Note:
1 In Jiangsu, 0.6 ton boiler(400 KWs)s, to compute for 1.44*106 kjs/h(344*103 kcs/h).
2 The coal boiler compute by 750 RMB/T(coal).
3 The oil boiler compute by 5000 RMB/T(oil).
4 The electricity charges calculate by the peak time is 0.988 RMB/degree, the general time is 0.720RMB/degree, and the off-peak time is 0.300 RMB/degree.
Clients
Be applicable to area that different electricity charges by time, for example hospital, hotel, emporium, mansion and other place what have high energy supply and oecumenical request.
1. Heating and hot water supply for hotel, mansion and house
2. Hot water for the restaurant, beauty salon and the laundry shop
3. Hot water for the bathroom and the athletics place
4. Using for cooking, distilled water, disinfecting and heating for hospital and sanatorium
5. The technics using hot water for factory
The characters of electronic boiler
 High thermal efficiency ( more than 98%), free from pollution, have no exhaust gas, sullage waste residue and noise.
No fire and low request of fire protection
 Simple installing and small workload of maintenance
 Automatic don't need full-time circulate a personnel
 Using off-peak time electricity and reduce the expense
 safe protection equipment well-found
 Add and subtract burden by class, the process is stable and high control. |
