WORLD’S MOST REVOLUTIONARY SOLAR WATER HEATER
Hot water has never been so affordable, beautiful and innovative.
COSTLESS HOT WATER
From the #1 solar water heater
SUNPAD provides sustainably treated hot water at the best price and is the perfect symbiosis of innovation, design and usability. We contribute to significantly influencing the energy habits of the worldwide population through SUNPAD. And to begin a new approach today as part of tomorrow‘s energy system.
With our intelligent energy solution for your individual needs we can reduce
- the Co2 emission by one SUNPAD which corresponds to 100 huge planted trees.
- your heat energy costs by up to 80% depending on your climatic environment
SUNPAD is a unique and completely new solar system. By integrating the heat carrier tank into the insulation, which includes all supporting components at the same time, we have created the most compact solar system available on the the market.
Due to the small number of components, the system is virtually maintenance-free. The heart of the system is the heat storage tank. It contains 150 liters of water. The tank is manufactured using the latest laser welding technology.
The special solar coating on the surface of the tank causes the heat transfer fluid in the tank to be heated when exposed to the sunlight. The incident solar energy is released directly without line losses to the water. This means the system provides 150 liters of heat transfer fluid during the day up to 85 degrees celsius (depending on climate zone and local environment).
This tank also hosts the precisely dimensioned (19 m long) heat exchanger which carries the actual potable water.
Connected to the house water pipe, the tank is fl owed through with the tap water. If water is tapped, it will heat up as it fl ows through the heat exchanger and hot water will be available.
With the downstream mixing valve, the water will be mixed down to the desired temperature. Depending on the enviroment and temperature of the system, up to 380 liters of water with 40 degrees celsius will be available.
To maintain the temperature in the tank, it is encased with up to 50 mm thick insulation of high-quality extended polypropylene foam (EPP). This insulation also takes over the holding function for the highly transparent and UV resistant cover insulation and the solar safety glass.
The SUNPAD revolutionary solar water heater ticks all the boxes when it comes to its performance in our harsh climate. This definitely allowed the confidence and ambition to drive the SUNPAD experience forward to all our valuable clients.
