Mistral oil-fired combi boilers

There are lots of reasons combi boilers are so popular with homeowners. They are compact, easy to install and easy to service. They can also provide hot water on demand, which means no waiting around for water to heat up.

Mistral has four combi boilers to choose from: the Combi Standard, Mega Combi Standard, Combi Plus and Mega Combi Plus. Within these boiler ranges you have the option of choosing condensing and non-condensing and internal and external models.

These boilers have a high quality casing, multi directional flue outlet and pre-punched pipe access points for easy installation.

Mistral oil-fired regular boilers

Regular boilers, also referred to as traditional boilers or heat only boilers, need to be installed with a cold water storage tank and a hot water cylinder. The storage tank supplies cold water to the boiler which it heats up and transfers to the cylinder to stay warm until it is needed.

One of the main benefits of a regular boiler is that it can supply high volumes of hot water to multiple bathrooms or outlets at the same time. A regular boiler is also a great choice for properties in areas with low water pressure.

Mistral’s selection of regular boilers are available in output sizes ranging from 20kW to 70kW making them a great choice for small houses to large properties with several bedrooms and bathrooms.

Mistral manufactures condensing and non-condensing models as well as internal and external regular boilers.

Mistral oil-fired system boilers

A system boiler is ideal for homes that have more than one bathroom or have a high demand for hot water. It works in a similar way to a regular boiler but connects directly to the mains water. This eliminates the need for a cold water storage tank but still means that you can deliver hot water to multiple outlets at the same time from the cylinder without losing pressure.

Mistral system boilers are available in a range of outputs from 20kW to 41kW.

These boilers are equipped with a:

  • pressure gauge
  • circulating pump
  • 12 litre expansion vessel
  • automatic air vent
