    Ariston Combi Boiler Prices Range Between £640.95 and £1,409.95 and are Recommended by Good Housekeeping Magazine Readers

    Ariston combi boilers heat water directly from the mains, which means they do not need a separate cold water tank or hot water storage cylinder. Combi boilers (otherwise known as combination boilers) are now the most popular type of boiler in the UK because they don’t take up much space and can provide on-demand hot water for taps and radiators.

    The combi boilers by Ariston are extremely quiet, making them ideal if you plan to keep your new boiler in a busy room. Take the Clas Net One Combi for example, which is built with an improved silencer and the latest soundproofing technology to minimise overall noise levels. Then there’s the Clas HE Evo Combi. In addition to featuring a particularly low level of operating noise, this model is recommended by the readers of Good Housekeeping.

    Endorsed by the Energy Saving Trust, Ariston combi boilers come in varying outputs from 24kW to 38kW, with the larger output delivering the highest hot water flow rate. Prices range from £640.95 to £1,409.95 (including VAT and excluding installation), depending on the required model and output.

    Ideal for homes with more than one bathroom, Ariston system boilers have in-built hot water components and require nothing more than a separate hot water storage cylinder so there is no need for a cold water tank in the loft. One of the major advantages of these system boilers is that they provide plenty of hot water to any number of taps at the same time.

    The Ariston system boiler range, which includes the Clas System One and the E System One, has been tested and certified for quality, safety and usability by a well-known independent body. Both models come with a ‘comfort’ mode to deliver hot water instantaneously, along with frontal access to components to make installation and servicing neater and less disruptive.

    These highly efficient system boilers are available in different outputs from 18kW to 30kW and have warranties that range between 2 and 8 years. When it comes to costs, prices start at £739.95 and go up to around £1,122.95 with VAT and minus the fitting fees.

    Ariston Regular Boiler Prices Range Around £640.95 and are Designed for More Efficient Home Heating

    Ariston’s regular boilers (also known as conventional, traditional or heat only boilers) are recommended for larger households that use a large amount of hot water and have an open vented system. They’re also a sensible option for properties situated in areas where water pressure is low. The only drawback with a regular boiler is that it must be installed alongside both a separate hot water tank (usually in the loft) and a cylinder for storing hot water (usually in the airing cupboard).

    The Ariston regular boiler range currently consists of just one model – the Clas HE Regular boiler in an output of 24kW. It has extremely compact dimensions and includes an auto-diagnostic system for hassle-free fault diagnosis and two temperature zone capability to enable the boiler to supply a different temperature of hot water to radiators in two different parts of the home.

    This model comes in at around £640.95 and is a cost-effective solution that features advanced technology to help you save on your energy bills. The Clas HE Regular is also supported by a 5-year warranty and can be made even more efficient with a range of optional controls.

    Always Compare Ariston Boiler Prices and Installation Costs

    If you’re considering a new Ariston boiler, it’s always best to get a minimum of three quotes on the boiler and installation. This way, you can compare prices and make sure you’re getting the best deal available. Once you’ve purchased an Ariston boiler and had it installed, remember to register your warranty within 30 days of the date of installation via the Ariston website.

    Choose a Gas Safe Registered Engineer

    Before selecting an installer to fit your new Ariston boiler, it’s important to make sure they are listed on the Gas Safe Register and legally permitted to carry out the work you need doing. To check a business or engineer, use the online search at the official Gas Safe Register website. You can also ask to view the engineer’s Gas Safe ID card, which should clearly state whether they are qualified and competent to fit your gas boiler. When checking an ID card, don’t forget to look at the ‘valid from’ and ‘expiry’ dates as well.
