Help w/ Regulating Overheating in basement of Commercial building

Chris_51

I'm renting shop space in a commercial building. It gets way too hot in the winter. They don't have a good system for finding the sweet spot. The maintenance guys turn it up and down manually. They need to go pretty hot to get floor to the third and fourth floors.

I'm more of a hot water guy based on my old house. Everything had a valve. But this setup seems tricky.

I took the pictured from the source to the return. The 8 pipes are a huge radiator.

In the next shop on the other side of the first picture, the pipes do a 90, the have a big source manifold type thing. There is a single valve on that. I tried adjusting that last winter to have enough heat, but not super hot. It is almost impossible. The pipes heat before the bend if it's turned down. Or they overheat. When I say overheat the room goes to 80 in the winter.

My thought was to shut off 6 of the 8 pipes. That would cut the heat way down. I guess by adding valves.

I'm concerned that at the end of my 8 pipes, the maniford feeds the next guys room. The last picture shows how he has a 4 pipe radiator going to his room.

Does this plan make sense?

Hi, How about insulating some of the pipes? 🤔

If those pipe radiators overhead are to heat your space, you could cover them with a piece of plywood. or similar item. By covering them you would stop or reduce the convected air thus reducing the temperature in your space. Cover only what you have to to control the temperature. This would be a cheap fix.

That looks like a Vapor system, which is designed to run on very low pressures- less than a pound. Air is vented at a central point in the basement, usually near the boiler. If the air venting is slow, the steam will not distribute well, and it will be hard to heat the upper floors.

Where are you located? We might know someone who can help. The owners would benefit too since fixing this should reduce fuel consumption.

I didn't get notifications on this one. I thought it was strange that nobody responded. Lol.

The pipes go the length of the space, so 30 feet or so. That was one thought. It would not be cheap. The pipes are thick too, so the easy wrap at home depot is way to small.

That is a good idea. If it stays under 80, I guess that is ok. I'd rather have it 65-70.

So when we close the valve in the other room, I can keep it cooler. But when we get the artic blast, it needs to be opened. If I'm in Florida, I need to rely on someone else, which is tough. I do have a wi-fi temp monitor I set up for this year.

Chicagoland. Bridgeport to be exact. They waste so much energy. It makes me sick. I'm just a tenant though. I can suggest.

Would closing 2/3 of the pipes work?
