Hot Water Systems in Como

The 2226 postcode, covering Como, Bonnet Bay and Jannali and surrounding areas, is home to around 4,743 households. With many households already generating their own clean solar power, many are now looking at how they can make their entire home energy system more efficient, with hot water heating often the logical next step.

With hot water roughly accounting for a quarter of the average home's energy use, switching to an energy-efficient hot water system is one of the biggest opportunities for savings. Across Como and the 2226 area, 455 homeowners have already switched from older electric storage and gas hot water systems to solar hot water or air-source heat pump systems that draw on clean, renewable power while also claiming the hot water rebates to reduce their hot water heater system cost. These highly-efficient systems not only help cut energy bills but also reduce carbon emissions and improve overall energy independence.

With Como's climate delivering an average of 4.6 kWh/m² per day, conditions are ideal for hot water systems and hybrid heat pump systems that harness both sunlight and ambient air temperature to heat water efficiently all year round. When paired with existing rooftop solar power or solar batteries, the result is hot water that costs far less to run and is powered by clean, self-generated energy.

Hot water systems in Como

Across Como, more homeowners are swapping old gas and ageing electric units for modern, energy efficient hot water systems. With an average household size of 2.8 people and more than 4,500 dwellings across 2226, reliable hot water is non‑negotiable, but power prices are pushing many families to rethink their options. For a suburb where most homes are either owned outright or with a mortgage, upgrading to a smarter hot water system is a logical way to protect the household budget.

Como’s sunny climate helps. The local weather station at Oyster Bay records around 16.4 MJ/m² of solar exposure each day on average – roughly 4.5 kWh/m² – which is ideal for both a solar hot water system and a heat pump hot water system. That level of sunshine supports strong performance from a solar hot water heating system and also boosts the efficiency of heat pump hot water, especially when paired with rooftop solar. For many households, the annual hot water energy savings from moving off older gas or resistive electric can reach hundreds of dollars a year.

In 2226, separate houses dominate, with plenty of three‑ and four‑bedroom homes, so hot water demand is solid. Families with teenagers, as well as older couples ageing in place, are looking for the most efficient hot water system they can install without sacrificing comfort. A lot of homes still run gas, but there’s growing interest in electric hot water vs gas hot water as people look to electrify and make use of solar. That’s where options like a Sanden heat pump, Rheem heat pump hot water, or a quality Rheem solar hot water or Rinnai solar hot water system come in, alongside brands such as Solahart and Thermann.

Average annual bill savings in Como will vary with usage, tariffs and whether you already have solar, but typical ranges look like this:

• Old electric to heat pump hot water installation: $400–$900 per year • Gas to heat pump: $300–$700 per year • Gas to solar hot water installation: $250–$600 per year • Old electric to modern electric hot water installation run on rooftop solar: $300–$800 per year

Across Como there have already been 455 efficient hot water installations, combining heat pump and solar hot water systems. Install numbers peaked around the big solar hot water rebate years of 2009–2011, when more than 200 systems went in, and while annual volumes have eased back since, recent years still show steady interest in heat pump hot water installation and solar hot water repair and replacement. This long‑term trend reflects a clear local shift towards electrification, lower running costs and cleaner energy efficient hot water system choices.

Hot Water Rebates, Tariffs & Savings

Como households can tap into a mix of federal and NSW hot water rebate support when upgrading. Eligible heat pump and solar hot water systems create Small‑scale Technology Certificates (STCs), which effectively discount the upfront hot water system price. On top of that, NSW programs can offer a dedicated heat pump hot water rebate or solar hot water rebate for certain homes, while some all‑electric upgrades can access an electric hot water system rebate. Together, these incentives can cut the heat pump hot water price or solar hot water price by a substantial percentage, often trimming payback periods to just a few years when paired with rooftop solar. Using timers or smart controls to run an electric hot water system during solar hours, or adding solar‑diversion, can further reduce the overall hot water system cost of ownership. For many Como families with median household incomes above $2,500 per week, that means an upgrade that pays for itself while improving comfort.

If your current unit is rusty, running out of hot water, or you’re weighing up heat pump vs solar hot water or solar hot water vs electric hot water, it’s a good time to look at options like Rheem solar hot water, Rinnai solar hot water, Chromagen solar hot water, or a premium Sanden heat pump. Whether you need hot water repair, a solar hot water tank replacement, electric hot water installation or full solar hot water repair and upgrade, the best hot water system Australia can offer for your home will depend on roof space, tariffs and how you use hot water.

Como’s strong solar resource and growing interest in sustainability make it a great place to move away from gas and towards efficient hot water nsw solutions. If you’d like to cut bills, reduce emissions and future‑proof your home, it’s worth checking whether a heat pump hot water system, solar hot water system or modern electric hot water system is right for you.
