Help identifying what I've got
I recently moved to an old farm house that was recently gutted and redone. The work looks top notch. The question is can you help me identify how the HVAC system is designed to work. Asking the installer is not an option unfortunately. Here's what I know:
1) it's a munchkin 140m boiler running four zones: upstairs, down stairs, back room, and domestic hot water. Upstairs is 5 rooms worth of fin type baseboard. Down stairs is three rooms of baseboard with one kick board heater under the kitchen sink. The back room is one kick board heater under the back sink. ( back room is 14x17)
2) I don't think there is an outdoor thermostat associated with the boiler
3) I am burning propane.
The specifics of my question are:
1) I don't see any type of mixing valve where the inlet and outlet meet. There is just a pipe that connects the two sides of the loops. Should there be a valve?
2)The kick board heaters have an electric blower that use a ton of electricity. Keeping the back room warm 55F (insulation is bad,it's the only room that didn't get a full makeover) doubled the electric bill for one month. We just shut the room off for the winter. Would you expect the jump in electricity to be that sever. Usage went from 437kwh to 980kwh.
3) The kick board heater in the main kitchen is first in the loop. From the main loop outlet, a line tees of to the kick board via a smaller white pipe, not pex like everything else,, then the kick board's return tees back in to the main loop a couple of feet down stream from where it originally teed off. Is is ok to do it like that?
4) The last base board heater in the first floor loop is the downstairs bathroom. It is always freezing. It is furthest from the.thermostat on the north side of the house. The rest of the main floor is comfortable so I don't want to heat up everything else more just to heat the bathroom. Do I have any options?
5) None of the exposed pex lines have pipe insulation. Should put some on?
Thanks for any help.
