Hot Water Systems Maintenance​

Depending on what type of system you have, the maintenance ranges from system to system. Regardless of what system you have preventative maintenance is crucial. It is not hard to forget how much we need our hot water systems. Hot showers during winter, washing a greasy pan, or using warm water to wash your clothes; we do not often realise how important and convenient having hot water is until there is no longer hot water coming out the tap. 

Like all electrical and mechanical appliances, hot water systems require regular maintenance to function efficiently. When speaking of hot water systems, hot water tanks require extra attention as it stores hot water and builds up pressure. Whereas instant hot water tanks do not store water and heats water when it is demanded.

Specific to hot water tanks, it is important to consider:

What is a sacrificial anode?

Sacrificial anode refers to an aluminium/magnesium wrapped steel core wire which will corrode in place of the tank – hence ‘sacrificial’. However, once the rod is entirely corroded, other steels parts of the tank will start to rust. The sacrificial anode is replaced every 5 years to prevent major tank faults.

The sacrificial anode is the most important component of hot water tank maintenance. It is crucial to replace this rod regularly to prevent major repairs and even total tank failure. By paying attention to this component and scheduling routine replacements, the hot water tank’s service life can easily be extended by at least another 5 to 10 years.  

Sacrificial anode replacement is not a task that you should be conducting yourself. Hot water tanks hold scalding hot water and steam which is directly attached to a gas or electrical source. Hot water + steam + gas / electricity = an extremely dangerous scenario.

The replacement can be done by an experienced and qualified plumber who will service and inspect the entire system and replace the sacrificial anode. Servicing your hot water tank regularly carries minor cost compared to the major expenses you would otherwise have to pay to replace or repair major faults.

Service idea!?

“Similar to routine customers, have a routine sacrificial anode replacement every time someone installs their hot water tank with us. Takes one thing away from what they need to worry about.”

Matt and Aaron from Alliance were terrific. They were courteous and efficient and nothing was a bother. As an added bonus, they left my house cleaner than they found it!Alliance are so reliable that we just used them again. Apart from aircon maintenance, they replaced an old and broken video intercom system and diagnosed why our outdoor lights aren't working. An outstanding job - and service! - from Chris, JJ and Vashil.

The team from Alliance installed my split system air conditioner today - and I was so impressed! The guys arrived on time, they came with everything that was needed and clearly knew what they were doing. Andre, Adam and Dragan had clearly worked together many times and their teamwork was evident. Chris looked after the electrical side of the installation and also did a top job. Each of the guys were super polite and worked really hard. They took away the old, broken system and cleaned up at the end of the job. Everything that had been moved to do the installation was put back to the way it was found. These guys are top notch. Would highly recommend this company. From the first site visit to the close of the installation today, every communication was terrific and well organised.

Gabriel was very courteous, polite and professional.He was also very thorough, making sure that he inspected every component (even though it was a struggle in the confined ceiling space). The "booties" for work inside the house was a very nice touch.

Steven arrived well within the promised time, notified us on arrival and proceeded to inspect and advisee on condition of the existing 7 year old unit. He gave professional advice and explained in detail the various options available in a clear and concise manner. He provided detailed written quotations for each option. Very professional approach.

Yesterday we had a replacement Dakin split system installed in the place of our previous Daikin split system which needed replacement after 17 years of use.Whilst investigating to find a suitable supplier I came across Alliance Climate Control.Within a short time of calling them, a qualified expert was at my front door and I received a written quote.I compared this quote and how the installation would take place and I quickly came to the conclusion that Alliance was in a league of their own.The service received both before installation and during installation cannot be faulted in any way. Whatever they promised would happen, happened exactly as they said it would. Apart from having the best make of split system aircondioner supplied, their staff with whom I dealt with cannot be faulted. i Specifically commend BJ, Adam, Benjo, JJ, Vash, Chris D and Jac.They were great.i commend Alliance unreseredly.Ted S.

We had lots of problems with the installation. The agreed upgraded unit did not fit into the existing hole. A new unit arrived and it was the same unit we were replacing that Alex (Alliance rep) told us was not the right unit for our home. Eventually it was decided that the upgraded unit would fit under the house and an under the house unit was then used. After lots of delays Andres and his team were able to rectify all the problems in a very professional manner.

What are temperature and pressure valves?

These valves are often referred to as TPR or T&P valves. These valves work to vent hot water from the tank if the pressure or the temperature of the hot water becomes excessive. This is a crucial component that will prevent your hot water tank from exploding or splitting. A TPR valve that is not functionally correctly can cause life-threatening consequences.

Generally, TPR valves should be inspected and replaced every 2 years. But this depends on the condition and capacity of your water tank. It is best to speak to a qualified plumber about your hot water tank to receive tailored advice for your home.

What about tankless hot water systems?

Otherwise known as instant hot water systems also need preventative maintenance to make sure that is functioning efficiently and correctly. The main consideration with tankless water heater is ‘hard water’.

Hard water occurs when the water is loaded up with minerals like magnesium and calcium. Over time, minerals can clog up the pipes where water flows and affect the water flow speed. Which means the system will need to work harder than it should to provide hot water.

Routine maintenance is important to extend the life of your system. A qualified plumber will be able to clean out the heat exchanger to allow the system to work more efficiently. When hard water is left alone, the mineral build-up in the system can cause the entire unit to fail which will require a replacement.

Hot Water Systems Helpful Tips

Regardless of which hot water system you invested in, tankless or storage – it is a big investment that you’d want to take good care of so it lasts 8-12 years in your home. 

Plus, no one wants to run out of hot water in the middle of a shower especially during winter. So, here are some helpful tips to make sure that doesn’t happen.

Regular check-ups

Surely, you’ve heard the saying “If it ain’t broke, don’t fix it”. This basically refers to not bothering something that is working on something that is working ‘just fine’. However, this philosophy doesn’t apply to mechanical and electrical appliances that can actually breakdown – like your hot water systems.

 

Hot water systems when left alone for too long with minor issues may need major repairs or even a replacement in the long run. Generally, it is wise to check on your electrical appliances on a monthly basis. It would only take you 5-10 minutes to inspect each appliance. For your hot water system, check the unit from top to bottom and look for any leakage, cracks, rust or other physical signs of concern.

Pressure Valve

Every 6 months, you need to make sure that your system’s pressure valve is still working well. This is designed to relief any excess pressure within the hot water system. Depending on the type of system you have, each check is slightly different so make sure you locate and understand the tank’s manual before proceeding with this task.

If you are not confident with this task, schedule in a routine maintenance with your plumber and while they are on-site they will be able to demonstrate this procedure to you.

Hot Water Holiday

If you are going to be away for a long period of time (over a week), make sure you turn off your hot water system. This way, you won’t need to come back from your holiday with a surprise from your energy bill! While you are away, the hot water system will continue to heat water although no one is home to enjoy the hot water. So make sure this is part of your checklist before you rush to the airport.

Efficient Showerheads

The traditional showerheads that are installed in most homes uses around 15-25 litres per minute. Whereas a water saving showerhead (WELS rated) uses between 6 to 9 litres per minute without restricting the water flow. This means a water efficient showerhead can save you more than 63 litres of water for a 7-minute shower.

Tank Temperature

Hot water tanks only need a temperature of 60° to maintain healthy hot water to limit the growth of microorganisms in your tank. During your next maintenance, ask your electrician/plumber to check the temperature is nothing higher than 60° and your wallet will thank you for reducing the hot water running costs.
