If you've noticed your gas or electricity bill continually rising, you may need to consider replacing your hot water system. A faulty hot water system can cost a considerable amount in unnecessary electricity and gas expenditure, so fix the system and you’ll stop paying unending hot water repair costs.

Some reasons why you may need to call for a hot water repair or replacement is because your current system is:

  • Old or outdated, causing inconsistent heating, issues with water pressure, or even rusty/dirty water.
  • Leaking or seeping out water into the surrounding area.
  • Visibly damaged or rusted in ways that may suggest underlying issues.
  • Making noises, such has hissing, clunking, or banging sounds.
  • No longer meeting the hot water needs of the building/household. Eg. being unable to provide hot water throughout the day.

Types of Hot Water Systems

Storage Hot Water Systems

At O’Shea, you can get a storage water heater to store your water in an insulated tank so it’s hot when you need it.

Storage heaters use either a gas burner located in the storage tank or an electric element. The gas units usually have a pilot flame that burns continuously and lights the main burner when it’s needed. Because storage heaters lose heat through the walls of the tank, they need to burn gas or use electricity regularly to keep water at the desired temperature.

With these units, your tank will be well insulated so you have lower storage losses and you can save on gas or electricity costs.

Continuous Flow Hot Water Units

Continuous flow hot water units use newer technology than the storage hot water system. This is because the water is only heated when necessary. As a result, it reduces waste and gives you more temperature control.

These units are more energy-efficient and have a 6-7 star energy rating. They’re also compact so they can be installed in the small spaces of Melbourne homes. Although they may not be as cheap as the storage unit alternative, they’re more efficient and you’ll have an endless supply of hot water.

Solar Hot Water Systems

Solar Hot Water Systems use solar panels as well as electric or gas-powered boosters, to heat the water. It’s the most energy-efficient of all the systems, but also the most expensive to install. You can couple the boosters, used on overcast days, and the tank in two ways:

  • On the roof along with the solar panels
  • At ground level

Installing the boosters and tank at ground level is the preferred option because it avoids the time and expenses required to reinforce the roof. It also gives you easier access during hot water service repairs.

Heat Pump Water Heating

A Heat Pump Water Heater works almost like an air conditioner. This is because it extracts heat from the air along with a refrigerant to produce hot water. It’s an electrically powered system that’s also environmentally friendly.

Hot Water Maintenance

Water heating systems need to be maintained to avoid costly repairs, just like any other system or appliance in a Melbourne home. Without regular hot water maintenance, the integrity of the entire system is in jeopardy and you’ll likely require expensive hot water repairs. A lack of maintenance can result in hot water tank leaks or hot water unit failure.

In addition to timely hot water repairs, it’s important to follow a regular hot water maintenance schedule. For hot water units in Melbourne, it’s recommended to schedule and perform hot water system maintenance every five years. This will maintain the maximum efficiency and safety of the entire system.

Talk to our hot water plumbers in Melbourne about scheduled hot water repairs and maintenance. We can even perform hot water maintenance of your entire system during a repair visit.
