Small interior heat pumps
 

Small heat pumps that do not require external units, also known as ductless mini-split heat pumps, are gaining popularity in the UK as a new and innovative way to heat and cool homes. These pumps are compact and can be installed indoors without needing an outdoor unit. They offer several advantages and disadvantages compared to traditional heat pumps, and certain factors limit their applicability.

Interior Heat pumps

One of the major advantages of small heat pumps is their energy efficiency. According to the UK Energy Saving Trust, ductless mini-split heat pumps can be up to 20% more efficient than traditional HVAC systems, resulting in significant energy savings over time. This is because they do not require ductwork, which can result in significant energy losses due to leaks and poor insulation.

 

Another advantage of small heat pumps is their ability to provide zoned heating and cooling. This means that different rooms or areas of a home can be heated or cooled independently, resulting in greater comfort and energy savings. This is particularly advantageous for homes with uneven heating and cooling needs.

 

However, they are a lot less powerful than traditional heat pumps, which can limit their ability to heat and cool larger spaces. According to a UK Department for Business, Energy & Industrial Strategy study, ductless mini-split heat pumps are most effective in homes with heating and cooling loads of up to 10kW.
