Let's not forget that there is a tremendous difference in water volume between a firetube boiler and a watertube boiler. From a cold start, the firetube boiler, due to its larger water volume, takes longer to bring up to operating temperature or pressure vs. a similar sized watertube boiler.
The water for a hot water boiler does not need to be potable, but it can still be used as part of a home's radiant heating system and run through the pipes located in a home's walls. A boiler will also have an exhaust, much like a hot water heater, that serves as an escape route for fumes created by the gas burner in the boiler.
How A Water Tube Boiler Works. A water tube boiler runs off of water tubes that are heated externally by fire. The tubes connect to a steam drum and a mud drum, and steam is produced in the upper drum. The water in the tubes creates steam directly, instead of tubes heating water as is the case in a fire tube boiler.
This type of boiler can deliver temperatures of 180-200° Fahrenheit. For those functions that need even more heat, a high-temperature hot water boiler, which provides temperatures of up to 240° Fahrenheit, is an option. You can expect an operating pressure of between 30 to 125 psig from a high-temperature hot water boiler.
The basic difference is that the coiled tube boiler heats the fluid in a serial manner, and the water tube boiler heats in a parallel manner. Because of the difference the water tube boiler is more economical of space and can be used where large volumes of fluid are to be heated.
For more on Boiler Selection Firetube. Non-condensing firetube boilers are available for low- or high-pressure steam, or for hot water applications. Typically used for applications ranging from 15 to 2,200 horsepower, a firetube boiler uses a cylindrical vessel, with the flame in the furnace and the combustion gases inside the tubes.
• If loss of water flow occurs from pumps and the tubes go dry they will overheat quickly and may rupture causing a release of high pressure steam that could damage the boiler. Most boilers have oxygen monitors in the firebox and also in other areas of the boiler.

We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt.
The most advanced water tube boilers require just a few minutes to reach full steaming capacity, compared to the hours it could take a fire tube boiler to reach the same capacity. SIZE There's a considerable difference in size between the two types of boilers.
One difference is the language used to size their output. and the interconnecting water tubes. The watertube boiler design has a heat transfer ratio that typically falls between 0.07 square feet fuel train piping, controls, boiler trim, and a full factory fire test to capacity on the fuels that will be used in the field. In addition
A fire tube boiler creates heat in pipes to heat the water surrounding the tubes, and the boiler vessel itself contains the water being heated. While this type of commercial boiler would be ideal for both low- and high-pressure steam, or for hot water applications, it is limited in the amount of pressure available.
The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy and produce steam. Here are a few key differences between the two:
