Vaillant Boilers: Compare Efficiency, Warranty & Price
Vaillant’s award-winning combi, system and open vent boilers are renowned for their reliability, performance and efficiency. As well as efficient gas combi, regular and system boilers, Vaillant have also been making waves in renewable heating with their own range of heat pumps.
There are a few things that you should look out for when comparing boilers, including output rating, efficiency, warranty and the potential cost. We explain each of these in more detail below.
- Output: This is the power of the boiler. Measured in kilowatts (kW), the output rating is one of the most important things to consider when comparing replacement boilers. The right output to suit the heating and hot water demands of your home is essential, as an output that’s too low won’t meet demand and an output that’s too high could increase your energy bills.
- Efficiency: Gas is an effective way of heating the home but when burnt there is some waste. The amount of fuel that’s turned into usable energy is reflected in the efficiency rating. Vaillant boilers are well known for being highly efficient.
- Warranty: A promise from the manufacturer that they will see that you’re protected after the installation of your new boiler. Vaillant boilers have warranties of 2-7 years depending on the model and whether certain terms are met.
- Price: Vaillant are one of the leading UK boiler manufacturers with prices of around £1,000.

Compare the costs of Vaillant combi boilers
Combi boilers are the best option for homes with 1-2 bathrooms. They deliver hot water on demand rather than storing it in a cylinder; as system and regular boilers do. This means that you never have to wait for the cylinder to fill up, giving you instant access to hot water. Vaillant were pioneers of the combi boiler* and they have a number of reliable and efficient units at various price points, so you are sure to find the right boiler to fit your budget.
Compare Vaillant Regular boiler prices
Regular boilers are the best option if your home is already being heated by a regular boiler. Otherwise, a combi or system boiler would make for a much more straightforward installation. With output ratings of 15 kW up to 35 kW, there will be a suitable Vaillant regular boiler for a range of property types.
Compare Vaillant system boiler prices
There are plenty of options in the Vaillant system range of boilers, so you should be able to find something that ticks your boxes. No matter what your heating and water requirements are, there will be an option that doesn’t blow the budget either.

Benefits of Vaillant regular boilers
Choosing a new boiler can be daunting, especially if the existing boiler has been in place for years.
Boilers have changed significantly in the last decade and are more energy efficient than ever before.
Vaillant offer the ideal solution for older properties with their regular boiler range.
These are the perfect modern-day replacement for your older boiler and should be close to like-for-like in terms of design and pipework, but with the benefits of a new system.
Benefits of a regular boiler
- Older property? This is an ideal replacement as the pipework will be similar
- It’s fine to use more than one tap at the same time
- Works well with an electric immersion heater as a hot water back-up
- Can be used with solar thermal panels to heat your water
Benefits of Vaillant system boilers
Modern home owners will love the Vaillant system range of boilers, as they’re designed for the way we live today.

The Vaillant system range is the ideal solution for lots of reasons.
- Many heating components are built-in, so installation is easy
- No need for a cold water feed tank means it’s ideal for smaller homes or those without loft space

Vaillant boiler warranty
Every boiler manufacturer offers a standard warranty with their boilers which last between 1-10 years. The warranty is your insurance policy and means if a fault develops the manufacturer will resolve it within a specified time frame. Some warranties include both parts and labour, while others may only cover parts. The most important thing to remember is to get your boiler serviced by a Gas Safe registered engineer every year, as failing to do so is likely to invalidate your warranty.
