Hot water systems in Coonawarra
In Coonawarra, hot water is a big part of everyday comfort, whether you are running a busy household or a local business in the vines. With power prices rising and many homes still on older gas or electric units, more locals are starting to look at an energy efficient hot water system – especially options like a heat pump hot water system, a solar hot water system, or a modern electric hot water system that works with rooftop solar.
Coonawarra’s climate is well suited to efficient hot water.
