Upgrading your heating system can make a significant difference to both efficiency and convenience—especially for rural properties relying on oil heating. We recently completed an Internal Oil Combi Boiler Conversion in Hampshire, helping a homeowner modernise their system by switching from a traditional oil boiler with a hot water cylinder to a more efficient and compact combi system.
This case study explores the project, the benefits of the Worcester Bosch Greenstar Heatslave II Internal Combi Boiler, and what to consider if you’re planning a similar upgrade.
About This Bathroom Internal Oil Combi Boiler Conversion
Our customer, based in Hampshire, had been using a conventional oil heating system for many years. Their setup included a separate boiler and hot water cylinder, taking up valuable space and operating at lower efficiency. They wanted a modern solution that would simplify their heating system, free up space, and reduce energy consumption.
We recommended a full internal oil combi boiler conversion, replacing the outdated system with a Worcester Bosch Greenstar Heatslave II Internal Combi Boiler. This involved:
- Safe removal of the existing oil boiler and hot water cylinder
- Upgrading and modifying the existing pipework to suit the new system
- Installing the new internal Greenstar Heatslave II
- Testing and commissioning the system to ensure optimal performance
By switching to a combi boiler, the customer now benefits from:
- Hot water on demand with no need for a storage cylinder
- Improved energy efficiency, reducing oil usage and heating bills
- More space in their home thanks to the removal of the water tank
- Peace of mind with an 8-year guarantee on their new boiler
