This paper investigates how advanced HVAC systems and predictive control can influence the interaction between a house and the grid. The case study corresponds to a house in Toronto, Ontario, Canada, analysed during the heating season. The following scenarios are considered: (a) an air-to-air heat pump for heating regulated through a conventional rule base control (RBC); (b) an air-towater heat pump, also using RBC, linked to a radiant floor system; (c) an air-to-water heat pump with a predictive control strategy under time-of-use (TOU) pricing; (d) the same system and control approach, using a real-time pricing curve. Results are examined in terms of energy use, cost, and load matching / grid interaction metrics.
