Start with the local property, not a generic BTU chart
Stellenbosch combines heritage-sensitive central streets, high-turnover student accommodation and substantial residential growth on the town’s edges. Each creates a different priority: discreet pipework, robust simple controls or integrated planning in a newer home.
Landlords may value tamper-resistant, easy-to-service equipment, while owner-occupied estates often prioritise low noise and a clean exterior. Heritage or body-corporate constraints should be resolved before drilling begins.
