What is a combi boiler system?

A combi boiler heats water without the need for stored water tanks or cisterns. They are normally located on a wall close to the incoming cold water mains supply.

 

The system is completely sealed, so the pressure of the mains water will directly affect the flow of water through your showers and taps.

 

If you fear your system is underperforming, HomeBoost is an intelligent pump that can boost your mains water pressure. It automatically adjusts to the incoming water pressure and flow level, increasing your water supply by up to 12 litres per minute and boosting your pressure up to 1.5 bar.
