Power factor is a measure of how effectively electrical power is being used by a system. It is defined as the ratio of real power (measured in kilowatts, kW) to apparent power (measured in kilovolt-amperes, kVA). Mathematically, it is expressed as:

Pumps are essential components in HVAC (Heating, Ventilation, and Air Conditioning) systems, playing a crucial role in maintaining optimal temperature levels and ensuring efficient operation. These pumps are responsible for circulating the system fluid, facilitating the transfer of heat and enabling the cooling process.  By continuously moving the fluid, pumps help transfer heat from the indoor environment to the outside, thereby maintaining comfortable temperatures indoors.

Replacing ageing school boiler plant can be daunting. Heating systems can only feasibly be replaced when the site does not require heating or a continuous water supply. In addition, projects often have to be squeezed into the summer vacation to avoid traffic, disruption and the presence of contractors during term-time. This small window of opportunity can create inconvenience and cost. As summer is the busiest time for the building industry it can be difficult to guarantee availability of contractors for the designated weeks. Many independent schools have additional challenges relating to the architectural heritage of their school buildings. Access can be problematic and something as basic as the size of doorways can present problems when removing the old boiler or positioning its replacement.
