Two Caloundras, Two Sets of Hot Water Problems
Caloundra is the southern anchor of the Sunshine Coast, and it is currently undergoing the largest change of any locality in the region. The coastal suburbs (Kings Beach, Moffat Beach, Shelly Beach, Golden Beach) are long-established, with a substantial stock of post-war beach houses and 1960s to 1980s low-rise unit blocks. Inland and to the west, the Aura development at Caloundra South is building an entirely new city on greenfield land, with suburbs including Baringa and Nirimba delivered as master-planned, all-electric estates.
Those two halves generate opposite service problems. In the old suburbs, systems are ageing in marine air: corroded casings, seized valves, depleted anodes, and units wedged into side setbacks so narrow that removal is half the labour. Many of these installations also predate current delivery-temperature rules, so replacements must add a tempering valve the owner never budgeted for.
In the new estates, the constraint is design rather than decay. There is no reticulated natural gas, so every home is electric, which means the meaningful choice is between resistive storage and a heat pump. Compact lot sizes put neighbouring dwellings close together, so heat pump compressor placement genuinely matters for noise, and estate design guidelines can restrict where external plant is visible from the street.
RCM Hot Water handles both. In the old suburbs, that means salt-aware servicing intervals and honest assessment of whether a corroded unit is worth repairing. In the new ones, it means siting a heat pump where it performs and does not create a neighbour complaint, and being straight about payback periods, so hot water systems in Caloundra suit the half of the city you actually live in.
