Vaillant boilers are highly recommended throughout Europe for their efficiency and environmentally friendly designs. The Vaillant ecoTEC range of domestic boilers are made with the highest quality components and are backed up with market leading guarantee packages. 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 a smaller water requirement,Vaillant combination boilers heat hot water as required. Vaillant combi boilers are the most energy efficient boilers in theVaillant range as there is no need to install a cold water tank or hot water cylinder, as the boiler connects directly to the mains supply. 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 boiler, especially if more than one tap is being used at the same time. Prices range from £875 to £1305 with varying dimensions, flow rates and outputs.

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 as is the case with 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 £826 to £1257 with varying outputs to suit any home.

Vaillant Heat Only Boilers Price Range– Great For Larger Properties

Vaillant heat only boilers (often referred to as open vent 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.

    Have just had this boiler installed and find it to be very efficient . Providing heat around the home and hot water when needed. Very happy.

  2. Rating:3

    We have just had a Vaillant Ecotec boiler installed – not yet moved into the house but have the underfloor heating on. The boiler is installed in a very small hallway/lobby and we have noticed how much heat is being emitted from the boiler itself It is very significant so I am wondering about the insulation of the boiler itself. We would have thought the boiler these days would be very well insulated. Are there any views on this aspect.

  3. Rating:3

    Repairs had last been done about 10 years ago to a Vaillant Combi Boiler as per Br Gas recommendations, and so served 2 sinks, and 3 plus radiators (kitchen, bedroom, sitting room plus 1 small bathroom).
