Mainsboost VariQ - Whole House Booster Pump The Mainsboost VariQ offers a variable speed, intelligent, energy efficient and quiet water boosting pump. The Mainsboost VariQ is designed to boost water performance from a cold water storage tank, roof tank or ground tank in domestic and light commercial applications and is ideal for many properties with up to 3 floors and up to 10 outlets in operation simultaneously. Even if multiple outlets, showers and appliances are running at the same time, the speed of the pump will adjust automatically to meet demand without any noticeable drop in water pressure.

What is a water booster pump?

A water booster pump increases the pressure of an existing water supply to give stronger flow at taps, showers and appliances. It can be a small inline pump fitted to the incoming mains, or a larger pump and tank set that draws from a break tank to feed the whole house. Boosters do not create water – they raise the pressure of the water already coming in.

What is the difference between an inline booster and a tank-and-pump booster?

An inline booster connects straight onto the incoming mains and is limited to 12 litres per minute under UK water regulations – examples include the Salamander HomeBoost and WaterBoost WB-Compact. A tank-and-pump booster, such as the Grundfos Home Booster or DAB Esybox with Esytank, draws from a break tank and can deliver much higher flow rates for larger homes with multiple bathrooms.

What is a variable speed booster pump?

A variable speed booster uses an inverter to adjust pump speed in real time to match demand. It maintains constant pressure as outlets open and close, runs more quietly than a fixed-speed pump and typically saves up to 50 per cent of the energy a fixed-speed equivalent would use. The DAB Esybox, DAB Esybox Mini 3 and Grundfos Scala2 are common variable speed examples.
