In reply to Daniel Albert. Hi Daniel, That is what I wanted to know when I started searching. We have a gas system, radiators on 15mm pipes. But when we lived in Cyprus we had inverter Aircon units, they worked well in the winter, but never really hits freezing on the coastal plain. From what you just said you have the split systems, like aircon and no radiators? Many Thanks

How many air to air heat pumps compared to how many ground to air (geothermal), which brands of pump are commonly used in Norway… Thanks!!

This article’s somewhat misleading. Sweden has invested considerably more in efficient ground-source heat pumps than Norway. Most heat pumps installed in Norway in recent years have been cheaper, less efficient air-source heat pumps, typically used in reverse mode, as air-con units during hot periods during the summer. So Norway’s brag here is – yet again – cheap misinformation. Log burners are much more commonly used in Norway, which is why the air quality in Norway during the winter months is so poor.

I had an air to water Heat Pump installed February 2022 there were installation problems and insulation problems on the pipework. The company went into liquidation within 3 months then filed for bankruptcy within a year. I had an insurance backed guarantee (who knew nothing about engineering or heat pumps). At the third attempt they got someone to review and correct the work, this was done this summer, I did not use my central heating for a few weeks then when I switched it on it did not work. I am told that their is a blockage (on the pipework) for 3 weeks the Insurance company and contractor have been investigating and my heating comes from a “Fan heater”

In reply to Mike Powell. Of course it’s all relative to the building square meterage , but we have been quoted £34,000GBP for 486 square metres . That I believe incudes the ugly panel radiators , tank etc , it’s a complete refurb so should be easier , financially in terms of a saving it’s a non starter . However my concern though is will it do the job ?

Sounds great but I was told you needed perfect insulation for it to work

Our experience with a 1970s Air/Air heat pump in Texas was that it worked fine for cooling the house, but the outside condenser froze up as a block of ice when the OAT was below 40 F. In 2011 we built a 3300 sqft (300 sq me) well insulated house with a 5 ton ground source heat pump. The electric power required was about 60% of a conventional AC, and in the winter, it extracted heat from the ground that was put there in the summer. The ground source was 300 foot boreholes with polyethylene 2 inch pipes, in a bank of five, 25 feet apart. In Norway, drilling such ground source wells would be difficult because of the underlying granite.

Any thoughts on the costs/efficiencies for the UK in 2022?

We have a Victorian house with a relatively modern extension at the back (2001 ish). Quotes for installation are coming in at just in at just under £7,000, but our calculations make running costs similar to gas. We have also been told we would need to block up our two Victorian fireplaces.

Such mixed reviews depending on who you speak to. Grateful for any thoughts.

I don’t know where you got those prices. We installed a heat pump which cost £1200 and the electrics and plumbing were done in a few hours by our usual artisans. It’s nothing complex.
