Excitingly, there’s an update for Hot Water Cylinders, presenting a permanent solution to cease the incessant drip of Cold Water Expansion valves.

Cold water expansion valves discharge around 4.5 liters of water a day to the drain. Expansion vessels are able to manage the effects of thermal expansion within a storage water heating system without discharging treated drinking water down the drain. This will reduce the amount of water used by the system.

Considering the continuous increase in water expenses, especially in cities such as Auckland, it’s prudent to consider investing in an expansion tank. This investment can effectively minimize water discharge, leading to savings not only on water bills but also on valve maintenance costs. Take the step to upgrade to an expansion tank by scheduling your appointment with Hot Water Cylinders NZ today.

An expansion tank is not merely an additional component but rather a crucial enhancement to your hot water cylinder system. By incorporating an expansion tank, you’re not only addressing the issue of water wastage but also ensuring the longevity and efficiency of your entire water heating setup. Let’s delve deeper into why investing in an expansion tank is a wise decision.

First and foremost, let’s address the persistent problem of water loss caused by cold water expansion valves (CWE). These valves are essential for regulating the pressure within the hot water cylinder by allowing excess water to escape when it expands due to heating. However, the continuous dripping of water from these valves can lead to significant wastage over time. An expansion tank offers a solution by providing a designated space for the expanded water to accumulate, eliminating the need for constant discharge into the drain.

Moreover, the installation of an expansion tank serves to mitigate the financial burden associated with escalating water expenses. As mentioned earlier, cities like Auckland are witnessing a steady rise in water costs, making it imperative for residents to adopt measures that promote water conservation. By reducing water discharge through the use of an expansion tank, you’re not only contributing to environmental sustainability but also saving money on your utility bills in the long run.

Additionally, let’s consider the impact of continuous water discharge on the maintenance of hot water cylinder valves. The incessant dripping can lead to wear and tear, necessitating frequent repairs or replacements, which can incur additional costs. By investing in an expansion tank, you’re effectively reducing the workload on the valves, thereby extending their lifespan and minimizing maintenance requirements.

Furthermore, it’s essential to highlight the role of expansion vessels in managing thermal expansion within a water heating system. These vessels help alleviate pressure buildup caused by fluctuations in temperature, ensuring the smooth operation of the entire setup. By integrating an expansion tank into your hot water cylinder installation, you’re enhancing its overall efficiency and reliability.

In summary, the decision to upgrade to an expansion tank is not only a proactive step towards conserving water and reducing utility expenses but also a strategic investment in the longevity and performance of your hot water cylinder system. Don’t wait until water wastage becomes a costly issue – take action now by scheduling your appointment with Hot Water Cylinders NZ and experience the benefits of a comprehensive water heating solution.

Manual vs Auto-Reset Cylinder Thermostats

Cylinder thermostats are energy-saving, safety devices. They control the heating element of your hot water cylinder by measuring the temperature of the water inside and switching the heat supply on and off to ensure water temperature stays within the acceptable range.

If the water temperature falls below the required minimum temperature, the heat supply (boiler or electricity) will start up. The New Zealand Building Code requires the minimum temperature inside a hot water tank to be 65oC. This is hot enough to inhibit the growth of harmful bacteria like Legionella. Once the desired temperature is reached, the thermostat will turn off the heat supply again.

On the other hand, if the temperature exceeds the maximum setpoint, the cylinder thermostat will switch off the heat supply to avoid unnecessarily overheating your water. This saves a lot of energy and obviously money on your energy bills.

As the water in the tank sits unused, it will start to lose some heat. If the temperature drops below the low limit, the thermostat will kick in to reheat the water and maintain the temperature.

Some hot water tanks will have either a manual or an auto-reset thermostat. So what’s the difference?

Manual-reset thermostat

Standard domestic electric water heaters’ control circuit consists of a manual-reset high limit switch, a lower thermostat, an upper thermostat, two heating elements and wires.

The upper element is energized when power is initially turned on to the unit. This heats the water in the upper third of the hot water tank, where hot water is drawn when you open a tap inside the house. When the desired temperature is reached in the upper third of the tank, power is switched to the lower heating element which continues to heat the water in the lower part of the tank until the lower thermostat setting is reached.

If the temperature inside the tank reaches 85oC (170oC), the high limit switch will be tripped. To ensure the over-temperature and energy cutout is set, you need to press the ‘reset’ button on the thermostat. See samples below:


Auto-Reset Thermostat

Just as the name suggests, an auto-reset thermostat has the capability to reset itself.

This is often offered as an upgrade feature for solar and hot water heat pump applications. Generally, solar water heaters generate tons of heat and have a tendency to heat water beyond the thermostat settings. This would result in frequent tripping of the high-limit switch, hence the need for an auto-reset thermostat.

Manual-reset thermostats may be used in split solar hot water systems, but it would need replacing every few years.

Some modern hot water cylinders also provide auto-reset thermostats as an option, allowing the water to remain within the ideal temperature range without any intervention.

The ‘reset’ button

The thermostat isn’t the only part of your electric water heater that can trip the reset button. If you are finding yourself having to reset the water heater too often or if you run out of hot water frequently, one of the following might be to blame:

  • Loose wiring. A loose wire in the heating element cause excess heat that will activate the high-limit switch.
  • Faulty high limit switch. If this device starts malfunctioning and consequently overheats the water, the switch will trip.
  • A short in the heating element. The thermostat may still work if there’s a short in the heating element, but the water will continue to be heated beyond the recommended temperature and trip the high-limit switch.
  • The problem may also be the electrical setup in your home.

If you suspect any of these, you should get a professional in to inspect your water heater.

More information about thermostats

If your hot water cylinder doesn’t have a thermostat or has a faulty one, do not attempt to install or replace it yourself. This is a job for a licensed and qualified tradesperson. There are electrical wiring and plumbing regulations and standards that must be followed. Also, it can be dangerous to an untrained person. Be sure to have the minimum limit set to 65oC to disinfect your water supply of harmful bacteria.

Please remember that setting the thermostat to a higher setting does not make the water heat up faster. Your heating system is designed to heat up water at a predefined rate, and raising the setting too high will simply result in wasted energy and even risks of scalding.

Since a temperature of 65oC may be too hot for most people, it is advisable to install a thermostatic mixing valve. This device mixes hot and cold water so you will get the right temperature from your taps and showers.
