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 Green Lake and the 3401 area, 279 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 Green Lake's climate delivering an average of 4.7 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 Green Lake
Across Green Lake and the wider 3401 area, more households are rethinking their hot water system and moving away from old gas or power‑hungry electric units. With an average household size of around 2.7 people and mostly separate houses (over 1,500 dwellings, many owned outright or with a mortgage), families here use a lot of hot water for showers, washing and everyday living. Power prices keep rising, so upgrading to an energy efficient hot water system is becoming the logical next step.
Green Lake is well suited to both a solar hot water system and a heat pump hot water system. The local climate data shows mean daily solar exposure of about 16.9 MJ/m², which is roughly 4.7 kWh of sunshine per square metre per day over the year. That strong sunlight helps a solar hot water heating system work efficiently and also boosts the performance of heat pump hot water, especially when paired with rooftop solar. For many Green Lake homeowners, swapping an older gas or electric hot water system for a modern heat pump or efficient electric hot water system can cut annual hot water energy use by more than half.
With a mix of young families (over 400 families with children under 15) and a good number of over‑65s, demand ranges from compact systems for couples through to larger units for four‑bedroom homes. Hot water can easily account for 20–30% of a household’s energy bill, so choosing the most efficient hot water system really matters. Locals are comparing heat pump vs solar hot water, solar hot water vs electric hot water and even electric hot water vs gas hot water to see what stacks up on running costs and comfort.
Typical annual bill savings in Green Lake look like this:
• Old electric to heat pump hot water installation: save roughly $400–$800 per year. • Gas to heat pump hot water system: save around $300–$600 per year. • Gas to solar hot water installation: save about $250–$600 per year. • Old electric to modern electric hot water installation powered by good rooftop solar: save roughly $300–$700 per year.
