If your hot water system seems low on pressure, the Silverstone range of Hot Water Pumps is the answer. Gravity fed systems can suffer from low pressure especially in 2 storey houses where bathrooms are upstairs. This pump senses water flow and automatically kicks in to boost the pressure up to 10bar. This pump incorporates a flow switch which starts or stops the pump when a tap is turned on or off.

The flow switch is operated by a gravity flow of 2.0 l/min. The gravity flow at all fittings which require boosting should be checked to ensure that the pump will operate when the outlet fitting is opened. The pump should not be operated for long periods without flow through the pump. Minimal maintenance of the pump is required. Periodically the flow switch may need cleaning depending on operating conditions. That will give you an amazing shower and mains pressure hot water at all your taps (depending on the location of the pump).

Can be used to increase the water pressure of all domestic and commercial showers, baths, sink and taps.
