Which is the right boiler for my home?

Combi boilers are best suited for smaller homes, where heating and hot water demands aren't extremely high. Hot water is only generated when it is required and doesn't require a water storage tank. Combi boilers are compact in size, meaning you are free to fit the boiler almost anywhere that is safe in the house and can also be cupboard fit.

What is a Combi Boiler?

System boilers are better suited with homes that have more than 1 bathroom and a higher heating and hot water demand than a home with a combi boiler. The high demand for hot water is met with a constant supply which is stored in a water cylinder.

What is a System Boiler?

Open vent boilers (also known as regular boilers) are best suited for homes with mulitple bathrooms that are prone to be used at the same time. You can also fit a regular boiler with renewable solutions such as heat pumps and solar water systems.

  • What will a new boiler cost me?

    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.

  • How long does it take to replace a heating system?

    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.

  • How can I ensure my heating system is always efficient?

    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.

  • How can I ensure my heating system is always 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.

  • What does the energy efficiency class of my heating system mean?

    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+.

  • What heating controls can I use for my new Vaillant heating system?

    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.
