Q&A: What is the cost of running a heat pump in Ireland's cold weather?

A Daikin wall-mounted heat pump. Heat pumps do not perform in the same way as oil or gas boilers. They are not reactive and need settings to match their 24/7 service in winter.

What does it really cost to run an air-source heat pump in cold weather? I see alarming reports from users on social media.
