HOW TO USE THIS GUIDE
When is a system boiler right for my home?
System boilers suit properties with multiple bathrooms, particularly where they are in use simultaneously, for example people showering in the morning. System boilers provide good hot water flow rates from a high performance cylinder. Many new build properties have system boilers with unvented hot water systems, replacing your boiler will be a straight swap. For those considering installing a system boiler in place of their combi boiler, this is worth while when you are extending and adding bathrooms. You will need to find a spot for the hot water tank and preferrably close to the bathrooms. For those with a conventional heat only boiler, you will need to change the boiler and the copper cylinder.
