How much this boiler will cost you is dependent on the output you need and which heating engineer or company you choose to carry out the installation work. You also need to factor in the installation cost, so it’s a good idea to shop around and get a range of quotes to find the best deal.
How will I know if this Boiler is Suitable for My Home?
A combi boiler, such as the Baxi 800 Combi, is ideal for homes where space is tight because it takes water directly from the mains supply and therefore doesn’t need separate tanks or a hot water storage cylinder. Even though you can save space with a combi boiler, it will struggle to cope when you want to run more than one bath or shower at the same time. Since this combi boiler comes in three outputs, it’s suitable for small, medium and large-sized homes.
The higher your demand for heating and hot water, the higher the kW output you will need. Choosing the correct boiler type and size for your home is incredibly important, so we recommend you consult a qualified Gas Safe engineer before you purchase the Baxi 800 Combi.
Is it a High Efficiency Boiler?
Yes, it is. The Baxi 800 Combi is an A-rated boiler that meets the energy efficiency ratings required for Boiler Plus compliance. Boiler Plus is a legislation that was introduced in 2018 to improve the energy efficiency of homes in the UK. It aims to ensure all new gas boilers have an ErP efficiency of at least 92% and are installed with either a flue gas heat recovery unit, a smart load or a weather compensation control.
Does this Boiler have a Good Range of Controls and Features?
It sure does. Baxi’s 800 Combi has tough brass hydraulics and comes with an Adey Micro2 magnet system filter to protect both the boiler and heating system. This combi boiler also comes with a simple hanging bracket, a built-in stand-off frame for neat installation and flue options up to 20 metres. And that’s not all. The Baxi 800 Combi is IFOS (In Flue Outdoor Sensor) compatible to comply with Boiler Plus requirements and has an OpenTherm interface to enable you to control your heating from a smartphone or tablet.
How long is the Warranty on this Boiler?
