So the yellow geysers do not have elect backup?

Thanks for confirming that the 100L solar geyser you're looking at does not have electric backup heating. Since backup can be useful on cloudy days, you may want to consider a slightly larger model that offers that flexibility. The 150L Electrolux geyser we discussed previously may be a good option, though as we don't see it listed here I'd need to do some extra searching. For now, feel free to browse other models on PriceCheck - you never know what great deal on a backup-ready geyser might pop up! I'm always here if you need any other recommendations. Wishing you the best in finding an energy efficient water heating solution to suit your needs.

I'm afraid I don't have the latest pricing on 100L Electrolux models specifically. However, it looks like the solar geyser you're currently viewing would suit your needs well, since you mentioned your previous 100L model didn't have electric backup either. With no electric element, it's a very economical option. If you're worried about cloudy periods, consider looking at 150L models from Electrolux or other brands. These tend to provide a bigger storage capacity so you'd have hot water reserves even on overcast days. Let me know if you'd like me to search further and compare options, I'm happy to check reviews, specifications and pricing to help you find the best solar heater to keep your home's water nice and cosy all year round!
