Types of boilers
Combination (combi) boilers deliver both central heating and instantaneous hot water without the need for a hot water cylinder. Modern combi boilers can now meet the demands of more than one bathroom. Thanks to our engineering excellence, our models can help you save up to £320 a year off your gas bill (Energy Saving Trust, April 2017).
System boilers are traditionally fitted with an unvented hot water cylinder which provides an increased capacity of hot water. The fact that the pump and controls are contained within the boiler casing counts towards a simple and space saving solution. With an ATAG iS, not only are you selecting one of the most energy efficient boilers in Europe, but you’ll love its easy-to-operate simplicity too.
Also known as conventional boilers that are fitted in many UK homes. Regular boilers offer a simple and straight forward boiler replacement solution that traditionally requires a loft space to house the feed and expansion tank. Regular boilers come in a wide range of sizes.
