Product Description

The IS18 System gas boiler has been designed and manufactured by ATAG as a wall mounted unit. With compact dimensions of just 700x440x355mm (H x W x D) it should fit neatly into any home.

It delivers an impressive A rated efficiency of 89.8% which could help to save you money on your energy bills and reduce your home’s carbon footprint. The output rating of 18kW makes it best suited to smaller homes with not such a high demand for heating or hot water e.g. no more than one bathroom. This boiler is also available in a wide range of other outputs from 15kW to 40kW so there is a unit to suit most sizes of home.

As a System boiler it will produce hot water for your radiators and for your hot water storage cylinder such as the ATAG iSteel hot water tank. The in-built pump means the heat given out by the boiler is kept to a minimum to improve energy efficiency even further.

The unique iCon heat exchanger has a lifetime replacement guarantee and, with a 10 year warranty on the rest of the unit, you can rest assured that this boiler is a reliable investment for your home.

You even have the option of extending the warranty to 14 years which can be done by adding a Adey Atom filter, ONEZone smart controller and water treatment to the installation.
