1.1ton gas boiler 6000-8000 square meters, 2ton gas boiler 12000 square meters -16000 square meters,

The heating area of the 3-ton gas-fired boiler is 18,000-24,000 square meters and the heating area of the 4-ton gas-fired boiler is 24,000-32,000 square meters

2. Small value for North China and large value for East China and North China;

3.1-ton gas-fired boiler has a rated gas capacity of 80 m3 / h, a 2-ton gas-fired boiler has a rated gas capacity of 160 m3 / h, a 3-ton gas-fired boiler has a rated gas capacity of 240 m3 / h and a 4-ton gas-fired boiler has a rated gas capacity of 320 m3 / h.

Also need to consider where your boiler installation use?

Gas consumption per unit time = 1 ton (600,000)/boiler efficiency/unit volume heat output

Service area = boiler heat output per unit time/requirements per square meter

Take Beijing one-ton gas-fired boiler as an example (natural gas calorific value =8600Kcal/h, boiler thermal efficiency 85%, heating 100Kcal per square meter per hour)

Gas consumption per unit time =600000/0.85/8600=82 cubic meters

Use area =600000/100=6000 square meters
