⚠️ Think your solar system is covering your hot water? Think again.
A recent MyBroadband article highlights a surprising issue: many homes with solar are still using grid electricity to heat their geysers — often without realizing it.
Here’s why 👇
👉 Electric geysers are one of the biggest power hogs in your home, sometimes using a massive portion of your solar capacity ()
👉 If your system isn’t perfectly configured (or during cloudy weather / early mornings), your geyser quietly switches back to grid power
👉 That means your “solar savings” are leaking away every day
💡 So what’s the smarter solution?
🔥 Go gas for your hot water
Instead of forcing your solar system to handle a high-load electric geyser:
✅ True energy independence – gas doesn’t rely on sun, batteries, or grid backup
✅ Lower solar system costs – no need to oversize panels or batteries just to heat water
✅ Hot water anytime – even at night, during load shedding, or on cloudy days
✅ Better efficiency – electric geysers convert expensive electricity into heat, while gas does it directly and instantly
In fact, trying to run a standard electric geyser on solar often requires system upgrades or careful scheduling just to avoid drawing grid power ()
🚀 Bottom line:
Use your solar power for what it does best (lights, appliances, savings) — and let gas handle your hot water reliably and efficiently.
