All things heat pumps
What are heat pumps exactly, how do they work? Is what you’ve heard about heat pumps true? this is your one stop
shop about all things air source heat pumps.
What is a heat pump?
Heat pumps work very similarly to traditional air conditioners. Heat energy is pumped from one location to another, how this transference occurs can vary, and there are typically two types of Heat Pump: Air Source, and Water Source.
The type of Heat Pump that’s right for you varies on the application but as the name implies an Air source heat pumps gathers latent heat energy from the outside air, and water source heat pump do so from a running water supply. While you might not expect a typically cold air or water supply to be able to heat your home
The Magic of Air Source Heat Pumps
Being able to extract heat energy from the atmosphere at temperatures below Zero, sounds like science fiction, but is indeed science fact.
With the latest technology in environmentally friendly refrigerants such as R32, Heat Pumps can extract air from even the coldest of regions with lower environmental impact than ever.
When the R32 refrigerant passes through an expansion valve, the pressure of the gas is reduced. This reduction in pressure also radically reduces its temperature and can reach temperatures as low as -70C. When this sub-zero gas is exposed to ambient air temperatures even as cold as -25C, there is still a noticeable warming effect to the refrigerant.
The colder a Heat Pump can manipulate the refrigerant, combined with how quickly the warmer outside air can heat it back up again, is the basis for Heat Pump efficiency. As the demand for central heating increases over the winter months, the efficiency of the system will also reduce as it takes more outside air to warm the refrigerant.
Can a heat pump save me money?
Whilst gas and oil options remain a part of the UK Government’s current clean growth strategy, the future is clear that a rapid shift away from fossil fuels is required to meet ever tightening climate targets. During this transition period the prices for carbon-based fuels are likely to continually rise with potentials savings increasing over time.
When replacing some of the older G-Rated LPG boilers, a Heat Pump could save as much as £1,300 according to ‘Which?’ while radically reducing your home’s carbon footprint.

What system is right for me?
Whilst heat pumps can operate all year round, their peak efficiency can only be achieved with a properly designed solution. Two identical installations on the same street or identical houses in two parts of the country can yield radically different levels of efficiency which can severely affect your running costs.
