Oil hybrid heating

Classic combustion plus renewable energy

Oil hybrid heating is the perfect solution for modernising heating systems. It provides the benefits of a reliable oil heating system while lowering heating costs and heating your home in a more eco-friendly manner by using renewable energy.

Two complementary heat generators

  • Combining oil and solar

    Combining an oil condensing boiler with environmentally friendly solar energy reduces your heating oil requirements by 20 to 50%. It is no surprise that this combination is the most popular oil hybrid heating system version.

  • Combining oil and heat pumps

    Combining an oil heating system with a heat pump means your home will be heated exclusively using climate-friendly environmental heat as often as possible. The oil boiler only switches on when the weather is particularly cold or when you need a lot of hot water.

Benefits of WOLF oil hybrid heating systems

Smartset advantages

Precise coordination

Teamwork

WOLF oil hybrid heating combinations are complete systems of precisely coordinated components. The condensing boiler, renewable energy source and thermal storage cylinder work together smoothly as a team. Read more

Perfect control

An intelligent control system in the oil hybrid heating system ensures that every component performs its task to perfection. The shared control system and programming unit make monitoring and operating the system a breeze. It can even be controlled from your smartphone using the WOLF Smartset app. Read more

Save costs

High efficiency

Save heating oil

The precise coordination of WOLF oil hybrid systems exploits all the strengths of the various components to achieve optimum efficiency. The consequence: lower oil consumption and lower heating costs. Read more

Combined for greater reliability

Adding a second heat generator to the oil condensing boiler extends the life of the boiler. Furthermore: you benefit from additional operational reliability as one of the two heat generators will continue to operate if the other malfunctions. Read more

solar thermal

Use renewable energies

Climate-neutral and environmentally friendly

Renewable energies heat your home in a climate-neutral and environmentally friendly way. The higher the proportion, the better.

Independent of oil prices

Renewable energies reduce oil consumption. You can look forward to more stable heating costs and are less dependent on imported fuels.

Do you have any questions?

It can be complex and time-consuming to find the right solution for your home. We can help you to understand everything that is really relevant to your project in only a few minutes.
