Generally speaking, the rated thermal efficiency of 1 ton boiler is 0.7MW (700KW), 0.7mw heating area is regional differences, heating 50~70W/㎡, 1 ton hot water boiler heating area is generally 6000~10000 ㎡. Now some areas also stipulate heating 32W /㎡, 32W can be nearly 15,000㎡, the specific design should leave a margin.

Conversion formula: 600,000 kcal/h ≈1ton/h≈0.7MW

Advantages of  hot water boilers: This type of boiler achieves the advantages of full combustion, no pollution, convenient operation, and convenient installation; this type of boiler has high thermal efficiency, large output, strong load adaptability, high degree of automation, convenient operation, safe and reliable operation, and is high-efficiency, low-consumption, low-pollution green products.
