Low-emissions heating, cooling and hot water system

A hydronic system, comprising:

• a control unit, comprising:
• a memory comprising stored instructions;
• and
• a processor configured to execute the stored instructions to cause the control unit to perform at least:
• monitoring, a volume of hot water in a hot storage tank via a first set of flowmeters;
• monitoring, a volume of chilled water in a cold storage tank via a second set of flowmeters;
• monitoring, a first outlet temperature of the hot water within the hot storage tank via a first temperature sensor and a second outlet temperature of the chilled water within the cold storage tank via a second temperature sensor;
• and
• operating, a heat pump unit for recharging the hot water and the chilled water within the hot storage tank and the cold storage tank respectively, the heat pump unit operated when a respective predetermined limit reaches for at least one of:
• the volume of the hot water,
• the volume of the chilled water,
• the first outlet temperature, and
• the second outlet temperature,
• wherein for operating the heat pump unit for recharging the hot water and the chilled water, the control unit is caused to perform at least one of:
• selectively operating the heat pump unit based on a cost, emissions and a schedule of operation of a power source for recharging the hot water, when at least one of the volume of hot water and the first outlet temperature have reached a respective predetermined limit, and
• selectively operating the heat pump unit based on a cost, emissions and a schedule of operation of a power source for recharging the chilled water, when at least one of the volume of chilled water and the second outlet temperature have reached a respective predetermined limit.
