With a high proportion of homes owned with a mortgage and solid median household incomes, many Kalkallo households are looking for smart, future-proof upgrades rather than just the cheapest hot water system price on the day. Local installers are seeing strong interest in heat pump vs solar hot water comparisons, as residents weigh up which is the most efficient hot water system for their roof space, tariffs and lifestyle. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular options, along with Chromagen solar hot water for roof-mounted systems.
In the 3064 area, efficient hot water is becoming the norm rather than the exception. With families making up a large share of the population, continuous hot water demand is high, so the hot water system cost over its lifetime really matters.
