Introduction Coil Type Boilers have become the number one choice for steam generation and their popularity is set to continue; and no wonder when you look at their many advantages. Not only are they more energy efficient, easier and safer to operate but they are very quick in raising steam, from three minutes from a cold start to full output.
The main disadvantage of cold lay-up is that natural circulation cannot be achieved. It is recommended that a small, low pressure circulating pump be installed to provide the needed circulation. This pump must be isolated prior to start-up as it will most likely not be designed for
Traditional fire tube boilers use up an awful lot of fuel and money. They take so long to get started that they often have to run idle when not in use, which is wasteful and costly. This isn't an issue with smaller, modular boilers, as they can start producing steam within minutes, even from a cold startup.

The Europeans who came up with this figured the same coil, but with a boiler that holds three gallons of water, that's a 6 to 1 turnover as opposed to the 28 to 1 that many try to do.With wall-hung, modulating- condensing (mod-con) gas boilers that hold a couple of quarts of water, cold-start will generally work, but they don't make them
Preheating makeup water is a critical step to maximizing the efficiency of many boiler designs. In the case of a conventional fire tube boiler, a steam sparger is often engineered into the condensate return tank to maximize efficiency by making sure that the boiler does not have to work harder to transform cold water into steam.
