The average lifespan of a boiler tube is 20 to 40 years. Boiler tubes are made out of heat-resistant carbon and low-alloy steel.
The words are literal , a water tube boiler is water inside the tubes with hot gases surrounding them and a fire tube boiler are got gases within the tubes with water surrounding them.
the advantage is the design is complicated

Combi boiler are installed often by the British Gas company and the average price they charge to install the boiler into a customers home is an average of about 2900 Euros.

the advantage is the design is complicated
there are two types of boilers water tube and fire tube. fire tube boilers are divided in to two categories vertical and horizontal. this according to the construction of fire tubes. it is said that vertical boilers are inefficient than horizontal boilers. The vertical boiler is small capacity, and horizontal boiler is higher capacity, well, the horizontal boiler have many types according the drums, there are single drums boiler, and double drums boiler, while, the single drums boiler have fire tube boiler and water and fire tube boiler, double drums boiler is usually water tube boiler.
Fire tube and water tube. Steam Boiler and Water Boiler.
A simple vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation.
The answer is in the name. Boilers are made with a "tube - in - shell" construction, and the name implies what is in the tube. In a water tube boiler, the water circulates through the tubes, and the burner is usually under them. Most of the time, the "shell" of this style of boiler would not be watertight. A fire tube boiler has a watertight outer jacket with tubes through the center of it. The flame is shot through the tubes.
The difference between the two is that the Water tube boilers are safer and last much longer than the fire tube boiler. Their size is also larger and have a faster recovery time. However fire tube boilers have a low cost.
water
In a fire tube boiler, the water surrounds a set of tubes through which the fire and the products of combustion travel (as opposed to a water tube boiler, in which the water travels through the tubes, and the fire surrounds the tubes).The HVAC Veteran

Usually Alloy steel is used, copper and brass are also used as boiler tube materials
