Hot water systems in Montgomery

Across Montgomery and the 3851 area, more households are rethinking their old gas and electric hot water system and switching to energy efficient options. With an average household size of around 2.3 people and more than 1,800 owner-occupied homes, a reliable, low-running-cost hot water installation makes a real difference to weekly budgets. Many families here are on a median household income of about $1,120 a week, so shaving hundreds off power bills with a modern solar hot water system, heat pump hot water system or efficient electric hot water system is a logical next step.

Montgomery is well suited to efficient hot water upgrades. The local climate records an average annual solar exposure of about 15.3 MJ/m² per day – roughly 4.25 kWh/m² – which is strong support for both a solar hot water heating system and a high-performance heat pump hot water system. That solar resource, combined with rising energy costs, makes upgrading from older gas hot water to an energy efficient hot water system one of the easiest ways to cut household emissions and running costs. Over the life of the unit, Annual Hot Water Energy Savings can easily reach thousands of dollars for Montgomery homeowners.

In a postcode with more than 2,100 occupied dwellings and a relatively older population (median age 47, with a large over‑65 group), hot water reliability matters. Many homes are three‑bedroom separate houses, so hot water demand is steady rather than extreme, which suits a well-sized heat pump hot water installation or solar hot water installation perfectly. Brands like Rheem heat pump hot water, Rinnai solar hot water, Sanden heat pump and Chromagen solar hot water are all popular choices for those chasing the most efficient hot water system and low noise, long warranties and solid after-sales support.

For a typical Montgomery home, the right upgrade can deliver meaningful savings compared with an older system:

• Old electric to heat pump: around $350–$700 a year off bills
• Gas to heat pump: roughly $300–$600 a year in savings
• Gas to solar hot water: about $250–$550 a year saved
• Old electric to modern electric hot water with rooftop solar: often $250–$500 a year

Locally, efficient hot water is no longer a niche choice. In the 3851 area, there have already been 347 efficient hot water systems installed, combining both heat pump and solar hot water. Installations picked up around 2009–2014, with a standout year in 2011, and have stayed solid right through to 2024 and 2025. That steady stream of hot water installation and hot water repair work reflects growing interest in electrification, lower running costs and moving away from gas. It also shows that more Montgomery residents are comparing heat pump vs solar hot water, and even solar hot water vs electric hot water, to find the best hot water system Australia can offer for their situation.

Hot Water Rebates, Tariffs & Savings

For Montgomery households, the combination of local sunshine, rising power prices and generous incentives makes efficient hot water upgrades very attractive. Even if you are simply replacing a tired electric unit with a new electric hot water installation, it is worth exploring whether a heat pump hot water system or solar hot water system could be fitted instead, particularly if you already have rooftop solar.

Australian Federal Government incentives, such as Small-scale Technology Certificates (STCs), can reduce the upfront solar hot water price / cost or heat pump hot water price / cost. On top of that, Victorian hot water rebate VIC programs often include a specific heat pump hot water rebate, solar hot water rebate and sometimes an electric hot water system rebate when moving away from gas. These discounts can effectively knock a substantial percentage off the installed hot water system price / cost, shortening the payback period to just a few years, especially when you use timers or solar diversion to run the system when your PV is generating.

With the right advice, Montgomery homeowners can choose between options like Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or other candidates for best heat pump hot water system, and match them to their tariff and household pattern. That way, your energy efficient hot water system quietly does its job in the background while your bills stay low.
