Vaillant System Boiler Price Range

System boilers are pressurized insulated systems. A filling mechanism draws cold water straight from the main supply, eliminating the need for cold water storage.

They work with an external hot water cylinder to store and deliver hot water to multiple outlets simultaneously.

They’re distinct from regular boilers and have more internal components, including a water pump.

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, and outputs vary to suit any home.

Vaillant Regular Boilers Price Range – Ideal for Larger Properties

Vaillant regular or heat-only boilers are energy-efficient and reliable, making them ideal for homes with traditional open-vented heating systems.

The boiler works with a cold water tank, and hot water storage cylinder to offer hot water and heating.

It doesn’t get water from the mains or provide hot water on demand.

Instead, water enters the cold-water tank, usually positioned in higher areas of the house, such as the attic or loft. Gravity aids in getting the water from the cold-water tank to the boiler.

The boiler then heats the water and feeds it into the storage cylinder. It can also provide hot water to the radiators once it has started.

Vaillant regular boilers cost from £796 to £1430 and are offered with varying power outputs (shown in kilowatts or kW).

The Vaillant regular boiler range has been developed with small, medium, and large homes in mind, and includes:

Vaillant ecoFIT Pure Regular12 – 35kWSmall, medium, and large-sized homes with more than one bathroom£730 – £1,440
