Electric pool heater SET I-SILENT 10-15

for in-ground swimming poolsfor above-ground pools

Overview
SET i-Silent inverter heat pumps are engineered for heating small to medium outdoor and indoor swimming pools and spas. They provide high heating output with low energy consumption — about half the energy of conventional on/off pool heat pumps and roughly one tenth of gas or electric heaters. Units use R32 refrigerant, require no fuel storage and emit no fumes. Rated to operate down to -10 °C, i-Silent models extend the pool season while ensuring quiet, reliable and flexible operation.

Key features

• Inverter heat pump (variable-speed compressor)
• Average COP 9.7 — approximately 2× more efficient than on/off heat pumps
• Eco-friendly refrigerant R32 (low GWP: 675)
• Performance range: 10.2 to 14.1 kW depending on model
• Whisper Mode: 9–11 dB(A) noise reduction versus equivalent on/off units
• Multifunction operation: heating, heat/cool and cooling modes

New refrigerant gas

• Low global warming potential (GWP 675)
• Zero ozone depletion potential (ODP = 0)
• Compliant with F-gas phase-down requirements
• Requires less refrigerant per kW and is easier to recover/recycle

Benefits

• All-year heating capability for outdoor and indoor pools
• Operates down to -10 °C ambient temperature
