How to Identify Hot Water Faults

Hot water is an essential part of our daily routine, and we often take it for granted until something goes wrong. If you’re experiencing issues with your hot water cylinder, don’t worry; there are usually straightforward solutions to fix the problem. In this article, we’ll explore some common hot water faults and how to identify them.

Instant Hot Water Heaters

Instant hot water heaters are a popular choice for many households as they provide hot water on demand. However, they can also experience faults that can disrupt your hot water supply. Here are some common issues to check for:

  • No power to the unit: If your instant hot water heater has no power, it won’t be able to produce hot water. Check that the unit is plugged in and that there is the power to the socket.
  • Reduced water flows: If you’re experiencing reduced water flow, this could be due to blockages in the diffusers or in-line strainers. Clean these out to improve water flow.
  • Run out of gas: If you’re using LPG gas, check if you’ve run out. If so, replace the cylinder to restore your hot water supply.

Gas Cylinders

Gas cylinders are another popular option for heating hot water. However, there are some common faults that you should check for:

  • Pilot flame is blown out: If the pilot flame has blown out, relight it according to the manufacturer’s instructions.
  • Water leaking onto the burner or pilot flame: If water is leaking onto the burner or pilot flame, this can cause it to go out. Check for any leaks and repair them if necessary.
  • Gas meter shut off: If the gas meter has been shut off, your hot water cylinder won’t be able to produce hot water. Check that the meter is on and functioning correctly.

Electric Hot Water Cylinders

Electric hot water cylinders are a reliable option for heating water, but they can also experience faults. Here’s what to check for:

  • Element: If the element has failed, the hot water cylinder won’t be able to heat the water. Check for any signs of damage or wear and replace them if necessary.
  • Thermostat: If the thermostat isn’t working correctly, it can cause the hot water cylinder to overheat or not heat the water at all. Check the temperature settings and replace the thermostat if necessary.
  • Fuse: If the fuse has blown, the hot water cylinder won’t be able to function correctly. Replace the fuse with a new one.
  • Strainers: Check the strainers for any blockages, as this can affect the flow of hot water.

Renovation Work

If you’ve recently had any renovation work done in your home, this could cause your hot water faults. Check that all pipes and connections are secure and that no damage has been done to the hot water cylinder during the renovation work.

Conclusion

In conclusion, identifying hot water faults can be simple if you know what to look for. By checking these common issues, you can often diagnose and fix the problem without the need for a professional. However, if you’re unsure or unable to fix the fault, it’s always best to seek advice from qualified professionals such as Hot Water Cylinders NZ.

Best instant hot water systems: Which one is right for you?

Gas hot water systems can be a great option for homeowners looking for an efficient and convenient way to heat their water. One major benefit of a gas hot water system is that it provides instant hot water on demand, so you do not have to wait for a tank to fill up and heat the water.
This can save you time and make your daily routine more efficient. In addition to providing the best instant hot water, gas systems can be more cost-effective overall, as they often use less energy to heat water than electric systems. Finally, gas hot water systems can be a space-saving option, as they do not require a large storage tank to take up lots of room in or outside your house.

There are so many options, which one is right for me?

Choosing the right gas infinity unit for your house is important because getting the wrong size or type of unit can be costly. If you choose a unit that is too small, it may not be able to meet the hot water demand of your household, leading to a lack of hot water or low water pressure.
On the other hand, if you choose a unit that is too large, it may cost more to purchase and operate than necessary, resulting in higher energy bills. Therefore, it is important to accurately assess the hot water needs of your household and select a unit that is most appropriately sized for those needs.

For one-bathroom homes:


The Rheem 16L gas califont unit is a compact and efficient choice for providing hot water in a small home or apartment. It is designed to support up to two people and is ideal for a single-bathroom home. With its 16-liter capacity, it can provide enough hot water for basic household needs such as showering and washing dishes but may not be able to support more demanding hot water usage such as running multiple showers or a bath simultaneously.
The Rheem 16L gas califont unit is an excellent choice for a holiday home because it is the perfect option for an as-needed basis. This means that it will not use any gas while you are away, saving you money on energy costs. When you return to your holiday home and need hot water, the unit will be ready to use, and you will not have to wait for the water to heat up.
This can be especially convenient if you have a small holiday home with a single bathroom and limited hot water needs. Overall, the Rheem 16L gas califont unit is a practical and cost-effective choice for a holiday home.

For two-bathroom homes:


The Thermann 26L gas califont unit is a larger and more powerful unit than the Rheem 16L, making it capable of supporting the hot water needs of a household with up to two bathrooms. Its 26-liter capacity allows it to manage a higher demand for hot water, making it an excellent choice for families or households with multiple people who need to use hot water simultaneously, such as for showers or baths.
This unit is designed to take the load of a heavier-use household and can deliver hot water quickly and efficiently. If you have a larger home with more than one bathroom, the Thermann 26L gas califont unit may be a suitable option for meeting your hot water needs.

For three-bathroom homes:

The Rinnai HD250 gas califont unit is the largest residential unit available on the market, making it capable of supporting the hot water needs of a household with up to three bathrooms. Its impressive 37L/minute capacity allows it to manage the extremely high demand for hot water, making it a desirable choice for large families or households with multiple people who need to use hot water simultaneously for showers, baths, and other activities.
This unit is designed to take the load of a very high-demand household and can deliver hot water quickly and efficiently, even under heavy usage. If you have a large home with multiple bathrooms and a high demand for hot water, the Rinnai HD250 gas califont unit may be the best choice for meeting your needs.

Costs to install and operate

When it comes to installing and operating a gas califont unit, the size and capacity of the unit will play a significant role in determining the costs involved. In general, the smaller the unit, the less it will cost to install califont and operate. On the other hand, the larger the unit, the more it will cost to install and operate. This is mainly because the larger units have more components internally involved hence the initial price to purchase and the larger units will consume more and will therefore need larger gas pipes to be installed to suffice this.
For example, the Rheem 16L gas califont unit, with its smaller capacity, will be the most affordable option to install and operate among the three units mentioned. On the other hand, the Rinnai HD250 gas califont unit, with its larger capacity and higher demand for gas, will be the most expensive option to install and operate. Therefore, it is important to choose the right unit for your situation, considering your hot water needs and budget.
To conclude, whether you’re looking to upgrade from low pressure or you’re looking at switching out your electric hot water cylinder because it’s not outputting enough hot water, give Hot Water Cylinders NZ a call and discover how you can reap the hot water benefits!
