All our products at a glance
At Vaillant, we offer different types of gas boilers to suit every living space. There are three main types of boilers available, combi, system and regular (sometimes called open-vent and conventional boilers).
To figure out the best one for you, you must consider the size of your home, how much heating and hot water you need, and your budget.
Combination boilers are suitable for smaller properties with both hot water and central heating needs, while system boilers are better for higher hot water demands and require a water cylinder. Regular boilers are best for homes with simultaneous hot water usage in multiple rooms, also requiring a cylinder for storage.
If you’re upgrading your system or want a like for like replacement, our boilers offer the highest quality, reliability and performance with guarantees of up to 10 years available.
Heat pumps work by extracting thermal energy and converting it into heating and hot water to your home. This can help to reduce your home’s carbon footprint by replacing the reliance on fossil fuels with a more renewable energy source.
Air source heat pumps are the UK’s most popular heat pump as they are suitable for most homes and use energy from the outside air, requiring less additional installation. Ground source heat pumps use either a ground array or a borehole system to extract heat from the ground. Water source heat pumps meanwhile use submerged pipework for energy extraction and are the most energy efficient heat pump, but are also the most limited in their suitability.
Vaillant heat pumps are designed and tested to operate in extreme cold, and most are also Quiet Mark awarded as some of the quietest heat pumps on the market.
We produce a range of thermostats and controls to help you manage your heating and hot water needs. Our eBUS software allows Vaillant controls to communicate seamlessly with the rest of your Vaillant heating system. This technology allows you to be fully in charge of your heating, helping you to save money on energy bills, as well as make your home more energy-efficient.
We offer a variety of control options to suit your household needs, from simple analogue timers for easy of use, programmable room thermostats for households with regular routines, or internet connected SMART controls that work alongside our companion app for total heating system control wherever you are.
Many of our internet-connected controls can also be paired with our thermostatic radiator valves for room by room temperature control.
Vaillant hot water cylinders are expertly designed and engineered to work in perfect harmony with your Vaillant heating system, whether they are working alongside a heat pump or boiler.
Hot water cylinders (also known as hot water tanks) are used to store heated water ready for use, and are a required part of any heating system featuring a system boiler, open vent boiler, or a renewable solutions such as a heat pump. These heating systems often use cylinders due to their large capacity for water storage, making system/open vent boilers and heating systems the recommended choice for homes with high heating requirements.

Vaillant has teamed up with Kevin McCloud to help demystify the process of heat pump installation, and how modernising with a heat pump has benefited homeowners in a wide variety of homes.
As part of the heat pump challenge, we have also being working to help answer the common queries about the practicalities of installing and living with this type of low-carbon heating technology.
