Product Description

The Logic Plus is the ‘flagship’ range of boilers designed and manufactured by Ideal and the Logic Plus S15 system gas boiler is the best choice for smaller homes.

How efficient is the Logic Plus S15?

This is a condensing boiler that operates at highly efficient levels of 93%, which is why it has been awarded an ErP A-rating for heat. It has even been endorsed by the Energy Saving Trust.

Is the output rating suitable for my home?

A central heating output of 15 kW means that the S15 is best suited to smaller properties with around 10 radiators.

Are any other options available in the Logic Plus range?

The S15 has the lowest central heating output rating of all system boilers in the Logic Plus range. Larger outputs include 18 kW, 24 kW and 30 kW meaning there’s a suitable model for larger homes too.

Is a system boiler suitable for my home? A system boiler is the best option for homes with higher demands for domestic hot water that can’t be met by a combi. This is because a combi boiler heats water from the mains and delivers it directly to the tap. Meanwhile a system boiler stores the heated water in a cylinder, allowing for hot water to be delivered to more than a single tap at one time with strong pressure.

How long is the warranty period?

Logic Plus system boilers are covered by an extensive 7 year warranty while the heat exchanger has a 10 year warranty.

What are the key features of the Logic Plus S15?

Logic Plus boilers have a number of features, including boiler frost protection (beneficial for garage or loft installations), a large digital display, Quiet Mark accreditation and an LPG conversion kit is available for off-grid properties.

How big is the Logic Plus S15?

This boiler has been designed for a compact cupboard fit, thanks to dimensions of 700x395x278mm (HxWxD).
