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 this 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.
