ATAG Boiler Review & Prices

Heating engineer fitting a boiler

Are you in the market for a new Atag Boiler? We have reviewed and provided the prices below. 

ATAG has been designing and manufacturing boilers for almost 70 years. In that time, they claim to have set the highest standards for energy efficiency and engineering excellence across the world. ATAG design and manufacture a range of gas boilers including two types of combi boiler, a system boiler and a regular boiler, all in a variety of sizes.

Why choose an ATAG boiler?

ATAG boilers are built using high-quality stainless steel and brass components. ATAG boilers have been designed to include what ATAG call, their ‘revolutionary’ iCon heat exchanger which has unrivalled performance and efficiency levels.

The iCon heat exchanger is made from high-grade stainless steel and maintains 98% of its original efficiency levels throughout its lifetime. If you would like more information on what a heat exchanger does and how they work, we have a separate blog that discusses this in detail.

ATAG boilers have the lowest NOx emissions on the market, meaning that they are kinder to the environment than many other gas boilers. With this said, let’s have a look at what ATAG customers have to say about their ATAG boiler.

ATAG Reviews

ATAG has over 3.9k reviews on Trustpilot and a great score of 4.8 stars out of 5. In addition to this, 98% of ATAG’s boiler reviews are above average. 
The contrast in ATAG Trustpilot reviews supports our thoughts.

Here is what some of ATAG’s customers have to say about their ATAG boilers:

“First class boiler. Quiet, efficient and love the controls from my phone so can change the settings before I get home.”

“Had an ATAG boiler installed, really happy with this boiler, very quiet and efficient and reasonably priced. would recommend checking this out if you are considering buying a new boiler.”

“We have the IC Economiser + Combi. It was recommended to us by our regular service engineer of 20 yrs to replace our old boiler. Its been doing its job for 9 months now at the time of writing and we couldn’t be happier with it. It seems nice and compact and the hot water, in particular, seems better to us compared with our previous two boilers from more well known UK brands. The most noticeable thing I would say is how quiet it seems – a couple of times I’ve had to put my ear right up to the cupboard to check it was fired up. We decided to go for the smart controller (plus internet connection) in addition – a bit more expensive (maybe not for everyone) but it has made the overall system very simple to check up on and manage day to day.”

Once reading the comments above from ATAG customers, we can see that customers are more than satisfied with their ATAG boilers and recommend them as a reliable boiler manufacturer.

ATAG Combi Gas Boiler Ranges

A combi boiler combines a water heater and central heating into one single unit, removing the need for any additional hot water cylinders or cold water cisterns like you would need with a system or regular boiler. 

Moreover, combi boilers can also run on different fuels, meaning that they can also be installed in properties connected to the grid and off-grid homes. We have listed the different fuels that are compatible with a combi boiler below:

Natural gas

Natural gas is the most commonly installed boiler. The boiler is run on natural gas which is then supplied directly to the property from the mains.

Oil

Oil combi boiler is a popular choice of combi boiler for off-grid properties. However, you would need to accommodate an additional tank on the property to store the oil, which will need to be refilled by a supplier as it runs out.

LPG

LPG, meaning ‘Liquefied Petroleum Gas’, is an alternative fuel type for off-grid properties. LPG is produced during the extraction of natural gas and oil. Again, you will need to have an additional storage tank in your garden for this. Head over to our ‘LPG Explained‘ blog to learn what LPG is and how it works.

Electric

Electric boilers don’t burn fuel to produce hot water or central heating. Electric boilers help reduce climate change as a result of not producing carbon. However, the factories that produce electricity do create carbon, so electric boilers are not always as environmentally friendly as they first appear. Electrical boilers are not suitable for larger homes or homes with more than one bathroom as they can’t meet the demands for heating and hot water.

Hydrogen

Hydrogen is a completely new domestic fuel source, with water as its only by-product. When a boiler uses hydrogen as its fuel course, no carbon dioxide is produced, which makes it a good option when the target is zero carbon emissions.

