A room heating method using an air conditioner with a thermal storage floor heating system is proposed. The floor heating system is composed of 32 polyethylene tanks 672l capacity and vinyl tube of 200m in length under the floord (10 m^2). The water heated by solar heat pump flowed though the tube. The floor heating system performances using heat pump with and without PV are compared. The stored calorie of the evaporator decreased 15% by PV. On the case of the evaporator with PV, however, electricity consumption decrease by 14%. As a result, the COP of the system is kept constant. The obtained electric power is about a half of the compressor power consumption.
