Mandemar’s climate is well suited to efficient hot water upgrades. Local solar exposure averages about 16 MJ/m² per day, which is roughly 4.4 kWh/m² – strong enough to support both a well‑designed solar hot water system and a quality heat pump hot water system. For many homeowners, upgrading from an older gas or resistive electric hot water system to an energy efficient hot water system is the logical next step after installing rooftop solar, delivering solid annual hot water energy savings.
The area is dominated by separate houses, with more than 4,800 three‑bedroom‑plus homes, so hot water demand is typically medium to high. That makes choosing the most efficient hot water system even more important. A modern heat pump hot water system or solar hot water heating system can dramatically reduce the share of your power bill taken up by hot water, especially if you already have solar and can time your hot water installation to run during the day.
Typical annual bill savings in Mandemar for a correctly sized system might look like:
• Old electric to heat pump hot water installation: save around $400–$800 per year. • Gas to heat pump vs solar hot water: often $300–$700 per year, depending on tariffs. • Gas to solar hot water installation: around $300–$600 per year. • Old electric to modern electric hot water installation with solar: $250–$500 per year using daytime solar.
Local homeowners are choosing trusted brands such as Rheem heat pump hot water and Rheem solar hot water for proven reliability, while Rinnai solar hot water and Sanden heat pump systems are popular for those chasing the best heat pump hot water system performance and very low running costs.
