Across the 5700 postcode there have already been around 840 efficient hot water installations, combining heat pump and solar hot water installation projects. Install numbers climbed sharply in years like 2003, 2010 and 2015, and while recent years show fewer systems going in, there is renewed interest as people look to electrify, move away from gas hot water and take advantage of new rebates. These hot water installation trends show Mundallio residents are steadily embracing efficient hot water technology to lower bills and future proof their homes.

For a typical Mundallio home, hot water demand is steady rather than extreme, which means a correctly sized system can easily cover daily needs. Many locals are comparing heat pump vs solar hot water, or even solar hot water vs electric hot water, to find the most efficient hot water system for their roof space, budget and tariff. Trusted brands like Rheem, Rinnai, Sanden and Thermann are common options locally, whether you are looking at a rheem solar hot water package, rheem heat pump hot water, rinnai solar hot water or a premium sanden heat pump for maximum efficiency.

When people start getting quotes, they naturally ask about hot water system price and solar hot water price, as well as the heat pump hot water price for different sizes. While every property is different, Mundallio homeowners can often expect meaningful savings by upgrading:

• Old electric to heat pump hot water system: around $350–$700 a year off bills. • Gas to heat pump hot water installation: around $300–$600 a year saved. • Gas to solar hot water installation: around $250–$550 a year saved. • Old electric to modern electric hot water installation with good solar: around $200–$450 a year saved.

These figures depend on how much hot water you use, your tariff, and whether you run the system during the day to soak up solar. Using timers or a smart controller with solar diversion can turn your system into a highly energy efficient hot water system, especially if you are aiming for an all electric home.

Hot Water Rebates, Tariffs & Savings

There is growing interest in Mundallio in replacing old gas or electric units with heat pumps, newer electric hot water systems or a solar hot water system to cut bills and emissions.
