Frequently Asked Questions

General FAQs

What is a CHP (Combined Heat and Power) unit and how does it work?

A CHP unit generates electricity and heat simultaneously from a single fuel source (e.g., natural gas, biogas). This increases overall efficiency and reduces energy costs compared to separate generation.

What are the main benefits of installing an XRGI® CHP in my business or property?

Key benefits include reduced energy costs, lower CO₂ emissions, increased energy independence, and compliance with sustainability goals.

Is an XRGI® CHP suitable for apartment complexes, hotels, or industrial facilities?

Yes. XRGI® systems are especially efficient in buildings or operations with a constant heat demand, such as apartment complexes, hotels, care homes, swimming pools and leisure centers, and industrial plants.

How often does an XRGI® CHP require maintenance?

Typical maintenance intervals are between 6,000–10,000 hours, depending on the model and usage. Regular servicing ensures optimal performance and efficiency.

Are there government incentives or subsidies for XRGI® CHP installations?

Yes. In many European countries, there are support schemes, grants, or tax incentives for CHP projects.
Our team can advise you on the programs available in your region.

Technical FAQs

What electrical and thermal efficiency can be expected from an XRGI® CHP?

Depending on the model and fuel type, total efficiency (combined heat and power) can exceed 100% with condensing technology

Which fuels can an XRGI® CHP operate on?

XRGI® CHP units typically run on natural gas, biogas, LPG, or hydrogen blends. The choice depends on availability, cost, and sustainability goals.

How is an XRGI® CHP connected to the existing energy system of a building?

The XRGI® CHP unit is integrated into the building’s heating and electrical infrastructure. It usually operates parallel to the public grid and can be combined with boilers, storage systems, or renewable energy sources.

What happens if the electricity demand is lower than the CHP’s output?

Excess electricity can usually be fed into the public grid (subject to local regulations) or stored with battery systems. Thermal storage can also optimize heat utilization.

What is the expected lifetime of an XRGI® CHP?

With regular maintenance, an XRGI® CHP system can operate reliably for 10–15 years or more, depending on operating hours and load profile.
