Our Plumber was Matthew a very pleasant young man. He was on time for the booking of the appointment. Very confident with his trade, very polite and efficient. He was careful not to damage any fixtures around the installation area. He cleaned up all and any mess created with the emptying of the old tank. He seemed to take pride in his work and was very skilful. I feel that he went above and beyond from what I had experienced in the past from other plumbers. A credit to the Atomic Hot Water Repairs company and a fine representative. Don't let him go. In any other future plumbing needs we may have, I would not hessite to call this company again.

The team at atomic got me out of a pickle when my old electric hot water system burst. They had me back up and running with a brand new instant gas hw system the very same day and also took the old one away. One stop shop that could do all the gas and electrical work. They were all covid safe and wore all the correct gear. Very polite and professional installers who took the time to clean up after themselves and explain the new system and troubleshooting steps should there be an issues. Competitive pricing and I highly recommend.

Steve was very friendly and got my hot water system up and running again with no problems. I particularly appreciated that I received a phone call from him, in advance of the time which I had booked, asking if it was OK to come a little early - very efficient and courteous service.

Whilst you are waiting for professional help, you can turn your water off at the mains connection. The tap should be somewhere near the front of your property. If you are in a unit block or duplex we suggest you check with your fellow residents first.
You can stop power to your unit by switching off the fuse in your power box. Just switch off the fuse relating to your water heater and wait for professional help.
Hot water heaters are often in tight spaces, especially older models. We will do our best to minimise mess and any impact to the surrounds whilst we repair and/or replace your heater. We have seen water heaters in a lot of imaginative places!
We recommend you vacuum the filters at least once a month during winter or when the heater is most in use. You also need to service your heater every 12 months to get the most out of it. When we service your heater, we check the gas and inlet pipelines, ensure the injectors are not blocked or attracting build up. We blast compressed air through your heater to remove any excess dust or debris that will compromise performance. We ensure the filters are comprehensively cleaned and also give it a general wipe down and polish, ready to be at its best in your home!
We will turn around your room heater service in under 48 business hours. If we find anything requiring repair, we will contact you to let you know. This may delay the turnaround time.
How does a water heater work? Well, a water heater is an appliance that uses energy (e.g. gas or electricity) to heat up water and supply it in liquid form when needed. There are two types of heaters: storage tanks and instantaneous (or continuous flow) systems. A storage tank system heats up water in a large insulated tank and supplies it as needed while an instantaneous system provides hot water on demand without the need for a preheated stored volume of hot water. The inner workings of a typical heater include an electric or gas burner, a thermostat to control temperature, heating elements, and insulation to retain heat from the heated water. A variety of safety features such as overheating protection helps prevent accidents due to high temperatures. The average lifespan of a water heater is 8-12 years, depending on the type, proper installation, and regular maintenance.
There are 2 basic types of hot water systems: storage systems and continuous flow (or instantaneous) systems. Both can heat residential homes and commercial establishments using one or more energy sources. Storage systems heat water in a tank and supply it to taps as needed. They are generally cheaper to purchase and install than continuous flow systems, but they also tend to lose heat over time, which can result in higher running costs. Continuous flow systems provide hot water on demand, meaning that you don’t have to wait for the tank to fill up before you get hot water. They use less energy than storage systems but usually cost more initially due to their complexity. Both types of systems require regular maintenance including flushing out the storage tanks or descaling the system if hard water is present. It’s important that any repairs or servicing be carried out by an experienced professional who knows hot water systems. No matter what type of hot water system you have, it’s important to ensure that it is installed and maintained correctly for safety and efficiency. With the right care, your hot water system can provide reliable service for many years to come.
Commercial hot water systems are systems that provide hot water for use in businesses. They can be either electric or gas-fired, and typically have a large storage tank so that they can provide hot water on demand. A quality commercial hot water system can save businesses money on energy costs, as it can be more efficient than traditional heating systems. They are also safer and more reliable, as many have built-in safety features. Most of these systems come with programmable settings that allow users to set the temperature for different times of day or week. This makes them very versatile, as different temperatures may be needed for different purposes. Additionally, some systems come with a control box that allows users to monitor the status of the system remotely from their computer or smartphone. Commercial hot water systems usually require regular maintenance to keep them running efficiently and safely. This often involves flushing out the storage tank and replacing filters periodically. Additionally, it is important to check the pressure relief valve and safety release valve regularly. Lastly, it is important to make sure that (for electric heaters) all electrical components are in good working order. To ensure that your commercial hot water system runs effectively and safely, it’s important to consult with an experienced technician to determine the best solution for your particular needs. A technician can evaluate your current system and advise you on what type of system is best for your business. They can also provide advice about maintenance requirements and other aspects of using a commercial hot water system. With the right knowledge and expertise, you’ll be able to get the most from your commercial hot water system.

Electric heat-pump hot water heaters use less electricity than electric storage water heaters, making them some of the most efficient types on the market. They are also very safe, as they use a liquid coolant similar to that found in refrigerators and freezers. Electric hot water heaters come in both tankless (instantaneous) and storage models, but electric tankless heaters tend to be more energy efficient, as there is no need for a large storage capacity.

Electric hot water systems are highly customizable – their temperature setting can be adjusted according to individual needs. They also have built-in safety features such as overheating protection that minimizes the risk of accidents or damage due to high temperatures. However, they require regular maintenance such as descaling and flushing out sediment from the system. Additionally, if you live in an area with tough winters, it’s important to install an electric hot water system that is capable of withstanding extreme temperatures.

Overall Electric Water Heaters are a well rounded effective means of providing your home with clean warm (or hot!) water. Talk to us today to learn if an Electric Hot Water System is right for you.

Tankless water heaters, also known as “demand” or “instantaneous” water heaters, provide hot water on demand without the need for a storage tank. The main benefit of these systems is that you have an endless supply of hot water as they do not store a limited capacity of hot water.

Tankless units use either electric, natural gas or LPG to heat up your water as soon as it enters your home, while simultaneously using less energy than traditional storage tank models. The main benefit of these systems is that you don’t longer have to wait for hot water, as they provide it instantly. Additionally, tankless systems are highly efficient and can save you money in the long run.

Regular maintenance is key to ensure that your tankless system performs at its best. Parts such as filters and nozzles need to be cleaned regularly to prevent clogging. Also, if you live in an area with hard water, descaling the inside of the heater may be necessary every few years to maintain efficiency and avoid corrosion.

Gas hot water systems are the most popular type of system in Australia and tend to be more cost-effective than electric systems. They use natural gas or LPG, which is generally a cheaper energy source than electricity, meaning that running costs can be much lower. Additionally, gas hot water systems are relatively easy to install and operate and come in both tankless and storage models. However, there are some drawbacks to using gas hot water systems. For one thing, they require regular maintenance such as descaling or flushing out sediment from the system. Additionally, if you live in an area with tough winters, it’s important to install a model that is capable of withstanding extreme temperatures. Gas heaters also release waste into the environment – something to consider if you’re looking for an environmentally friendly option.
