Heat Pump Regassing in Midstream
Heat Pump Regassing in Midstream covers leak detection first, then correct-charge regassing by weight. Newer estate housing with standardised heat pump and geyser installations.
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.
The installed base here is mostly domestic and estate housing, so work concentrates on single units, multi-geyser homes and shared complex plant. Warranty-aligned servicing keeps estate installations covered.
Midrand and Centurion sit between the Johannesburg and Pretoria routes, so attendance windows are usually the shortest of any area. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance. Recovery rate and storage volume have to be considered together; adding heating capacity to undersized storage rarely fixes a peak-hour shortfall.
