Comparing Heat Pumps

It can be much harder to compare heat pumps than boilers.

There are 3 things that matter;

  • The ambient temperature
  • The flow temperature
  • The return temperature

The actual KW of heat generated by a heat pump is a product of these and the refrigerant used. Different manufacturers use different design temperatures. At Clade we believe in being up front and honest, so all our heat pumps do FULL duty at -5°C ambient.

Here’s an example

What does that mean for the £/KW between us and our competition?

  • At nameplate rating we’re slightly more expensive but,
  • At -5°C we’re 19% cheaper per KW

Although the competitor appears cheaper initially, when it actually counts and heat is required the competitor is far more expensive per KW.

Be careful when comparing heat pumps!
