A new boiler can be a significant investment. The cost of a new boiler can range from £500 - £2,500, and that's excluding the installation cost!

New boilers are usually more energy efficient, meaning that whilst boiler replacement can be costly, it can also save money in the long term.

Normally a like-for-like boiler swap can be done in a day. This will obviously depend on how much other work is needed to upgrade your system to meet latest efficiency guidelines. Don’t forget, your new Vaillant boiler will work at it’s best using Vaillant controls.

A requirement for a heating system installation is that it is Boiler Plus compliant. This means by law, your heating system must have an efficiency rating of at least 92%. The best way to comply with Boiler Plus and to be efficient is to fit a Vaillant control.

Also, an annual inspection by a technician is required to ensure your new heating system remains reliable and most of all run safely. A well-maintained heating appliance is also more efficient.

Regular maintenance is essential. It will also increase the lifespan of your heating system.

A trained technician checks whether all the safety functions are intact. They clean the appliance and perform checks, for example on boiler emissions. All prescribed maintenance work is defined in the installation and service manuals. We train our technicians regularly.

Vaillant offers maintenance agreements that bundle all the services associated with the heating system into one package. This saves you time, effort and money.

You will recognise the energy label from other household appliances, such as washing machines or fridges. The energy classes from A ++ (lowest energy consumption) to G (highest energy consumption) have been in effect since 2015 and also apply to heating systems. The label shows you whether a heating appliance is especially efficient, meaning if it uses the energy as optimally as possible.

By adding extra components to your system, you can further enhance the efficiency class. For example, if you combine your new Vaillant heating system with a regulating control, you can often achieve efficiency class A+.

We offer a great number of heating control options ranging from simple room thermostats through to Smart Home controls:

Basic thermostats keep the set room temperature constant and let you create heating profiles.

Weather-compensation controls adjust the supply temperature of the heating in line with the outside temperature, reducing consumption.

Smart heating controls can do even more. For example, you can use a smartphone or tablet to adjust settings also when you are not at home.
