it simply heats water as the water passes through the tubes
.
Is a boiler more efficient than a hot water heater?
System – a system boiler doesn't require a cold water tank, but it does have a hot water cylinder. …
Condensing boilers
are sometimes more energy efficient than other types, as they retain the heat that escapes the flues – for venting toxic gases produced when heating water with gas – present in non-condensing boilers.
What size water heater is considered a boiler?

120 gallons (454.2 liters)
nominal water storage capacity; 160 psi (1103.2 kPa) operating pressure; 210 degrees Fahrenheit (99 degrees Celsius) operating temperature; or.
How much does a boiler cost?

$5,754 on average
with a typical range between $3,645 and $8,162. A standard efficiency model (80%-89% AFUE) runs an average of $3,000 to $6,000. High efficiency models (90%+ AFUE) cost $6,000 to $11,000. Of that, labor costs $1,000 to $2,500.
Can a boiler work without water?
If boilers didn't come with a host of sensors and controls, it might indeed
damage your boiler
if you turned it on with no water to heat up. Your combi boiler would be the worst affected, as the heat exchanger could suffer, but your cylinder and radiators would probably be fine.

Is there a big difference between a 40 gallon and 50 gallon water heater?
The Energy Factor
The cycling losses measure how much heat is lost as the water circulates through the system. … With the energy factors being equal, the difference in cost of running a 50-gallon heater over a 40-gallon heater is
essentially insignificant
.
