System Boilers

If you live in a home with more than one bathroom or you require more hot water than can be provided by a combi boiler, then a system boiler could be your perfect heating and hot water solution.

What is a system boiler?

The major components of the heating and hot water system, including the pump and expansion vessel, are built into the system boiler, and a sealed hot water cylinder in the system provides hot water for the taps and heats the radiators. There is no need for a feed or expansion cistern in the loft, which saves space and eliminates the risk of any leaks or frost damage to pipes and tanks.

System boilers provide a high flow rate of hot water to deliver quick filling baths or powerful showers, thanks to the in-built pump, without the water running cold elsewhere in the house. They are compatible with unvented hot water storage cylinders, such as Megaflo Eco from Baxi’s sister company Heatrae Sadia

Since the Building Regulations changed in April 2018, known as Boiler Plus, all boiler installations must include a timer and room thermostat.
