Tips for modernisation

Replace heating is generally a very good decision. The higher efficiency of new heating systems significantly reduces the energy consumption of your installation. Replace heating leads to lower operating costs and eases the impact on the environment.

Modernisation does not take much time to complete: In general, a new heating system is installed in a maximum of three days. Especially if it is a Vaillant system, because the components are pre-assembled as far as possible.

When you replace your heating, you can retain the existing energy source, gradually change, or completely switch to renewable energy.

Using an existing energy source with modern technology

Replace your old boiler for a modern high-efficiency boiler with condensing technology. You will significantly reduce the operating costs of your system and protect the environment. Our condensing boilers utilise the heat in the flue gas and thus achieve an energy efficiency of up to 98 per cent. You can reduce fuel consumption by up to 30 per cent compared to an old heating system.

Only minor alterations are necessary - if any - for this quick and easy solution. Only your chimney may need to be converted.

Gradually switch to renewable energy

Most older heaters work inefficiently and emit too much CO₂. Rising fuel prices are also driving up operating costs. Renewable heating systems enable you to become more independent from expensive fossil fuels and protect the climate at the same time. You do not have to invest in everything in one fell swoop. Instead, you can install new equipment as needed.

Saving costs with solar

You can supplement your heating system to use components that utilise renewable energy. For example, you can generate heat for hot water preparation and for heating support with solar collectors. Combined with modern condensing boilers you can cover about 60 per cent of your hot water and 20 per cent of your heating needs. Upgrading is not complicated and can help you to significantly reduce your heating costs.

Completely switching to renewable energy

Are you looking for the most future-proof variant? Then focus entirely on renewable energy. This provides you with autonomy in relation to the rising price of fossil fuels. You then save most operating costs and protect the environment. In many cases, you can most likely also benefit from government subsidies.

Heat pumps: Your own source of energy

Modern heat pumps use the heat from the air, the water or the ground for heating and for hot water preparation. The environment delivers about 75 per cent of your energy requirements. This energy is available all year round and in unlimited quantities. A heat pump works in a very environmentally friendly way because it produces no emissions.

An air/water heat pump is particularly suitable for replacing your heating: No major renovations are needed. The conversion cost and the purchase price are low. But also the installation of a brine/water heat pump or a water/water heat pump can pay off depending on the condition of your property.

The lower the required flow temperature is, the more efficient a heat pump is. Your house should therefore have large heating surfaces that allow operation at low temperatures. Your house should also be well insulated to ensure energy-efficient operation.

Pellet heating: Heating with renewable energy

You can secure a low fuel price by switching to heating with pellets. Pellets are natural products made from wood shavings and sawdust. They are burned in a special wood boiler. Our innovative pellet boiler is carbon neutral, which means it only gives off as much carbon dioxide into the environment as the wood has absorbed during growth.

The boiler covers the heating of one- and two-family homes and is easily integrated into existing systems. It is therefore particularly suitable for replacing your heating. You need a room in your house for the dry storage of the pellets. To operate, simply select one of three convenient refill systems. After that, everything is fully automated. The integrated controller regulates all components. A connected solar system is also available on request, which complements the system wonderfully.

The right heating system

There is no standard solution when searching for the right heating system. But finding the system that fits your needs is not that difficult. Talk with your Vaillant heating installer. They can assist you in planning your new heating installation.
