Baxi 825 combi boiler review – Is it any good?

The Baxi 825 combi gas boiler is reliable and efficient. It has an efficiency rating of 93% as well as an ErP A-rating to heat and hot water. 

This combi boiler can help reduce not only your carbon footprint but also your energy costs. All the Baxi 800 range of combi boilers are also now hydrogen ready which means they are capable of running on up to 20% hydrogen blend with natural gas.

Replacing a boiler is a big decision in terms of cost, but also for getting the right output for your home. There are absolutely loads of new boilers to choose from and this Baxi range is one of the best.

Baxi 825 combi boiler outputs

With a 21.2kW output for central heating, and 25kW for hot water, the Baxi 825 is one of the weakest models in its range. It is ideal for homes with up to 10 radiators and one bathroom. You might consider the Baxi 830, or the Baxi 836 if your home is more energy-intensive.

Is the Baxi 825 combi right for my home?

Combi boilers work well in smaller homes that have limited space because they don’t require additional hot/cold water tanks. Because they combine the central heating system with water heating into one unit, this is possible. The boiler unit is lightweight and compact, making it easy to install.

The Baxi 825 is a high-efficiency boiler that will save you money all year. Its compact size and low weight will also help you to save money on installation.

If you have a larger home and you have your heart set on a Baxi boiler, then we recommend the Baxi 836 combi which can cope with higher hot water demands.


What features does the Baxi 825 boiler have?

Baxi 825 has a ADEY Micro2 magnet system filter, brass hydraulics blocks, built-in standoff frame, easy-fill permanent linking link which makes topping it up simple, optional Usense smart control, opentherm interface and IFOS compatibility. It also features a simple hanging bracket. You can also control the boiler using your smartphone or tablet.

The standard warranty on the Baxi 825 lasts for 10 years. You can rest assured that it will be a reliable appliance in your home.
