How to Switch from Solar Hot Water to Heat Pump in Terrey Hills
Get a site assessment
A licensed installer visits your Terrey Hills home to assess your existing solar hot water system, roof panels, and ground-level space for the heat pump.
Choose your heat pump system
Select a heat pump that matches your household size. Unlike solar hot water, heat pumps sit at ground level and do not need roof access or solar collectors.
Remove solar panels and install heat pump
The old solar collectors are removed from your roof and the storage tank is replaced. The heat pump unit is installed at ground level, freeing up roof space for solar PV if desired.
Claim rebates and enjoy hassle-free hot water
STCs and state rebates reduce your upfront cost. You now have reliable hot water without worrying about cloudy days, roof leaks, or panel maintenance.
