This affordable LPG combi boiler has compact dimensions and no requirements for additional components to provide hot water, so it’s also ideal for smaller homes and properties where space is limited. 

How Much Does this Boiler Cost?

Baxi’s Duo-tec Combi LPG boiler has an output of 28kW and will set you back around £875. The price you pay will depend on who supplies this LPG combi boiler. However, you also have to pay the installation cost. We suggest you look around and get a quote from local and national installers to find the best price. Make sure your quotes are fixed and come from only Gas Safe registered installers. 

How will I know if this Boiler is Suitable for My Home?

This LPG combi boiler from Baxi comes with a heating output of 28kW and is ideal for homes with up to 15 radiators and only one bathroom. It is designed for properties not connected to the main gas line but still works similarly to a natural gas boiler. But if you choose to get an LPG combi boiler installed, the fuel has to be delivered to your home. 

If you’re unsure whether an LPG combi boiler is suitable for your home, be sure to contact a Gas Safe registered engineer for some advice. They can also help you determine the correct size LPG combi boiler to match your demands.
