Thanks for the search results. Based on your question about power consumption, I would recommend considering the Solo Wall Panel Heater 420W for R599.99 or the Alva 425W Electric Wall Panel Heater for R779. Both of these options are dedicated electric wall heaters that would provide efficient, directed warmth without using too much extra power compared to your current heater. The Solo and Alva products have similar power ratings to your Econo-Heat heater, so your electricity costs should remain about the same. They also have good reviews for heating small spaces effectively. Let me know if you need any other details!
I'm sorry to hear you're disappointed with your current electric heater. Based on the search results, I would suggest either the Solo Wall Panel Heater or the Goldair GPH-600 425W Electric Wall Panel Heater. Both are highly rated electric wall heaters that should provide reliable warmth without using more power than your existing heater. The Solo model is the most affordable option at only R599.99, but the Goldair also has a good price of R669 and may last slightly longer being a more established brand. Both will heat small spaces efficiently without increasing your electricity costs. I hope one of these options would better suit your needs and help you feel warmer this winter. Please let me know if you have any other questions!
