At Heatmaster London, we provide full and thorough consultations, so you don’t need to worry about making tough choices. However, here is an overview of the three main types of boiler that we offer.

Combi Boilers
These compact boilers generate heat only when required, so are very energy-efficient. They are small, and ideal for one-bathroom or small homes.

System Boilers
For homes with two bathrooms or with higher hot water usage, system boilers are still relatively compact as they do not require a hot water tank.

Open Vent Boilers
These larger boilers are ideal for homes with multiple bathrooms and a higher rate of use. However, they are also compatible with modern energy-reducing systems, such as solar power.

For boiler changes, we also have a comprehensive floor-standing product range. This is without doubt the simplest and quickest way to get a replacement boiler in quickly, and at a low cost.
