Steam Pipe Removal

January 27, 2014 / / 2 Comments

I’m sorry folks. This post could have been full of exciting, spark-showering photos of angle grinding, but we didn’t take in-progress shots. In fact, I only took phone camera pictures, so on top of not being as interesting they’re also grainy and blurry. I’ll try to do better.

Anyway, here’s the old boiler and steam pipes in the foreground with the new boiler and new panel in the background. I finished taking down the steam pipes this weekend. I mostly used the angle grinder with a cutting disk, though in a few places I used the reciprocating saw with a metal blade and some cutting oil.

I was surprised to find that one section of the return pipes was still full of water, even though it hadn’t been running since last winter. I thought it would have evaporated by now, but I guess not. It eventually drained and I finished cutting it out.

Because some of the supports were literally falling out of the ceiling, I strung it up in places with wire and bungie cords while I was removing it. All of the pipe went into my scrap pile, which at this point takes up a decent chunk of the basement. Once the snow melts I’ll haul it over to the recycling yard.

Once everything was taken down it really opened up the basement. I also removed a leftover section of the old gas pipe while I was at it, just so I could call it 100% done. With the pipes removed and the chimney down, there’s nothing in the way of finishing the new subfloor, except for all of the stuff on the first floor I have to move out of the way. I’ve got most of the back section done, and I’m hoping the rest of it will go more quickly.

The old boiler will wind up going to scrap too. It’s not as heavy as I expected. It’s pretty amazing how much different this section of the basement is from when we bought the place. I suppose that’s true of the first floor, too, since it’s all gutted, but somehow this feels more substantive.

Frozen Over

We got heat in the nick of time, since it got really cold in early January in much of the country. In Chicago, the low of -16° on January 6th beat records. The second floor stayed nice and cozy, thanks to our new boiler and radiators as well as the attic insulation. The rest of the house didn’t fair as well, and we had frozen pipes in the basement, a frozen washing machine, and frozen condensate line and intake on our hot water heater. Fortunately our hot water heater is fancy enough to detect the problem and shut down, as well as display the problem on the screen, making that part easy enough to fix.

The frozen pipes, on the other hand, required a bit more work. I never put pipe insulation on because we haven’t had our rough plumbing inspection yet, since I’m waiting until we complete rough plumbing on the first floor. That decision proved short sighted. We had relocated our electric heaters to the first floor and basement in an attempt to keep things above freezing, but it’s so drafty there wasn’t much hope. We wound up thawing things out with a heat gun to get the water flowing, and fortunately didn’t have any pipes burst. I don’t know if that’s because the water filter is able to absorb the increase in pressure or just dumb luck. In any case I added not only pipe insulation but pipe heating cable, which wraps around the pipes and uses about 60 watts, compared to the ineffective electric radiators that use about 1,500 watts each. It has a built in thermostat to kick on only when the temperature is below 38°.

However, before we were able to get the insulation installed everywhere, and because they were sold out of the longer lengths of heating cable, not everything was wrapped, so we wound up having a second pipe freeze despite our efforts. The washing machine was another casualty. Since we neglected to turn off the water and drain the hoses, the water inlet valve froze and split apart. When we got back from our vacation I took the thing apart, found the problem, and we bought a new one and and got it installed. We’ve been catching up on laundry the last couple of days and disconnecting the hoses at night when the forecast calls for sub-zero temperatures. We also put a thermometer in the basement to keep track of the how cold it is down there. The good news is it’s staying above freezing in the basement when it’s 5° outside. I’ll try and determine what the danger point is, though there’s obviously a time factor in addition to outside temperature.

Meanwhile we haven’t made much progress on other projects. Between the freezing, a nice vacation to Cancun, and being sick after we got back, January hasn’t been nearly as productive as I had hoped. Instead of working on subfloor I’ve been taking out the old steam pipes, since I need to get them out before I can finish the subfloor anyway. I may do a post about it, but I haven’t taken any pictures yet.

Heat!

Oh, finally, finally we have real heat! Up to this point we’ve been relying on a collection of electric heaters meant to supplement rather than stand in and even running four of them and consuming 6,000 watts of electricity in the process, it’s been cold. The insulation helped quite a bit, but ultimately we just needed the radiators working.

Lester finished up the other jobs he’d been working on and started working more seriously on our project. Over the course of a couple weeks he got the mechanical panel built out and the boiler hooked up. We figured out where we were temporarily putting the radiators on the second floor (until we remodel the floor and install in-floor radiant) and Mike helped me mount plywood panels to the wall so we could mount them. We also got the old steam radiators out onto the back porch.

I had originally wanted to run the PEX tubing that supplies the radiators through the attic, so Lester was going to put a manifold on the second floor. I decided the manifold could go behind the dishwasher since it’s on the wet wall and that spot will be in the master bath once we remodel. Unfortunately, when I pulled out the dishwasher and cut open the wall I found that spot occupied by five different supply and drain pipes.

Instead Lester put the manifold on the first floor and ran the PEX through the first floor. That may complicate things later, such as the plumbing that needs to go right where the manifold is and the ceiling where the tubing is running, but I guess we’ll figure that out when we get there. Top priority was getting heat.

Radiator being warm

With the radiators mounted and everything connected, Lester fired up the system and soon it started to get warm. We’ll still use one or two electric heaters if it gets too cold outside since the radiators are sized for our future insulation rather than the current lack thereof, but the difference in warmth and comfort is profound.

We had one hiccup though. After we got back from a long weekend with my family we discovered that the pipes had frozen. I had put an electric heater on the first floor but the circuit tripped so it wasn’t running. Fortunately there was no damage and we got everything thawed back out. This weekend I’m planning to get some pipe heating cable since its much cheaper to run than a 1,500 watt oil-filled electric heater.
