I'll try to give as much info to start. I have a classic 5036. I am plumbing it to two buildings. Each building is pumped continuously by 007 pumps mounted on the boiler. The 1200sq' house is as follows. 75' of 1" thermopex to the house. 25' of 1" to the thermostatic valve. 15' of 1" to a 30plate w/w (for pool) then 10' of 1" to w/h side arm then 25' of 1" to forced air furnace with 100k btu w/a then back to boiler. All is in basement.  The 900sq' garage with 10' walls is as follows. 50' of 1" thermopex to garage. Into thermostatic valve. 3/4" line to mixing valve to 007 pump to manifold feeding 3 runs of 300' of 1/2". Does this design seem right for each building? Wondering if I should have plumbed the w/w for the pool with a bypass option to reduce plumbing during heating season? I did a bypass for furnace so we could heat water longer than the heating season. For the garage is the single 007 good for the floor runs? Floor temp in 140 and 80 out.

You only have one pump on the building with the floor heat and no pump at the boiler?

I would check the return temps on the house loop. A 007 sounds like it would be way too small for what you described.

Was the 30 plate sold as a pool heater? Is it brazed? Pool water isn't compatible with brass so you will want to make sure it is meant for heating a pool.

Good Points RSI, Agreed all the way!

Both buildings have a 007 at the boiler pumping all the time.

The house does NOT have another pump. It relies on the one at the boiler to push everything.

Should I add a second pump for the house?

 The garage has a 007 inside which pumps for the floor when heat is needed. That pump pushes 3 runs of about 300' of 1/2". 

I asked my boiler guy for a unit to heat the pool and that's what he suggested.  But the more I buy and questions I ask I'm starting to think I know more  about the setup than the dealer.  He said he just sells boilers and plumbs the outside. He sells everything else but has nothing to do with it. Which leads me to believe he doesn't have knowledge of the parts he sells.

I think I can add pics if needed.
Thanks

That's a big load for that stove IMO. Not many dealers have good knowledge like what you can find on this site. Hopefully you can return some parts and let these guys get you straightened out. That stove should work for your house and garage. Pool, not sure. Probably take a lot of wood.

The pool is only summer time use with boiler. I figured since the boiler was here use it. And we only fire it up for the pool every once in awhile.

The boiler seems to use a lot of wood for the buildings. Some night when really cold it won't make the night on a firebox packed full.

What is the best way to determine return temp? I have a infra temp gun but it doesn't seem accurate. I believe if we can get the return temp up it'll reduce wood usage.

I've been reading a lot on here and wish a would have found this forum before I started.

Just feeling the pipes will get you a better estimate on return temp than an infrared thermometer.

The pumps are probably fine on the building with the floor heat.

If you are getting decent return temps on the house loop then you can leave the 007 but I think you will need a minimum of an 0015 and may even need to go up to an 0011. (an 009 would also probably be ok)

You don't have to stay with Taco either. There are a lot of other options.

Would it help to add a by pass to the w/w for the pool in the off season?
Should I  go with a larger single pump?  Or add a second one inside the house?

The garage with floor heat has a mixing valve. I've played with different in temps (110-140) but only get 80 out. 
Is that ok? I assume the thermostatic valve must allow some to return to boiler even if up to temp because the return seems hot even with only 80 coming out of floor.

[RSI]

You can add another pump. I would go with a 0015 though as the 2nd pump.

Is the pool heater in a heated area or could it freeze? If you are not using it there is no point in running water through it unless it needs freeze protection.

How do you have the plumbing setup for the floor heat? Can you post a diagram or photo of it?

[lmann]

Should I add the second pump right after the thermostatic valve inside the house?
Pool heater is in line in the basement with everything for the house. So I could bypass it.

If I bypass it would I still need a second pump?
It would only be w/h sidearm and the w/a in furnace.

I'm using my iPhone for all this so I'll try to post a pic of the garage floor heat.
But as discribed once it enters the garage it all mounted together on a board. It enters into the thermostatic valve then to the mixing valve then pump then manifold for the three runs.

I can't get the picture to load to the forum. Can I send it to you another way? Email?

[lmann]

Can I email my garage floor setup picture to anyone? Or can anyone tell me how to get it loaded to here. It says file folder is full. I've tried shrinking it with no luck.

Unfortunately full means full, try posting your pics on Photobucket, Flickr, etc then post the links to your picture here.

Ok thank you.

If I did it right this is a picture of my garage floor setup.
