Gas hot water systems Sunshine Coast

$0 call-out · Fixed price · 24/7 hot water

Celsius Hot Water installs and repairs gas storage hot water systems on natural gas and LPG across the Sunshine Coast. Gas hot water work must be done by a licensed gasfitter, and every installation is tested and certified.

Natural gas or LPG

Mains natural gas only reaches some parts of the coast. Many homes, especially in the hinterland and on acreage, run gas hot water on LPG cylinders. Some systems can be converted between natural gas and LPG with a manufacturer kit and some can't, so we check the model before quoting.

Common gas hot water faults

Pilot lights that won't stay lit, a failed thermocouple, a faulty gas control valve, a blocked flue and a leaking tank are the faults we see most. Outdoor gas units near the beach also suffer from corrosion around the burner and flue.

If you smell gas

Turn the gas off at the meter or cylinder, don't use switches or naked flames, open doors and windows, and call us or your gas supplier's emergency line from outside the house.

Gas hot water replacement

We replace gas storage and continuous flow systems like for like, or move you to a different type. Changing from gas to a heat pump or electric system is also an option. See gas conversions.

Gas hot water repairs

Pilot, thermocouple, gas valve, ignition and flue faults are repaired by a licensed gasfitter, and the system is tested and certified before we leave.

Common questions

Why won't the pilot light on my gas hot water stay lit?

The most common cause is a worn thermocouple, which is a fairly cheap part. Other causes include a faulty gas valve, a dirty pilot assembly or strong wind blowing the flame out on an outdoor unit.

Can a gas hot water system be converted to LPG?

Some models can be converted with a kit from the manufacturer, and others can't. We check your model and give you the options before any work starts.

How long do gas storage systems last?

Gas storage tanks typically last 8 to 12 years, similar to electric tanks. Continuous flow gas units usually last longer because they don't store water.
