Mistral Boilers Boiler Efficiency Rating, Repair & Service

Mistral - Boiler Efficiency Page

Mistral manufacture oil fired heating appliances and have now gained over 40 years of experience in the industry. A British company, manufacturing all of their products in Shropshire, Mistral offer a range of highly efficient boilers that produce low emissions.

Mistral manufacture a wide range of System and Combi oil boilers in several sizes to suit the needs of a variety of homes.

Combi Standard

Their Combi Standard range offers condensing and non-condensing boilers that provide heating and hot water in a highly efficient way. Thanks to their compact design, they can be kept under a standard kitchen worktop so that they’re out of your way. If you prefer your boiler to be outside, then outdoor models are also available.

Should water performance be high on your agenda, then the CC4 model is said to produce almost twice as much hot water as any other Combi.

Combi Plus

Offering many of the same features as their Combi Standard range, Mistral’s Combi Plus boilers are separated from the Standard range due to an added 230V electric immersion heater that’s installed into the boiler heat store. Should there be an oil failure or the boiler isn’t in full operation, then the immersion heater can provide a backup supply of domestic hot water.

Mega Combi Plus

Again, the Mega Combi Plus comes with all of the same features as the other Combi ranges Mistral have available but the Mega Combi Plus for larger homes such as barn conversions and country homes. Available in outputs of 41-70Kw, these boilers can run up to 35 litres of water per minute.

Sealed System

In this range of System boilers, there’s a condensing and non-condensing boiler available, designed to partner a pre-installed water heating sealed system. The condensing boilers are highly efficient and come with an ErP A rating while the non-condensing boilers have a standard efficiency.

How Much Does A Mistral Boiler Cost?

Mistral have many Combi and System boilers available so depending on the heating and hot water demands of your home the cost could be anywhere between £1800 and £4600 for Combi boilers and £1500 to £3200 for a System boiler. These potential prices don’t include the cost of installation which will vary depending on the engineer carrying out the work. Due to having more moving parts, the System boilers are likely to have higher installation costs attached to them.
