Hot water systems in Navan
Around Navan, more homeowners are rethinking their old gas and electric hot water system and switching to energy efficient hot water. With most of the 508 local dwellings being separate houses and an average household size of 2.1 people, a reliable, low running cost hot water upgrade makes a lot of sense.

Navan’s climate is ideal for modern hot water technology. The nearby Riverton weather station records an average annual solar exposure of about 17.6 MJ/m² a day – roughly 4.9 kWh/m² – which is excellent for both a solar hot water system and a heat pump hot water system. That strong sunshine helps a solar hot water heating system or heat pump hot water run efficiently, especially if you already have rooftop solar. Swapping from older gas or electric hot water to an energy efficient hot water system can trim a big chunk off your household energy use, with annual hot water energy savings often reaching hundreds of dollars.
In 5412, most homes are three‑bedroom places with couples or older residents, so hot water demand is steady rather than extreme, but long showers and laundry still add up. Efficient hot water systems like Rheem heat pump hot water, Sanden heat pump units, and roof‑mounted brands such as Solahart or Chromagen solar hot water are increasingly common options when people look for the best hot water system Australia can offer. Many locals are also weighing up heat pump vs solar hot water and asking how a modern electric hot water system compares.
Typical annual bill savings in Navan look like this:
• Old electric to heat pump hot water installation: save about $350–$700 per year. • Gas to heat pump hot water: save roughly $250–$600 per year. • Gas to solar hot water installation: save about $300–$650 per year. • Old electric to new electric hot water installation with rooftop solar: save around $250–$500 per year.

That pattern shows growing interest in electrification, lower running costs and moving away from gas hot water as systems reach the end of their life.
Hot Water Rebates, Tariffs & Savings
Across Navan and regional SA, more households are replacing tired gas or electric units with a heat pump hot water system, solar hot water or a high‑efficiency electric hot water system. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that reduces the upfront hot water system price. South Australian schemes can also support an electric hot water system rebate or specific heat pump incentives. Combined, these hot water rebate SA programs can trim the heat pump hot water price or solar hot water price by a substantial percentage. When you factor in bill savings of a few hundred dollars a year, payback periods can fall to just a handful of years, especially if you use timers or solar diversion so your hot water runs mostly on your own solar.
Whether you are comparing electric hot water vs gas hot water, solar hot water vs electric hot water, or wondering which is the most efficient hot water system for your place, it pays to look at the full hot water system cost over its life – not just the purchase price.
