At Max Shutler Plumbing & Heating Ltd, we regularly help homeowners improve their heating efficiency and comfort with modern, reliable systems. One of our recent projects involved an oil combi boiler conversion from a full electric heating system – a major upgrade that delivered instant hot water, better performance, and long-term savings for our customer.
About This Project
Our client’s property was previously running on a full electric heating system, which was both costly to run and inefficient when it came to providing consistent heating and hot water. They wanted a more practical, reliable solution that would reduce their energy costs and provide on-demand hot water without relying so heavily on electricity.
After discussing the options, we recommended installing a Worcester Bosch Heatslave II External Oil Combi Boiler. This system is ideal for rural homes without access to mains gas, providing the benefits of a combi boiler while using oil as the main fuel source.
The installation process included:
- Installing a new external oil storage tank in a suitable location
- Running an oil feed pipe from the tank to the new boiler
- Installing the Worcester Bosch Heatslave II External Combi Boiler
- Connecting the new boiler to the home’s existing heating and hot water system
- Commissioning and testing the system for safe, efficient operation
The transformation was immediate. The customer now has instant hot water on demand and a cost-effective heating system that uses very little electricity compared to their previous setup. The new Worcester Bosch boiler also comes with a 7-year guarantee, offering complete peace of mind.
This oil combi boiler conversion has not only improved comfort but also dramatically reduced running costs – a huge benefit for rural homeowners still relying on electric heating.
