The Logic Max 18kW System Gas Boiler is a highly reliable boiler thats comes with a variety of features and benefits.
Designed and manufactured by Ideal, this condensing unit comes with an output rating of 18kW which makes it perfectly suitable for smaller homes with one bathroom that don’t have such a high demand for heating and hot water. In addition to this model are a range of other boilers with different outputs, including 15kW, 24kW and 30kW, meaning that there’s a suitable boiler for the heating demands of just about any home. The unit also features a high efficiency rating of 93%, giving it an ErP A rating.
The unit is housed in a scratch resistant and hard wearing case and thanks to its compact size, it’s able to fit into a compact cupboard to help you save valuable space around the home. Despite its compact size, there’s still room for lots of features. The Logic Max is fully compatible with Ideal controls, comes with a large digital display, an easy to reach pressure gauge on the front panel and a service timer that has a telephone number display to remind you when your boiler boiler needs a service.
This boiler is easy to install thanks to its low lift weight, which will help to save time and money with the installation. It’s also easy to commission and service so you’ll be saving time and money there too. As a System boiler, this unit directly heats your central heating system and hot water for a storage cylinder. Most of the important parts of the hot water and heating system, such as the pump and expansion vessel, are built into a System boiler which makes it quicker and cleaner to install. With a System boiler, you’ll be getting a faster response to demand for heating and hot water, plus you won’t need to have a feed and expansion tank in the loft.
Available with a 10 year warranty as standard, that can be extended to 12 years when installed by a Max Accredited installer, you’ll have the peace of mind that this boiler won’t let you down.
