We specialise in helping homeowners upgrade outdated or inefficient heating systems with reliable, modern alternatives.
One of our recent projects involved an internal to external boiler change for a customer based in Gaunts Common, a rural village just outside Wimborne.
Their old internal oil boiler had become unreliable and was ultimately beyond repair, so the most practical solution was to install a modern external alternative. The results brought improved efficiency, quieter operation, and total peace of mind.
About This Project
Our customer contacted us after their ageing internal boiler failed and could no longer be repaired cost‑effectively. Older oil boilers often suffer from corrosion, poor efficiency, and increasingly expensive breakdowns — especially when parts become difficult to source.
After assessing the property and discussing the client’s needs, we recommended installing a Worcester Bosch Greenstar Heatslave II External boiler. This model is designed specifically for outdoor installation and is ideal for freeing up indoor space while providing reliable, efficient heating.
The project included:
- Safe disconnection and removal of the faulty internal oil boiler
- Preparation of an outdoor base for the new boiler location
- Installation of the Worcester Bosch Greenstar Heatslave II External system
- Connecting the oil supply, heating system, and controls
- Full testing and commissioning to ensure peak performance
The homeowner now benefits from:
- A quieter home, thanks to the boiler being placed outside
- Improved efficiency and lower running costs
- Extra indoor space where the old boiler once sat
- A 7‑year Worcester Bosch guarantee for complete reassurance
