Understanding Your Hot Water System

Hot water is essential to modern living, whether for showers, dishwashing, or laundry. But how often do we pause to consider how that comforting warmth reaches our taps? Let’s dive into the intricacies of hot water systems.

At its core, a hot water system takes in cold water, heats it through an energy source, and then delivers it on demand or stores it for future use. The heart of this process is the heating mechanism, which can vary based on energy sources and system types.

Different Types of Hot Water Systems

  1. On-demand/Tankless Systems: These are becoming increasingly popular due to their energy efficiency. As the name suggests, tankless systems heat water directly without a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, where it’s instantly heated, providing a constant hot water supply.
  2. Storage Systems: Traditional storage water heaters involve large tanks where water is stored and continuously heated, ready for use. While they can deliver hot water quickly, they may waste energy by constantly heating the stored water, a phenomenon called “standby heat loss.”
  3. Heat Pump Systems: A more eco-friendly alternative, these don’t generate heat directly. Instead, they move heat from the air or ground to heat the water. They can be more energy-efficient than traditional electric water heaters, especially in warm climates.
  4. Solar Water Heaters: These use the sun’s energy to heat water stored in a tank for later use. While the initial installation can be costly, they can significantly reduce energy bills in the long run, especially in sun-rich regions.
  5. Hybrid Systems: These systems combine the features of different heating mechanisms. For example, a system might use solar energy primarily but switch to electricity during cloudy days.

The Electrician’s Perspective

Now, you might wonder, why would electricians be concerned about hot water systems? The connection is deeper than one might first assume.

Electricians are experts in all things related to electrical systems. And given that many hot water systems, especially on-demand and storage types, utilise electrical components, it’s within an electrician’s domain to ensure these parts function optimally and efficiently.

Why Electricians are Knowledgeable about Energy Efficiency

Electricians undergo rigorous training, not just in installing and repairing electrical systems but also in optimising their efficiency. They understand the intricacies of energy consumption, from the wattage of a bulb to the energy demands of a large water heater. This extensive knowledge enables them to recommend best practices and products to minimise energy waste and optimise performance.

Furthermore, as the world shifts towards more sustainable energy practices, electricians are often at the forefront of installing and maintaining green technologies, like solar panels or energy-efficient appliances. Their exposure to these technologies gives them insights into their practical benefits, making them invaluable advisors for homeowners looking to adopt more energy-efficient systems.

The Role of Electrical Components in Hot Water Systems:

Electric hot water systems, in particular, rely heavily on electrical components. These include:

  • Heating Elements: These are immersed in the water and, when powered, heat the surrounding water to the desired temperature.
  • Thermostats: These monitor the water’s temperature. The thermostat activates the heating element if it drops below a set point. Once the water reaches the desired temperature, the thermostat deactivates the element, ensuring consistent water temperature and preventing energy wastage.
  • Timers and Controllers: Advanced hot water systems might incorporate timers or smart controllers, allowing users to schedule when the system heats water, reducing energy consumption during off-peak hours.

Water heaters are workhorses in our homes, dutifully supplying hot water for showers, dishwashing, laundry, and more. Over time, however, this constant usage can take its toll. Regular maintenance is essential to ensure your water heater’s longevity and optimal performance. By following simple tasks such as flushing the tank, inspecting pressure valves, checking for leaks, and cleaning sediment buildup, you can save money on costly repairs and enjoy hot water whenever needed.

Why Maintenance Matters

Before diving into the nitty-gritty of maintenance, it’s important to understand why it matters. A well-maintained water heater operates more efficiently, uses less energy, lasts longer, and reduces the risk of inconvenient and potentially damaging leaks. Maintenance is a form of prevention; it’s a small investment of time and energy that pays off by preventing major issues and prolonging the life of your heater.

Water Heater Maintenance

Regular Flushing of the Tank

One of the most crucial steps in maintaining a water heater is to flush the tank regularly. Over time, minerals in your water can build up inside the tank, causing corrosion and reducing the unit’s efficiency. Flushing the tank is a relatively straightforward process that can make a significant difference in the performance of your heater.

