Ariston has been established in the heating industry since 1960 and today provides millions of families in over 150 countries with efficient and high quality solutions through innovative Italian design.
They manufacture combi, system and regular boilers, all of which run on natural gas while LPG conversion is available on some models which is great news for properties that aren’t connected to the gas network. Each boiler type has its own pros and cons which you’ll need to weigh up when looking for a new boiler as one type of boiler will be better suited to your home than another. As well as finding the right boiler type, you will need the most suitable model which means comparing the output rating, efficiency, warranty and price.
- 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 all of the boilers manufactured by Ariston using our Boiler Comparison Tool which contains output rating, efficiency and warranty length. You can compare up to 4 boilers by tapping the ‘add boiler’ symbol. Tip: include your existing boiler as part of the comparison to find a better model.
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.
Compare Ariston regular boilers
Regular boilers, also known as conventional or heat-only boilers, are the oldest type of heating system and are often found in older traditional properties. Ariston have now discontinued their sole regular boiler.

Compare Ariston system boilers
System boilers heat water from the mains and circulate it round the central heating system or for storage in a hot water cylinder. Ariston system boilers have output ratings of 18 kW up to 30 kW making them a great option for small to medium sized homes with 1-2 bathrooms.

Benefits of Ariston system boilers
One of the major advantages of a system boiler is that it heats hot water directly from the mains so there is no need for a cold water tank in the loft but you do need a hot water cylinder to store hot water.
If your home gets through a large amount of hot water then this could be the choice for you. This is an ideal option for those with multiple bathrooms.
Ariston System boilers provide powerful heating performance, reliability and, of course, money saving efficiency.

If you think it’s time to start saving money with your new Ariston System boiler the next step is to do find a minimum of three installation quotes from different engineers as the price for this can vary. A heating engineer can recommend the best boiler and heating system for your needs including the output (size) you’ll need.
There are a few things to consider such as the upfront cost of installation, annual servicing and any repairs needed during the lifetime of your new boiler, but there’s always a bright side; think of all the money you could be saving on your energy bills! Get quotes for a new Ariston boiler.
Benefits of Ariston regular boilers
If you’re replacing an older, traditional boiler then a new Ariston regular boiler will still need similar pipework to connect the three elements needed (boiler, water tank and cylinder).
Rather than changing to a completely different type of heating system such as the ‘all-in-one’ Combi boiler, replacing with a modernised Regular boiler will reduce complexity during installation and reduce your costs while still providing a better level of energy efficiency than your old boiler.
A compact and stylish unit like Ariston’s with advanced control system and ‘AUTO’ function technology will continuously respond to the temperature of your home ensuring peak performance at all times, improved energy efficiency and money savings.
- Suitable for older properties with a traditional central heating system in place
- Gives plenty of hot water for standard use
- 5 year warranty
- ‘AUTO’ function technology
- Stainless steel heat exchanger
- Easy to use and install
- Compact and quiet
- ‘A’ ErP rated for optimum energy efficiency
- Auto-diagnostic system
- Anti-frost device
- Range of wired and wireless controls available
- Energy Saving Trust recommended
A regular system might have three significant component parts i.e. boiler, water tank and cylinder, but it is still a very cost-effective solution for your heating and hot water requirements.
The cost of installation is an important factor to consider when you’re budgeting. If you’re replacing an older, traditional boiler then a new Ariston regular boiler will still need similar pipework to connect the three elements. This simplifies things significantly for the engineer and should therefore be more cost effective than changing to another completely different heating system.

Ariston 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. For more detail about this brand’s warranty (including the small print) take a look at Ariston Warranties.
Ariston Boiler Repair Advice

To find out if there are any common problems associated with this manufacturer you can read our guide to Ariston Boiler Repairs & Common Ariston Boiler Problems.
Ariston Error Codes
Error codes may appear on your boiler’s display; it’s your boiler’s way of telling you that something is wrong. Each manufacturer uses a different coding system to help an engineer to diagnose a fault. In some cases it may be a simple issue such as low pressure which you can adjust yourself but more technical faults will certainly need a professional. We’ve put together a list of error codes for Ariston boilers to help you understand what’s wrong before you contact an engineer.