Hydrogen is a renewable energy source, so unlike fossil fuels like gas and oil, hydrogen won’t run out. This also means that the price is likely to remain more stable as it won’t fluctuate with supply and demand as finite resources do.

With the current changes surrounding the Gas Boiler Ban, leading manufacturers such as Worcester Bosch, Vaillant and Viessmann have all created ‘hydrogen ready boilers’. A hydrogen-ready boiler is a system that can operate on natural gas and then be converted by a qualified engineer to operate safely and efficiently on hydrogen within an hour. Worcester Bosch has called for all boilers installed after 2025 to be hydrogen ready, so when/if the time comes to switch to hydrogen – the U.K will be ready.

What is a System Gas Boiler?

A system boiler can usually be found in homes that have a high requirement for hot water. They work by heating water in a separate storage tank from the boiler, usually found in an airing cupboard, this hot water is then available for use in multiple bathrooms should it be required.

In practice, you can have two baths running in separate bathrooms and they will both get hot water without affecting the heating of your home.

This differs from a combi in that a combi heats water directly from the mains supply and doesn’t store hot water, so you may struggle to run two baths simultaneously.

You may notice that the efficiency rating for all ATAG boilers is the same. With an ErP A-rating and an efficiency rating of 94%, ATAG boilers are one of the most efficient boilers on the market. 

In monetary terms, for every £1 you are spending on your energy bills, only 6p of the gases used are being wasted. This is a lot less than other, less efficient boilers, with ratings of 89%, for example. The lower your boilers efficiency rating, the more money that is being wasted. 

ATAG iS system boilers are highly energy-efficient and available in a range of outputs including 15kW, 18kW, 24kW, 32kW and 40kW. These outputs allow for small, medium and large homes to 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.

Regular boiler systems, also known as conventional, traditional, heat only or open vent boilers, are the most difficult to install or replace.

A regular boiler includes both a hot and cold water storage tank, the boiler itself and an expansion cistern located next to the cold water tank. This takes up quite a bit of space in a home and it’s usually preferable to switch to a combi so that these tanks can be removed.

Regular boilers are becoming less and less common as they are replaced with more efficient boiler systems that don’t take up as much space and have fewer parts, meaning, there is less to potentially go wrong.

Most likely, you would only tend to keep a regular boiler system if you were concerned that your central heating system would struggle to cope with the increased water pressure from a system or combi boiler.

ATAG iR regular boilers can be combined with ATAG’s iSteel hot water cylinders for maximum energy efficiency. ATAG also offer a wide range of flue options which means you can be flexible about where your boiler can be located.

ATAG produce the iR Regular boiler in a range of sizes to suit homes of every size and hot water demand including 15kW, 18kW, 24kW, 32kW and 40kW. 

What are the benefits of having an ATAG Regular boiler?

  • 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. 14 years with WarmZilla

ATAG Boiler Installation Costs

It’s a common misconception that you need to buy your boiler from whoever your energy supplier is. You don’t. 

Another common issue that confuses people about the cost of a new boiler is whether the price includes installation or not. Don’t get suckered in by low lead prices at wholesalers, yes, you can buy a new boiler for £699, but if it costs another £1,000 to get your boiler fitted then you may have got a better package all-in.

All WarmZilla boiler prices include Gas-Safe installation as standard. It also includes a system filter, system cleanse, guarantee, smart thermostat, and any other bits and bobs you need to get your boiler up and running. Not all prices include boiler installation, so make sure your quote does as you’ll be looking at an additional £500 – £1000 to get your boiler installed.

There are a lot of factors that contribute to what price you will pay to get a new boiler installed, including the size of your home, the number of radiators you have in your home, your wants and needs when it comes to demand for hot water, whether or not you need additional S or Y plans installed or if you want additional add-ons, including radiators and TRV’s or smart controls.

Alternatively, you can save yourself time and find a new boiler the WarmZilla way – where your price is fixed, everything is included and our online survey will work out exactly what boiler you need based on your answers to some simple questions.
