A basic aerial system is required for almost all properties and in its simplest form will consist of an aerial mounted externally high up on the building, with a down lead to an outlet plate near the television.
An air source heat pump (ASHP) is able to extract heat from the external air and by using the principles of vapour compression refrigeration, transmit this heat for use inside a building. It basically functions the same way as your fridge, but in reverse.
The basic description of a boiler is that it is a ‘closed vessel in which water or other fluid is heated in a controlled manner’. The heated or vaporized fluid leaves the boiler for use in various processes, including heating applications, boiler-based power generation, washing and meal preparation.
Ground Source Heat Pumps (GSHP), use the principles of heat pump technology to elevate the temperature of water circulated through pipes buried in the ground, up to a usable temperature for space heating. Typically, a ground source heat pump system can generate low temperature hot water up to 55˚C. However, to achieve a high coefficient of performance (COP) an output temperature of only 35˚C is the norm. This lower temperature is ideal when used in conjunction with underfloor heating systems.
