Households in Willowmavin can cut their annual hot water energy use dramatically by moving from older gas or electric hot water to a quality heat pump hot water system or solar hot water system.

Willowmavin is well suited to efficient hot water. The local climate data shows mean daily solar exposure of about 16.10 MJ/m², which is roughly 4.5 kWh/m² per day over the year – strong sunlight that supports both heat pump and solar hot water performance. That means a solar hot water heating system or a high quality heat pump hot water installation can deliver reliable hot water while slashing running costs.

Brands like Rheem heat pump hot water, Rheem solar hot water, Rinnai solar hot water and Sanden heat pump units are common options, along with Chromagen solar hot water in some properties.

  • Gas to solar hot water system: $250–$600 per year
  • Old electric to modern electric hot water system with rooftop solar: $250–$500 per year
