How to Determine if My Heat Pump is Oversized (No Heat Meter) Checking

Applications

I’m trying to figure out if my heat pump is oversized. I know that frequent cycling is one indicator, but I’m wondering if there are any other methods or solutions I can use to determine this without a heat meter.

Any suggestions or advice would be greatly appreciated!

Hello @Alex9

A couple of questions:

  • What is the make, model and capacity of your heat pump?
  • What is the annual electricity consumption?
  • What was your previous gas/oil etc consumption?
  • What is the floor area and fabric of your house? Do you have the heat loss calculation that was used to assess the heat loss of the house?
