Implication

Randomized trial investigates cost savings and energy flexibility in residential heat pump systems, suggesting operational adjustments enhance economic performance.

Key Points

This research examines the effectiveness of thermal energy storage in residential air-to-water heat pumps to optimize energy costs.
Hourly simulations over eight years using meteorological data from multiple continental locations.
Two configurations analyzed: one with and one without thermal energy storage.
A simple rule-based control strategy was implemented focusing on practical applicability.
Electricity cost reductions of 19–23% were achieved due to thermal energy storage across all years and locations.
Payback period for the investment in thermal energy storage remains long, at approximately 20 years.
No significant seasonal performance changes were noted despite load shifting.
