What’s up I just moved into a new apartment about 2 days ago and we have an old natural gas heater... Siegler model # 775 UB -2-S.... when we first moved in the property owner told me that the heater worked but was very loud and that he was going to have it fixed ASAP; I’m a certified General Motors technician and I like to consider myself pretty handy so I figured I’d look into it myself; the heater would work fine and blow hot air but was very very noisey and would shake pretty bad; the first thing I did was removed the back panel including the blower motor and fan assembly and found that there was probably thirty five years worth of dust and crap built up everywhere including on the fan; I took apart the fan and motor assembly and I cleaned everything to the point that I was satisfied and put it back together; when reassembled the shaking stopped so I’m assuming that there was so much buildup on the fan that it was just very unbalanced but I still had a bad rattle noise; I removed the front grill and glass panels and replaced the rope gasket and installed new hardware to make sure that the glass was tight and also cleaned out the front and anything that I could reach; when I put it back together it worked perfectly and was quiet and smooth as probably the day it was manufactured; however when it is on for a while I get an intermittent rattle from somewhere in the front of the unit; I have verified that it is not the glass or anything on that front grill; I’ve been trying to find a manual for this thing and can’t anywhere; any help would be greatly appreciated

Hi all, Maybe not the right forum for this question but I am trying to cast a wide net in getting feedback about adding a new heating and cooling system to our 1867 farmhouse in southwestern Connecticut. Currently, we have an oil fired boiler that feeds hot water to big cast iron radiators. The furnace is rated for 286BTU for a 2800sq ft house. Windows updated in 1930s I would say, single pane but no drafts, well built. This all got started when we were looking at adding central AC with a contractor we have used in the past on a previous house whom we trust. He suggested if we are adding ducting for the central AC we should consider a gas-fired high-efficiency mod-com boiler to send hot water to coils in the air handlers to also provide heat and move away from the inefficient oversized boiler. Plus we would be moving to gas which we are happy about. If you talk to most plumbers I find they cringe at getting rid of cast iron radiators (CIR), but our house isn't perfect, we have cold rooms because radiators just don't get the hot water to heat up due to being the end of the line and smaller copper line feeds. We feel the new system would allow us some flexibility in modifying our kitchen which needs an overhaul in the next 5 years and is small with a large cast-iron radiator taking up valuable space, the same is true with a bathroom on the second floor. So thoughts, anyone else heard of using a coil in the air handler to provide heat?
