Many cabin owners like to keep space heating on at a minimum to prevent freezing of pipes and also to keep moist and odour away. SolTech Flex is a solar collector specifically designed for second homes, cottages and other spaces where there is a need for minimum space heating (maintenance heating) and ventilation. SolTech Flex is easily installed on the outer wall in the fall and removed in spring when there is no longer any need for minimum heating.
SolTech Flex consists of an inflatable frame with two removable covers. The covers, together with the fixed absorbation screen, create two separate air spaces where the front acts as insulation and the back is used to heat the circulated indoor air. The front screen is transparent. The sun shines on the absorbing black screen where the solar energy is converted into heat and heats the air in the air gap behind it.
Two holes, inlet and outlet, through the outer wall of the house connect the SolTech Flex with the indoor air of the house.
