Radiant Heating System 4

The tubing from the manifolds on the previous page connect to the control panel below (when this picture was taken, only the 4-loop manifold was connected). The control panel, fabricated by NRT Radiant, is a work of art! I wasn't sure whether to put it in the living room or the mechanical room! The yellow romex was a temporary power connection so I could make sure everything was working before the boiler installers arrived.

Here is the control panel after the boiler was installed. The installers from Aiello Home Services did a great job. They actually went through the trouble of running the power through the back of the control board to make it look nice.

This little white box on the north side of the house is the outdoor sensor. The Tekmar controller on the control panel uses the outdoor temperature information to run more efficiently.

And here are some pictures of the Buderus G115/21 boiler and ST120 indirect water heater. This is oil fired since natural gas is not available in this neighborhood and I didn't want to deal with propane tanks. I was skeptical that the ST120 would provide enough hot water, especially since it's only 30 gallons and our electric hot water heater was 55 gallons, but so far it has been working great! We have never run out of hot water.
