ATAG i18R 18kW Regular Boiler
The ATAG i18R is a compact and wall-mountable regular gas boiler. This boiler has a 94% efficiency rating which means it will save you money on your energy bills (depending on your current boiler efficiency rating.)
With an output of 17.5kW, this boiler is ideal for homes with up to 10 radiators and a single bathroom. If your home has a higher demand for central heating and hot water, the ATAG i regular range has kW outputs of 24kW, 32kW and 40kW. So there is an option for everyone.
Although this boiler unit is compact and lightweight, you’ll also need a cold water tank and a feed installed alongside your regular boiler. This is because regular boilers are fed with cold water. The water is stored in a cold water tank in your attic, this water is then heated and stored in a hot water cylinder, ready to be sent to your radiators and taps.
For this reason, regular boilers are not recommended for homes with limited space.
