Open the pop off valve on the top and see if air releases.
If this does not work may need to replace water heater. This is very dangerous and can explode if the pressure builds to high!!!
How do you know it's vapor locked?
There has to be water in either system for it to work, check with the manufacturer and provided documentation to discern proper water capacity.A hot water boiler (hydronics) as opposed to steam is a system that is filled with water and has an automatic feeder to make sure the boiler never dry firesA steam (vapor) system has a limited amount of water so it has space to make steam and can have a manual feeder BUT like a hydronic system much have a low water cut off to prevent dry firing
A boiler works by heating water in an enclosed space. The expansion of water molecules as it transforms from a liquid state into a gaseous one causes the boiler to generate a vast amount of pressure. This is generally the science behind a back boiler.
This unit does require water,you can add vapor to the water if you wish.
A combination boiler does two tasks, the first is to provide radiant heating to a building and the second is to provide hot water. The boiler can provide hot water to only one system at a time, but eliminates the need to have two boilers.
Pasta needs to cook in rapidly boiling water, so a double boiler won't work that well for cooking pasta.
For a while IF the boiler has an automatic low water cut off and other safety devices but if any fail you will have a melt down and an explosion
dewpoint apparatus
Liquid water becomes water vapor through a process called evaporation, where heat energy from the surroundings causes water molecules at the surface of the liquid to gain enough energy to break free from the liquid phase and enter the gas phase as water vapor.
It cools down the water vapor. It gets converted into water droplets.
A broiler is a mechanism that boils water that produces steam. The steam can be used for a purpose such as cooking foods.
Yes, If it is a pressurized system, the water from the back boiler and your oil or gas fired boiler can be mixed. This can also be achieved by using a water to water plate exchanger to preheat the return water from your heating devices. If you have a forced air heating system in the house, a coil can be placed in the main trunk line of the duct work and heated by circulated water from the back boiler.
A water pot boiler works by heating water in a closed container using a heat source such as a stove or electric element. The heat causes the water to boil and turn into steam, which then rises and transfers heat to the surrounding water. This process efficiently heats the water in the pot.
