the plumbing route includes multiple bends and elbows.
Our hot water booster pump has been manufactured in Denmark and will boost your hot water up to 2.0 bar.
The outlet pipe has a built-in flow switch which activates the pump when it detects water flow, and deactivates the pump when the flow stops.
The flow switch requires a minimum of 0.5 litres flow per minute to operate. Two 22mm push-fit flexible hoses are included.
It has a compact design, low running noise and includes anti-vibration feet.
The pump can either be wired directly into a fused spur or you can plug in the 1.4m lead like a dishwasher.
** Hot water should be NO hotter than 65°C when using this pump. If your water is hotter than 65°C and the pump fails, we would not be able to offer a refund. **
***Must not be connected directly to mains water supply.***
