Re your article (‘You can walk around in a T-shirt’: how Norway brought heat pumps in from the cold, 23 November), Norwegian homes are built to some of the highest standards in terms of their thermal performance, and have been for many years. Low heat-loss houses are ideally suited to the use of heat pumps – as well as other low‑energy/passive solutions – and so it should not be a surprise that the Norwegians have taken to the technology.
Unfortunately, the UK has not been so far-sighted in terms of energy consumption, and so we have housing stock whose thermal performance is poor, meaning that adopting heat pump technology becomes a real challenge.
