Four ways to get energy

Ground source – horizontal loop

Watch our ground source/horizontal loop video

The horizontal ground loop collects solar energy stored close to the surface. If the bedrock is too deep, or if you do not wish to drill for other reasons, this alternative is a good choice. The loop is buried around one meter beneath the surface of the land and energy is extracted from the ground. The length of the loop depends on the house, the size of the heat pump and local ground conditions.

Advantages:

  • Lower installation cost compared with vertical ground loop
  • Can also be used to extract heat from lakes
  • Ground loop maintains consistent temperature throughout the year
  • Cooling is possible

Ground source – vertical loop

The vertical ground loop collects solar energy stored in bedrock. A hole is drilled into the bedrock and a pipe is laid to a depth of between 100 and 200 meters. The exact depth depends on the house, the size of heat pump and the surrounding conditions.

Advantages:

  • A large plot is not necessary
  • Small impact on the plot
  • Cooling is possible

Air source

Watch our air source video:

With an air source heat pump, there is no need to dig or drill. Instead, you take the energy straight from the surrounding air. To obtain a complete system that covers all your heating requirements, including hot water, you need an air source heat pump. In comparison, an air-to-air heat pump is only capable of supplying heating, not hot water.
Advantages:

  • Lower investment cost
  • No impact on the ground
  • No large plot needed

Groundwater source

A groundwater heat pump collects energy from the groundwater. The water is pumped up from a water borehole to a heat exchanger, where the energy is recovered. The water is then discharged back through another well. This solution can be the right alternative when groundwater is readily available.

Advantages:

  • High and even temperature in the groundwater, all year round
  • Cooling is possible

Exhaust air

The energy from the warm indoor air is reused before it leaves the building through the ventilation system. Energy can be recovered by a special heat recovery unit, which increases brine temperature and heat pump performance.

It works for smaller houses as well as for larger buildings. In commercial properties where ventilation systems are in constant operation, exhaust air can provide as much as 50% of the building’s energy requirements. This system works perfectly with inverter-driven heat pumps where the heat pump can automatically adapt to any desired temperature in the exhaust air.

Advantages:

  • Lower running cost and simpler installation (fewer boreholes and volume tanks)
  • Improved seasonal performance
  • Easy to combine with existing heating and ventilation system
