I would suggest that the refractory has been soaking up moisture for several years so its best to slowly bring it up to temperature to keep any moisture in the refractory from turning into vapor and cracking it.
Nah, they still out there..."oven bulbs"...and you can find larger "specialty bulbs" too...ebay has some.but finding a incandescent light bulb these days would be a major project
I saw how @hobbyheater cured his I will do the same process. Good advice, thanks.I would suggest that the refractory has been soaking up moisture for several years so its best to slowly bring it up to temperature to keep any moisture in the refractory from turning into vapor and cracking it.
About one fire every third day. The Jetstream had a small loading tube and needed to be loaded every hour for a 10 degree rise in storage temperature, 150 to 195 degrees four loadings , 120 to 195 degrees seven loadings .@hobbyheater How many fires do you have on a cold day? Just curious…someone in my town had the same boiler as me and claims it’s inefficient and not worth running. He said on cold days he has to baby it and constantly fill it for 8 hours to get it up to temperature. (My tank is larger than his but so his my house) a average day in Maine in the winter is probabaly 30 degrees rarely colder than 10
It's all good if some of that waste heat is going to good use. In my case I would heat that building by some other method if the boiler was not there. Much nicer to load and service the boiler out of the wind and in 45-50F vs -10F.@3fordasho my 1500 gal in 5 foot by 20 foot enclose full of blown in will steep my garage slightly above freezing most the time, no insulation in garage, thats not happening,but I had no room to put tank in the house, its a BOB, but i really dont mind the heat in the garage it keeps pool pump/filter from freezing and helps make it livable until I fire the used oil burner up if I am doing something out there. it does wast some heat though but what do you do on a limited budget and with given space in an old house?
