THE BRIEFING
Dovegate was facing several challenges with their hot water system across the site. Their water heaters were outdated and unreliable, which was affecting daily operations. On top of that, the old pipework and insulation were causing energy losses and making the system less efficient. The project was driven by the need to modernise the setup, improve safety, and ensure everything ran more effectively.
The scope of works encompassed several areas of the site:
Venture and Assessment
- Removal of existing old water heater (Andrews 65/173 gas-fired) and replace with a new unit (Andrews HF48/300 gas-fired).
- Installation of a new temperature and relief valve.
- Modify the flue connection and water services pipework to fit the new water heater.
- Add insulation to the new pipework for increased energy efficiency.
- Perform electrical work and necessary testing.
Laundry
- Install a new Andrews HF48/300 gas-fired water heater to replace the old version.
- Installation of a new temperature and relief valve.
- Modify the flue connection and water services pipework to fit the new water heater.
- Add insulation to the new pipework.
- Perform electrical work and necessary testing.
Gate House
- Replace 2x existing old water heaters (Andrews 24/39 gas-fired) with new ones (Andrews 10/105 CLASSICflo gas-fired).
- Installation of new temperature and relief valves.
- Modify the flue connections and water services pipework to fit the new water heaters.
- Add insulation to the new pipework.
- Perform electrical work and necessary testing.
Facilities
- Replace 2x existing old water heaters (Andrews 24/39 gas-fired) with new ones (Andrews 10/105 CLASSICflo gas-fired).
- Installation of a new temperature and relief valves.
- Modify the flue connections and water services pipework to fit the new water heaters.
- Add insulation to the new pipework.
- Perform electrical work and necessary testing.
Endeavour and Avalon
- Replace 2x existing old water heaters (Andrews 65/173 gas-fired) with new models (Andrews HF48/300 gas-fired).
- Installation of new temperature and relief valves.
- Modify the flue connections and water services pipework to fit the new water heaters.
- Add insulation to the new pipework.
- Perform electrical work and necessary testing.
IN THE END
The project delivered a significant improvement to Dovegate’s hot water system, resolving the long-standing reliability and energy-efficiency issues. The old, inefficient water heaters were replaced with modern, high-performance units. This included the installation of new temperature and relief valves, modified flue connections, and upgraded pipework with proper insulation to minimise energy loss.
The electrical systems were fully tested to ensure safety and functionality, and the new setup was designed to be more energy-efficient, reliable, and robust. Daily operations, particularly in high-demand areas like the laundry and gatehouse, now run smoothly with consistent hot water supply. Overall, the modernised system not only meets current needs but is also better equipped to support the site in the future.
