Hot Water Systems in Sandton & Northern Johannesburg

Hot water is the biggest single line on most Johannesburg electricity bills — a conventional electric geyser can account for around 40% of household consumption. Choosing the right hot water system is therefore the highest-impact plumbing decision you'll make. Apple Plumbing & Electrical supplies, installs and repairs every type of hot water system across Sandton, Midrand, Fourways and Bryanston: standard electric geysers, solar geysers, air-source heat pumps and LPG gas units. We help you pick the right one for your roof, household size and budget, install it to SANS 10254 with drip tray, vacuum breakers and isolator, and issue the Plumbing COC. Owner-managed, with same-week installation in most suburbs.

What we do

We work across the full range of hot water systems so our advice isn't tied to one product. Electric geysers: like-for-like replacements and upgrades with energy-saving Geyserwise scheduling. Solar geysers: SABS-approved direct and indirect (split) systems that cut hot-water electricity by 60–70%, sized to your roof and household. Heat pumps: air-source units that use roughly a third of a geyser's electricity and suit space-constrained townhouses where a solar array won't fit. Gas geysers: instant LPG hot water that keeps working through load-shedding, installed with a gas Certificate of Conformity. Every installation includes the compliant safety kit — drip tray, vacuum breakers, T&P valve, isolator and correctly piped overflow — plus a Plumbing COC. We also repair and service all of these: elements, thermostats, pressure valves, solar controllers and heat-pump faults, usually on the first visit because we stock the common spares.

Signs you need this service

• Your geyser dominates your monthly electricity bill
• An ageing electric geyser due for replacement (upgrade once)
• No roof space for solar panels — a heat pump may suit
• You want hot water that survives load-shedding (gas)
• Selling or insuring — you need a compliant install with COC
• No hot water, or a geyser leaking from the overflow
