Electric geysers, solar geysers and heat pumps installed, replaced and repaired by a plumber who is qualified for all three.

A geyser is a pressure vessel holding water at up to 90 degrees. The installation has to include the correct pressure control valve, safety valve, vacuum breakers, drip tray and overflow, all in the right positions, or it becomes a risk to the house and the people in it. H.B. Plumbing is PIRB registered, which is the industry body that regulates geyser installations in South Africa.
Hanco is qualified for both solar geyser systems and heat pumps. Both cut the electricity a household spends on hot water, which is typically the single largest item on a South African home's power bill. Which one suits you depends on roof orientation, available space, household size and budget. Hanco assesses the house and recommends the option that pays back fastest.
A straight replacement of an existing geyser with the same size unit in an accessible roof space is normally completed in a single visit. A new installation, a relocation, or a solar or heat pump system takes longer because of the extra pipework, mounting and electrical coordination. You get a clear time estimate before work starts.
Close the cold water supply to the geyser, switch off the geyser at the distribution board, and call 072 244 2165. Use the emergency checklist below to walk through it step by step.
Tap each step as you do it.
The isolation valve is usually a lever tap on the cold pipe near the geyser, like the green-handled valves in our photo. Turn it a quarter turn so it sits across the pipe.
Find the breaker or isolator marked geyser and switch it off. Never leave a geyser powered with no water in it.
Open the nearest hot tap. It will slow to a trickle once the pressure is off.
Ceilings can sag and drip for a while after the supply is closed. Clear the area underneath.
Send a photo of the geyser and the drip tray if you can reach it safely.
No call centre, no forms to fill in. Send a photo of your geyser, bathroom or leak on WhatsApp and Hanco takes it from there.
