Selection Considerations
For Standalone Efficiency:
iStore 270L – Best COP (400%) with low power draw and compact design.
Emerald 320L – Highest capacity with optional e-heater for backup.
For Solar Homes:
SolarEdge Controller – Maximizes PV self-consumption with zero energy waste.
Emerald "Solar Soaker" – Wi-Fi control to prioritize excess solar.
For Smart Home Integration:
Emerald – Real-time monitoring via app and installer dashboard.
SolarEdge – Part of SolarEdge ecosystem (inverters/batteries).
For Incentives:
iStore/Emerald – Qualify for STCs and regional energy schemes.
All systems reduce energy costs vs traditional electric/gas heaters, with varying strengths in solar synergy, smart controls, and capacity. Heat pumps (iStore/Emerald) suit off-grid or low-PV homes, while SolarEdge optimizes existing PV systems.
