ATAG Heating Technology UK

ATAG Heating Technology UK and its boiler range

ATAG Heating Technology UK Ltd. is the British arm of a heating technology brand that sells domestic boilers, hot water cylinders, controls and thermostats, and lists heat pumps as a forthcoming addition to its catalogue. The company does not present itself as a direct installer: it distributes its equipment and channels customers towards a network of ATAG Partner Installers, who must be Gas Safe registered.

The range is organised around four boiler families, each aimed at a different type of home and installation. The iC Economiser is the flagship combi model and incorporates heat recovery technology designed to reuse energy that would otherwise be lost. The standard iC Combi is presented as a space-saving option because it needs no cylinder, while the iS System is positioned for larger homes and the iR Regular as an upgrade path with minimal disruption. The iR range is also described as offering extensive flue solutions, allowing the appliance to be sited in various positions within a property.

Efficiency, noise and durability claims

The manufacturer states that its boilers are built to last with near-zero efficiency loss and describes the iS system boiler as one of the most energy efficient models available in Europe. The Economiser has received the Quiet Mark award for low noise in operation, a point the company highlights prominently. On running costs, ATAG cites a saving of up to £500 per year on fuel bills when its Economiser is compared with a leading competitor combi boiler, a figure it attributes to moneyhelper.org.uk.

Warranty and after-sales support

ATAG backs its boilers with an 18-year warranty, a term it markets as industry leading and which is subject to the company's terms and conditions. Alongside the warranty, the support section of the site gathers a support hub, troubleshooting guidance, FAQs and product manuals, so that owners and installers can locate documentation for their equipment.

Customer contact is handled by telephone and email, and the company also provides a contact form for enquiries about boilers, support or general questions. An annual service carried out by the company's experts is offered as part of the aftercare proposition.

Controls, cylinders and connected heating

Beyond boilers, ATAG supplies a set of controls intended to let households manage heating and hot water. The ONE Zone is a smart heating control presented as a way to reduce home energy bills, and it can be adjusted remotely through an app. The Cube controller is a programmable digital thermostat described as straightforward and reliable, while the programmable room thermostat follows a more classic design with flexible seven-day scheduling. The company also lists an ATAG Room Thermostat and a TADO v3 model among its control options.

For system and regular boiler installations, ATAG offers the iSteel cylinder range, designed to keep hot water available for longer. The company additionally flags that its products are future proofed as "Hydrogen Blend Ready".

Choosing a boiler and getting a quote

The website includes a boiler finder that walks a household through a series of questions: the reason for replacing the boiler, the type of property, the number of bedrooms and bathrooms, the existing boiler type and whether there is room for a cylinder. On that basis it recommends one of the four families, such as the iR Regular, iC Combi, iS System or Economiser, and then asks for a postcode to request a free quote from a local ATAG registered installer. The company states that quote requests receive a response within 48 hours.

ATAG also runs a campaign against illegal gas work, reflecting its insistence that installation be carried out by Gas Safe registered engineers.

Company addresses

The operational address is at 1 Masterton Park, South Castle Drive, Dunfermline, KY11 8NX. A separate registered address is listed at Suite 177, 80 Churchill Square Business Centre, Kings Hill, West Malling, ME19 4YU.
