With the new ‘old’ pickup, I went to one of Matt Jung’s job sites today to pick up some HDPE tubing.

While on job site in Los Altos, I was given a quick tour of the progress and was able to take a look at the various components of the hydronic heating system.

Each heating zone requires a manifold, as shown below.

While the manifolds may be located in the house, the utility room houses the boiler, hot water storage tank, and expansion tanks.

The most real estate is required for the hot water storage tank. Note the earthquake straps holding the tank.
