Oakdowns is well placed for efficient hot water. Local solar data from nearby Rokeby shows mean daily solar exposure of about 13.9 MJ/m², which is roughly 3.9 kWh/m² of sunshine a day across the year. That is plenty of energy for a solar hot water heating system or a high quality heat pump to work efficiently, even through a Tassie winter. With a relatively young median age of 32 and many families with kids, hot water demand is steady morning and night, so choosing the most efficient hot water system can make a real dent in household running costs over the long term.
In 7019, most properties are separate houses with three bedrooms, which suits a 250–315 litre storage hot water system for families and a bit smaller for couples. Hot water can account for 20–30% of household energy use, so it is no surprise Oakdowns homeowners are comparing heat pump vs solar hot water, as well as solar hot water vs electric hot water, to find the balance between upfront hot water system price and long term savings. Brands like Rheem, Rinnai, Sanden and Thermann are popular locally, with options ranging from rheem solar hot water and rinnai solar hot water systems through to premium sanden heat pump and rheem heat pump hot water units for those chasing the best heat pump hot water system on the market.
To give you a feel for savings, here are typical annual bill reductions many Oakdowns households can achieve with the right hot water installation:
• Old electric to heat pump hot water system: save roughly $400–$800 per year. • Gas storage to heat pump hot water system: save around $300–$600 per year. • Gas storage to solar hot water system: save about $250–$550 per year. • Old electric to modern electric hot water installation backed by rooftop solar: save roughly $250–$500 per year.
These numbers vary with usage and tariffs, but they show why efficient hot water is attracting attention from both owner occupiers and the 1,100+ mortgaged households in the area who are keen to keep bills down.
Efficient hot water is not new to Oakdowns. Hot water data shows 53 efficient hot water systems – mainly heat pump hot water installation and solar hot water installation jobs – have been completed in the 7019 postcode. Installations really took off around 2010 and 2011, with a clear spike in those years as rebates and rising energy prices pushed people towards energy efficient hot water system options. While the recorded numbers have levelled off more recently, interest in electrification, getting off gas, and choosing the best hot water system Australia can offer for reliability and comfort is growing again as more people add rooftop solar.
Hot Water Rebates, Tariffs & Savings
For Oakdowns households still on electric hot water vs gas hot water, there has never been a better time to consider a switch. Federal incentives through Small-scale Technology Certificates (STCs) can reduce the solar hot water price or heat pump hot water price by hundreds of dollars at the point of sale.
