System Boiler to Combi Boiler Conversions
A system boiler to combi boiler conversion, also known as a conventional to combi conversion, is an excellent upgrade for homeowners looking to improve efficiency, free up space, and enjoy a quieter, more hygienic heating system.
At JR Winters Ltd, we specialise in system boiler conversions to combination boilers, delivering safe, professional installations by trusted Gas Safe registered engineers.
What Is a System to Combi Boiler Conversion?
A system to combi conversion involves removing your existing system or conventional boiler, along with the hot water cylinder and any redundant pipework, and replacing it with a modern A-rated combi boiler.
This upgrade is ideal if:
You want instant hot water on demand
You’d like to remove the hot water cylinder and cold water storage tank
You want a quieter heating system, with no separate pumps required
You’re looking for a more hygienic hot water supply, as removing the cold water tank eliminates the risk of stored water contamination
You want improved efficiency and lower running costs

Most conventional to combi boiler conversions are completed within 1–2 days, depending on your property and existing pipework.
