That steady sun supports both a solar hot water system and a heat pump hot water system, especially when paired with rooftop solar. Many locals are now comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to find the best balance of upfront hot water system cost and long‑term savings.
In a postcode where a large share of homes are owned outright or with a mortgage, upgrading from older gas or resistive electric hot water to an energy efficient hot water system is a logical next step. Hot water can be one of the biggest energy users in the home, so shifting to a quality heat pump hot water system or solar hot water heating system can deliver strong Annual Hot Water Energy Savings for Mardan households.
For a typical 3–4 person home, a 250–315 litre heat pump hot water installation or solar hot water installation will usually cover daily demand. Many Mardan homes already have rooftop solar, making a modern electric hot water system or a rheem heat pump hot water unit on a timer a smart way to soak up excess solar. Brands like Rheem, Rinnai and Sanden heat pump systems, as well as Chromagen solar hot water, are common choices for those chasing the best hot water system Australia can offer in regional conditions.
When you look at bills, the numbers add up quickly. Depending on your setup and usage, typical average annual bill savings in Mardan might look like:
• Old electric to heat pump hot water system: save around $450–$900 per year. • Gas to heat pump hot water: save roughly $350–$750 per year. • Gas to solar hot water system: save about $300–$700 per year. • Old electric to modern electric hot water installation with solar: save around $300–$650 per year.

Hot Water Rebates, Tariffs & Savings
For hot water VIC homeowners in Mardan, generous incentives are helping to bring the heat pump hot water price and solar hot water price down to earth. The Australian Government’s Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on eligible systems, and Victorian hot water rebate programs can further reduce the heat pump hot water cost or solar hot water tank replacement cost. There are also schemes that support an electric hot water system rebate when you move away from gas.
When you stack these incentives together, it is common for rebates to trim the system cost by 30–50%, sometimes more on selected models. Combine that with hundreds of dollars per year in bill savings and the payback period on a quality rheem solar hot water, rinnai solar hot water, sanden heat pump or chromagen solar hot water unit can be cut dramatically. Smart use of timers, off‑peak tariffs and solar‑diversion controllers can push you towards the most efficient hot water system performance, especially if you are aiming for an all‑electric home.
If your current unit is older, noisy, leaking or still running on gas, now is a good time to check whether your Mardan property is ready for a hot water upgrade.
