Water-tube or fire-tube condensing boiler, which is the

In a water-tube boiler, it contains a minimal amount of water at any given time. It may be just one-tenth the volume of a fire tube boiler, which requires a larger volume of water to act as a heat shield so that metal in the boiler doesn't melt and create problems. When fire tube boilers run low on water, the metal in the boilers shrinks.

Which Industrial Boiler Is The Most Energy Efficient

This design requires only 10% of the water that's typically found in conventional fire tube boilers and helps give the LX model 85 percent fuel-to-steam efficiency. Most fire tube boilers will max out at 83 percent fuel-to-steam efficiency. However, this small difference can amount to anywhere between 10 and 40 percent savings in fuel costs.
