Still operating as a successful family business today, Vaillant continues to pioneer and stratify energy efficiency blended with heating functionality and application throughout their products.

What is ecoTEC?

As mentioned Vaillant cares about the environment and wants their boilers to reflect this respect and consideration. The ecoTEC range is Vaillant’s premium environmentally friendly heating range, designed to keep your property warm while being kind to the environment.

Green IQ

Vaillant’s Green IQ hallmark ensures ultimate energy efficiency, providing the lowest fuel consumption rates and subsequently the lowest fuel bills.

What Is A System Boiler?

A system boiler links with a hot water storage cylinder to provide a home with central heating and hot water. It does this by taking cold water directly from the mains (instead of a cold water storage tank) and heating it via an internal heat exchanger, this transfers gas energy to water. The hot water is then moved to the hot water cylinder for storage.

Unlike some regular boilers, such as oil or heat only, that use bulky external components, with a system boiler the majority of components are integrated within the appliance. The only external part is the aforementioned hot water storage cylinder; This is a much smaller unit than some of the other hot water storage tank systems used by regular boilers, these tend to eat up an excessive amount of loft space.

Benefits Of System Boilers

  • System boilers can cope with the demand of several outlets i.e multiple taps needing hot water at the same time. This makes a system boiler suitable for servicing properties with more than one bathroom.

  • System boilers can often be installed by a Gas Safe engineer faster than many other boiler types.

  • Due to an internal pump, and a banked body of hot water, system boilers can produce a stream of hot water on demand quicker than heat only boilers for example.
