Gas hybrid heating

The best of two worlds

A gas hybrid system brings together proven gas heating technology with renewable energy sources, which cuts heating bills and lowers your gas consumption.

Flexible combination options

  • Gas and solar combinations

    The combination of a gas condensing boiler and solar thermal technology is a widely used form of gas hybrid heating. Using environmentally friendly solar energy can lower your gas consumption by 20 to 50%.

    Hybrid system with gas condensing boiler and solar thermal energy

  • Gas and heat pump combinations

    With this form of gas hybrid heating, you heat your home using climate-friendly environmental heat for most of the year. The gas appliance only provides additional heating when it gets very cold outside.

Benefits of WOLF gas hybrid systems

smarthome

Coordinated and centrally controlled

The perfect team

WOLF supplies gas hybrid heating systems as coordinated complete systems. Condensing boilers, renewable energies and thermal storage cylinders form a well-matched team.

Intelligent control

All components work together via the intelligent control system. This also makes it easier for users to configure the systems using the shared programming unit or with the WOLF Smartset app. Read more

Save costs

Outstandingly energy efficient

Reduces gas bills

Hybrid systems exploit the respective strengths of both technologies and are particularly efficient. This slashes your gas bills.

Two heat generators

The combination of two heat generators extends the service life of the gas heating system. It also keeps the overall system in operation – if one part malfunctions, the other can still carry on heating. Read more

solar thermal

Heating with a high share of renewable energy:

Climate-conscious

These systems use a high proportion of renewable energy so you can heat your home in a climate-conscious and environmentally friendly way.

Future-oriented

Using renewable energies reduces your dependence on imported fuels.

The components of a gas hybrid heating system

WOLF gas condensing boilers modulate their output continuously. This means that they can always supply as much heating warmth as the hybrid system currently requires from the gas component.
