Use cainuanlu licensing and dual-use furnace heating hot water how to choose?

Independent heating time, for no universal central heating, generally can choose to install wall hanging furnace as independent heating of the heat source, tie-in heating radiator and floor heating system.
When choosing wall hanging furnace according to different purposes, wall hanging furnace is divided into cainuanlu alone and combined furnace heating hot water. Amphibious furnace is relatively more convenient, need not connect other devices, in addition to providing circulating hot water as heat source heating system, but also directly provide hot water bath, shower and so on life.
Compared with traditional heating hot water dual-use furnace gas water heater, what are the advantages?
Relative to the gas water heater, wall-mounted gas furnace power more generally speaking, hanging furnace hot water output more abundant; Closed combustion gas wall hanging furnace, thermal efficiency is higher, common water heater burning gas thermal efficiency reached 84%, and wall-mounted gas furnace thermal efficiency is low of 88%, and the cooling wall hanging furnace thermal efficiency of more than 100%, wall-mounted gas furnace more energy-saving than gas water heater; Wall-mounted gas furnace in to have a more comprehensive security protection measures, including antifreeze protection, prevent dry heating protection, temperature protection, accident flame-out protection and other protective measures, to use it safely.
Cb, however, to provide living hot water is one of the function, its main function, or heating products relative to the single function of gas water heater will be a lot more sophisticated internal accessories, cost is also relatively increase.
Cb wholesale from the product specifications and technical content is divided into different conventional furnace and condensing furnace, popular, cb condensation can be seen as a routine in cb updated version.
Exhaust smoke temperature is different. Conventional wall hanging furnace exhaust smoke temperature is in commonly 160 ~ 250 ℃, is even higher, makes the gas produced by the combustion of water is in a state of overheating steam in the flue gas, and with the loss of smoke from the chimney, so regular wall hanging furnace thermal efficiency generally can only reach 85% ~ 91%.
Condensation in cb, unlike conventional furnace, cooling wall hanging furnace can reduce the exhaust temperature to 50 ~ 70 ℃, full recovery of the sensible heat and water vapor in the flue gas condensation latent heat, high thermal efficiency can reach more than 100%, the energy saving effect is outstanding, the late operation cost is low.
Processing scale is different. In order to improve thermal efficiency in ordinary wall hanging furnace, often USES the small size of the heat exchanger, water pipe not only small, and the thickness of the pipes is compressed to the lower limit. But in some parts of water quality of high hardness, easy accumulation scale after heated pipeline system, damage to equipment.
Condensing furnace with a new mixed combustion heat, using big water pipeline system. Therefore, compared with the traditional wall hanging furnace, don't worry about scale problems.
Life is different. Common cb key parts such as investment promotion to join due to the combustion chamber, heat exchanger is a design problem, combined with domestic water quality, gas quality and other factors, lead to the service life of the product to meet the general design requirements for 15 years.
