hot water cylinder maintenance

A reliable hot water supply is an essential component of any modern household. Whether you use it for showering, washing dishes, or doing laundry, a well-maintained hot water cylinder is crucial for your daily comfort. Neglecting its maintenance can lead to costly repairs or even the need for a replacement.

1. Regular Visual Inspections:

Performing regular visual inspections of your hot water cylinder is the first step in identifying any potential issues. Visually examine the cylinder for signs of leaks, corrosion, or any physical damage. Look for wet spots, rust, or mineral deposits around the cylinder or the pressure relief valve. These can indicate leaks or problems with the system.

2. Temperature and Pressure Relief Valve

The temperature and pressure relief valve (TPR valve) is a critical safety feature of a hot water cylinder. It prevents excessive pressure build-up and overheating. To ensure its proper functioning, it is recommended to test the TPR valve periodically. Follow the manufacturer's instructions or seek professional assistance, as improper handling of the valve can be dangerous.

3. Insulation and Energy Efficiency

Proper insulation can significantly improve the energy efficiency of your hot water cylinder. Insulating your cylinder and the associated pipes can reduce heat loss, helping you save on energy bills. It is also recommended insulating hot water pipes, especially the first metre of the outlet and those exposed to colder areas, to prevent heat loss during distribution.

Regular maintenance of your hot water cylinder is crucial to ensure its efficient operation, prolong its lifespan, and prevent costly repairs. By performing visual inspections, testing the temperature and pressure relief valve, and improving insulation, you can maintain an optimal hot water supply in your home.
