Vaillant boilers are highly recommended throughout Europe for their efficiency and environmentally friendly designs.

With a broad range of combination, system and open vent boilers available, the Vaillant ecoTEC range will provide the perfect boiler for your home.
Vaillant Combi Boilers Price Range – Hot Water On Demand
Perfect for homes with limited space and/or smaller water requirements, Vaillant combination boilers heat water only when hot water is needed. Vaillant combi boilers are the most energy efficient boilers in the Vaillant range because they connect directly to the mains supply and don’t require a cold water tank or hot water cylinder. The only disadvantage to this type of boiler is that water pressure may not be as high as it would be with other types of boilers, especially if more than one tap is being used at the same time. Prices range from £850 to £1,920 with varying dimensions, flow rates and outputs.
Below, you can compare each combi boiler series currently available from Vaillant and find out which options are best suited to your home and needs:
Combi Gas Boiler | Sizes | Size Of Home | Price |

Vaillant System Boilers Price Range – Eco-Friendly & Adaptable
System boilers are also known as sealed system boilers and provide hot water via a sealed system tank, which is usually housed in an airing cupboard. They do not require a cold water tank in the loft (unlike an open vent boiler) and they are advantageous in terms of satisfying high hot water demands. Vaillant system boilers can also be used in conjunction with other renewable energy heating systems such as solar thermal. Prices range from £780 to £2,800 with varying outputs to suit any home.
Designed for homes with greater hot water requirements, the Vaillant system boiler range includes the following options:
System Gas Boiler Series | Sizes | Sizes Of Home | Price |
---|---|---|---|
Vaillant ecoTEC Plus System | 12 – 37kW | Small, medium and large-sized homes with multiple bathrooms | £780 – £1,370 |
Vaillant ecoFIT Pure System | 12 – 30kW | Small, medium and large-sized homes with multiple bathrooms | £840 – £1,160 |
Vaillant ecoTEC Exclusive with Green iQ System | 27kW | Medium to large-sized homes with multiple bathrooms | £1,300 |
Vaillant ecoTEC Plus 48kW & 64kW System | 48 – 64kW | Large homes with multiple bathrooms | £2,200 – £2,600 |
Vaillant ecoTEC 46kW & 65kW System | 46 -65kW | Commercial buildings and large homes with multiple bathrooms | £2,200 – £2,800 |
Vaillant Regular Boilers Price Range – Great For Larger Properties
Vaillant regular boilers (often referred to as open vent, heat only or conventional boilers) provide central heating and hot water via a boiler, a storage cylinder (which is usually housed in the airing cupboard), as well as a cold water tank in the loft. The tank in the loft draws water from the mains supply and then feeds the hot water cylinder. The water is then heated by the boiler and can be distributed throughout the property. It might take time to reheat once the water runs out due to it being cylinder driven but you can use taps, showers and baths in different rooms at the same time which is a necessity for larger families. Prices range from £796 to £1430 with varying outputs.
The Vaillant regular boiler range has been developed with small, medium and large homes in mind, and includes:
Regular Gas Boiler Series | Sizes | Size Of Home | Price |
---|---|---|---|
Vaillant ecoFIT Pure Regular | 12 – 35kW | Small, medium and large-sized homes with more than one bathroom | £730 – £1,440 |
Vaillant ecoTEC Plus Regular | 12 – 35kW | Small, medium and large-sized homes with more than one bathroom | £720 – £1,520 |

Key Questions for selecting your Boiler Installer
Ask your advisor key questions which will help make your decision on which boiler is right for you and your home. The key question is price and whether they will stick to the quote after the installation. Make sure there are no hidden costs. Ask them questions on their payment terms. How do these match against your own requirements? Do they install only A rated energy efficient boilers? Energy efficient boilers will save you money.
Crucially, make sure you review their safety record and expertise. All boiler installations today are done by Gas Safe Registered engineers. This ensures it’s done safely and legally. Another consideration is the flexibility on when your installer can fit your new boiler. Make sure their timescales are convenient to you. Lastly, ask them if they offer boiler insurance as part of their service. You’d be looking for the first year of cover to be free.
Comparing Boiler Quotes and Prices
For the best and cheapest boiler price, you will have to do some shopping around. Get a a quote from a national installer and a local boiler installer. Compare them on the cost of the boiler and the price of installation. Average installation costs are between £1,500 – £1,800. Comparing Vaillant Gas boilers prices could save you hundreds of pounds so it’s worth doing.
