Hot water systems in Hobart
Across Hobart 7000, more homeowners and businesses are rethinking how they heat their water. With power prices biting and an average household size of around 2.3 people, an efficient hot water system is now a smart upgrade rather than a luxury. Many of Hobart’s 6,000‑plus dwellings are older separate houses, with a big mix of rented apartments, so there’s plenty of ageing gas and electric units ready to be replaced with a modern heat pump hot water system, solar hot water system or efficient electric hot water system.
Hobart’s cool climate still offers solid solar potential, with average annual solar exposure of about 13.2 MJ/m² a day – roughly 3.7 kWh/m². That’s enough sunshine to support a well‑designed solar hot water heating system or to help a heat pump hot water system run efficiently, especially when paired with rooftop solar. For households juggling median mortgages of around $1,852 a month or rent of $400 a week, shifting from old gas or resistive electric to an energy efficient hot water system can free up real money each year. The annual hot water energy savings add up quickly when you consider hot water can be one of the biggest loads in a typical Hobart home.
In the 7000 postcode, demand for efficient hot water has been steadily building. Average household size and the strong proportion of families mean consistent daily hot water demand, making efficiency even more important. Many homes are moving away from gas hot water towards all‑electric setups, comparing electric hot water vs gas hot water and weighing up heat pump vs solar hot water to find the most efficient hot water system for their needs. Brands like Rheem, Rinnai, Sanden and Thermann are common choices locally, whether you are looking at a Rheem solar hot water system, a Rheem heat pump hot water unit, a Rinnai solar hot water package or a premium Sanden heat pump.
Typical annual bill savings in Hobart look like this: • Old electric to heat pump hot water system: $400–$800 per year • Gas to heat pump hot water system: $300–$600 per year • Gas to solar hot water system: $250–$550 per year • Old electric to modern electric hot water installation with rooftop solar: $250–$500 per year
There have already been 178 efficient hot water installations recorded in Hobart 7000, combining heat pump hot water installation and solar hot water installation. Install numbers jumped in 2008 and 2009, with more than 50 systems installed in just those two years, and stayed solid through 2010–2013. That early surge shows strong local interest in electrification, lower running costs and cutting emissions. More recently, homeowners are revisiting options as new models, better controls and sharper hot water rebate TAS programs make upgrades even more attractive.
For many properties, the decision now comes down to heat pump hot water price or cost versus solar hot water price or cost and whether a solar hot water vs electric hot water setup makes more sense. A quality solar hot water tank replacement or solar hot water repair can sometimes extend the life of an existing solar hot water system, while others will be better off with a full hot water installation. Likewise, a straightforward electric hot water installation may suit smaller apartments, especially when paired with solar and smart timers, while larger family homes often lean towards the best heat pump hot water system they can afford.
Generous incentives help. Federal Small‑scale Technology Certificates (STCs) reduce the upfront hot water system price for eligible heat pump and solar hot water systems. On top of that, state programs can offer a heat pump hot water rebate, solar hot water rebate or even an electric hot water system rebate in some schemes, cutting the effective heat pump hot water cost or solar hot water cost by a substantial percentage. When you combine rebates with off‑peak tariffs, solar‑diversion and timers, payback periods can drop to just a few years, with many Hobart homes saving hundreds of dollars a year on bills from an energy efficient hot water system.
