Claim:
1. A method of cooling a building, the method comprising: using a blower to create an air flow through an air duct in the building, the air flow to be directed into the building; providing an air conditioning system with an evaporator in the air duct, the air conditioning system operative to cool the air flow in the air duct as the air flow passes the evaporator; providing a radiant heating apparatus comprising: operating the air conditioning system and the radiant heating system in a first state by cooling the air flow in the air duct using the air conditioning system and passing the cooled air flow through the air-to-fluid heat exchanger before the air flow is discharged into the building so that the cooled air flow cools the liquid circulating through the air-to-fluid heat exchanger and the cooled liquid being circulated through the radiant heating loop cools the thermal store; and when the thermal store is cooler than an ambient temperature in the building, operating the air condition system and the radiant heating system in a second state by turning off the air conditioning system so that the air flow through the air duct is at substantially the ambient temperature, circulating the liquid cooled by the thermal store through the radiant heating apparatus and cooling the air flow by passing the air flow through the air-to-fluid heat exchanger as the cooled liquid passes through the air-to-fluid heat exchanger before discharging the air flow into the building.
