Tube collector

CRK-12

The WOLF CRK-12 vacuum tube collector achieves outstanding solar yields throughout the entire year. This is entirely eco-friendly because solar energy does not generate any carbon dioxide emissions whatsoever.

The perfect solution for rooftop installation

The CRK-12 features high-vacuum insulation that minimises thermal loss from the tubes. It achieves very high yields thanks to optimised efficiency. This makes these collectors ideal for roofs that are oriented in an unfavourable direction or that receive limited sunshine due to shading.

Clean heat all year round


Solar DHW heating and central heating energy

WOLF CRK-12 tube collectors convert sunshine into heat not only during summer but also during spring, autumn and even winter. So this high-performance collector can back up your DHW heating or even your central heating all year long, saving even more CO2.

Lower space requirements

The excellent efficiency level of the CRK-12 means you require fewer solar tube collectors. So they even fit perfectly on small or awkwardly shaped roofs. If there is still no room on your roof, the collectors can alternatively be set up on a garage roof or even positioned free-standing in your garden.

Expandable, modular tube collectors

Simply connect multiple WOLF CRK-12 units together to create more powerful solar heating systems.

Benefits of WOLF solar heating systems

Family at the breakfast table

Environmentally friendly and efficient

Free heat

The sun sends no bills. Solar heat is free once the solar thermal system has been installed.

Easy to retrofit

WOLF solar heating systems are easy to combine with any existing heating system. This makes the system more environmentally friendly and saves fuel.

Increase energy autonomy

The more solar heat you absorb with tube collectors, the more independent you are from gas or oil deliveries. The collectors also have an extremely long service life. WOLF solar heating systems are a robust, extremely durable, tried-and-tested technology. Read more

Various combination options

Environmentally friendly hybrid technology

WOLF solar collectors can be easily combined with a gas heating system, an oil-fired boiler or a heat pump to create an extremely eco-friendly hybrid heating system.

Perfectly coordinated

All WOLF components are perfectly coordinated, work flawlessly as a system and so achieve maximum efficiency.

Simple controls

Centrally operated

As all WOLF system components come from a single manufacturer, you only need a single control unit to operate the entire heating system.

The sun takes priority

Our cutting-edge control units ensure that all available solar heat is always used before activating any other heat generators. In this way, the energy is used sparingly and sensibly. Read more

Controlled via app

The easiest option of all is to control your solar heating system using the smartphone app.
