Job required: * Disconnect the existing hot water system from the controlled-load circuit. * Connect it to the general usage circuit. * Install a suitable timer/controller so the hot water operates during solar production hours (ideally around 10am–2pm). * Check that everything is safely and correctly connected and compliant with NSW electrical requirements.

Disconnect and remove 2 solar hot water heaters

$250

Neutral Bay NSW 2089, Australia

27th Jul 2026

These solar hot water heaters (not powered, just has water running through it) are rusty and leaking, I need to decommission and remove. Each heater panel is about 2x1m. I am fit and able to help lift, but I can’t do it alone; ideally I need a plumber who can disconnect / block off the pipes from the internal HSW. All i really need is for someone to disconnect it at the source, and then help me get it off the roof. I’ll do the rest. Flat room, easy access.

Brilliant work, helped me solve a lot of problems as we went. Very professional. Thank you ☺️
