| Comparison |
|
|
The system of vacuum hot water boiler is more simple,safe and has higher efficiency comparing with the system of other traditional commercial boiler.
Compare with steam boiler
| Item |
Vacuum Hot Water Boiler |
Steam Boiler |
| Safety |
Absolutely safe(under vacuum status) |
High pressure of furnace,so explosion is possible |
| The way of supplying hot water |
The unit can supply hot water directly |
The boiler generates steam first then generate hot water through heat-exchanger |
| Equipment Accessories |
Heat-exchanger inside.No more accessories. |
Need softener,heat-exchanger etc. |
| Installation Demand |
Connect with external pipes, very easy |
Complicated |
| Life-span |
More than 20 years |
Scale is easy to be produced.Less than 10 years in general |
| Efficiency |
>92% |
<85% |
| Running Expenses |
Save 30% of running expenses less than steam boiler |
Heat-exchanger thermal loss is about 30% |
| Running Maintenance |
Auto-running without professional people.No annual inspection,low maintenance |
Professional people who have licence.Need annual inspection.High maintenance. |
Compare with other hot water boiler
| Item |
Vacuum Hot Water Boiler |
Other Hot Water Boiler |
| Safety |
Guarantee no explosion.No register and annual inspecion. |
Safety.Need register to install. |
| Thermal Efficiency |
More than 92%.No efficiency decline. |
Less than 90% in general,and efficiency will decline year after year. |
| Life-span |
More than 20year. |
8-10 years. |
| Investment |
Connect with external pipes,low investment. |
High initial investment,need heat-exchanger,softener,water circulate pump and so on. |
| Scale And Rust |
No scale and rust. |
Have scale and rust. |
| Production Demand |
High |
Low and easy |
| Installation Demand |
Low |
High initial investment,need heat-exchanger,softener,water circulate pump and so on. |
| Boiler Room |
Minimize room space |
Large(complicated system) |
| Running Expense |
Save expenses.The medium water never need be added,no scale,high efficiency. |
1.Low expenses at initial stage but increase year after year.2.The temperature of medium water>90¡æ,the loss of evaporation is large. |
