Hot Water System Repairs or Replacement

If your home is having hot water issues, it could be a fault in your hot water system, in the pipes, or in the cylinder. You can have the system checked by one of our professionals who can advise you on the best course of action. If you are replacing a hot water system, you have a few different options, the two most common being a gas 135 litre storage unit or an instantaneous hot water service.

Hot Water Systems

Gas 135 Litre Storage Unit

A standard 135 litre gas storage unit is the most typical natural gas hot water installed at residential properties. Storage hot water systems use a gas burner underneath the tank to heat the water. They have a burning pilot flame that ignites the main burner as required to heat through the bottom of the cylinder.

Most storage units have an adjustable thermostat to set the water temperature. Storage hot water systems come in a range of tank sizes, but the most common residential size installed is a 135 litre tank.

Hot Water Systems

Instantaneous Hot Water System

Instantaneous gas hot water systems, also known as continuous flow units, do not have storage tanks, they heat water as required. The gas burner starts when a tap is turned on. These types of units can have energy and cost savings as they do not have any heat loss from a storage tank, and only heat the amount of water that is required for use at the time, rather than heat an entire storage tank.
