Hot water systems in Rokeby

Across Rokeby, more locals are rethinking their old gas and electric units and upgrading to a modern hot water system that is cheaper to run and easier on the environment. With an average household size of about 2.5 people and more than 2,900 occupied dwellings, hot showers, dishwashers and washing machines add up quickly on the power bill. For families on a median household income of around $1,306 a week, shifting to an energy efficient hot water system is a simple way to free up money every year.

Rokeby’s climate actually helps. The local weather station records mean daily solar exposure of about 13.9 MJ/m², which is roughly 3.9 kWh/m² per day over the year – plenty of sunlight to support a solar hot water system or boost the performance of a heat pump hot water system. On a typical separate house roof, that translates into strong output from a solar hot water heating system and reliable operation from quality brands like Rheem, Rinnai, Sanden and Chromagen. When you combine that with the suburb’s high rate of separate houses, it makes sense that many homes are now looking at heat pump vs solar hot water as a genuine choice when the old tank finally gives up.

In Rokeby 7019, most homes are three‑bedroom places, so hot water demand is steady rather than extreme, but it still represents a big chunk of household energy use. Many older properties still rely on gas or a basic electric hot water system, which can be expensive on current tariffs. That is why we are seeing more interest in heat pump hot water installation and solar hot water installation alongside newer, well‑insulated electric hot water installation options that are designed to work with rooftop solar.

Typical annual bill savings for Rokeby homes can look like this:

• Replacing an old electric hot water system with a heat pump hot water system: around $350–$700 per year. • Switching from gas to a heat pump hot water system: roughly $250–$600 per year. • Switching from gas to a solar hot water system: about $300–$650 per year. • Upgrading an old electric unit to a modern electric hot water system run mostly on solar: around $250–$500 per year.

Local installers are regularly fitting systems such as Rheem solar hot water, Rheem heat pump hot water, Rinnai solar hot water and premium units like the Sanden heat pump. These are often shortlisted when people search for the best hot water system Australia wide or the best heat pump hot water system for colder climates like southern Tasmania. For homes with existing PV, a solar hot water vs electric hot water comparison can be quite close, with timers and solar diversion helping an electric unit behave like a solar hot water heating system.

Recent data shows 53 efficient hot water installations (heat pump and solar) recorded in the Rokeby postcode, with a clear peak around 2011 when 23 systems went in, and solid activity in 2010 and the following few years. While installations have been quieter more recently, that earlier wave of upgrades shows strong local interest in electrification, lower running costs and more efficient hot water TAS wide. Many of those early systems are now approaching replacement age, so solar hot water tank replacement and hot water repair work is becoming more common.

Hot Water Rebates, Tariffs & Savings

Across Rokeby there is growing interest in replacing tired gas or electric units with efficient options like a heat pump hot water system, a modern electric hot water system or a rooftop‑boosted solar hot water system. Homeowners can usually tap into a mix of Australian Government incentives (such as Small‑scale Technology Certificates on eligible heat pump and solar hot water systems) plus state‑based hot water rebate TAS programs that effectively reduce the hot water system price or cost at the point of sale. A solar hot water rebate or heat pump hot water rebate can knock a substantial percentage off the upfront heat pump hot water price or cost or solar hot water price or cost, bringing quality brands within reach.

When you combine rebates with good tariffs and, ideally, rooftop solar, many Rokeby households see payback periods shrink to just a handful of years, with typical savings of hundreds of dollars a year. Choosing the most efficient hot water system for your situation, setting timers to run when solar is exporting, and comparing electric hot water vs gas hot water carefully can all help you get the best result from an energy efficient hot water system. For some homes, especially renters and community housing, an electric hot water system rebate can also help move away from ageing gas units without a big cash outlay.
