Radiant Heat Intro
This new slab floor and our goal of energy efficiency point towards even, warm floor, radiant heat instead of the existing baseboards. Since hydronic radiant heat requires a lower temperature than baseboards, it is capable of incorporating several different heat … Continue reading

Uponor Wirsbo Complete Design Assistance Manual 4th Edition
The very best resource I found for understanding the requirements and design parameters of radiant heating was a book borrowed from my friends who installed their own radiant system a few years ago. It is a large paperback from Uponor … Continue reading

Designing a Kiva Fireplace with a Boiler Stove Insert
I have always admired Kiva fireplaces. They seem both rustic and homey. And this house already has a rough stucco wall in the living room area so a Kiva seemed to be a perfect fit. Our architect, James Plagmann, drew … Continue reading

Insulstar!
Quite a bit of time went into researching the insulation for under the slab. The engineers were concerned about the insulation holding up to the stresses that the wafflemat would be mitigating. Apparently no other customers of Wafflemat had required … Continue reading

Water Loop in Action
The water supply trunk loop is connected and stubbed out. This is the longest above the concrete connection. The pipe near the wall will connect the washing machine and the other connection will run to the guest bathroom. This long … Continue reading

Radiant Installation
Unfortunately the pex roll was unweildly and as the first zone was unrolled, the pex became extremely tangled. The 1000 ft. roll came in a box and did not have a plastic sleeve to hold it in place. Several crimps … Continue reading

Triangle Tube Boiler
We first heard of small, highly efficient, condensing boilers from Melissa when she did our Energy Audit. After some research, I found many recommendations for the Triangle Tube boilers. They have stainless steel heat exchangers, and copper piping. They are … Continue reading

May Snow!
Denver has an interesting climate. Snow tends to fall most often in the spring. This year it snowed on the first of May (and the second had more flurries.) This snow does not tend to stay around long and in … Continue reading

Hot Water at Last!
YES! Endless hot water @ 2.4 gallons per minute. That was enough for a nice long shower, first one in the house in about a year. So nice to finally have the water system connected and hot water running again. … Continue reading

Air Barriers
One of the benefits of blogging is to organize thoughts about next steps. When Sarah visited, she advised me to finish the external barrier first and that was a helpful comment in a sometimes overwhelming project. I am taking apart … Continue reading

Roxul Rock Wool Arrives
After a couple of false starts by Lowes, the rock wool insulation was finally delivered, which meant a full day of hauling it from the pallets on the driveway to the inside. This job fell to our son-in-law and four … Continue reading

More About Rock Wool
Insulation, just like so many LEED building options was a rather tortuous decision. I was introduced to the idea of using rock wool by Sarah, my LEED expert friend. She recommended looking at rock wool for a couple of reasons. … Continue reading
