Upgrade a customer from a gas storage water heater to a compact instant gas hot water system.
We recently assisted customers in Lakemba who were renovating their home and wanted to make better use of the narrow area down the side of their house. The existing gas storage water heater had served its purpose, but it was bulky, inefficient, and occupying valuable space they wanted to reclaim as part of their renovation.
As part of their renovation, they asked us for advice on a more modern, space-saving and energy-efficient hot water solution. After inspecting the property, we recommended replacing the old water heater with a new Rheem 28 litre Instant Gas Hot Water System. The compact, wall-mounted unit provides continuous hot water while freeing up the ground area for other uses.

Why upgrade to instant gas hot water?
Instant (often called instant or continuous flow) gas hot water systems are ideal for homeowners who want efficiency, performance and convenience. Instead of keeping a large tank of water heated all day, these systems only heat water as it’s needed, cutting energy waste and running costs.
- Lower energy use because water is heated on demand
- Endless hot water supply for growing families
- Compact, wall-mounted design that saves outdoor space
- Reduced gas consumption and lower emissions for a greener home
- Consistent water temperature for comfort and safety
- Ability to link multiple units for homes with higher hot water demand

Gas water heater installation
We safely removed the old storage tank, taking it away for recycling. We then installed the new instantaneous system on the exterior wall of the home. The compact design allowed the homeowners to utilise the side of their house for storage and landscaping while still enjoying reliable, energy-efficient hot water.
The transformation was immediate: lower running costs, unlimited hot water, and a neater outdoor space ready for their renovation plans.
