Toni Oksman from Vantaa has lived for a year with his wife and children in their 2016-built single-family home. Due to its location, ground source heat was the only viable heating alternative for the house, as neither district or direct electric heating were available for the family’s area of residence. Oksman’s prefabricated house from Kastelli came ready with Gebwell’s Qi ground source heat pump.
He admits having some initial doubts about the heat pumps.
“At first, I was nervous to see how things would go. I had heard stories of circulation pumps malfunctioning in some devices. It seems, however, that in such cases the pumps must have been from other manufacturers,” Oksman recounts.
