Deep Bay is well suited to efficient hot water. The nearby Gardners Bay weather station records an average solar exposure of about 13.2 MJ/m² per day – roughly 3.7 kWh/m² – across the year. That steady sunlight helps a solar hot water heating system or heat pump hot water system perform well, especially when paired with rooftop solar. For households on fixed incomes or with a median weekly family income of about $1,271, shifting hot water off expensive grid energy can deliver meaningful annual hot water energy savings.
Across the 7112 postcode there are 1,400‑plus dwellings, mostly separate houses with decent roof space, making solar hot water installation and heat pump hot water installation straightforward in many cases. Hot water energy use can easily account for a quarter of a typical home’s electricity bill, so moving from older resistive electric or gas units to the most efficient hot water system you can afford is a smart move. Brands like Rheem heat pump hot water, Sanden heat pump systems and Rinnai solar hot water are common choices for efficient upgrades, while Chromagen solar hot water and Rheem solar hot water remain popular for coastal homes looking to harness the sun.
Average annual bill savings in Deep Bay will vary by household and tariff, but realistic ranges look like:
• Old electric to quality heat pump: $350–$800 per year • Gas to heat pump: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water with good solar: $200–$450 per year
These savings depend on the hot water system price, your electricity plan and how much daytime solar you can use, but they show why many locals now compare heat pump vs solar hot water and solar hot water vs electric hot water when planning their next hot water installation.
In Deep Bay and the broader 7112 area, at least 80 efficient hot water systems – mainly heat pumps and solar hot water – have already been installed. Installations ramped up around 2009–2011, with 10 systems a year going in at the peak, and another spike in 2014. More recent years show a steady trickle as early adopters replace old systems and new residents choose an energy efficient hot water system from day one. Each new solar hot water installation or heat pump hot water installation reflects the shift towards electrification, lower running costs and quieter, cleaner homes.
Hot Water Rebates, Tariffs & Savings
For homeowners in Deep Bay TAS, generous hot water rebate programs help bring the hot water system cost down. Federal Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump hot water systems, effectively discounting the upfront solar hot water price or heat pump hot water price at the point of sale. On top of that, Tasmanian households may be able to access state‑based heat pump hot water rebate or solar hot water rebate offers from time to time, as well as an electric hot water system rebate in some programs aimed at moving homes off gas.
When you stack rebates with a competitive solar hot water price or heat pump hot water price and off‑peak or solar‑friendly tariffs, the payback period can shrink to just a few years. Many Deep Bay homes can realistically save hundreds of dollars a year. Using timers or smart controls to run a heat pump during the middle of the day, or diverting excess rooftop solar into a solar hot water tank replacement, can turn your system into the most efficient hot water system possible for your site. For many households, electric hot water vs gas hot water is no longer a close contest – efficient electric and solar options win on running costs and emissions.
