Ensuring the seamless operation of your Gledhill StainlessLite Plus Horizontal system is crucial for uninterrupted hot water and heating. Here's a comprehensive guide to troubleshooting common issues:

Scale Build-up Solutions: Living in hard water areas poses the risk of scale accumulation in your system. Consider installing an in-line scale inhibitor to mitigate this issue. Additionally, lowering the temperature of stored water can help prevent scale formation. If you notice a significant drop in the recovery rate, it might indicate scaling problems. In such cases, follow the recommendations of a trusted Water Treatment Company for effective solutions.

General Troubleshooting Steps:

  • No Water Flow at the Tap: First, ensure that the mains water supply is activated. Check for blockages in the line strainer and verify that the combination valve allows water to flow in the correct direction.
  • Cold Water at the Tap: Confirm that the boiler is switched on and functioning correctly. Check for airlocks in the primary system. If issues persist, isolate the unit at the mains electric supply and inspect critical components like the cylinder thermostat, thermal cut-out, motorised valve, boiler thermostat, and boiler thermostat cut-out (if present). Remember never to bypass energy cut-outs under any circumstances.
  • If your units aren't heating and the heat source is electrical, isolate immersion heaters from the mains before resetting the energy cut-out. Contact us if you need replacement immersion heaters.

Addressing Relief Valve Discharge: If cold water discharges from the expansion relief valve, check the pressure on the expansion vessel when cold and recharge it if necessary. If the fault persists, examine the Pressure Reducing Valve or the Relief Valve. Replace faulty components with Gledhill approved replacements for optimal performance.

Commissioning Best Practices:

  • Always follow the commissioning procedure for draining down to maintain system integrity.
  • In the event of an overheat fault with hot water discharge, turn off the heat source while keeping the water supply intact.
  • After the system cools down, inspect thermostats and energy cut-outs in the boiler and immersion heaters. Replace any faulty components with units supplied by Gledhill to ensure optimal functionality before returning the system to full operation.

Addressing these common issues promptly is essential to ensure the efficient and safe operation of your Gledhill StainlessLite Plus Horizontal system. Remember, only qualified engineers should diagnose and repair any issues, following the manufacturer's guidelines and recommendations meticulously.
