### Minimum operating Gas Pressure on boiler | Screwfix

Dec 02, 2014 · I filled the water pressure to about 12/13 psi when the boiler was cold. After turning on the heat, the water pressure increased to about 20 psi and stayed there during the 3 hours of heating. The water temperature increased to about 160-180 degrees. 1. Is 20 psi a normal operating pressure for residential boilers?

### What is the safe pressure for a hot-water-heating system?

A natural gas burner rated at 40,000 BTUs per hour divided by 1,000 BTUs per cubic foot uses approximately 40 cubic feet of natural gas in one hour. Exact Gas Consumption Step 1 Multiply the burner efficiency by the energy content of the gas being used. Natural gas contains 1,075 BTUs per cubic foot; propane contains 2570 BTUs per cubic foot. Step 2

### How To Calculate Natural Gas Boiler Consumption--ZBG

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3, pressure 8-10Kpa, and theoretically, the gas consumption of boiler heat = boiler calorific value÷ (Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/h, here we take 4 tons of natural gas boilers for example, then the boiler gas …
