In Denmark the lack of a better central heating solutions holds a considerable problem for less expensive houses especially, yet in the rest of the world central heating is yet to become standard and a solution to installation of central heating could be very beneficial.
Many houses don’t have central heating, and it’s too expensive to install. (the cost of installment runs up to one fourth of the house value.) Peripheral areas especially. 15% of danish houses don’t have central heating system installed.
We can’t transfer heat and cool from cooling surfaces (radiator or floor heating or aircondition) without central heating or air tunnels
So far we have used central heating through pipes that goes across the building or airducts. Our company have only worked with water or air as medium.
The biggest limitation would be the conservative mindsets of homeowners.
