Vaillant boilers: taking a place in history

You might recognise the famous rabbit logo that’s associated with Vaillant boilers, but did you know that the company has actually been around since 1874? Back in the day when Johann Vaillant set up a master fitter’s business, it only took him until 1894 to create the first device that could heat hot water hygienically. The rest, as they say, is history.

Did you know? Vaillant Group started off as a familyrun business. And it remains so to this day!

Exploring the range of Vaillant boilers

When you plan on getting a new boiler, it can be tough deciding on where to start. Which type of boiler do you go for? How do you know if it’s the right one for your house? And what’s the best way to pay for it? Before getting started, you can check out our guide to boiler types and you’ll soon be an expert on the differences between combi boilers, system boilers and conventional boilers.

Vaillant specialises in providing gas boiler solutions to fit in any kind of living space, and consistently gets positive feedback from their customers for reliability and performance.

Vaillant combi boilers

Small in size and ideal for homes that don’t need lots of hot water (for example, those with only one bathroom), Vaillant makes some of the best combi boilers around. With a Vaillant combi boiler, there’s no need for a water storage tank and you get hot water as soon as you turn on the hot water tap. Vaillant combi boilers are built in Vaillant’s RoSPA gold award-winning Derbyshire manufacturing plant and have Quiet Mark accreditation. So if you want hot water on demand with a boiler that runs smoothly and quietly in the background, Vaillant combi boilers such as the vaillant ecoTEC range will supply you with heating and hot water quietly and efficiently and would be a great fit for your home. And when you buy from us, we make sure they fit great too!

Vaillant system boilers

For larger family homes that need a lot of hot water and have more than one bathroom, Vaillant system boilers are built to deliver. System boilers use a separate hot water cylinder in the loft, so once you’ve put the hot water on, you’ll be able to use it in showers and sinks around the house. They’re a bit bigger than a combi though, so you’ll need some more space for one of these.

Vaillant open vent boilers

Also known as conventional or regular boilers, these types of boilers all work the same, despite the many names given to them! This boiler system has a hot water cylinder (usually in the airing cupboard) and a cold water tank in the loft. They’re great for larger households where more than one person will be using hot water at the same time, especially if they have low water pressure.
