Introduction: How to prepare your hot water system for extreme weather

As extreme weather events increase, it’s vital to prepare your hot water system for efficient operation. Safeguarding your system with key measures can reduce the likelihood of expensive repairs or replacements.

This guide details crucial preventative steps for Castle Hill residents, including insulating tanks, adjusting temperatures, servicing tankless units, and emergency measures for extreme temperatures and outages.

Implementing these measures before cold weather sets in will not only enhance your system’s longevity but also optimise performance and reduce energy costs. Read on for critical steps anyone with a storage, solar hot water, or tankless system should take before the next cold snap or heatwave hits.

Insulate Hot Water Tanks and Pipes

Insulating your hot water tank and pipes is crucial to reduce heat loss, especially in extreme weather. Up to 75% of a system’s heat can be lost without insulation.

To insulate your storage tank and pipes:

  • Purchase fibreglass or foam insulation from a hardware store. Ensure it has an R-value equal to or greater than R-8.
  • Cut insulation to fit snugly around the tank. Secure with tape or wire ties.
  • Slip pre-slit foam or fibreglass pipe insulation over exposed pipes. Seal seams with tape.
  • Insulate inlet, outlet and relief valve pipes.
  • For systems that go outside, enclose the entire unit and pipes in an insulated box.

Adequate insulation keeps water temperatures stable, enhances system resilience during extreme weather, minimises water loss, and can lower energy costs. Consider consulting with a plumber for advice on suitable insulation.

Set Proper Temperature for Season

Adjusting your hot water system’s temperature for seasonal shifts maintains efficiency and shields against strong winds. We recommend:

  • Storage tanks: set temperatures higher than 60°C in winter, 50°C in summer.
  • Continuous flow: 50°C year-round.

Reduced temperatures lighten the system’s load, cut energy expenses, and lower scalding hazards, thereby improving safety. Setting storage tanks to higher temperatures in colder weather kills bacteria, further protecting the system from the cold’s impact. Explore strategies to fine-tune your heater’s settings for health safety and efficiency, taking into account the external climate.

To adjust your temperature settings against exterior walls:

  • Storage tanks: Consult the owner’s manual. Make sure your thermostat dial is set accordingly.
  • Continuous flow: Systems have no thermostat. Contact a plumber to adjust internal control unit.

Proper temperature settings in your electric hot system optimise performance in extreme weather. Adjusting lower in summer and higher in winter can provide efficient heat for your water, cutting energy bills, which in some cases still provides sufficient hot water.

Perform Routine Maintenance

It’s important to perform routine maintenance on your water system to keep it functioning properly during colder weather. This preventative care can improve performance, efficiency and longevity.

We recommend the following key maintenance tasks at least annually:

  • Check your water supply lines, inlet and outlet pipes, valves, fittings and ensure your tank has no leaks. Repair any issues.
  • Check and cleanse the pressure relief mechanism within the temperature-pressure valve.
  • Test the relief valve by manually opening it to flush sediment. Ensure it’s correctly turned off after testing can keep your water pipes from freezing.
  • For storage hot water tanks, examine the sacrificial anode rod and replace it to maintain optimal temperature pressure if deteriorated.
  • Flush tankless water heaters to prevent scale buildup that can cause a restriction in your flow system.
  • Inspect the pilot light, gas fittings, and burners for corrosion or blockages if you have a gas hot water system, and be vigilant for signs of carbon monoxide.

Regular maintenance fortifies systems against failure during harsh winter conditions, testing and ensuring system resilience. Scheduling annual servicing enhances the system’s ability to maintain temperature during outages and ensures peak operation in emergencies.

Prevent and Manage Freezing Risks

Given Castle Hill’s susceptibility to harsh winters, storms, and occasional power outages, protecting your hot water system from frozen pipes is essential. While some heaters have built-in freeze protection, additional precautions are advised to adequately heat your system.

Key steps you can do to prepare your hot water system against freezing include:

  • Keep pipes and valves well-insulated, including inlet/outlet pipes, to avoid rapid heat loss.
  • Wrap relief valve and pipe insulation with plastic, which can help create an added barrier against the cold.
  • Ensure that basements, crawl spaces, and other unoccupied areas with plumbing are well insulated to retain heat and stabilise temperatures.
  • Seal any drafts allowing cold air to access pipes or units.
  • Keep a small drip or trickle of running water through the pipe from your hot water tap, which can help prevent pipes from freezing.
  • Consider installing heat tape on exposed pipes to prevent pipes freezing.

If away during the winter, secure your home by using the shutoff valve to cut the main water supply and drain pipes to safeguard your heater. Arrange for regular property checks to maintain a warm, safe environment.

Learn to gradually thaw frozen pipes using a hairdryer or space heater directed at the affected area. Never use an open flame. If unable to thaw, call your plumber immediately to employ water shutoff actions to prevent burst pipes.

Have Emergency Backup Plans

With extreme weather capable of knocking out power or causing system failures, it’s wise to have contingency plans in place. We recommend residents in regions like North Carolina or Castle Hill take the following key steps to protect their hot water unit during winter:

  • Keep our number (1300 349 338) handy to call if your hot water system’s power supply fails or pipes freeze/burst.
  • Consider a flood stop system or portable generator to automatically disconnect your unit’s power during outages.
  • Stock up on a Red Cross-recommended emergency supply kit, including bottled water, non-perishable items, blankets, extra batteries, and a flashlight.
  • Know how to manually operate the temperature-pressure relief valve so you can drain the tank if needed.
  • Ensure all your family members understand what to do and who to call if the hot water system fails and water can no longer be heated.

Contingency plans bolster your heater’s resilience, ensuring swift recovery and preventing property damage after storms. Act promptly to prepare for impending extreme weather.
