Winter Maintenance - Hot Water Systems

At this time of year when the Winter chill is in full swing, the last thing you want is a hot water crisis for you and your residents. During Winter when demand for hot water is high, hot water systems are under stress due to maximum load capacity. It is important that they are performing to their full potential.

There are very simple maintenance activities that you can carry out yourself. Making simple observations and familiarising yourself with the plant room can help diagnose molehills before they turn into mountains. Not only will you save your body corporate and apartment owners significant dollars in increasing the longevity of your hot water plant room assets, it will also reduce running costs. You will have fewer hot water emergencies in the building and fewer headaches for you as the property manager.

For larger plant rooms we suggest paying a quick daily inspection. Observe the operation of expansion valves, pumps, power/gas supply, check valves, temperature and pressure relief valves. Look for any unusual changes in noise or appearance in their operation. 

Temperature and pressure relief valves are safety controls fitted to pressurised hot water systems. These valves ensure that the temperature of the water in a pressurised unvented water heater cannot exceed 99°C in the event that the normal heater thermostat controls fail. These valves guard against both over-temperature and over-pressure hazards wherever water is stored in unvented containers. This helps to increase the lifespan of the unit.

Check these valves are operational by discharging at monthly intervals, and replacing at no more than five year intervals. It is normal for a relief valve to have minor leaks during a heating cycle. However, if a valve is constantly leaking it may require replacing or further attention to the unit. A leaking relief valve wastes water as well as power by constantly drawing cold water into the system.
