Product Description

The Logic Plus S18 is part of Ideal’s flagship range of system boilers and this model is particularly well suited to smaller homes.

How efficient is the Ideal Logic Plus S18?

This boiler has been endorsed by the Energy Saving Trust and also achieves an ErP A-rating for heat thanks to its highly efficient performance of 93%. This level of efficiency will see that very little fuel is wasted which could help to lower your energy bills.

Is the output rating suitable for my home?

The central heating output of 18 kW is best suited to properties with around 10 radiators.

Are any other options available in the Logic Plus range?

Alongside the S18 are three other system boilers in the Logic Plus range. For lower heating demands, the S15 has an output of 15 kW while the S24 and S30 can meet higher demands for central heating thanks to outputs of 24 kW and 30 kW.

Is a system boiler suitable for my home?

Heating systems that include a system boiler are made up of a boiler and a hot water cylinder. This means that you will need additional space around your home to accommodate both parts. The benefit of having a hot water cylinder is that it will be able to meet higher demands for domestic hot water and deliver a strong pressure to more than one outlet at a time.

How long is the warranty period?

In the unlikely event that a fault should develop, Logic Plus system boilers are covered by an extensive 7 year warranty. The heat exchanger has a separate warranty of 10 years.

What are the key features of the Logic Plus S18?

The Logic Plus S18 has a number of features which allow it to deliver reliable performance, including boiler frost protection (particularly beneficial for garage or loft installations), a large digital display, quiet operation and an LPG conversion kit is available for off-grid properties.

How big is the Logic Plus S18?

Thanks to dimensions of 700x395x278mm (HxWxD) the Logic Plus S18 can be installed within a standard kitchen cupboard.