To flush your tank:

  1. Start by turning off the power to the heater and closing the water supply valve.
  2. Attach a hose to the drain valve, ensuring the other end is directed towards a suitable drainage point.
  3. Open the drain valve and let the water flow until it runs clear, indicating that most sediment has been flushed out.
  4. Once done, close the drain valve, open the water supply, and turn the power back on.

Inspecting Pressure Relief Valves

The pressure relief valve is a critical safeguard in your water heater, designed to discharge surplus pressure from the tank. Malfunction of this component can result in a hazardous over-pressurization situation. To examine its performance, cautiously lift the valve’s lever and then allow it to snap back into place. The expected reaction is a distinct gurgling noise, indicating water being released into the drain pipe. Absence of this sound, or if water discharge persists after the lever is released, are red flags suggesting the valve is likely due for a replacement.

Checking for Leaks

Leaks are not just a nuisance but can indicate serious issues with your water heater. Check for signs of leaks regularly, such as pooling water around the base of the heater, dampness or rust on the tank, or an unusual increase in your water bill. If you find any leaks, you must call a professional immediately to prevent further damage.

Cleaning Sediment Buildup

Even with regular flushing, some sediment may still build up over time. This can reduce the efficiency of your heater and even cause damage. A clear sign of sediment buildup is a rumbling or banging sound when the heater is on. To clean the sediment, you may need to drain the tank completely and use a long, flexible brush to scrub the bottom. This task is quite involved and may require professional help, especially if you need to be more comfortable working with water heaters.

General Tips and Tricks

In addition to the above steps, a few general maintenance tips can keep your water heater in top shape. Keep the area around your water heater clear of debris and flammable materials. This can help prevent accidental fires and improve the efficiency of the unit.

Water Heater Maintenance

Regularly test the water temperature to ensure it’s not too high. A temperature of around 120-130°F is generally recommended. A higher temperature increases the risk of scalding and can cause excess wear and tear on the unit.

Final Thoughts

Maintaining a water heater is an essential part of homeownership. By taking the time to flush the tank, inspect the pressure relief valves, check for leaks, and clean sediment buildup, you can extend the life of your unit and enjoy hot water without interruption. While these tasks require time and effort, they are undoubtedly less costly and inconvenient than dealing with a broken water heater. Here’s to many more years of hot showers and clean dishes!…

Common Hot Water Plumbing Problems and How to Solve ThemCommon Hot Water Plumbing Problems and How to Solve Them

Hot water is indispensable in our daily lives, from enjoying a hot shower to washing dishes. However, hot water plumbing systems aren’t immune to problems that can disrupt our routines. 

This blog post will identify common hot water plumbing problems, explain their causes, and guide you on how to solve them. We’ll also discuss when to call in a professional plumber and preventative maintenance steps to prolong the lifespan of your system.

Water Heater Leaks

Leakage is a common issue that plagues many hot water systems. The causes can range from a loose drain valve, excess pressure buildup in the tank due to faulty temperature and pressure relief valve (T&P valve) to tank corrosion.

Hot Water Plumbing Problems

Solution: First, identify the leak source. If it’s the drain valve, tighten it. But don’t overdo it, as too much pressure could cause breakage. If the problem persists, you may need to replace the valve.

If it’s a faulty T&P valve or a corroded tank, these are more complex issues that a professional plumber should address. If you are in Queensland, we recommend

It’s worth noting that if your water heater tank is corroded, replacing the entire unit’s usually more cost-effective than repairing it.

Inadequate Hot Water Supply

There’s nothing more disappointing than a shower turning cold halfway through. This problem could be due to an undersized water heater, a faulty thermostat, or sediment buildup at the bottom of the tank.

Solution: If the issue is an undersized water heater, you may need to upgrade to a unit with a larger capacity. For a faulty thermostat, try adjusting it to a higher setting (between 120 – 140 degrees Fahrenheit is generally safe and efficient). If there’s no improvement, consider replacing the thermostat.

Sediment buildup can be addressed by flushing the water heater tank, a maintenance task we’ll discuss later in this post.

Strange Noises

Your water heater might sometimes produce unusual sounds – popping, cracking, or rumbling. Such noises are commonly caused by sediment accumulation within the tank, which leads to water boiling and the formation of steam bubbles that subsequently pop.

