Heat pumps do not generate heat, they move it.

The Different Types of Heat Pumps.

If you’re considering replacing your current heating and hot water system with a renewable alternative, it’s essential to be aware that this can be a significant investment. In many cases, it involves a partial or complete system upgrade, as heat emitters and pipework often (though not always) need to be updated to achieve optimal flow rates.

To determine if a heat pump is suitable for your property, you can consult the UK government’s suitability guide. The MCS best practice is here. or use our own quick suitability checker.

ASHP: Air Source Heat Pumps.

While an air source heat pump may look like a simple box sitting outside your home, it contains several components that work together to capture heat from the air and transfer it into your heating system.

There are two main types of air source heat pump available in the UK:

  • Monobloc heat pumps
  • Split (sometimes called twin-unit) heat pumps

Both operate using the same principles, but the arrangement of their components differs. More information on ASHP here

WSHP: Water Source Heat Pumps

A Water Source Heat Pump (WSHP) works in a very similar way to an air source heat pump, but instead of extracting heat from the air, it extracts heat from a body of water.
You would usually need space for a plant room (pump and water heating equipement) but im guessing you will have if you are lucky enough to have a lake!

Potential heat sources include:

  • Lakes
  • Rivers
  • Streams
  • Canals
  • Boreholes

Water can be an excellent source of renewable energy because temperatures tend to remain more stable throughout the year than outdoor air. This can allow water source heat pumps to operate at high levels of efficiency, particularly during colder months.

GSHP: Ground Source Heat Pump

A Ground Source Heat Pump (GSHP) works in a very similar way to an water source heat pump, but instead of extracting heat from the water, it extracts heat from ground. You will again need space for the plant (pump and water heating equipement) and the land to install coils or make a large borehole.

Hybrid System

A hybrid is another option to consider, where a fossil fuel-powered boiler (like gas) works alongside a heat pump. This setup can help meet increased heating demands during the colder winter months while still reducing overall reliance on non-renewable energy sources
