Heat Production

Fuel efficient solution to suit individual business needs


Biomass Boilers and GSHP's

With increased focus on fuel costs, sustainability and revised RHI income streams, businesses across all sectors increasingly strive to optimise their energy mix. Centralised heating plants using a variety of low cost fuels can provide a good return on investment and fuel cost stability.

In addition to our virgin biomass systems (straw, pellet, wood chip),we also supply designs that incorporate litter burning, CHP, heat recovery, heat pumps and underfloor heating. With a wide range of options and modelling available, it can be complex knowing which system to choose in the design stage. Contact our advisors to find out the best solution for you.

Biomass Boilers

To date over 500 poultry houses installed with draperGROUP renewable heating systems and equipment.

115,000 kW of biomass boilers installed using all renewable fuel types, saving over 150,000,000 kW/h of fossil fuel usage every year.

Indirect Heating and Cooling using Ground Source Heat Pumps

A ground source heat pump (GSHP) extracts solar energy stored in the ground or water sources and converts this to a higher temperature for use in a building’s heating distribution system.

A heat pump produces up to three or four times more energy than it consumes. So for every 1kWh of energy your heat pump uses to power itself, you will get typically 3 or 4 kWh of energy to heat your building. The efficiency is referred to as COP (coefficient of performance). The higher the COP, the less the electric bill to power the heat pump.

Typical average ground or ground water temperatures are between 8 and 120C. The heat pump upgrades this low-grade energy via the refrigeration cycle using refrigerant gasses in the system which boil at low temperatures. The phase change from liquid to gas and back again within the closed refrigeration cycle allows energy to be harvested and upgraded. The temperature difference between the ground/water collector temperature and the final flow temperature into the building dictates the COP. Therefore, a typical flow temperature into the building between 45 and 50 0C is common, with higher temperatures being tolerated for short periods at the expense of COP.

GSHP's are fully integrated within our ventilation systems.
