    Comparison of heating system
        2009-06-11 View:　Editer： [close]
      Heating system of heating cable Central heating Wall-mounted gas furnace
    Environmental pollution None When burning, oxygen consumption is great; exhaust gas and peculiar smell is emitted. Coal piles, clinker and soot lead to environmental pollution. Boiler circulating pump sends off loud noise, and the system has hydrodynamic noise. When coal is burning, exhaust gas and noise pollute the nvironment.
    Life It has the same life as the building A new furnace is needed every 10—12 years. A new furnace is needed every 10 years, and a new heater core is needed every 3 years.
    Security The system is stable and reliable, without hidden threat against safety. Good security Somewhat dangerous.
    Maintenance No need of maintenance on the whole. Low reliability and many pipelines result in water escape, emission, dripping and seepage. Regular inspection and maintenance is required. Low reliability results in water escape, emission, dripping and seepage. Regular inspection and maintenance is required.
    Good appearance Only beautiful temperature controller is seen in the house. It doesn’t look good to have so many pipelines, indoor radiators and outdoor exposed chimneys. There are exposed components, pipelines and radiators, etc. A lot of manpower and financial resources are needed to decorate them, and cover pipelines and radiators.
    Comfort Ground radiant heating is balanced and even, without the difference between cold and heat; it is healthy, clean, as warm and comfortable as sunshine. Convection of indoor hot air leads to floating dust, dry air and imbalanced heat dissipation. It is cold below and hot above, which is uncomfortable and bad for health. Convection of indoor hot air leads to floating dust, dry air and imbalanced heat dissipation. It is cold below and hot above, which is uncomfortable and bad for health. There is noise and exhaust gas 24 hours a day.
    Maintenance costs None The price of new furnace is high. Daily maintenance of radiators and pipelines also expends lots of manpower and financial resources, and destroy the environment, roads and landscaping in the community. The price of new furnace is high. Main components shall be maintained or replaced regularly, which damages home furnishings.
    Operation cost Electricity use is encouraged. Price of electricity in valley period is available. So operation cost is low, and heating expense is 10%-30%.
    Fuel gas. The cot of coal combustion, transportation and operation is relatively high.    		  High
    Thermal efficiency Over 99% 60% 0%
    Temperature adjustment Heat any room anytime Temperature control is available It is not easy to adjust the temperature. Therefore, room temperature is inconsistent. Regulation and control is available, but indirect and inconvenient.
    Energy saving The operation is economic and energy-saving. When leaving, you can lower the temperature or shut down the system (which is started via telephone remote control). The system operates in the same way when people are in or out. This is not energy-saving, and not good for household-based heat metering. Natural gas and water resource are in short supply. Their prospective prices rise.
    Water consumption None Hot water is needed for circulation, and lots of hot water runs off, which waste water resource. Water is needed in thermal cycle.
    Area None (Generally speaking, it saves 3-5% of indoor useful area and space) Furnace body, pipelines and radiators occupy certain room. Moreover, there are coal piles, clinker and soot in coal-fired boiler rooms, which also occupy precious ground (about 3% of the community area). It occupies a certain useful space and room in the house.
