Baxi 100 Combi

The Baxi 100 is a compact A-rated gas combi boiler that is suitable for kitchen cupboard installation and can be controlled using a smartphone or tablet.

If you need to replace your existing boiler and are on a tight budget, the Baxi 100 Combi could be ideal for you. It’s doesn’t take up much space, making it suitable for not only flats but also small to medium homes that don’t have the highest heating and hot water demands. The boiler will fit in a 300mm kitchen cupboard, is easy to use and service, and can even be operated using a uSense smart room thermostat that allows you to control your heating from a smartphone.

How Much Does this Boiler Cost?

As the Baxi 100 Combi is available in outputs of 24kW and 28kW, the price will depend on which kW output you choose. The boiler isn’t as expensive as some other combi boilers on the market and typically costs between £680 and £730 including VAT. You need to be aware that this is just the cost of the boiler alone, so you must remember to find out the installation cost as well. We recommend you do some research and get several quotes because, like always, prices vary from one supplier to the next.

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

This boiler is a gas-fired combi (or combination boiler), meaning it doesn’t need to be installed with a separate hot water storage cylinder or cold water tank. Because of this, the Baxi 100 Combi is perfect for smaller properties and homes with limited storage and loft space. Also, it only heats water on demand and only uses energy when you actually need hot water. As most combi boilers don’t cope well with two showers running at the same time, they aren’t the best choice for homes with more than one bathroom.

To know for sure, you must seek advice from a Gas Safe registered heating engineer. A qualified professional will assess your property and requirements in order to recommend the correct boiler type and size for your apartment or house.

Is it a High Efficiency Boiler?

Yes. The Baxi 100 Combi is an A-rated natural gas boiler with a great efficiency of 90.9%. It’s also an Energy Saving Trust endorsed product. If you choose to purchase the optional uSense smart room thermostat with 3-year warranty, you’ll be able to monitor how much energy you’re using, which should help to save you more money on your energy bills.

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

Baxi’s 100 Combi comes with concealed user controls, which include a reset button, system pressure gauge and separate hot water and central heating temperature controls. It has a clear LCD display and is compatible with a variety of optional controls, such as the uSense smart thermostat, plug-in 24-hour digital timer and RF digital 7-day programmable roomstat. When it comes to features, the boiler has an integral frost thermostat and front access to components for hassle-free servicing. Other features include a choice of flue lengths and accessories so that the boiler can be wall-mounted pretty much anywhere you choose.
