GP Pellet Boilers

840kW GP Pellet Boilers – Bilston

The site in Bilston totals 970kW keeping it under the 1mW and comprises of 2 x 420kW GP Pellet Boilers and 1 x 130kW Gasification Boiler.


The client needed a system that would maintain the warehouse at an effective temperature that would prevent the Steel from rusting.


The bulk of the heat is produced by the two 420kW Pellet boilers, but this is supplemented by the burning of Virgin Waste Pallet Wood that gets supplied with each delivery of raw steel. By registering on the BSL as a Self Supplier the client is able to burn his own wood. The two Pellet boilers are connected to a 20 ton Silo supplied by Biomass Silo Systems and connected to a day hopper that is fed by a Vacuum unit. The vacuum system has a separate container that filters out all the unwanted dust that is created during transport and from the blown delivery. The GP Pellet boilers have no trouble burning these Industrial Grade Pellets, which have up to 6% fines.

The accumulated heat is stored within a 25,000 litre vessel which is then circulated around the warehouse. The heat is dissipated via 18 x 75kW Proton Fan Coil Heaters. These are extremely quiet and robust heaters that have three speed modes; low, medium and high. This is very useful when trying to achieve the correct flow rate through the system.

This installation was carried out and commissioned by JD Energy Services Ltd of Wales.

Pelleburn domestic installation

Bridgnorth, Shropshire

A 120kW Pelleburn domestic installation in a beautiful property in the Shropshire countryside that was running on oil to heat the property. The owners wanted to drastically reduce their CO2 emissions and switch to a more sustainable source.


The old oil boilers were in the basement of the main property, which was also prone to flooding due to being below the water table. A new site had to be found to house the Biomass Boilers so that they wouldn’t interfere with the original building and be above any water line. Being a domestic property with a 120kW Thermal Heat demand, the correct boilers had to be selected to meet this requirement.

Heating a property of this size on the current fuel is unsustainable. An alternative was required.

John Nicholls, Client


The decision was made to create a purpose built unit that would enclose not only the three BURNiT 40kW PelleBurn boilers but also the 2000 Litre Sunsystem Buffer Tank and 4 Tonne Silo. The three boilers were connected to the buffer tank in such a way that they would only come on when there was a drop in temperature within the tank. The greater the drop, the more boilers would operate. This meant that there was always enough hot water in the tank to meet demand.

80kW Ekogren Multifuel Boiler

80kW EkoGren Multifuel

Chesterton Hall is a beautiful Grade 2 listed 8 bedroom detached house in the idyllic Shropshire Countryside. Despite the beauty of the property, The EPC certificate showed that the house had a very low energy efficiency rating, which is expected for a house of this period. So the property not only needed more energy efficient measures in place, but also a new heating system that could cope with the demands of such a house.


As with all old listed properties decisions have to be carefully considered when coming to pipework and not interfering with the fabric of the original building. Chesterton Hall was off Gas, so a new heating system that would meet the required constant demand and efficiency levels was required. For this an 80kW EkoGren Pellet boiler was chosen.

We new we had to replace our existing heating system and always thought of Biomass being in a rural area. No matter what the weather is outside the heating is always the same.

An area was created in the large garage adjacent to the house where the 80kW EkoGren Multifuel boiler, 2000 Litre Buffer Tank and Wood Pellet Silo was sited. The Buffer Tank heated the space heating and connected to a plate heat exchanger that provided Domestic Hot Water on demand. So as not to interfere with the original building, 20 metres of district heating pipework was laid from the garage across the drive to the area under the house where the old oil boiler was. This allowed for the installation company JD Energy Services to connect to the existing system without having to make any alterations to the property.
