Why choose Vaillant

Vaillant is one of the most established German brands in home heating, a byword for reliability, long-term durability and high-efficiency technologies. The range covers condensing boilers and heat pumps designed to cut consumption and deliver consistent comfort in every season. All products are covered by an official warranty, with easily available spare parts and qualified support.

Vaillant condensing boilers

Vaillant condensing boilers recover the heat from flue gases and reuse it, achieving high efficiency and lower gas consumption than a traditional boiler. They are the ideal choice for anyone wanting to replace an old system and obtain real savings on their bills. You will find models suited to both domestic hot water and heating, in various power ratings in kW for apartments and detached homes. Discover the full condensing boilers category and the wall-mounted wall-hung boilers.

Vaillant heat pumps

Vaillant heat pumps harness the energy in the air to heat rooms and produce hot water with low electricity consumption. They are an efficient, sustainable solution, perfect to pair with underfloor heating or low-temperature radiators. They represent a step towards cleaner heating, and in many cases they can qualify for the tax incentives provided by regulations.

How to choose the right power in kW

The power of a boiler or heat pump is measured in kW and should be chosen based on the home's floor area, insulation and the number of bathrooms served. Here is a general guide:

  • Up to 24 kW: medium-sized apartments with a single bathroom.
  • From 28 to 35 kW: larger homes or those with two bathrooms and higher hot water demand.
  • Over 35 kW: detached houses, villas and systems with high requirements.

To produce domestic hot water efficiently, you can also consider a heat pump water heater to pair with the system.

Efficiency, savings and tax incentives

Investing in a Vaillant product means betting on energy efficiency and lower consumption over time. The purchase and installation of condensing boilers and heat pumps may qualify for tax incentives where applicable, such as reduced VAT for renovation work. The conditions depend on the type of work, so it is worth checking the up-to-date requirements before buying.

Support, warranty and installation

At ClimaConvenienza you will find the Vaillant range with the official manufacturer's warranty, available spare parts and qualified support. Many products are ready to ship, and in several cases you can request installation by specialised technicians. Prices range from around 45 euros for accessories up to over 9000 euros for the most complete systems, covering every system and budget requirement.

Frequently asked questions

How many kW should a Vaillant boiler have for an apartment?
For a medium-sized apartment with a single bathroom, up to 24 kW is usually enough. For larger homes or those with two bathrooms, it is better to go up to a power between 28 and 35 kW, depending on hot water demand.
What is the difference between a Vaillant condensing boiler and a heat pump?
The condensing boiler burns gas while recovering the heat from flue gases, whereas the heat pump harnesses the energy in the air with low electricity consumption. The heat pump is more efficient and sustainable, especially when paired with low-temperature systems.
Do Vaillant boilers and heat pumps come with the official warranty?
Yes, all Vaillant products sold at ClimaConvenienza are covered by the official manufacturer's warranty, with available spare parts and qualified support across the territory.
Can I get reduced VAT or tax incentives on a Vaillant product?
In many cases yes, when the installation is part of renovation or energy upgrade work. The application of reduced VAT and incentives depends on the type of work and the documentation, so it is worth checking the up-to-date requirements.
Is it worth switching to a Vaillant condensing boiler?
Yes, replacing an old system with a Vaillant condensing boiler reduces gas consumption thanks to its high efficiency. The savings on your bills are more noticeable when the system is well sized and used throughout the cold season.
Are Vaillant products available ready to ship?
Many Vaillant models are available ready to ship. The range covers prices from around 45 euros for accessories up to over 9000 euros for the most complete systems, with the option of installation by specialised technicians.
