Church Stretton, Shropshire, HDG Euro 50 kW Installation

Domestic wood biomass


A five bedroom Georgian country house set in four acres, located in Shropshire, has recently upgraded from expensive oil heating to a carbon neutral Euroheat HDG biomass boiler, installed by the Efficient Energy Centre. The new system comprises of a Navora 30kW log boiler, with 2,000 litre accumulator.


Part-funded by the Renewable Heat Premium Payment (RHPP) stage two, with a grant of £2,000, the system should benefit from the domestic Renewable Heat Incentive (RHI) when it is hopefully launched next spring – the owners are already enjoying considerable savings on their fuel bills.


Step 1: The first step in a biomass installation is laying the underground pipework, once this has been completed concrete foundations are built for the boiler house where the equipment is stored.

Storing logs in a covered but well-ventilated area is essential. For a biomass boiler to work at its’ optimum, moisture content in the fuel should be 25% or less. Logs should be split, to increase bark free surface area, and left to dry for 18 months.




Step 2: Once the biomass heating system has a ‘home’ it needs to be positioned inside the boiler room before connecting.

Accumulators are required to store hot water, allowing the boiler to run most efficiently; at full steam, switching off when the accumulator is full. The accumulator then keeps this water warm, providing on-demand heating and hot water for building occupants.

Step 3: Once all the equipment has been positioned and installed, the flue is put up and the heating system commissioned.

Step 4: Following the commissioning of the boiler, work can start inside the house to connect the biomass system to existing pipework (in the case of a retrofit project).
