Hot water booster/timer modification

$10

Cringila NSW 2502, Australia

6th Oct 2026

I have an existing solar hot-water system with an electric booster currently connected to Controlled Load/off-peak. I also have rooftop solar PV and would like a simple, cost-effective solution to allow the hot-water booster to run during the day using my normal household supply/solar generation rather than having to wait for the off-peak period. Ideally, I’m looking for a straightforward timer setup with a manual override/boost option when required. The existing solar hot-water system is working and I’m not looking to replace it or install an expensive solar diverter. Looking for a licensed electrician to check the existing setup and make the modification if suitable.

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 ☺️
