SOLUTION
Air Source Water Heaters - Heat Pump is a safe hot water supplying device and absolute power savings of up to 70 to 80% of electricity consumed by the device performance reaches 400%.
Compare the efficiency of heat pump solution with others
With a asssumption of a 50 rooms hotel has an average of one guest per room, each guest takes a shower once a day, and uses 50 liters of water for each. In this case we assume that the guests use only shower. In actual they can use the bath which will be costed more water (about 150 - 350 liters).
Plan 1: Using heat pump
75,000L x 10kw = 750kw x 2,000VND/kw ≈ 1,400,000 VND/month
Plan 2: Using 20-30 liters Electrical Heater
75,000L x 60kw = 4.500kw x 2,000VND/kw ≈ 9,000,000 VND/month
Plan 3: Using Diezel Boiler
75,000L x 16 Liters = 1,200Liters x 15,000 VND/Liters ≈ 18,000,000 VND/month
Phương Án 4: Using Gas Boiler
75,000L x 10 Kg = 750kg x 23,000VND/kg ≈ 17,250,000 VND/month
With plan 2,3,4, customer have to pay other annual costs such as: operator salary, fuel, fire risk,…
COMPARISION TABLE
| Plan | Technology | Costs Calculating | Annual Costs |
|---|---|---|---|
| 1 | Heat Pump | 1,400,000 VND/month x 12 | 16,800,000 VND/year |
| 2 | Electronic Heater | 9,000,000 VND/month x 12 | 108,000,000 VND/year |
| 3 | Diezel Boiler | 18,000,000 VND/month x 12 | 216,000,000 VND/year |
| 4 | Gas Boiler | 17,250,000 VND/month x 12 | 207,000,000 VND/year |
CONCLUSION
Customer can save more than 150,000,000 VND annual if using new technology heating system - heat pump.
