Our thoughts:

The Vaillant ecoTEC plus combination store Boiler is perfect for large homes with heavy hot water demands. It doesn’t require a water cylinder or tank to operate, making it perfect if you want to prioritise space management in your installation. It can produce up to 20 litres a minute and replenish quickly, meaning you can guarantee hot water should always be available when you need it.

Manufactured in the UK

The Vaillant ecoTEC plus combination store is hand-built in the Vaillant factory in Derbyshire, UK.

Wide availability of parts 

The ecoTEC plus combination store is manufactured in the UK. If you ever need a replacement part you can find them at Screwfix, Plumbase and other plumbing merchants both in-store and online.

A global brand

Vaillant has won awards for its boiler design. Designed in Germany and manufactured in Derbyshire, they are synonymous with engineering prowess and high-quality components.

However, it is worth noting that other boilers do offer a higher energy efficiency rating for similar outputs as with the ecoTEC plus combination store.

Choose from a range of control options

With the Vaillant ecoTEC boilers, you can opt to control heating and hot water via the standard manual control panel on the boiler itself. You also have the option to install a complimentary smart heating system and integrate with Vaillant’s vSMART™. Utilising smart technology, you can control heating remotely with compatible Android and iOs operating system smartphones.

You can also benefit from Vaillant’s VRC 700 heating control. This intelligent system is particularly recommended if you have multiple heating zones, underfloor heating or you use renewable technologies. It allows you to manage the heating on a room by room basis, control efficiency and account for external weather temperatures automatically.

Reduce gas and electricity consumption

The UK government has announced that the country will meet net-zero emissions rating by 2030. The energy market remains volatile, so seeking an economical boiler should be a priority for homeowners when replacing a boiler.

Vaillant can help you reduce your household’s carbon emissions and save money on your energy bills. The stainless steel heat exchanger provides exceptional heat transfer and efficient performance, even during freezing temperatures.
