As per my conversation to Purchasing Manager that already discuss to K. Suthi, old design from Plan Architect Co., Ltd. design for one hot water system per guest room.
It’s absolutely high electricity cost bill.
But new one system is only one heat pump machine for distribute hot water to guest room that why must have new design system.
Anyway, Purchasing Manager already discuss to supplier as well. Supplier can design for us but take too long time more than Plan Architect Co., Ltd. because of they didn’t know about HRB building.
That why , we waiting for new one design plan from Plan Architect Co., Ltd.
