when our heating system was changed from a back boiler to a wall mounted one we had the back boiler removed so as to revert to a 1st class chimney, so we could have a coal fire if required, and the flue liner was taken out.
Hi, Direct heating is where the heat source i.e and electric element is in the tank heating the water directly. Indirect heating is where the heat source is remove i.e a boiler piped up to a coil in the cylinder of water. Hope that helps, Any further information please get in contact with me.
behind the glove box, some models require pulling the dash, some you can just remove the glovebox.
It's used to remove air and gasses from a boiler system.
You only need to remove the center knob, not the panel.
by heating
the water can be removed heating the anhydrous.
The blow down used to remove sediment from the mud leg
it is located inside the heater control box up in behind the centre of the dashboard,to remove and replace the dash has to be completely removed.
Cycles are a measure of the dissolved solids in the boiler water in relation to the dissolved solids in the feedwater. For instance, if the measure of chlorides in the feedwater sample is 5 ppm and the chlorides in the boiler water sample is 50 ppm then the boiler water has been cycled ten times, 50/5 =10. That means that all of the water in the boiler (plus all the water that has been blown down) has been evaporated completely ten times, and replaced by the same amount of feedwater. Steam does not carry the dissolved solids out of the boiler, they remain behind, these are controlled with water treatment and a continuous blowdown (bottom blowoffs control or remove suspended solids).
desalination process is used to remove salt and the large boiler are used for it

deaerator is a device used to remove dissolved oxygen and carbondi oxide in boiler feed water. it causes scaling inside the boiler tubes and economizer also.
