Hot water systems in Penna
Across Penna and the 7171 area, more locals are swapping old gas and ageing electric units for an energy efficient hot water system that actually suits Tasmanian conditions. With an average household size of around 2.4 people and most homes being separate houses, many families and downsizers are looking for reliable hot water that keeps bills under control without sacrificing comfort.
Penna’s solar exposure is better than many people realise. The nearby Orielton station records mean daily solar exposure of about 13.9 MJ/m², which works out to roughly 3.9 kWh/m² per day over the year. That is plenty of free energy to support a solar hot water system or boost the efficiency of a heat pump hot water system, especially if you already have rooftop solar. With median household income around $1,522 a week and more than 1,100 families in the postcode, shifting from gas or older resistive units to modern heat pump hot water or solar hot water is a logical way to lock in long‑term savings.
In Penna, most dwellings are three‑bedroom separate houses, so hot water demand is steady rather than extreme. For many homes, the most efficient hot water system will be either a quality heat pump hot water system or a well‑designed solar hot water heating system with an electric booster. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, with options ranging from compact electric hot water installation for smaller households through to high‑performance Sanden heat pump units or roof‑mounted Rheem solar hot water and Rinnai solar hot water systems. If you are comparing heat pump vs solar hot water, your roof space, shading, and when you use hot water will all influence which comes out on top.
Average annual bill savings from an efficient upgrade in Penna can look like:
• Old electric hot water system → heat pump hot water installation: save roughly $350–$700 per year. • Gas storage → heat pump hot water system: save around $250–$600 per year. • Gas storage → solar hot water installation: save around $300–$650 per year. • Old electric → modern electric hot water installation with rooftop solar: save roughly $200–$500 per year.

Hot Water Rebates, Tariffs & Savings
For Penna households, the economics are helped along by hot water rebate TAS programs and national incentives. Eligible heat pump hot water installation and solar hot water installation can create Small‑scale Technology Certificates (STCs), which act like an upfront discount. On top of that, Tasmanian and Federal schemes can provide a solar hot water rebate, heat pump hot water rebate or even an electric hot water system rebate in some cases. Together, these can cut the effective hot water system price or solar hot water price / cost by a significant percentage, trimming thousands off larger systems and shortening payback periods to just a few years. When you factor in the heat pump hot water price / cost over its lifetime, plus the ability to run it on off‑peak tariffs or daytime solar, it often stacks up as the best heat pump hot water system option for many Penna homes.
Using timers or smart controls to run a heat pump during solar hours, or to prioritise a solar hot water vs electric hot water boost, can push savings even further. For many locals, the choice has shifted from electric hot water vs gas hot water to which style of efficient system best suits their roof, budget, and plans for an all‑electric home.
