Yeah, I searched the name too and came to the conclusion that the company makes heat pumps of some sort.
In Sweden they have categorized (as I mentioned) the heating system using heat pumps to, bedrock, ground, air to air, air to water and lake systems.
Bed rock you drill down and sink the collector tubes into the rock. Heat pump extract the heat and warm up a tank of water.
Ground, you snake out a long loop of collector hose a few feet under the ground (requires a fairly large field that is not used).
Air to air, which is pretty much like the cheap A/C boxes we can buy here and mount to the wall and it takes the outside air and extract the heat and blows it into the house.
Air to water is also using outside air but it extract the heat and warm up a tank of water and send it into the existing grid of pipes and radiators.
Lake is if you have a lake or pond and can sink a loop of collector hose into the bottom and then it is the same heat pump as in bed rock or ground.
Bed rock is by far the most expensive to install due to the drilling but also the most stable source of heat.
Air to air is the least expensive to install but lack in stability due to the out door temp which can vary and you don't have the backup of having a water tank that could be heated by electric rods if it gets too cold.
It is several companies selling heat pumps in Sweden. Thermia, Nibe, CTC are a few of them.
