Heat Pump Running Costs Explained

Running costs come from the whole system

A heat pump does not create a running cost in isolation. The house, the controls, the emitters, the hot water demand and the flow temperatures all affect what the final numbers look like.

That is why two homes with the same brand of heat pump can end up with very different outcomes.

What usually keeps the numbers sensible

Good heat loss work, realistic emitter sizing, steady controls and sensible commissioning are what tend to produce calmer, more efficient systems.

If the system is oversized, badly set up or pushed to run too hot, the running costs can look worse than they should.

• Heat loss and system sizing
• Emitter performance at lower temperatures
• Controls strategy and commissioning quality
