| How much solar system can I use? |
|
An efficient solar heating system will make the best use of whatever sun is available. To produce heat the sun doesn't have to shine brightly. A parked car, for example, warms up on a cloudy day. Solar collectors can utilize even the smallest amount of solar radiation. Solar collectors from Viessmann are specifically designed for northern climates, and can produce enough solar energy to heat up to 70% of your annual hot water requirements.
