Common Questions About the Logic Max S24
What is a system boiler?
A system boiler heats water and stores it in a separate unvented cylinder. Unlike a combi, it can supply multiple bathrooms at mains pressure simultaneously.
Do I need to replace my cylinder when fitting the Logic Max S24?
If your current cylinder is old or conventional (vented), we'd typically recommend upgrading to an unvented cylinder to take full advantage of the system boiler.
Is 24 kW enough for a 5-bed house?
For central heating, yes. For larger families with very high hot water demand, the S30 or S35 may be a better fit.
