Heat Pumps in Boston

Boston sits between Bellville CBD and the Tyger Valley corridor, with student accommodation, small offices, food outlets and residential density. High-occupancy buildings and shared plant dominate the work, with an emphasis on hot water and continuous cooling.

Commercial heat pump installation and repair for hotels, kitchens, gyms and residential estates. Sized on litres-per-peak-hour draw-off rather than tank volume, with element backup retained for worst-case winter mornings.

Output band

3kW – 90kW cascade

Typical saving

60–70% vs resistive elements

COP design point

Rated at Cape winter ambient, not 20°C

Integration

Retrofits onto existing storage tanks

Scope for Boston sites

• 01Draw-off profiling across breakfast, shift-change and evening peaks
• 02Cascade configuration with lead/lag rotation
• 03Legionella-safe pasteurisation cycles
• 04Defrost strategy for cold, damp Tygerberg mornings
• 05Metering so the saving is provable, not promised

Faults we correct across Boston

• —Units installed in unventilated plant rooms recycling cold air
• —No element backup, leaving guests cold on the first frost
• —Tank stratification destroyed by badly placed return legs
