• Output rating: All boilers have an output rating, measured in kilowatts (kW), which shows the power of the unit. Strictly speaking, the higher the output rating, the higher the demand for central heating and domestic hot water a boiler will be able to meet.

• Efficiency: A new boiler should help to lower your energy bills and all boilers have an efficiency rating which displays how much fuel is converted into usable energy for central heating and hot water. Ariston boilers typically have an efficiency rating of around 90% meaning that for every £1 you spend on heating your home, around 10p will be lost to the waste gases expelled through the flue pipe during operation.

• Warranty: In the unlikely event that there’s an issue with your Ariston boiler after the installation, the warranty will see that you’re covered. All boilers will have a warranty attached to them but the length will vary from model to model. Ariston boilers are available with warranties of 1 year right up to 12 years.

• Price: Ariston boilers are typically priced at between £500 and £2,000 giving a suitable option no matter your budget.

Compare Ariston combi boilers

Combi boilers are the most popular boiler type in the UK. This is largely thanks to them being single cost-effective units that don’t require any additional tanks or cylinders. Combi boilers take water directly from the mains and heat it on demand before circulating it round the central heating system or hot water outlet.

To help you find the most suitable boiler for your home, a 24-27 kW combi would be ideal for smaller homes with 1 bathroom and around 10 radiators, while properties with up to 15 radiators should look for an output rating of 28-34 kW.
