24/7 Emergency Hot Water Repairs & Replacement

With qualified technicians, accredited by the leading hot water system manufacturers, The Network Plumbing emergency hot water specialists can service, repair and replace your hot water system same day.

Leaking hot water systems can ultimately be isolated by turning off the water meter, however, a more practical solution is to turn the hot water system off. This allows cold water to still be used throughout the property and allows toilets and cold water taps to still function.

When you have an emergency hot water system situation we recommend the following:

  • Locate your hot water system.
  • Determine the energy source. Gas electric, solar or heat pump.
  • Determine the type of system storage or instantaneous.
No matter what time day or night, Network Plumbing are your 24/7 genuine guaranteed emergency hot water system specialists.

Hot water system maintenance

Just like your car, your hot water system also requires regular servicing. To ensure the correct operation and to achieve longevity of the system, it is recommended the system be serviced every 1-2 years, depending on the usage, location and wear and tear of your system.

How do you choose the best hot water system?

The saying ‘stick with what you know’ may be true for some things, but unfortunately, hot water systems do not fall under this category. If your hot water system has decided to cark it or you are pre-empting its demise, you should take a read below and consult with a plumber to determine what system best suits you. More often than not, we can provide hot water systems that save more energy and money than customers were experiencing with their old systems.

The first decision is deciding which heating method is best…

Electric
Electric systems usually have lower upfront costs but greater day-to-day running costs – particularly if it is on a continuous flow. Off-peak electrical systems are cheaper but require a more expensive tank to begin with as you will need one with a greater capacity, also, off-peak tariffs aren’t available to every home. Electric systems can be installed inside or outside and come in instantaneous systems too. Generally, a four-person house will require 125-160 litres for a continuous flow system and 250-315 litres for an off-peak system.

Gas
If a natural gas connection is available for your house, it is cheaper than the electrical system as rates don’t vary and can heat the water as you need it. Liquid petroleum gas (LPG) can be an alternative to natural gas but this type of gas usually sees more expensive everyday costs than natural gas. These systems usually need to be stored outside for venting requirements and have an energy efficient star rating. A four-person household will require a tank between 135-170 litres.

Solar
Solar hot water systems are one of the most expensive to install but in the long run can pay for itself as it has very low running costs, also, government incentives and rebates can offset the more expensive purchase cost. This is a great option if you can install panels in an ideal location. A four-person household will usually need two panels and a tank that holds between 300-360 litres.

Heat Pump
A heat pump hot water system is one of the most efficient systems and works by extracting heat from the air to heat the tank. These units can be integrated with the tank and compressor together or split with the tank and compressor separate. These systems can be quite noisy due to the compressor and also need to be installed in a well-ventilated area. A four-person household will need a tank capacity of 270-315 litres.

After deciding on your heating method, you will need to decide between a storage tank or continuous flow system…

Storage Tank
Most electric, gas solar and heat pump hot water systems use a tank as the storage method. Tanks usually last around 10 years but the ‘sacrificial anodes’ tend to last around 5 years. These anodes attract minerals that would otherwise corrode the tank, meaning that it sacrifices itself for further longevity of the tank.

Continuous Flow
Continuous flow or instantaneous systems only heat the water as you need it, it may take a few seconds or more to heat the water completely – particularly if there is some distance from the hot water system and the tap. Most continuous flow systems are available in gas or electric models and because you don’t lose heat like storage tanks do, these systems are cheaper to run.

For all your hot water system needs

We all tend to take our hot water systems for granted until the very day they decide to stop working. From showering to cooking and washing up, we often forget just how big of a role our hot water system plays in our everyday lives. At Network Plumbing we understand the need to be able to contact a plumber at any hour for emergency repairs, maintenance or installation. While hot water systems may seem a little complicated and easier left in the back of our minds, we recommend that all of our customers take the time to regularly maintain and check on your hot water system. Hot water tank systems are the ones that usually require the most attention as they build up pressure each day. The sacrificial anodes and temperature and pressure relief valve are the two main things that you should keep in mind. A sacrificial anode is a rod that is coated in zinc and hangs down inside your water tank. The sacrificial anode is specifically designed to attract any minerals in the water that would otherwise rusted and corroded the interior of your tank. They are instead attracted to the anode which ‘sacrifices’ itself for the longevity of your hot water tank. These anodes should be replaced around every five years by a professional plumber, if you are unsure when they were last replaced you should get in touch with a plumber as soon as possible. Temperature and pressure relieve valves are fitted to hot water tanks as an extra method of precaution. These valves work by reducing the temperature and pressure in your hot water tank if it reaches a certain point – this is a necessary precaution as otherwise your hot water tank is at risk of exploding. Every hot water tank brand as its own life expectancy for temperature and pressure relief valves, however, as a good rule of thumb, you should replace this valve at least once every two years. If your valve is nearing the end of its lifetime, it is best to get in touch with a local plumber sooner rather than later. For all other general servicing, there are different guidelines for each different heating method. Generally, your system should be given the once over by a professional plumber at least every five years at the bare minimum. If your hot water system is experiencing; irregular changes in temperature, changes in water pressure, leaks, sediment in water or odd sounds – it is best to contact a plumber immediately.

