Our patent is related to the fact that it is the only thermosiphon kit that works with the panels in series (Kit 280 WKR). This means that the temperature in the heating circuit (antifreeze) is almost twice as high, thus increasing the heating speed (the higher the water temperature in the tanks, the greater the difference to other systems).

Having twice the temperature in the heating circuit means that it needs half the solar radiation to start heating.

Two interior tanks in series means that it is much harder for the cold water entering one tank to cool the hot water leaving the other tank.

Tanks are made from the best stainless steel for drinking water (AISI 316) with a thickness of 2.5 mm, so they can easily last at least 20 years: because of this, they are guaranteed for 10 years.

The entire exterior of the tank is made of 0.8 mm thick stainless steel, which allows its aesthetic to be maintained over many years.

the material used in the tanks means that the equipment only needs maintenance every 7 years.

Feet rise vertically with ease, allowing the equipment to be easily oriented in a manner that provides greater efficiency.
