So I’m looking to see if there is a way to install a two stage gas valve on a steam boiler that would limit the heat output of steam boiler when only the water zones are calling and when the steam boiler turn on it can go to high stage.
2017/01/11 · Based on the radiation analysis on your other thread, dumping 129,000 BTU/hr of boiler output into a zone with only 164' EDR of radiation means that the boiler would be firing at less than a 25% duty cycle when serving that zone, and about a 30% duty cycle when serving the zone with 226'. ...
In coil type boiler, water flows inside the coil tube and flue gases are on the shell side so they are also known as water tube boilers. Here the water tube coils are in direct contact with radiation as well as convection heat zones and are therefore the most efficient boilers.

The type of fuel you burn has no bearing on this.
I have used a tankless coil in a steam boiler numerous times to produce multiple zones of forced hot water heat. Make sure to use a high limit in the forced hot water zone, usually set for 180 F, to prevent the boiler from making steam when steam is not wanted.
Hot water systems are closed, meaning that the water constantly circulates through the pipes and into the boiler. Newer units have many zones with two water pipes linked to each zone: one circulating heated water to the rooms and the other returning the much cooler water back to the boiler to get reheated.
