Baxi 636 Combi LPG Boiler

Ideal for homes off the mains gas network, the Baxi 636 Combi LPG is a compact British-made combination boiler. 

If you live in an off-gas grid home and want to replace your boiler, the Baxi 636 Combi LPG could be the perfect heating system for you. It has a high hot water flow rate, features top quality brass components and is small enough to fit inside a kitchen cupboard. This highly efficient LPG combi boiler is also easy to use and can be operated using a smart control via an app on your smartphone or tablet.   

How Much Does this Boiler Cost?

The Baxi 636 Combi LPG is a 36kW output model with a price tag of around £1,100, not including the installation cost, which can vary significantly. You’ll need to get a quote from local and national installers to find the best price on the boiler and installation. Make sure you only contact Gas Safe registered installers, and ask each of them for a fixed-price boiler installation quote. 

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

Baxi’s 636 Combi LPG with 36kW output is suitable for medium and large-sized homes in off-mains gas areas because it does not use natural gas as its fuel source. This LPG combi does not require a tank in the loft or a hot water storage cylinder and is small enough to fit into a kitchen cupboard, making it ideal for homes where space is limited.  

Keep in mind that an undersized boiler will not meet your heating and hot water demands, and an oversized boiler will cost you more money than is necessary. Always consult a Gas Safe registered engineer to help you determine a suitable boiler size/output for your home and needs.

Is it a High Efficiency Boiler?

Yes. The Baxi 636 Combi LPG has an ErP rating for heating and hot water and is an Energy Saving Trust endorsed appliance. If you currently have an old boiler and decide to replace it with this model from Baxi, you should save money on your fuel bills. 

Does this Boiler have a Good Range of Controls and Features?

Despite being built using top quality brass components, the Baxi 636 Combi LPG is lightweight and weighs in at less than 30kg. It has a control panel with a display screen and comes with an Easy-Fill permanent filling loop to enable you to top up the central heating system pressure. This LPG combi boiler has built-in pipes behind the facility within the boiler casing to ensure it looks tidy and front access to all of the components to help make servicing and maintenance quick and straightforward. The Baxi 636 Combi LPG is also compatible with a range of optional accessories, including the Baxi uSense smart room thermostat that allows you to control your heating from your smartphone. 

How long is the Warranty on this Boiler?

The Baxi 636 Combi LPG comes with a 7-year parts and labour warranty as standard for extra peace of mind.
