What To Do If You Have No Hot Water

Can you remedy the problem yourself? Suggestions will differ depending on whether your water heater is powered by gas or electric. For an electric water heater, you can try switching it off for a few minutes and then back on again. Wait half an hour, and you may find this resolves the problem. If this doesn’t help, there may be a more complex problem which needs professional attention. Call our local licensed experts who will be able to deal with the issue quickly and efficiently.

For a gas water heater, you can try turning the pilot light off and then on again. Locate the regulator and switch it off. Doing this will turn the pilot light off. There should be instructions on the unit for reigniting the pilot light. Follow these instructions, and this may resolve the problem. If this doesn’t restart the system, you may need help from one of our skilled plumbers. You may notice a smell similar to rotten eggs, which can indicate there is a gas leak. Turn the gas valve off and call our team of experts urgently. We run a 24-hour service so we can assist you, whatever the problem and whatever the time.

Hot Water Maintenance Is Important

Whether your hot water system uses gas or electric, it will need regular servicing to ensure it is both safe and effective. Boilers have specific safety features installed to gauge the pressure and temperature of the water. If the water temperature becomes too high, the pressure release valve (TPR) will expel water to resolve the issue. If the pressure relief valve is broken or ineffective, the boiler may explode. 


Calcium and rust deposits can occur and result in a variety of things including the inability of the system to heat the water efficiently, leaks and even contamination of the water supply. It’s a false economy not to have these annual checks carried out. The cost of safety and maintenance checks far outweighs the cost of replacing a broken boiler or damage to the health of you and your family. Can you afford not to have your system checked and maintained annually? Contact our team of licensed experts in the North Shore today. We can arrange a call out for general repairs and regular maintenance. A safe and effective hot water system is a reliable hot water system.

Hot Water FAQs

What’s the best temperature setting for my hot water system heater?

If the temperature on your water heater is set too high, it can result in scalding injuries.  On the other hand, if the temperature is too low, it can allow bacteria such as Legionella to flourish. Legionella contamination can result in severe damage to the health of you and your family and can even be fatal. To ensure bacteria can’t thrive, a temperature of 60C is optimal for stored water. 

Tap water at a temperature of 50C may be better for families with children or older adults. Our licensed experts can ensure you have a tempering valve installed on your system for this purpose. If you don’t, or if the current valve is ineffective, our licensed experts can remedy the problem for you.

How often should I replace my hot water system?

The answer depends on several factors which you can bear in mind when considering a replacement:


  • Is the water temperature inconsistent? 
  • Is the heater leaking? Corrosion can cause leaks to the system, and while it’s possible to repair a small crack, this is just a stop-gap.
  • Does it cost you more money to heat your water? An inefficient or older boiler will cost you more in the long run.


We have 15 years of experience in dealing with many different types of hot water systems. If you are considering a replacement system, speak to our licensed experts, who will be able to recommend a system which is just right for your home in the North Shore. 

Why is my water heater making rumbling noises?

Over time a residue may form which can seriously affect the efficiency of your water heater. You can try to resolve the problem by draining off some of the water. Attach a garden hose to the valve located on the bottom of your water heater. Care is needed as the water may be extremely hot and result in a scalding injury.  Hot water can also damage the drainage receptacle and your garden.

Stay safe and prevent damage to your home. Call our licensed experts to sort the problem out for you. We are on call, 24 hours a day, so we’re always available to help.

Deciding on which heater to buy very much depends on what you need from your hot water system. Is price the overriding factor? Then a standard insulated storage tank with a temperature and pressure control valve may be the best option. These systems heat and store hot water and keep it at a given temperature until needed. They are reasonably priced and simple to use.

If you are more concerned with energy consumption, then maybe a tankless heater would be a better option. Tankless heaters use super-heated coils to heat the water as it is needed. These are available in gas or electric, and both are energy efficient.

Some people try to fix or install their hot water systems with the idea that it will be cheaper than calling a professional. However, it could potentially cost more in the long run. Consider some of the issues involved before commencing any such work on your hot water system. 


  • Boilers are potentially explosive if fitted by an unqualified person without the proper knowledge or tools. 
  • If the heater is gas-powered, there is an additional risk of gas leakage, which could be life-threatening. 
  • Incorrect installation could reduce the lifetime of your boiler, resulting in early replacement.
  • The guarantee is unlikely to remain valid if an unqualified person fits the appliance.
