Gas Hot Water System

Why choose gas hot water?

Natural gas is one of the cheapest, most efficient ways of generating heat energy. As such, gas hot water systems are generally some of the best, most cost-effective and reliable hot water heaters available. If you’re already connected to the Natural gas network, switching over to a new system might be a very good decision. Especially if you currently own an electric hot water heater, as they are the most expensive hot water systems to run.

If you already have a gas hot water heater that’s malfunctioning, our expert plumbers will rectify your issue with minimal downtime. At Metropolitan Plumbing, we can repair, replace or supply and newly install your heater.

My gas hot water heater can’t be repaired, can you replace it?

In the first instance, our plumber will always try to repair your hot water heater, if viable. But unfortunately, not all hot water systems will be able to be repaired. It may be too old, too damaged, your storage tank may be corroded, or simply not worth repairing. If you’ve had a Metropolitan plumber around to your property, and he’s concluded that a replacement will be a better option, he can still do this job on that visit.

Our plumber will be able to walk you through your options, help you choose the best replacement gas hot water heater for you, then organise a purchase, retrieve it and install it straight away. This also applies if you simply want a new gas hot water system. 

When you’re replacing a gas hot water, it’s now not possible to do so with a model that has an energy star rating of 4 or below. This is because these heaters are considered to be too inefficient and are slowly being phased out. In order to comply with these regulations, you will need to choose a gas water heater that has an energy star rating of 5 or higher. Your Metropolitan plumber will be able to guide you through this process when you’re deciding on your replacement. He will make sure you not only comply with all laws but also that you get the very best appliance for your hot water heating requirements.

Gas hot water heaters are available in two types of systems – storage and continuous flow (also known as instantaneous systems).

Gas Storage Hot Water System

A storage heater can be powered by either natural gas or LPG, which supplies power to a continually burning pilot flame. The pilot flame ignites a gas burner submerged inside the heaters storage cylinder, which heats the water stored inside the cylinder ready for when you require it. The temperature of this water is monitored by a thermostat and the burner automatically turns off once optimum water temperature is reached.

When you use hot water, the storage cylinder automatically refills with water to its capacity and heats the new water. Gas storage heaters are commonly made with a steel storage cylinder that is coated with vitreous enamel which helps the cylinder to resist corrosion. More expensive models feature stainless steel storage cylinders, which can prove to be more durable than the regular steel units.

Most gas storage heaters also feature an added sacrificial anode inside their storage cylinders. Which is a chemical that is designed to break down over the life of the unit and be released into the system, this helps lengthen the life of the unit itself.
