Project 01
12.14 kW
Vaillant heat pump, detached house 12.5 kW
In this project in Extertal, an outdated heating system was replaced by a highly efficient air-to-water heat pump with 12.14 kW of heat output and an 8.6 kW immersion heater. The goal: make the house independent of fossil fuels and bring heating costs down for good.

“Solar system” is the umbrella term for systems that absorb and convert solar energy. Photovoltaic systems are solar systems that convert sunlight into electrical energy. The WER Gruppe specialises in tailor-made PV systems.
Storage is worthwhile to use as much of your cheap solar power as possible yourself — even when the sun isn’t shining. This way you reach a self-sufficiency level of up to 80 %. A PV system also works without storage, of course.
PV modules: 30-year warranty. Inverters: 10 years. Battery storage: 10 years. Our warranties give you the security you need for your investment in renewable energy.
We guarantee fast delivery and installation within 8 weeks of signing the contract. So you can benefit from your sustainable energy supply quickly.
Absolutely — that’s especially efficient. As WER Gruppe we plan PV, storage and heat pump together so everything works optimally as one.
