The Baxi 830 Combi Boiler is built to last. Additionally, it’s also compact and in the “lightweight” category amongst other combi boilers.

For the hydraulics block, they used quality brass. Therefore, it should be able to serve you for a couple of years without any serious issues.

Fuel and efficiency

Straight off the bat, we recognize the Baxi 830’s efficiency. With an efficiency rating of 93%, it’s top tier as far as condensing combi boilers are concerned. Additionally, it has also earned the ErP A-rating for both hot water production and central heating.

In case you were wondering, the Baxi 830 Boilers run on natural gas fuel. Nevertheless, they are also certified to run on a 20% Hydrogen blend.

Power output rating

The Baxi 830 Combi Boiler is part of the Baxi 800 series that comes in two output variants—The 25kW and 30kW models.

Although the 25kW variant is available, we don’t recommend it (especially if more than two people live in the household). There’s a chance it won’t be able to cater to all your heating and hot water requirements.

On the other hand, the 30kW variant is better. Although it’s not the most powerful, it should be able to sustain medium-sized homes—It can operate up to 15 radiators and supply hot water at a reasonable rate of 12.2 litres per minute.

Additionally, we understand that some prefer system boilers with hot water cylinders. You’ll be happy to know that the Baxi 800 line also has system models.


No worries. Its installation process is nice and easy. Weighing at 29.5kg, it shouldn’t require more than one engineer to install. As far as time is concerned, it will take anywhere from 1 to 3 days to install. Of course, your home’s layout and complexity will dictate the exact time.

It comes with a simple hanging bracket that will see it stick to a wall. Dimension-wise (700mm Height by 390mm Width by 285mm Depth), it’s compact enough to fit in your standard kitchen cupboard. You’ll never have to worry about the “odd-looking” boiler cramping your home’s decor.
