Zero Carbon House

Definately interesting. If I at some point ended up in a house instead of a flat I would love both water-born heating system as well as a heat-pump system like they are using here. The heat-pump system is all the rage here in Norway for anyone that want to reduce their heating bills...

Heat Pump is what we have here and I HATE IT !!!!! Always blows cold heat !!! This stems from the fact that the heat it blows is below body temp but above the temp you desire. So on your skin feels cold. I would think that would be VERY bad in Norway

Additionally it should be noted that below a certain temp the heat pump alone can not keep up with the outside temps. again a very bad thing in Norway I would assume...

Many heat pumps in Norway are of the geo thermal variety which is usually more efficient than the cheaper air-air. Most people also use a bit of electric heating if they've got a big house or have the heat pump connected to their main water tank which again heats their house. We do use radiators and heated floors with warm water in normal residential housing.... I haven't actually lived in a house with a heat pump, but everything I've read says it's a big investment, but very usefull.

Here in the states it is a big investment that needs to be replaced every several years. I would never do it again given the chance to change. And I know there are lots of people that echo my feelings. Someplace with nice weather it works fine but if it is too cold the savings are not really worth it. Perhaps the geothermal ones are better. That would not surprise me given the source of the heat. Here all heat pumps are air to air. Seems they are making these now to be throw away items as everything else seems to be :frown: Mine seem to last 3-4 years and die .... I have tried ALL major brands with the same outcome .

Looking at Enova.no which is the website for our energy-conservation efforts as well as an overview of different technologies and subsidies from the state (the front page is in English as well, click on the UK flag). They say a air-air heat pump lasts for 10-15 years, and removes about 20-60% of the energy needed for heating and warm water.
If you want I can always try to find some of the producers we've got here in Norway, they should last a lot more than 3-4 years. After all the producers MUST supply a 5 year warranty by state-law so 3-4 years would be VERY bad choice for the producers...

I am keeping my fingers crossed that I can eek a couple more years out of the one I have now as it is 3 years old and already on its last legs but I suppose I should do more research BEFORE it dies I hate the fact that I have no other alternative other than a heat pump
