Windhager install

[heaterman]

This customer had a Horstmann wood boiler in his basement and is to the point in his life where he does not want to deal with the "wood thing" as he put it. A pellet boiler is a good fit for him and will be for many years due to automatic fill and automatic cleaning. He's thinking about adding a bulk storage bin at some point in the future but for now he's going to just use the integral hopper and fill a a couple times per week.

There were some "issues" with the system piping which Drew and Matt corrected when they did the install. About all that remained of the original zone piping after they were done was the supply and return manifolds. Everything else went away. As an example, one of the mistakes in the original piping was the use of gravity type checks on each zone that were installed vertically. They all fell open and stayed that way. So when one zone ran, they all "ran".

We had to design for the inclusion of the LP backup boiler he had someone install a couple years ago and we rigged it up to simply monitor the primary loop temperature and fire when it drops below the target temp. We set it at about 115* as the entire house is radiant slab.

Sweet!

You may want to get the local TV news crew out there to do a story. Free TV promotional brainwashing.

Once all the oil burners turn on their TV sets and see the smiling face of the pellet burner owner on their flat screen, as soon as they realize they're not keeping up with the Jones's, they're going the way of the dinosaur, then the OA temp drops and they start to shiver, your phone will ring non stop.

The Windhager, LP gas boiler and all the heating zones are piped into a common primary loop. The actual supply and return manifolds for all the radiant floors were piped through a manual mixing valve that was only 1/2". Whoever installed the original piping used brazing rod to do all the tee's. Never saw that done before.

Here's a better look at the primary loop.

Nice! Did the customer free up a flue in the basement by installing a modern LP boiler with venting out the wall?

He actually never had a gas boiler at all until a couple years ago. The only thing he had was the Horstmann wood boiler. His wife finally prevailed on him to get some kind of a backup in case something happened to him.

We connected to the flue vacated by the Horstmann and it's a bit oversized for the Windhager. We'll be keeping tabs on the draft situation as he gets into the heating season and drop a liner down his chimney if we can't keep it under control.