Need a new hot water system?

It can sometimes be hard to tell if your hot water system is just in need of some maintenance and repair or if you are better off with a whole new system. At Network Plumbing we want the most cost-effective solution for you and we are happy to come and take a look at your system and let you know what your options are and what we recommend. Here are a few pointers to take into consideration…

How old is your hot water system?
Most hot water systems are expected to last for ten to twelve years, each brand and system varies slightly so if you have the original manufacturer’s booklet you may find a more precise timeframe. While it is not uncommon for hot water systems to outlive their life expectancy, don’t be surprised if one day your system just decides that it has had enough. If you don’t have any information about your system, a Network plumber can come and take a look to determine when it was installed and if it needs repairing or replacing.

Is your hot water hot enough?
If your shower is turning cold before you have finished, or you have turned the tap to the hottest possible and it’s still not hot enough, there may be a few factors at play. A faulty thermostat or broken heating element is most likely the cause rather than an entirely broken system. If the thermostat or element are the problem, this is a quick process that can be carried out by a qualified plumber.

Are there any noises coming from the tank?
Hissing and sizzling sounds are not part of a hot water systems every day running and is generally an indicator that it is on its way out. Sometimes these sounds may be due to a faulty relief valve and all that needs to be done is a small replacement, a professional plumber can supply and install the correct valve with the right pressure rating in no time at all. If you hear anything out of the ordinary, be sure to get in touch with a plumber right away.

Is your tank corroded or rusted?
Depending on your location, corrosion around your hot water system and its fittings may be an indicator that you have a leak. If you live near the beach, it may just be a result of the salty air, but it also could be an indicator of a greater problem. A plumber will be able to identify if this is the case and if the fittings just need to be tightened or if they need to be replaced entirely.

Hot water systems Sydney

There are many different hot water system brands, sizes and types that are available, and customers often find the whole process a little overwhelming. Your hot water system can often account for more than a fifth of your annual energy use, so it is very important that you choose the right system to help both your bank account and the environment. At Network Plumbing, we are more than happy to lend a hand to help you determine what one best suit your needs.

Mains Pressure Storage Hot Water
This kind of hot water system is available in electric and natural gas models, it stores hot water in a cylinder and is ready immediately. There is a thermostat in the cylinder that keeps the water heated to a set temperature, when hot water is used it is replaced with cold water in the tank and reheated. Any drop in temperature will set off the element or burner which triggers the reheating.

Continuous Flow
Continuous flow hot water systems are available in natural gas and solar. Natural gas continuous flow heats the water as you use it which means you have an endless supply of hot water and can control the temperature that it will be delivered to you at. Solar continuous flow uses the sun to heat your water. In summer, your solar system should supply most, if not all of your hot water needs, however on cold or overcast days a booster may be required to give you the hot water supply that you need. A gas-boosted solar system can reduce greenhouse emissions by 75% when compared with electric systems hot water systems.

Electric Off-Peak
Electric off-peak systems are connected to an off-peak tariff which means you will be charged lesser rates for heating outside of peak time. Your hot water is heated for eight hours at night and five hours during the day so that you will always have hot water. A two-bedroom household should have a minimum storage of 250 litres, a three-bedroom should have a minimum 315 litres and a four bedroom should have a minimum 400 litres.

Heat Pump System
Heat pump hot water systems use energy from the atmosphere no matter the day, time or weather, like a fridge it will transfer heat that is extracted by energy collectors. A compressor is the only electrical energy that is used, meaning that it uses a third of the power used by normal hot water systems. No booster is needed, and this system leads the way for reducing greenhouse emissions.
