A heat pump is a modern device that is used to heat buildings and may also be able to heat domestic water. What's more, it can also cool rooms in summer. Check out the TOP 5 best ground heat pumps.
A ground heat pump uses energy from the ground for heating. It is efficient, but requires a lot of space for installation. The heat generated in the lower heat source is transported to the upper source and distributed throughout the building. As a ground source, you can choose a horizontal or vertical collector. The horizontal collector is installed at a depth of approx. 1.5 m below the ground frost zone, but this requires a large plot area. However, a vertical collector requires drilling to a depth of up to 100 m.

What to choose: ground or air heat pump?
An air pump is certainly cheaper and easier to install, but it is a ground source heat pump is the most efficient and stable. At low outdoor temperatures, the air pump may use more energy to operate, thus increasing operating costs.
The air heat pump is recommended for investors who do not have a large plot of land. Investment and installation costs are lower than in the case of a ground pump.
