How much water !!
« on: June 23, 2019, 04:54:27 pm »

Was wondering if there is a rule of thumb in how much water to fill a boiler for optimum output ?

I was told to never fill it the top of the sight glass.
Right or wrong I do not know but it seems to work for me.

Hi, No sight glass.  :}   I tend to fill about 2 thirds but just wondered if that was correct or not.

All depends on where the water gauge sits. You certainly dont want to over fill a boiler as you will get hot water instead of steam. My advice is that you must have the flue covered assuming its a horizontal boiler, then as little water as possible to satisfy your time in steam. This is the mose efficient way of steaming and means that you are not heating water which will not be used. For a vertical boiler my rule of thumb is to have 1/3 water left at the end. This ensures the boiler and flue dont overheat.

Make sure that you run out of fuel before water!

Hasn’t that boiler got a “dribble plug” on the engine end. Take it out, fill boiler until water comes out then replace it.
