Adding the radiant loop

To continue with the plumbing work I needed to connect all the piping from the pex tubing, through another pump and into the heat exchanger.

OK, now we are rockin'. The loop for the pex tubing is installed. The thing with the tag on it is a mixing valve that mixes the cooler water returning from the loop with the hot water coming out of the heat exchanger and that water goes up tat diagonal pipe to heat the pex loop.

Here is the same angle but from a little farther away.

And another from a different angle. Maybe this stuff is boring to some people but how cool are all those pipes!

Plumbing - Tieing into the boiler

Now this is cool stuff! To get hot water into the pex tubing first you have to get hot water from the boiler and force it through a heat exchanger. This heats up the heat exchanger and then there be another loop that feeds through the heat exchanger. First things first: Tapping into the boiler water is the tough part. While I'm working on that we won't have any heat or hot water....so I'll start after the kids go to bed and ... we'll see how long it takes me.

Here you can see the tee in the bottom left hand side of the picture. The red pump in the middle will pump water from left to right. The water will be pumped out of the boiler (on the right), through the tee, and up and through the red pump.

Here you can see the same red pump from a different angle. The water is pumped toward the camera and then into the heat exchanger on the right. It comes out the bottom and then back through the tee on the bottom left and back into the boiler. You can see the two ports on the heat exchanger that will be connected to the pex loop... that's next. Oh, and I finished at 1:30am
