ground source heat pump
Our pump was replaced recently, even though I'm not that experienced in the area I had some questions.

I wanted this!!! But it din't happen because of three things: 1. The salesman for the new pump an water boiler said it would lower the temperature by a feew degrees maximum, he didn't think it would be musch use. 2. The need to redo ALL of the pipings and radiators in the house. The pipes needs to be isolated, otherwise you'll get moisture on them and evetually mold. Our house is built 1951 and all the pipings are built into the floor and walls, if they hadn't been built into the floors and walls they could have insulated the pipes running along the walls/floors. 3. The cost would have been SEK 25.000 per radiator (~3000 USD), with a lot of radiators the amount of money was too high.

As we have a large south facing roof, we should be able to power the whole thing from solar a PV bank.
The exess heat can also be used to heat up the ground during the summer. We have a drilled hole into the bedrock where we get the heat from, but we also live close to the Baltic sea (6-7 kilometers). In our case it means that we have a lot of ground water flowing towards the sea, so if we heat it up we'll only end up putting heat into the baltic sea. If the ground water had been more stagnant we could have been getting the heat back during winter. In the end we didn't get solar panels, but when we decide to do it everything is prepared for it (it would then only generate heat the water boiler during summer). Another advice from a friends friend ( :rolleyes: ) who sells heating equpment mainly to large corperates was to go for the most basic model without all the bells and whistles. Control the heating system from your mobile? A big no... Aside from being a cool feature how are you going to use it? Heat up the house when going from work? Our house is made from stone, no matter how much we crank the heat up it will take a day before we notice it. If it's a vacation home the it might be a good idea though. The more advanced, the more expensive it will get when replacing/reapiring something.
