I turned off valve on 1 of 2 radiators in bedroom cuz too hot. Any risk to system? Anything else I should do?

Question

House from 1890; closed hot water radiator system. Oil driven furnace. My upstairs bedroom is too hot cuz when I renovated the room, I put insulation in the room so it stays warmer than the other rooms in the house and is also upstairs where heat rises. I turned 1 of 2 radiators off in the room by turning valve to off. I want to know if there is any risk to the rest of the closed system such as too much pressure on the return or that other radiators may not get water from system though I think that the radiator I shut off is at the end of the line...thx in advance, Rob

Answer 1

There should be no problems unless you only have a 1 pipe system which could shut something off downstream. There definitely won't be any issues with the rest of the system or how it operates. If you find that another radiator is not getting heat just crack the valve open a little bit to create some flow to the next unit. You probably are at the end of the line there so it shouldn't affect anything else. If and when you do turn it on it may need to be bled because air might catch or build up in it.

Good Luck!

Answer 2

check the heating pipe loop in the basement, and see if you have flow valves for the pipes that go up to each room. you shouldn't have any problems if you do. worst case scenario would be that the 2nd radiator in that room is in line with the 1st radiator and you'd have shut down the loop to that bedroom. if each radiator has it's own rise pipe, you'll have no problems. good luck, hope this helps.

Answer 3

If you have a single pipe system and there's no pipe going around that radiator you've just shut down your system. Check it out, make sure you have a pipe going around that radiator. You may have to have a separate zone valve put in with another thermostat.
