ATAG Boiler Prices, Reviews & Warranties in the UK (2024)

 

ATAG Boilers

Welcome to Boiler Guide’s ATAG boiler review! ATAG has been designing and manufacturing boilers for nearly 70 years. Led by an ambitious research and development team in the Netherlands, the brand take great pride in the energy efficiency and reliability of their boilers.

In this ATAG boiler review, we’ll take you through all there is to know about the brand and its boiler products- from prices, to warranty, to repair advice.

ATAG manufacture multiple gas-fired combi, regular and system boilers with many also available in LPG for properties that aren’t connected to the gas network. When finding the right ATAG boiler for your home, you’ll need to compare the output rating, efficiency, warranty and potential price.

  • Output rating: It’s essential that your new boiler is of a suitable size to meet the heating and hot water demands of your home. Boiler size is displayed as an output rating, measured in kilowatts (kW), and, simply put, the higher the output rating the more powerful the boiler. ATAG boilers range from output ratings of 15 kW right up to 40 kW making them a great choice for almost any domestic property.
  • Efficiency: ATAG manufacture gas boilers, a fuel that produces waste gasses that must be emitted out of the property through a flue pipe. The boiler efficiency rating shows how much of the fuel is converted into usable energy for the central heating or domestic hot water. Modern ATAG boilers have an ErP Efficiency rating of 94%, making them highly efficient.
  • Warranty: All ATAG boilers are covered by a 10 year warranty as standard which will see that you’re well covered long after the installation.
  • Price: ATAG boiler prices in the UK are not publically available but you can typically expect to pay between £1,000 and £2,500 for a premium boiler. Throughout this page we have provided some ATAG boiler cost-estimates to give you an idea of what to expect.

All ATAG boilers can be found in our Boiler Comparison Tool. While the warranty is the same across all models, our tool is a great way to find a suitable output rating for your home. It’s also a good idea to include your existing boiler as part of the comparison.

If you’re unsure about how to find the perfect boiler for your home, don’t worry! Our network of professional heating engineers is here to help you make an informed decision. Getting a professional’s help will eliminate the risk of getting a boiler not suited for your home.

The first step is letting the boiler engineer know your heating demands, then they’ll be able to offer you a tailored boiler quote. But don’t stop there! To ensure you find the best boiler installer for your budget, it’s important to compare multiple quotes from different professionals.

Compare ATAG regular boiler prices, efficiency and warranty

Regular boilers are best suited to homes that already have the suitable pipework in place which is most likely to be in older properties. In addition to the boiler, a heating system that includes a regular boiler also needs a cold water storage tank in the loft, expansion vessel and a hot water cylinder. As ATAG regular boiler models have outputs ranging from 15 kW up to 40 kW they can suit small, medium and large homes.

ATAG combi boiler review: Pros & cons

Atag IC Economiser 39 Combi Gas Boiler

In an ATAG combi boiler review, it’s worth noting that ATAG offers two distinct Combi boilers: the iC Combination boiler and the iC Economiser Combination boiler. The iC Combination boiler stands out as a compact and exceptionally energy-efficient model, available in various sizes to cater to homes of different dimensions.

  • 40kW: 16.2 litres flow rate per minute. Suitable for large homes with more than one bathroom.
  • 36kW: 14.9 litres flow rate per minute. Suitable for medium to large homes with more than one bathroom.
  • 28kW: 11.5 litres flow rate per minute. Suitable for small and medium homes with one bathroom.
  • 24kW: 10.1 litres flow rate per minute. Suitable for flats or small homes with one bathroom.

The iC Economiser is ATAG’s most recent design which includes their patented Economiser; this technology recycles residual heat that would otherwise be lost as wasted energy and puts it to use, resulting in their most energy efficient boiler to date.

  • 39kW: 17.0 litres flow rate per minute. Suitable for large homes with more than one bathroom.
  • 35kW: 16.1 litres flow rate per minute. Suitable for medium to large homes with more than one bathroom.
  • 27kW: 12.6 litres flow rate per minute. Suitable for small to medium sized homes.

