The different methods for extracting energy using heat pumps are described
in a separate section. This is a brief summary.
Rock heat is the most common and gives a very stable heat source
One or several holes are drilled in the rock. One advantage to this method is that it has minimal impact on your garden.
Ground heating means that a long hose is buried in a loop about a metre below ground on your property
This method avoids drilling. On the other hand a large part of your property, which also has to be quite large, will need to be dug up. A rule of thumb is that the cost of digging is about half the cost of drilling for rock heat.
For lake heat your house needs to be close to a lake
A long hose is anchored on the bottom of the lake using weights. You don’t need to drill deep holes. As a guideline the cost of anchoring the hose is about half the cost of drilling for rock heat.
Air heating is the heat extraction method that has the most simple installation because it does not require drilling or hoses being laid
When it is really cold outside this solution may reduce in efficiency . |
