Ideal Logic Max S18 System Boiler

With an output rating of 18kW for central heating, this model is great for smaller homes with up to 10 radiators and a single bathroom. The Ideal Logic Max S18 is middle of the range when it comes to energy output, therefore, if you are looking for a more powerful system boiler, the S24 or S30 may be better suited to you and your home. Meanwhile, if you’re home doesn’t require as much power, the S15 is also available.

A system boiler is a great choice for homes with a higher demand for domestic hot water than can be met by a combi boiler. This is because a system boiler stores the hot water that is heated in the boiler unit in a separate cylinder, ready for use when needed.

Although the boiler unit itself is compact and lightweight, it is important to note that when purchasing a new or replacement system boiler, you will need to consider space for an additional hot water cylinder. This is usually installed in an airing cupboard.
