Finally got it installed! This is the DC32GS with custom made 720 gallon tank & 500 liter Amtrol. This is a great running boiler & will burn whatever you throw in it. The only issues I've had are that I incorrectly set the Samson control & this needs to be accuratly & I'm getting some white smoke out of the chimney at times. The flue gas runs from 350 to 450 in the center of the pipe with a very accurate thermometer. This is a powerfull boiler & heats the uninsulated tank in a cold basementalong with the house very well. I do need to insulate the tank as there is more heat loss than I expected. I should have put in a anti gravity feed valve like my gas boiler has. The system has a strong thermosiphen & that is with the main feed ball valve half closed & one rad valve half closed. With a 1" solenoid valve on this pipe there would be no need for a circulating pump. This boiler is quiet, almost dissapointingly so, I expected more of a rumbling noise. The induced draft fan is all thats heard. The tank charges perfectly, the Lado works flawlessly. I need to do a bunch of insulating & get the Taco anti gravity valve in. This is light years ahead of my old Energy Mate, Randy, I've got 5 more pictures, not sure how to load them though as I'll go over the 700kb.
