Integrating a Biomass Boiler with existing systems
As with any other type of boiler, it is quite possible and normal to integrate a new biomass boiler into a property’s existing heating system by connecting to radiators, water tanks and under floor heating. The boiler can either be controlled using your existing control panel, or a new one can be installed.
All biomass systems use a flue (like a duct or chimney) to release the gases produced during combustion. Flues can in many cases be placed inside your property’s existing chimney, though minor work may be needed in order to line it. Alternatively, the flue can be installed outside, although this may require planning permission.
If your property does not have an existing wet heating system or if it does have one but it is in need of being replaced, it may be very costly to install this and a biomass boiler may not be suitable. If this is the case, it may be better to consider an air-to-air heat pump.
Another necessary consideration is the availability of space for the boiler, fuel store, flue and other parts in and around the property. Given that biomass boilers tend to be much larger than conventional fossil fuel boilers, it may be necessary to either construct a separate boiler house or extend the existing building.
The suitability of biomass systems for each property depends on individual factors, however, and it is always a good idea to discuss your plans with a qualified installer and/or heating engineer before making any final decisions.
It is also possible to install a biomass system as backup in order to supplement your existing boiler, though this will not offer such a large reduction in terms of carbon footprint.
