A heat pump is a device that uses a small amount of energy to move heat from one location to another. Heat pumps are typically used to pull heat out of the air, ground, rivers and other low grade heat sources to heat a commercial building or provide heat into community or district heating networks.
Vital Energi offers ”ground and water source heat pumps” and “air source” heat pumps for district and community heating schemes and commercial properties.
There are two main classifications of heat pump:
Low Temperature Heat Pumps (LTHP) are better suited for use with low temperature building heating systems such as under floor heating, air heating and fan assisted low temperature radiators.
High Temperature Heat Pump (HTHP) systems, dependent on the technology, can offer water temperature up to 90oC. These systems can be utilised for community and district heating schemes where there is a suitable heat source or as an alternative to oil or biomass where the system is off the gas grid.
GSHPs and ASHPs can lower energy bills for businesses and are eligible for the government’s Renewable Heat Incentive (RHI) and therefore generate a return on capital investment.
On average, ASHPs are easier and lower cost to install, while GSHPs are more efficient.
ASHPs and GSHPs are considered “low carbon” technologies and offer similar benefits when it comes to their environmental performance. When comparing HPs with conventional fossil fuelled heating plant both can result in reduced global CO₂and local NOx emissions. They don’t require chimneys and unlike, wood, oil and LPG, fuel deliveries or the additional petrol or diesel emissions this entails.
Heat pumps are extremely efficient and take the majority of their energy from the environment. They can also contribute towards successfully gaining planning permission and meeting the Code for Sustainable Homes.
