Logs, pellets, chip or waste wood — from a single cottage to a whole estate.
Biomass heating systems
Biomass heating systems come in many forms, burning logs, pellets, wood chips or even waste wood. Modern biomass boilers are highly efficient and environmentally responsible, producing very low emissions while using a fuel that is low‑carbon when sustainably sourced.
They are available from around 7kW up to large commercial and industrial units, which makes them suitable for almost any property — a single home, a rural estate, offices, workshops, industrial buildings. It is also common to heat several properties from one boiler using district heating.
Biomass is an excellent replacement for oil and gas, with no need to change existing heat emitters. It is particularly popular in rural areas where mains gas is unavailable, oil prices fluctuate, and direct electric heating is prohibitively expensive.
The four types
Batch boilers
Gasification boilers that burn logs or briquettes and charge a large accumulator tank. The stored heat then serves industrial processes, space heating or hot water.
Often chosen by customers with free or low‑cost firewood. They do ask something of you: lighting a fire once or twice a day in winter, once every four to seven days in summer, depending on demand and tank size.
We supply log gasification boilers from 10kW to 100kW, and larger outputs by running several in parallel — homes, workshops, estates and small commercial sites.
Fully automated
Pellets are compressed sawdust, dried to a very low moisture content and supplied in 10kg bags or blown into a silo by tanker. Bulk is usually the most economical. Quality matters: poor pellets raise breakdown risk and deliver less energy.
They ignite, modulate and shut down without you. Most models include a hopper; larger systems use silos or storage rooms feeding the boiler automatically. In daily use they behave much like a modern oil or gas boiler.
We install from 7kW upwards, with no upper limit.
Why we install Hargassner
We currently install only Hargassner biomass boilers. The reason is simple: their engineering quality is unmatched.
Their boilers use a ceramic combustion core, which cuts emissions by holding extremely high combustion temperatures. That super‑heated chamber burns off more particulates, improves efficiency, and makes ignition of pellets, chips and other fuels cleaner and more reliable.
Hargassner also make their own fuel‑delivery systems — augers, suction systems, agitators and silos — so the fuel handling is designed alongside the boiler rather than bolted to it.
And they can link a log boiler and a pellet boiler into one system: free or low‑cost logs when you have them, fully automated pellets when you want the convenience.
District heating
We are heavily involved in district heating, where several homes, apartments or commercial buildings are supplied from a single biomass boiler.
A strong option for estates, rural developments, farms, commercial yards and multi‑unit properties.
Hot‑water storage
As well as installing biomass boilers, we supply and fit a full range of thermal stores and hot‑water storage systems.
These tanks are integral to the correct operation of many biomass systems, ensuring stable heat delivery, efficient boiler cycling and reliable hot water — and a log boiler in particular is only as good as the store it charges.
