I'm in a house that has steam heat (or it at least has a boiler and some kind of water-based heating) and the very small profile baseboard radiators along the walls. The thermostats are both set to 80 degrees Farenheit and the temperature of the house is about 58 degrees upstairs (main level) and 65 downstairs (basement). I have a space heater running near the basement thermostat.
I examined the boiler but to me it isn't obvious there's any problem. It periodically makes some noise like it's doing something, and some of the pipes coming out of it are hot enough to burn me. Two of them - which have metal devices with wires coming out - are perfectly cool and safe to touch. The gauge on the top of the boiler says 225F and ~24PSI.
A big tag on the boiler says CAC / BDP - Indianapolis, IN at the top and Series PWB-4D, model BW2AAN000105ABAA. Says "low pressure boilers" in the certification area. Attached is a circulator pump with the brand Taco, model 007-F5, HP 1/25, Amp .71, 60Hz, 115v, RPM 3250. The pump is hot to the touch but doesn't burn me. There's a tank attached to the pipes that burn me that has the brand AMTROL and Extrol on it and says it is for expansion in a hydronic system.
The smaller electrical boxes which must be zone valves are Honeywell model v8043f1036. I do not know whether they're working or not.
How can I safely "reboot" this so that the baseboard radiators will start radiating? The heat worked last winter. Is it possible there's some circuit breaker or something that has to be switched on when the seasons change? The house also has the sort of AC where there's an external fan unit and a cold air blower in a few of the rooms.
