Comparison FAQ
Dux Hot Water is cheaper on average in this comparison, but the real answer depends on whether you need electric, gas, heat pump, solar, or urgent same-day replacement support.
System type, installation complexity, switchboard or gas-line work, rebates, and urgency usually affect the total cost more than a blended average across all systems.