All ATAG iC combination boilers deliver hot water flow rates in litres per minute @ 35°C rise.

  • Compact size of 70 x 44 x 35.5cm makes ATAG combi boilers perfect for smaller homes
  • No need for a hot water cylinder results in more living space
  • No need for a cold water storage tank which frees up space in the loft
  • 94% ERP Seasonal Space Heating Energy Efficiency (A rated)
  • Less pipework makes installation typically cheaper and a reduced chance of frozen pipework
  • LPG conversion kit available
  • User friendly
  • 10 year warranty included as standard
  • Includes unique iCon heat exchanger with a lifetime replacement guarantee and weather compensator
  • Provides hot water on demand directly from the mains

Some slight downsides to the ATAG combi boiler range include:

  • While ATAG’s combi boilers are powerful enough to provide energy to larger homes, these will likely require more energy to run compared to a system boiler. This might result in higher energy bills.
  • There are some more affordable brands that offer similar combi boiler products in terms of size and efficiency

ATAG system boiler review: Pros & cons

A system boiler will heat your hot water for both your heating system and to be stored in a hot water storage cylinder for your taps and showers. The inclusion of the storage cylinder means you keep a backup of hot water which is perfect for homes with a high demand or multiple bathrooms. ATAG recommend their iSteel hot water cylinder for maximum energy efficiency.

ATAG iS system boilers are highly energy efficient and available in a range of outputs: 40kW, 32kW, 24kW, 18kW, 15kW. This means small, medium and large homes will find an appropriate model regardless of hot water demand.

ATAG claim that their system boilers have an edge over most competitors because of the in-built ErP pump. This provides more control over the heat produced by your boiler which improves the energy efficiency of the operation.

  • Compact size for easy installation 70 x 44 x 35.5cm
  • Suitable for homes with multiple bathrooms
  • Hot water supplied evenly to all taps at the same time
  • No risk of pipes or tanks in the loft leaking or freezing
  • Energy efficient for lower fuel bills
  • Built-in components makes installation quicker and neater
  • 10-year warranty included as standard
  • LPG convertible
  • Solar compatible
  • A rated energy efficiency 94%
  • Includes unique iCon heat exchanger with a lifetime replacement guarantee
  • Compatible with the ATAG ONE controller and 3 port valve kit
  • User friendly controls

Some downsides to an ATAG system boiler include:

  • You might have to allow time for the hot water to reach the desired temperature before using it
  • Hot water can become depleted if there are multiple outlets being used at once
  • Some extra home space will be taken up by the external hot water cylinder

ATAG regular boiler review: Pros & cons

Rather than replacing an entire heating system, you may choose to simply update your Regular boiler with a condensing and highly energy-efficient model. This means you will keep the cold water tank in your loft and hot water storage cylinder. iR Regular boilers can be combined with ATAG’s iSteel hot water cylinders for maximum energy efficiency.

ATAG produce the iR Regular boiler in a range of sizes to suit homes of every size and hot water demand: 40kW, 32kW, 24kW, 18kW, 15kW. They offer a wide range of flue options which means you can be flexible about where the boiler is sited.

  • Easily meets a high hot water demand
  • Ideal for homes with two or more bathrooms
  • Ideal for installation in areas where mains water pressure is low
  • Compact size and multiple flue options for flexible installation
  • Straightforward replacement for existing regular systems
  • 10-year warranty included as standard
  • Includes the unique iCon heat exchanger with a lifetime replacement guarantee
  • Completely user-friendly
  • 94% A rated energy efficiency
  • Solar compatible
  • LPG convertible

Some potential downsides to ATAG regular boilers might be:

  • The space required for the boiler, hot water cylinder, and cold water tank can be inconvenient, especially in smaller residences or apartments
  • Hot water tends to take longer to be delivered through your central heating system

To maximise these benefits, it’s important that your boiler is installed by a professional heating engineer with updated certifications and training. Otherwise, you risk not getting the full benefits of a new boiler and having your boiler break down faster.
