What it is
The TSR thermostat is a cylinder thermostat supplied within the Popular Cylinder Spares range of cold water inlet controls. It is used on unvented hot water cylinders to sense stored water temperature and signal the heat source accordingly. It is listed as compatible with a wide spread of cylinder families, including Heatrae Sadia Megaflo Eco Plus, BOSS, MAIN, Potterton Gold, Everflo and Heatstore units.
Signs this part needs replacing
- Stored water temperature no longer matches the cylinder thermostat setting
- Cylinder water running consistently hot or cold regardless of the set point
- Boiler or heat source failing to shut down when the cylinder reaches temperature
- Intermittent hot water or fluctuating cylinder temperature during draw-off
- Visible damage, corrosion or a loose or broken capillary/connection at the thermostat
Before you order
- Confirm your cylinder manufacturer, model and capacity against the fit list above
- Check whether your cylinder is a direct, indirect or solar variant, as fitment differs between them
- Compare the markings on the existing thermostat with the TSR reference before ordering
- Check the cylinder's data badge or installation instructions if the model is not clearly identifiable
