The contractor for the geothermal heating system was Senera Oy.

Terraced house, LoviisaRivitalo

A seaside terraced house switched from oil heating to geothermal heating. Asko Hietalahti, one of the residents, recommends the solution to all small limited liability housing companies. Geothermal heating has reduced the cost of heating by around 60% and eliminated the need for the maintenance work required by oil heating. The geothermal heating system warms up the properties and the service water.

Commercial and industrial property, Vantaa Ylästöntie

A commercial property in Vantaa switched from oil heating to a geothermal heating system. The premises were heated by two old oil vessels that consumed around 60,000 litres of oil per year. One of the oil vessels and the chimney were demolished. The oil vessel was replaced with two geothermal pumps. The geothermal heating system has worked as expected and significantly reduced the cost of heating. The property has more than 3,000 square metres of surface area to be heated.
