Hot-water faults have different causes
A gas geyser may function well at one basin but struggle when two bathrooms use hot water together. That does not automatically mean a major fault: heater capacity, mixed-water demand and the unit’s control response all matter. We begin by establishing when the problem appears.
Running two showers at the same time
Instantaneous water heaters have a rated delivery capacity under specified conditions. A home with simultaneous bathrooms can demand more hot water than a smaller unit can provide at the chosen temperature. We ask if one outlet works correctly on its own and whether the issue existed from installation or developed recently. Capacity and faults should not be confused.
The heater fires, then stops when another tap opens
Changes in pressure and flow can affect a water heater’s control sequence. Some units shut down if operating conditions move outside the required range. We ask whether the display reports an error and if the flame visibly extinguishes, while leaving internal diagnosis to appropriately qualified personnel.
Inconsistent temperature while washing dishes
Short, repeated tap openings can cause an instantaneous heater to start and stop more often than a steady shower. Low-flow fixtures or mixer settings can influence behaviour. We examine whether the symptom occurs only during brief use, because this can differ from an ignition failure during sustained demand.
Battery ignition and electrically controlled heaters
Some gas geysers use replaceable batteries for ignition; others use mains-powered electronics or different arrangements. A unit that is completely silent needs a different investigation from one that clicks repeatedly but does not establish flame. Identify the model before assuming any particular battery or controller is fitted.
Water leaks around the geyser
Moisture below a heater may be coming from a connection, condensation or the water-side assembly, each needing distinct attention. A leak should not be dismissed because the flame still lights. We ask where the water appears and whether it happens during heating or continuously; avoid removing the cabinet to inspect internal gas connections.
Combustion air and installation position
An appliance designed for one mounting environment should not be relocated into an enclosed utility space simply to shield it from weather. The instructions for that exact type, air supply and flue arrangement matter. Where any installation correction is required, the appropriate registered practitioner and documentation are essential.
Choosing repair versus replacement
We consider the age and condition of the heat exchanger, control system and accessible model-specific parts. A worn sensor may be repairable; a damaged heat exchanger or obsolete safety component can make further repairs uneconomical or inappropriate. The decision should follow diagnosis rather than a generic replacement recommendation.
Your Brackenhurst booking details
Describe how many bathrooms draw from the heater, whether demand at one tap differs from two, and how long the water stays hot. Include photos of the appliance label and installation position taken without touching gas pipework. Mention any recent change to shower heads or plumbing if the timing matches the problem.
Questions about this repair
Can one gas geyser supply two showers?
That depends on the unit’s rated capacity, water conditions and the flow demanded by both outlets.
Why does the geyser stop when a second tap opens?
Flow and pressure changes can affect heater operation; the specific cause needs diagnosis.
Is a leaking gas geyser always beyond repair?
No. The source of the water and the condition of the unit determine the repair options.
