Solar thermal systems are the perfect choice for DHW heating and central heating backup. By harnessing freely available solar energy, you can save on the use of fossil fuels. What's more, investments in solar thermal energy pay off in just a few years.
Our powerful solar flat-plate collectors can save on average up to 60 percent of the energy required each year for DHW heating. Combined with a condensing boiler, solar energy enables you to cut your total energy consumption by more than a third.
A powerful and attractive flat-plate collector, the perfect addition to any heating system. With an individual absorber area of 2.3 m², Vitosol 100-FM solar collectors can be effectively matched to any energy demand, repla...

"Nothing is ever that good that it cannot be improved". This guiding principle is embedded in our corporate values. We can rightfully claim to be a leader in quality and technology in our sector and, as such, constantly aim to set new standards. This especially applies to our product range, consistently geared towards reducing the use of fossil fuels significantly and gradually replacing them with renewable energies. Ever-rising energy costs mean that there is an urgent need to reduce fossil fuel consumption as soon as possible.
Our solar colectors are designed to be seamlessly integrated with Viessmann Condensing boiler technology for an optimum result. Taking current energy prices into account, it is the most cost-efficient alternative. Viessmann oil and gas condensing boilers convert up to 98 percent of the fuel oil or gas that they use into heat. Combining them with highly efficient Viessmann solar collectors enables you to save up to 35 percent on heating costs if you use solar collectors for both water heating and backup heating. Energy consumption can be reduced by up to 60 percent on water heating alone.
By installing solar collectors, you are demonstrating your commitment to protecting the environment, by sustainably lowering CO2 emissions. By choosing Viessmann technology you are opting for a more energy secure future and a system in which all components interact optimally.
Viessmann supplies you with all the technology you need from a single source.
For the complete solar thermal range, Viessmann offers optimally matching system technology from a single source. All components work together perfectly. This gives you the guarantee of outstanding efficiency and high operational reliability of your heating and solar thermal system.
The comprehensive Viessmann product range includes solar collectors, specially developed combi DHW cylinders for use with solar thermal systems, solar control units, the Solar-Divicon pump module for reliable hydraulics and thermal protection of solar thermal systems, plus oil and gas condensing boilers, wood boilers and heat pumps.
Correctly sized solar thermal systems with matching system components cover up to 60 percent of the annual energy demand for DHW heating of detached and two-family houses, or up to 35 percent of the total demand of low energy houses for DHW and central heating.
With Vitoconnect 100 and a smartphone, operating Viessmann heating systems couldn't be easier. The Vitotrol app enables the remote control of heating systems in conjunction with solar collectors. The app is available for mobile devices with iOS or Android operating systems.
When you choose flat-plate collectors from Viessmann, you know you can count on our high quality and technical expertise thanks to more than 40 years' experience in developing and manufacturing solar thermal systems.
All Viessmann heating systems are designed to work in combination with solar technology, so you can opt for a heat pump, a wood heating system or a new oil or gas condensing boiler to complement your collectors as you wish.
