When you upgrade from an older gas or resistive electric hot water system to an energy efficient hot water system, you can tap into serious annual hot water energy savings, especially if you already have rooftop solar or are planning to go all‑electric.
In 2323, most homes are owned with a mortgage or outright, which makes long‑term investments like a new hot water installation more attractive. Families and downsizers alike are looking at the best hot water system Australia can offer for reliability, comfort and lower bills.

Installations spiked around 2009–2011, with more than 500 systems put in over those peak years, and there has been steady ongoing solar hot water repair and replacement activity since.

Typical bill savings from an upgrade in Green Hills look like:
• Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water installation with solar: $250–$500 per year
These ranges depend on household size, tariffs and how much hot water you use, but they give a fair guide on hot water system price versus long‑term benefit. Heat pump hot water price can be higher upfront than a basic electric hot water installation, and solar hot water price can be similar to or above that, but running costs are usually dramatically lower. When you factor in a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate where available, the effective hot water system cost can drop by a substantial percentage.
In NSW, homeowners in Green Hills can typically access Small‑scale Technology Certificates (STCs) for qualifying solar hot water and heat pump systems, plus state‑based heat pump hot water rebate programs that target the switch from gas or old electric units.

Combined with smart use of off‑peak tariffs, timers or solar diversion, payback periods can shrink to just a few years, especially for homes already running rooftop solar. For many, an energy efficient hot water system is one of the easiest ways to cut electricity bills and emissions without changing day‑to‑day habits.
