Let’s get this show on the road!

What’s in this guide?

Who is Vaillant?

The Vaillant Group are an international company who has operations in 20 countries, with over 140 years of experience in the industry and provides the design and manufacturing of heating products and accessories.

They specialise in creating boilers and heating systems that are specifically geared towards utilising renewable energy such as solar and thermal energies.

This can help you to become more eco-friendly and energy efficient, with options available for both your domestic and commercial needs.

Vaillant Combination Boiler Prices

Combination boilers are some of the most popular types of boiler on the market today because they are compact, easy to install and don’t require any room for a cold water tank or hot water cylinder.

This is because combination boilers take water from your mains, heats it and delivers it directly to your taps or central heating system.

They can offer customers an affordable all in one solution, which can typically fit within your kitchen cupboard or utility room.

Vaillant combination boilers provide you with lower running costs, an affordable initial purchase price and high water flow rate.

Let’s take a look at some of the prices you can expect.

Vaillant System Boiler Prices

System boilers take water from your mains, which is why they won’t require a cold water tank. However, they do need a hot water cylinder to store your hot water for use in your taps and showers.

One of the main benefits to choosing a system boiler for your home is that you can benefit from being able to use hot water in multiple locations, for instance in your bathroom and kitchen at the same time.

However, one of the disadvantages is that once your hot water has run out, you will need to wait for more to be heated up.

Vaillant offers its customers a range of system boilers which provide various power outputs, suitable for one bedroom flats and larger homes too.

These types of boilers might be more suitable for medium to large homes with more hot water requirements.

Vaillant Heat Only Boiler Prices

Regular boilers, unlike combination boilers, require both a cold water tank and a hot water cylinder, to store all of your water to be used in your taps and your central heating systems.

This type of boiler might be best suited to large homes who have a lot of water requirements, who want to be able to benefit from great water pressure in several locations at the same time.

Vaillant regular boilers come in a variety of power output and prices, often costing less than their other types of boilers.

Although, you will have to consider the cost for a cold water tank and hot water cylinder too.

Here are some of the typical costs that you can expect from Vaillant.
