Analysis of the flexibility potential of low temperature heat pumps for the space heating of residential buildings by underfloor heating

Abstract

This work attempts to evaluate the flexibility potential of residential buildings heated by low temperature heat pumps and equipped with floor heating in Belgium. The aim is to understand the relevance, the advantages and drawbacks of the strategy on different configurations. A single zone dynamic building model with a heat pump model is developed, and three cases are investigated: the time period of storage/discharge of heat in the building, the possibility to increase self-consumption of a photovoltaic installation and the economic interest thereof in Belgium, and the potential heat load that can be shifted from peak to off-peak hours in a dynamic pricing context.
