With an output rating of 15kW, the Ideal Logic Plus S15 is the least powerful system boiler in its range, however, don’t let this put you off, as this boiler is perfect for smaller homes with up to 10 radiators. However, if your home requires a higher demand for central heating, Ideal have designed the Logic Plus S18, S24, and the S30 for homes that need a larger energy output.
A system boiler is the best option for homes with higher demands for domestic hot water. This is because they store the water that is heated in a hot water tank so that it's ready whenever it's needed so that you have water ‘on tap’ (excuse the pun).
However, it is important to note that when purchasing a new or replacement system boiler, you will need to have the room in your home for an additional hot water storage cylinder. These are usually installed in an airing cupboard or similar size space in your home. For this reason, system boilers are not ideal for homes with limited space.
