Thanks, SlimJim,

Tested everything and after getting the air out of the closed loop system, everything is working great.  Hot air is flowing out of the vents, DHW etc.... much better than the marginal warm air that comes from a heat pump. 

I do have one issue thought, in my shop which is open loop I sized the pump to small.  I am using a Taco 007 SS, 300.00 mistake but oh well, live and learn.  What size Taco pump do you think I need for the following setup:

Distance  from boiler to the shop: 70ft.... then I have a manifold that splits the hot water..one going to the domestic hot water heater exchanger.  Then the other path must travel vertical 18ft then horizontal 20ft to the stand alone unit heater.  Should I go with a Taco 011 or will I need a Taco 013 to over come the vertical rise? 

Thanks,

One other question.  Does anyone have a schematic or instructions on how to set this the fan so that once the water temp cools to say 160 that they fan will cut off.  This will keep everything warm for as long as possible instead of blowing cold air into the firebox as your wood gets low.

What is the purpose of the timer?

[mlappin]

Set the timer so the water has a chance to get up to temp before the low cut off can turn the fan back off.

The timer is a great way to do it. I had a similar setup on my first  boiler but I used a pushbutton and relay with a holding contact to keep the fan going till it reached the setpoint.

This seems less expensive and easier for me to understand for some reason.

Any thoughts on the pump size?  Taco 013 or Taco 011?

Also, does the Honeywell require the installation of the temp probe in the plumbing or can you utilize the one that is already there going to the A419? 
 

Thanks,

EE could you get me a drawing of what you are doing with the circ, i'm not sure i'm understanding the question, 2n'd the strap on aqua stat straps directly to the supply line from the boiler and has it's own probe that is inside it's mount.

Last Post for this thread . I finally got around to posting picture of the final setup.  Everything is working great and I am pleased with how comfortable the house is now...
