Heat Tech Heat Pump Regassing in Dunkeld

Heat Tech heat pump regassing in Dunkeld. Locally supported domestic plant with readily available spares.

Heat Tech equipment we work on includes geysers and hot water heat pumps. Commonly replaced parts on this brand are elements, thermostats, anodes, and we keep or source these against the unit's model and serial plate rather than by guesswork.

A heat pump is a sealed system: if it is short of gas, there is a leak. Simply topping up sends the same refrigerant back into the atmosphere within months and masks the fault. We pressure-test, trace the leak, repair it, evacuate to vacuum and then charge by weight to the manufacturer's plate data.

Dunkeld is a high-value residential pocket of Rosebank, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Dunkeld falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
