Boilers
Choosing the right new boiler for you
Every home is different, so we don’t fit one boiler for everyone. We look at your property and your hot water needs, then recommend from these types:
- Non-Condensing Boilers:
An older type that may still suit some heating setups. - Condensing Boilers:
Highly efficient boilers that help cut your energy bills. - Open Vent Boilers:
A good fit for homes with several bathrooms. - System Boilers:
Steady heating and hot water for larger properties. - Combination Boilers:
Compact combi boilers giving heating and hot water on demand. - Gas Boilers:
Run on mains gas for reliable, cost-effective heating.
