Why your geyser heats slowly in Sam
At 870 ppm, calcium carbonate deposits on your geyser's heating element within the first year of regular use. The element has to push more electricity through a mineral coating to heat the same water - you notice this as slower heat-up and higher electricity bills.
Geyser descaling every every 2 months is appropriate for 870 ppm. For a storage geyser: drain the tank, introduce an acid descaling solution, allow 3-4 hours, flush with 3 full tank volumes.
