Product Description

The Logic Max S18 by Ideal is an industry-leading system gas boiler that’s best suited to homes with around 10 radiators.

How efficient is the Logic Max S18?

Efficient performance is one of the biggest benefits of this boiler as it could help to lower your energy bills. This can be seen from the 93% efficiency and ErP A-rating for heat.

Is the output rating suitable for my home?

Thanks to a central heating output of 18 kW, the Logic Max S18 is best suited to small to medium-sized homes with up to 10 radiators and a single bathroom.

Are any other options available in this range?

Ideal have included 4 system boilers in the Logic Max range covering a range of outputs, meaning that whether your home has a high or low demand for heating and hot water, there’s likely to be a boiler for you. The S15 has a lower output of 15 kW, while the S24 and S30 have higher outputs of 24.2 kW and 30.3 kW.

Is a system boiler suitable for my home?

If the hot water demands of your home are higher than can be met by a combi boiler then a system boiler is the best alternative. They heat water before storing it in a hot water cylinder, meaning that it’s ready to be delivered to more than one outlet at time. You will need space in your property for the cylinder in addition to the boiler.

How long is the warranty period?

An extensive 10 year warranty is available as standard when having the Logic Max S18 installed.

What are the key features of the Logic Max S18?

Housed in a scratched resistant casing, the Logic Max is well protected and for good reason as there are a number of beneficial features. Some of the features include a large digital display, full compatibility with Ideal heating controls, boiler frost protection, low lift weight (26.1kg) and reachable pressure gauge.

How big is the Logic Max S18?

The Logic Max S18 is ideal for compact installation within a standard kitchen cupboard thanks to dimensions of 700x395x278mm (HxWxD).
