The time for jerseys, fireside chats and hot chocolate is here. Winter and its crisp air have snuck up on us, alerting us not only to an impending wardrobe change, but also a more desperate need for hot showers! Electricity bills can skyrocket in winter, with geysers significantly contributing to the energy usage- on average between 30-50%, according to Eskom.
Your geyser energy usage doesn’t need to be a headache this winter, however – Sustainable.co.za offer a range of geyser efficiency solutions for all budgets:
These tips won’t cost you a cent but help you reduce your electricity bill:
For more energy efficiency install a vertical geyser rather than a horizontal one, they distribute the water more efficiently.
Install the geyser close to hot water points to prevent the water from cooling when it runs to the tap.
Reduce the temperature setting on your geyser thermostat to save up to 10% on your electricity bill. Most geysers’ default temperature is set at 65°C but this can be changed to 50°C for summer and 60°C for winter.
Switch off your geyser when it’s not in use. If you fear that your memory might fail you, set initial reminders to make it a part of your daily routine or only switch it off when you go on holiday.
Showering for an average length of time takes much less electricity than filling up a bath.
Budget: R100 - R 1000
Geyser Blanket & Timer
The simplest way to an efficient geyser is to install a geyser blanket and geyser timer. They are inexpensive and guaranteed to cut your electricity bill:
Product: Sustainable Geyser BlanketPrice: R145.00 (It would take approximately a year to pay back with the reduction of your electricity bill)
Product info: Geyser water temperature typically drops by 1 degree per hour, therefore requiring constant energy to keep it warm. A geyser blanket can cut this energy usage by half.
Product:Ellies Power TimerPrice: R355.00
Product info: The Power Timer offers users daily programmes with 16 on/off settings per day as well as the option for weekly programming. This means the geyser will only come on when you need it – some hours in the morning and then again in the evening.

By insulating your geyser pipes you’ll prevent the water from cooling on the way to the hot water tap. The two meters closest to the geyser are the most important pipes to insulate for optimal efficiency.
Product: Armaflex Pipe Insulation: 6 – 13mmPrice: R 13.16- R 29.72
Product info: The Armaflex pipe insulation has an inbuilt water vapour barrier which prevents moisture from entering, resulting in long term thermal efficiency. 50% Of the heat lost in a home’s hot water pipes occurs within 4 metres of the geyser so we advise insulating all piping around the geyser.
Budget: R 1000 - R 2 000
For a budget of over a thousand to two thousand rand, you can consider investing in higher-end geyser efficiency meters as well as instant water heaters:
Product: Geyserwise MaxPrice: R 1 147, 00Product info: This South African-designed intelligent energy control unitwill help you reduce your electricity bill as well as your carbon footprint.
