The AKVA SOLAR enables utilizing your accumulator to all heating, and increases your annual solar gain. The AKVA SOLAR gives you the most out of solar energy whenever the sun is shining. All models are built so that you can utilize high grade energy from other heating sources to the top as the solar energy will be provided to the lower part for preheat. The lower preheat area will improve the solar gain also when the input is at lower temperatures. You can get high proportions of the heat provided even during the coldest season. We Finns know from the experience that you can get solar energy to the lower part of the accumulator on any bright sunny day – even during winter time. When the solar gain is at the highest, the 100 mm seamless polyurethane
insulation with very low heat losses ensures the solar energy you have gained can be utilized during a long period.
