Domestic Boilers

Wiltshire Biomass MCZ Domestic Boiler

In most cases a biomass boiler installation does not need planning permission and it is fairly straightforward to retrofit into an existing building. There are different types of boilers:-

Living area boilers

Living area boilers are designed to go into a living area of your house. These are common in mainland Europe and are typified by design accessories in ceramic or metal facia. If you are renovating or putting the boiler into an existing house then you can make use of an existing chimney which will lower installation costs and save space. If a suitable chimney is not available then you can place the boiler against a wall and use a flue instead of a chimney.

All MCZ boilers have a top loading hopper. The "Suite Hydro", (pictured right), has a 44 litre hopper that would last approximately 2 to 3 days during the peak heating season or up to 2 weeks on a frost setting. The boilers do require simple maintenance on a weekly basis, which includes cleaning the grate and the screen. The amount of ash generated is negligible when compared to a wood burner or open fire and all MCZ boilers operate at efficiencies of 91.5% or better.

MCZ have an excellent website,, which includes all technical specifications and cosmetic finishes. Their “hydro†ranges are MCS accredited and will therefore be eligible for any government incentives and subsidies. For more on biomass boilers in Wiltshire and surrounding areas, please get in touch.

Utility Boilers and Fuel stores

Other biomass boilers are made specifically for boiler rooms. Less elegant than the living room boilers they can come with enhancements such as automated cleaning and large fuel stores – meaning that you can just leave them to get on with the job for months at a time! The pellet market is advanced in Austria and many of the leading makes of boiler come from there. We work with Windhager & Oekofen who are both MCS accredited. These manufacturers pride themselves on reliability and "Austrian engineering". They do have history on their side and a well established market in Austria and Germany to call on. These systems are promoted as "premium" and they do take longer to install as there is more for the installer to do. Typically we find ourselves working on these in non standard and larger houses.

These biomass boilers can heat larger spaces, for example the Windhager range starts at 11kW and goes right up to 60kW, with 180kW being possible by installing 3 boilers in parallel! Windhager have an excellent and informative website which can be found at Most of the bigger boilers also come with the option of separate fuel stores with automated fuel feeding into the boiler, meaning that a boiler could be left untouched for months at a time.
Extra costs are involved where there is extra work, such as: multiple boilers, small building works to house fuel stores, complex pipe work to multiple zones and different heating types present, (e.g. under floor and radiators).
