Gas Hot Water System Installation

Because of convenience and dependability, many Australian homeowners invest in a gas hot water service installation. Well, that is not surprising since gas hot water systems bring a multitude of benefits. For one, it is unaffected by a power outage.


Before deciding if a Gas Water Heater is for you, here’s everything you need to know about installing a gas hot water system:

What are the different types of Gas Hot Water systems?

As the name implies, this type of hot water service uses natural gas or LPG to power the burner that heats the water you want to use. You either store the heated water (in an insulated storage tank) or heat it immediately (using an instantaneous flow system).

Read on to learn more about the distinction between the two.

Gas Storage Hot Water System

Most gas hot water systems have a gas burner underneath the storage tank to heat the water. Heat is transferred from the gas burner to the bottom of the cylinder, warming the cold water sent to descend in the tank’s bottom. And as the heating cycle progresses, it provides a continuous flow of hot water when required.

In addition, most units have an adjustable thermostat that allows you to control the water temperature. This means you can adjust the water to avoid causing unnecessary damage to the tank and your safety.

Instantaneous Hot Water System

An instantaneous hot water system is the way to go if you want a never-ending hot water supply. Unlike a storage system, it does not store hot water and only heats the amount of water needed for that day. And since a lesser heating process is required, the lower the energy bill.

In other words, it is a tankless water heater with an infinite hot water supply. And it achieves this by travelling water through a heat exchanger inside the unit, which is heated by the gas burner. Depending on the model, it typically delivers hot water at flow rates per minute ranging from 10 to 30 litres.

What to Consider in Gas Hot Water Service Installation?

Whether you want a storage gas or a continuous flow of hot water, there are unique factors to consider in the installation process. And some of them are the following:

  1. Gas Heater Water Type

    Depending on your home’s situation, it is vital to align your gas hot water system to the amenities available in your house. Aside from that, select a water heating system that provides an adequate amount of hot water for your home while allowing you to save money on your energy bills.

    For example, don’t choose a gas storage system when it is obvious that you need an instantaneous water system. To avoid making the wrong decision, you can seek professional assistance from Gasman.

  2. Space and Location

    Manufacturers typically require a certain amount of area for the gas hot water system, which allows ample space for the installation and service. Water heaters should be surrounded by a certain amount of clearance (air space) for proper function and safety.

    In terms of location, it is best to locate the hot water system closest to the hot taps. However, you can also place it near the bathroom, laundry, and kitchen. When it is close to these locations, it helps to reduce heat loss through the pipes.

    A qualified plumber will advise you of the best location for your hot water heater. They will take into consideration your house design, number and location of rooms which require hot water, available adequate space and existing pipes if any.

  3. Tank Size

    The larger your family, the more water you will use.

    To be accurate about tank dimensions, have experts assess your needs and wait for their precise assessment of what tank you should have. Nonetheless, as with any other water heater, they adhere to the local plumbing code.

What to Follow When Installing a Hot Water System?

Individuals frequently overlook specific details when performing an installation. Due to this, experts of Gasman compiled the top storage or instantaneous gas hot water installation regulations.

  • Solder the fittings away from the tank. Closeness can cause the plastic fittings to melt and severely damage your water heater.
