How to lower school building energy costs through air source heat pumps

heat pumpIn 2012 the estimated running costs of the average UK school building was just £1,000, offering a potential saving of over £700 when compared to commonly used energy sources such as gas and oil boilers. A typical school building can produce emissions of just 3.4 tonnes, which presents a potential saving of 2.8 tonnes when measured against other methods.Installation of an air source heat pump appliance helps lower these costs, whilst easing your carbon footprint burden.

Its becoming more common for school governors to commission a sustainable and affordable approach to running heating and hot water, and one such approach that has proven to give success is the implementation of an air source heat pump out side the building. Eco Air Boilers can be used to provide heating and hot water for the main assembly halls, classrooms and staff rooms through an underfloor system.

Working of air source heat pumps

These pumps soak up heat from the external air. This absorbed heat can be transferred then to underfloor heating arrangements, heat radiators or lukewarm air convectors as well as hot water in homes or public buildings, such as offices and schools.

This type of pump removes heat from the outer air in just like a fridge utilises heat from its interior. It can extract heat from the atmosphere even at a temperature as down as -15° C. Although it’s true that heat pumps depend on electricity to run, the heat absorbed by them from the air, ground or water is continuously being renewed in a natural way and is therefore kinder to the environment.

How can school building benefit from air source heat pumps?

  • Cut fuel bills, particularly if you are changing standard electric heating
  • Cut carbon production, based on which fuel you are substituting
  • No requirement for fuel deliveries
  • Get your home heated and supply hot water
  • Little requirement for maintenance – they’re known as ‘fit and forget’ tools

Unlike standardised gas and oil boilers, air source heat pumps generate heat at lower temperatures over much longer periods. During the winter it’s advised to leave onto supply a constant stream of heating.

Is an air source heat pump suitable for me?

To recognise if an air source heat pump is right for your school building, there are a few vital questions to consider:

  • Do you have space to fit the appliance? You’ll need a place on your premises where a unit can be fitted to a wall or situated on the ground. An air source heat pump will require space to generate surrounding air; the ideal location is a sunny wall.
  • Is your school building well insulated? Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it’s important that your building is insulated and draught-proofed correctlyin order to get the maximum output from the unit.
  • What form of energy supply are you switching from? The method will be of greater value if it’s taking place of a coal or electricity system.
  • What kind of heating system are you going to use? Air source heat pumps are known to function more effectively with warm air heating or under-floor heating systems than with radiator-based structures, due to needing lower temperatures of water.
  • Are air source heat pumps meant for a new improvement? Consolidating the fitting with existing building work may cut down instillation costs.
