Understanding Hot Water Systems and Their Key Components
There are several main types of water heating systems used in homes - electric hot water systems, gas hot water, solar, and heat pump. Each system has unique components that collaborate to supply hot water efficiently via heating and delivery.
Electric hot water system uses one or more electric heating elements submerged in a storage tank to heat the water. The main components are the hot water tank, heating elements, thermostat to control temperature, pressure relief valve, and pipes to supply hot water.
Gas hot water system utilises a gas burner that heats a storage tank. Key parts include the storage tank, gas control valve and burner, flue pipe to vent exhaust, thermostat, pressure relief valve, and water pipes.
Solar hot water systems use solar thermal collectors to harness heat from the sun. This technology enables continuous flow of heated fluid in the collector, which then transfers heat into the water storage tank. Key components are the solar collectors, storage tank, electric booster heating element, pumps, and controllers.
Heat pump hot water systems work by extracting heat from surrounding air to warm refrigerant gas in a heat pump unit. This heat energy is then utilised by a water tank to heat water efficiently. Key parts are the heat pump unit, storage tank, thermostats, pressure valves, and pumps.
Understanding your system’s components and operations is key to effective maintenance. It also assists in diagnosing issues to determine if professional repairs are needed.
The Importance of Regular Maintenance
Regular preventive maintenance for your hot water system is crucial for multiple reasons. Catching minor problems early on through routine checks can help preserve the lifespan of your hot water system, avoiding inconvenient outages and costly repairs down the track.
Firstly, it helps prevent unexpected and costly breakdowns. Well-maintained units are more reliable, with increased lifespan and fewer leaks, faults and signs of wear.
Consistent maintenance can significantly extend your hot water system’s lifespan. The lifespan hot water units are subjected to annual servicing and component replacements as required can outlast units left unchecked for over a decade.
There are energy efficiency and cost benefits too. Well-maintained systems require less power for heating, thus cutting electricity or gas consumption. You save on energy bills while also reducing your environmental footprint.
Routine maintenance upholds safety standards and also improves the cost-efficiency of your home’s hot water system. Regular checks verify that components such as tempering valves, pressure relief valves, and the sacrificial anode are in good condition.
So whether optimising functionality, efficiency, costs, sustainability, or safety - diligent hot water system maintenance pays dividends across the board.
Recommended Maintenance Tasks and Schedules
To ensure optimal performance of your home’s hot water system, perform key maintenance tasks at least every five years.
Every 6 months:
- Inspect all water pipes, connections, and TPR valves for signs of leakage or malfunction
- Check the TPR valve by lifting the lever - a dysfunctional valve can cause water to not flow as expected
- For solar systems, ensure the glycol fluid levels in the solar collectors are adequate
Annually:
- Engage a professional to flush the tank with the drain valve, removing mineral sediment buildup.
- Test and record water temperature - should be 50-60°C
- Examine the anode rod, which should be replaced if eroded beyond 60%, typically every few years.
- Inspect the tempering valve to ensure safe hot water delivery
Every 3 years:
- Replace valves and components in your gas storage hot water systems
- Check electric heating elements and thermostats
- Inspect heat pump unit coils and pumps
Consider upgrading to a new water heater every 8-12 years to maintain optimal efficiency and longevity. Keep maintenance logs to ensure the hot water your appliances rely on comes from a well-serviced system.
Alongside basic DIY upkeep, annual professional servicing is key to maintaining your system’s safety and efficiency.
Detecting Issues and Signs of Needed Repairs
Early detection of issues can prevent more significant problems in the future. Be vigilant for any signs that your hot water system needs maintenance or repairs:
- Irregular temperatures of the water your system produces - If temperatures fluctuate or are too hot/cold, the thermostat or heating elements may be faulty.
- Water quality issues - Rusty, brown, or muddy water indicates corroded pipes or a failing tank lining.
- Low water pressure may indicate sediment buildup, leaks, or pressure valve issues.
- Strange noises - Clunking, banging, or rumbling noises can indicate problems with valves or heating elements.
- Wet patches or water leak - Leaks around the tank, valves, or pipe joints often require resealing or replacement.
- Fault error codes - Many systems will flash numerical fault codes on digital displays when potential issues are detected.
We recommend seeking professional servicing if you notice any of the above issues. Left unchecked, problems can worsen over time leading to system failure, costly parts replacements, and even water damage if significant leaks eventuate.
Annual servicing can identify and address minor issues before they lead to breakdowns. For example, Inspections can uncover issues like corroded connections that require resealing well before leaks develop.
Don’t take chances with your hot water system - consistent maintenance safeguards efficiency and prevents avoidable, expensive repairs.
Considerations for DIY vs Professional Maintenance
When it comes to hot water system maintenance, homeowners have a choice between DIY servicing or hiring a professional plumber. Both approaches offer distinct advantages.
Basic tasks such as leak inspections, valve testing, temperature monitoring, and sediment flushing are manageable for the DIY homeowner. DIY is often cheaper too. You just cover the cost of parts.
However, some aspects of gas water service require qualified expertise. Checking electric heating elements, testing thermostats, inspecting solar panels, and evaluating system efficiency are best left to licenced plumbers with technical know-how.
Licensed plumbers also have the tools, equipment, and materials for comprehensive servicing. Tasks like replacing anodes, fixing leaks, or adjusting thermostats are difficult without proper gear. Calling in a tradesman also safeguards warranty coverage should faults arise down the track.
