Posted on January 31, 2016 by ellen

As part of the pump install I changed the wiring again. In the past I had trouble with the primary and secondary pumps working independently. I thought that was one of the things that wore out the Taco 011 pump … Continue reading →

Heat is Back On

Posted on January 31, 2016 by ellen

I left the heat off until the days stopped being sunny. During that time the house temperature didn’t go below 64 degrees. Even when it got down to 20 degrees outside at night. We woke up to a steady 64 … Continue reading →

Ach Phooey! Taco Pump Siezed

Posted on January 24, 2016 by ellen

Since we returned from a trip to see our newest grandson about a week ago, I’d been noticing that the floor was not warm but the radiators in the back were. I thought since I had turned the heat down … Continue reading →

Cleaning the Challenger’s Heat Exchanger

Posted on December 10, 2015 by ellen

When I was wiring the boiler, I checked the condensate overflow system on the boiler and noticed the plastic drain was full of black gunk. I cleaned it out and about a week later checked it again and it was … Continue reading →

Boiler Wiring Fix

Posted on November 19, 2015 by ellen

This summer I re-built the zone valves for the boiler. And I planned new logic for the wiring so that I could include the fireplace boiler and hopefully a chiller. I had the new single pump relay using the output … Continue reading →

Current Wiring for the Boiler

Posted on December 15, 2014 by ellen

Way back last spring when I was finishing up the boiler wiring, I had problems with the secondary pump such that I replaced the used pump I bought on ebay with a brand new Taco 011. That was expensive but … Continue reading →

Pump Problems

Posted on March 24, 2014 by ellen

Taco seems to be a well-respected name in water pumps. The 00 series is especially popular. These range from an 003 to an 013. Triangle Tube instructions recommend both the Grundfos and the Taco pumps. For a system the size … Continue reading →

Chronicle of Errors

Posted on March 23, 2014 by ellen

I mentioned there were several things wrong with the first installation of boiler piping. When tested, water was not getting through the system and I believed the pump was just not strong enough to circulate through all the radiant loops. … Continue reading →

Primary/Secondary Piping Complexities

Posted on March 16, 2014 by ellen

This is the new primary/secondary piping. It follows several boiler piping rules of thumb, although the 009 pump is now a bit over-sized for the primary loop. There is a secondary 011 pump that also is capable of pumping at … Continue reading →

From Simple to Complex

Posted on March 16, 2014 by ellen

The original boiler piping design was going to be a single loop system. Return water would be pumped through the system to the boiler and hot would flow out to replace it. One Taco 009 pump was chosen for the … Continue reading →

Double Double Toil and Trouble

Posted on March 9, 2014 by ellen

This old brown pump came with the house (also an 006) but did not pump. I replaced this one with a different Taco 006 that includes a temperature sensor. The new pump worked, however, it broke the flow control switch … Continue reading →

Hot Water at Last!

Posted on October 7, 2013 by ellen

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 →

More Boiler Business

Posted on September 27, 2013 by ellen

Even though I thought I did all the research necessary to make a good decision, I have spent time doubting the choice I made for the boiler. The radiant system was sized using the Manual J calculations for the existing … Continue reading →

Boiler Struggles

Posted on May 17, 2013 by ellen

Planning for the boiler install has taken quite a bit of study. Similar to installing the radiant system itself that required learning about pex, radiant pipe layouts, Manual J, heat loss calculations, flow rates, btu’s per square foot, etc. etc. … Continue reading →

Boiler Flue

Posted on May 16, 2013 by ellen

The boiler flue and air supply need only plastic pipe to connect to the outside. Most new furnaces use PVC now instead of metal flue. I didn’t want to put another hole in the roof so I ordered a concentric … Continue reading →

Triangle Tube Boiler

Posted on April 21, 2013 by ellen

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 →