Solution: The most effective method to resolve this issue involves draining and flushing your water heater to eliminate the sediment. This task can be carried out by you personally, however, if you feel uneasy about it, you can enlist the assistance of a plumber.

Foul Odours

If your hot water smells bad, it could be due to bacteria growth in the water heater tank. This usually happens when the water heater is set at a low temperature (below 120 degrees Fahrenheit) for a long period, allowing bacteria to thrive.


  1. Increase the temperature to above 60C for a few hours to kill the bacteria.
  2. Follow this by flushing your water heater.
  3. Be cautious with the high-temperature setting to prevent scalding.

Regularly flushing your hot water system is a must for preventative maintenance. Over time, minerals and sediments from the water can accumulate at the bottom of your tank. Regular flushing helps remove these deposits, improving the efficiency and lifespan of your heater. You can undertake this task every six months to a year, depending on the hardness of your water.

Hot Water Plumbing Problems

Descaling is another maintenance procedure beneficial for those living in areas with hard water. Mineral deposits can accumulate inside the pipes, reducing water flow and efficiency. Descaling involves using a descaling solution to dissolve these mineral deposits.

Remember, regular maintenance is key to preventing most hot water plumbing problems. Nonetheless, when confronted with complicated problems or if uncertainty prevails, it’s always advisable to reach out to a professional plumber. With their training and experience, they can accurately diagnose and rectify the issue, saving you time and potential additional costs from errors.…

Using Energy Efficient Appliances in All ClimatesUsing Energy Efficient Appliances in All Climates

Heat pumps are operated by electricity, but unlike electric heaters, they are far more efficient. Instead of directly converting energy from power, heat pumps disperse heat that’s already there in the outdoor environment so that you don’t have to. They can also be used in conjunction with air conditioners and even with solar panels for a natural, environmentally-friendly way to cool your home.


The way that heat pumps work is by utilizing the natural exchange of heat between hot air and cold air. If you live in a cold climate, then you are more likely to experience heat loss during the summer months. This is because, in cooler climates, warm air cannot circulate as effectively. Because of this, it does not heat as quickly as it would in warmer climates. The speed at which heat pumps are most efficient in cooler climates is during the spring and fall months. During these months, they are most efficient, as they are taking advantage of natural exchange to heat the air.

In warmer climates, heat pumps are often used in conjunction with air conditioners. Air conditioners are designed to regulate the temperature inside of a building to keep it from becoming too hot or cold. They are also sometimes used in areas of high humidity to help lower indoor temperatures. While both of these types of cooling equipment are highly effective, heat pumps are sometimes used instead. Heat pumps are extremely efficient in all areas of a home, regardless of the climates present.


Before you consider any heat pump installation cost, you should take into consideration the total cost of a new furnace or boiler. A new furnace will probably cost substantially more than a simple heat pump upgrade. Even if you are willing to spend a little more on a new furnace or boiler, installing a heat pump is a good investment. If you have a conventional furnace that uses natural gas or propane gas as a fuel source, then you may want to look into getting a dual fuel system instead of just a heat pump upgrade.

Before You Install a Heat Pump

If you live in mild or moderate climates, you may not have many options. In areas where winters are cold and summers are hot, a heat pump is an excellent choice. It can keep your home at a comfortable temperature even in temperatures that are uncomfortable during the summer months. The best kinds of air-source heat pumps can heat an entire house even in extremely cold climates. These are often used in homes with high ceilings and many rooms that are off the floor or have low ceilings.

If you have a traditional furnace that uses oil, natural gas, or electricity to heat your home, then you need to make some upgrades to your existing furnace. Older furnaces are not able to keep up with the extreme demands that homes put on them. It would be necessary to replace the furnace, as well as all of your other heating systems. In most cases, upgrading a single unit to include both a gas furnace and an electric furnace is the most cost-effective way to heat your home.


One benefit of heat pumps is that they require very little maintenance after they are installed. Unlike furnaces, they run on electricity and do not burn fuel. For this reason, they do not contribute to pollution. If you have an air-source heat pump, then you can install it anywhere in your home. There are some things to keep in mind though. Your heat pump can only heat the space that it draws within, so if you want to heat your whole home, then you will need to have multiple units.…
