How does it work?

Hot water free from the sun


A Solahart solar hot water system uses the sun’s natural energy to heat water. There are three main types of water heater, each using different technologies to harvest the sun’s energy.

From roof mounted systems to heat pumps, which don’t use collector panels to extract the energy from the sun, these technologies are state of the art and all are designed to provide luxurious hot water with minimum energy use and impact on the environment.
