Frequently asked questions

Modern heat pumps are very efficient even at low outdoor temperatures. They can extract heat from the environment even in frosty conditions and are therefore a reliable energy source throughout winter.

Thanks to our expertise and modern technology, we can seamlessly integrate renewable energy systems into existing infrastructure – whether in new buildings or when modernising older properties.

Like all technical installations, renewable energy systems also require regular maintenance. The exact requirements vary depending on the technology, but we offer comprehensive maintenance contracts to ensure a long service life and optimal performance.

The systems are designed to significantly reduce CO₂ emissions. The exact savings depend on the system in question, but we prioritise maximum efficiency and sustainability.

There is a wide range of subsidy programmes at both state and federal level. We are happy to advise you in detail on the current options and provide support with applications.

Profitability depends on various factors, including the size of the project and the chosen technology. In general, such systems often pay for themselves within a few years, not least thanks to government subsidies and saved energy costs.

We offer a wide range of solutions, including heat pumps, photovoltaic systems, fuel cell heating & CHP systems, to name just a few.

Our team consists of experienced specialists with comprehensive training and certification in pipeline construction.

Safety is our top priority. We strictly adhere to all safety regulations and standards and ensure our teams are always trained and properly equipped.

Sustainability matters to us. Old materials are recycled wherever possible, and we ensure environmentally responsible disposal of waste.

With regular maintenance and depending on the material, pipeline systems can last several decades.

Yes, we offer regular maintenance and inspection services to ensure the longevity and efficiency of the system.

Pressure systems use pumps to push liquids or gases through the pipes, while gravity systems use the natural fall of the liquid. The choice depends on the specific requirements of the project.

After completing installation work, we carry out extensive pressure and leak tests to ensure everything is functioning properly.

Yes, we have extensive experience retrofitting pipelines in existing buildings, whether for modernisations or expansions.

We use a wide range of materials depending on the application, including copper, stainless steel, galvanised steel and modern plastics. Each material has its own advantages depending on project requirements.

Our prices for service calls can be found on the Pricing page. You can easily calculate the cost of a heating service using our heating maintenance calculator. For project-based work, costs depend on the scope and requirements. We're happy to provide a personalised quote.

Yes, we have a wide range of successfully completed projects. We'd be happy to show you some of our references.

Our focus is on individual solutions, appreciative treatment and needs-orientation. We also value clear communication and a positive mindset.

We specialise in the new build & modernisation of HVAC systems in public & commercial buildings, as well as consultation through to commissioning of HVAC systems for single- and multi-family homes.

You can call us at any time. We offer an emergency service and will be on site quickly to resolve the problem.

Spring or summer is ideal for maintenance, before the heating season begins. This way you're perfectly prepared for the colder months.

A sign of an inefficient heating system is rising energy costs. Regular maintenance and inspection by our team can help identify problems early.

A standard maintenance service usually takes 1–2 hours, depending on the system and its condition.

Regular maintenance extends the lifespan of your systems, reduces energy consumption and prevents costly repairs through early problem identification.

No. While a maintenance service is about maintaining the current condition of the system, the heating check goes further and generates comprehensive recommendations for improving heating operation and its efficiency.

Costs differ depending on the type of system to be serviced and any additional equipment included. You can easily calculate the cost of a maintenance service for your specific system using our maintenance calculator.

Maintenance and repair are two distinct services. Maintenance aims to preserve the current operating condition of the heating system. It is carried out on functional equipment, without in-depth fault diagnosis or repairs. Maintenance is a long-term preventive measure. A repair, on the other hand, is carried out when a fault or defect has already occurred.

Maintenance includes checking the controls and safety devices, cleaning the boiler and burner, measuring and checking flue gas values, and replacing wear parts.

Regular heating maintenance makes sense for many reasons. Among other things, proper maintenance can help avoid costly repairs. A heating system also consumes less energy when it is professionally serviced, which permanently reduces costs.

The heating system should be serviced once a year – ideally in summer or at the very beginning of the heating season.

We offer a wide range of heating systems, including gas heating, but above all renewable energy systems such as heat pumps and PV systems.

No, the quote from the heating calculator is non-binding. After an on-site assessment we can provide you with a binding offer.

Absolutely! Once you have received your quote, you are welcome to arrange an appointment with us to discuss the next steps.

You should have information about your current heating system, the year of construction of your building and the floor area to hand.

A modern heating system is more energy-efficient, leading to lower heating costs, and it contributes to environmental protection through reduced CO₂ emissions.

The quote is generated immediately after you enter your details and displayed to you straight away.

Of course! Just enter the information you have. For a precise quote we can then clarify the details together.
