The Calpak Prisma solar water heater stands out for its energy efficiency and build quality. The new technology Prisma collector and the tank guarantee you a high-performance and durable solar water heater, so you can enjoy every hot bath you take without worries.

For the first time worldwide, the polymer material Colofast by BASF, which is used by the largest car manufacturers for the construction of their car sunroofs, is used in the production of the Prisma solar water heater. This technology offers:

1. Perfect adhesion with glass and metal, making it ideal for their strong connection
2. High torsional rigidity, thus robustness in the overall construction
3. Absolute sealing
4. Perfect finish

It is triple energy, meaning it can operate in three ways: with solar energy, with electric energy, or with hot water from the central heating of the house. This means that inside the water tank there is an electric resistance, as well as a coil through which the hot water from the radiator produced by the central heating boiler circulates. So, on days when there is little sunshine due to cloudiness, you will be able to operate your solar water heater either with electric energy or from the boiler, to always have hot water.

Regular maintenance of the solar water heater optimizes the quality, hygiene, and operational performance, while also saving on energy consumption. For the smooth operation of the solar water heater, regular maintenance by a specialized team is required. The necessary actions during the maintenance of the solar water heater are:

• Checking the level of solar fluids & refilling where necessary.
• Inspecting and repairing the insulation on the local solar pipes.
• Checking and replacing the magnesium anode to prevent the formation of salts inside the solar water heater.
• Inspecting and cleaning the electric resistance.
