One of the best energy-saving hacks for your home is undoubtedly a Geyser Blanket. Hot Water Geysers account for over 30% of our home’s energy budget. For this reason, we need to insulate the Geyser with Thermal Insulation. The traditional so-called Geyser Insulation Blankets are a waste of money as they are 50mm thick low-density products. We only install custom-made Geyser Blankets that work and will save money. Our Geyser blanket of choice is the 135mm Aerolite Insulation.

Types Of Geyser Blankets

The traditional Geyser Insulation is a low-density 50mm Isotherm. Hold that into the air, and you will probably see the light on the other side.

Our Geyser Insulation is higher density 135mm Aerolite or 135mm Knauf Ecose Insulation. These Insulation products have an R-value of 3.78 when installed on the roof. For this reason, it will stop up to 70% of the heat loss.

How Much Electricity Does Your Geyser Use

Electricity will become much more expensive as energy resources to generate electricity on a large scale become scarcer. Everybody must save electricity, not only because of the shortage in generating capacity but also to save money and to protect the environment.

Hot water system (geyser):

Did you know? It takes a 3kW, 150l geyser element to heat the water from 20 ºC to 65 ºC in 2 hours 40 minutes and consumes 8kWh (measurement unit for energy), which amounts to R14.64 at an average cost of R1.83c/kWh. Heat 150l of water by 45 ºC (from 20 ºC to 65 ºC) with a 9kW element will cost the same as a 3kW element. The 9kW element will take a third of the time the 3kW
the element would take. Changing the size of the element will not reduce energy consumption.

An electrical geyser consumes 40% of the entire home’s consumption. The lowering of the temperature, from 70°C to 60°C on average, reduces the cost of supplying hot water by 4.8%. Installing a 135mm Aerolite Geyser Blanket around the geyser and pipes will save 60-80%. One can use water-conserving showerheads, self-closing hot water taps or mixing valves, flow restrictors, and aerators in sink taps to reduce hot water consumption further.
