Baxi 200 Heat

The Baxi 200 Heat is a conventional boiler that is available in 5 heat outputs and designed to suit homes of all sizes.

Compact and lightweight, the Baxi 200 Heat can be fitted in a kitchen cupboard and will blend in with all other modern appliances. It boasts an A rating for efficiency and is compatible with Megaflo Eco Cylinders to provide higher levels of hot water performance and end-user comfort. Plus, this boiler is easy to install and maintain, so it may even save you some money on installation and annual servicing costs.

How Much Does this Boiler Cost?

The amount of money you’ll need to part with will depend on which heat output you need. Baxi’s 200 Heat comes in five different outputs of 12kW, 15kW, 18kW, 24kW and 30kW to suit small, medium and large homes. Typical prices range from £650 to £770, with the highest output being the most expensive. Also, you’ll need to find out how much the installation is going to cost, as this won’t be included in the price of the boiler.

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

It’s a heat only boiler (also called regular, traditional or conventional boiler) and is best suited to homes with a traditional heating system already in place because it needs to be installed together with loft tanks and a hot water storage cylinder. If your property is blessed with multiple bathrooms, the Baxi 200 Heat will be able to cope with a couple of showers running at the same time. Obviously, the larger the home and greater the demands, the higher the output will need to be.

The only way to know for sure if this boiler is the right type for your home is to ask a Gas Safe registered engineer. A qualified heating professional will need to visit your home and assess your requirements in order to recommend not just the correct boiler type but also the best size (kW output) for your household.

Is it a High Efficiency Boiler?

It certainly is. The Baxi 200 Heat has an efficiency of 89.2%, making it an A-rated gas heat-only boiler. You should know that it’s also a condensing boiler, which means it will recover more heat than your old boiler and save you more money on your energy bills. But that’s not all. This boiler can be used with an optional Megaflo Eco Cylinder for the best possible heat retention and energy efficiency. It’s also an Energy Saving Trust endorsed boiler.

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

Baxi’s 200 Heat comes with a range of user controls, such as a reset button, operating mode selector and a switch that lets you adjust the central heating temperature. Additionally, it has an LED display that lights up to inform you about the boiler status and any faults if and when something goes wrong. The boiler doesn’t require any extra wires and is supplied with a wall-mounting plate and a choice of flue lengths for hassle-free installation. And because all of the components can be accessed via the front and sides of the boiler, service and maintenance are often straightforward.

How long is the Warranty on this Boiler?

This heat-only gas boiler by Baxi is backed by a 3-year parts and labour warranty as standard.
