Project overview
Timms Gas Services were instructed to carry out a complete boiler replacement and associated heating system upgrades at Eden Doctors Surgery in Hatfield Heath.
The surgery’s existing boiler was approximately 16 years old and had developed an internal leak, resulting in damage to the heat exchanger. Given the age and condition of the boiler, the client made the decision to invest in a new, modern heating system rather than undertake potentially costly repairs.
As a busy doctors surgery, having a reliable heating and hot water supply is essential to maintaining a comfortable, safe and operational environment for patients and staff.
Our objective was to deliver a reliable, energy-efficient heating solution, while upgrading the existing plant room pipework and associated components to support the long-term performance of the new installation.
The installation
Our engineers installed a new Vaillant ecoTEC plus 630, a high-efficiency condensing boiler designed to provide dependable heating performance.
Alongside the boiler replacement, we carried out extensive improvements to the existing heating infrastructure. Works completed included:
- Vaillant ecoTEC plus 630 boiler installation – replacing the ageing and internally leaking boiler with a modern, high-efficiency system.
- Horizontal flue installation – complete with a plume management kit to safely direct flue gases away from the building.
- 22mm Vaillant magnetic filter – installed to help protect the new boiler and heating system from circulating magnetic debris and sludge.
- Chemical power flush – the existing heating system was thoroughly power flushed using our Kamco CF90 machine to remove accumulated sludge, debris and contaminants.
- Complete plant room pipework renewal – all existing pipework feeding the boiler was cut out and replaced, including the heating flow and return pipework. All newly installed pipework was professionally lagged with insulation to minimise heat loss, improve energy efficiency and ensure a neat, high-quality finish throughout the plant room.
- Gas supply upgrade – the existing gas supply was upgraded and appropriately sleeved to accommodate the new installation.
The importance of power flushing
Before commissioning the new boiler, we carried out a comprehensive chemical power flush of the existing heating system using our professional Kamco CF90 power flushing machine.
Over time, heating systems can accumulate sludge, rust and other contaminants, which can restrict circulation, reduce heating efficiency and cause premature damage to boiler components.
By thoroughly cleaning the existing system before introducing the new boiler, we helped protect the installation, improve circulation and support its long-term efficiency and reliability.
The addition of the Vaillant magnetic filter provides ongoing protection by capturing magnetic debris circulating within the heating system.
The result
The project delivered a significant upgrade to the surgery’s heating infrastructure, replacing a deteriorating 16-year-old boiler with a modern Vaillant heating solution.
By renewing the plant room pipework, upgrading the gas supply and thoroughly cleaning the existing heating system, we addressed more than just the failed boiler.
The new installation provides the surgery with a more modern and dependable heating system, designed to support efficient operation and reduce the risk of unexpected breakdowns.
For a busy medical practice where heating and hot water are essential, investing in reliable equipment and professional installation offers valuable long-term peace of mind.
