This pump will increase the flow and pressure of the hot water so that you can enjoy a comfortable shower and use the washing machine or hot taps efficiently. The pump has a stainless steel body and is fully automatic with an in-built flow switch so when you turn on the hot tap, the pump starts automatically and stays on until you turn the hot tap off.

Your electrician will need to connect the pump to the 240v power and your plumber will need to install and commission the pump. Supplied with 3/4" male BSP unions as standard.
