Your the gentleman who e-mailed me

Your out on Long Island. I would suggest that you contact a trade professional out there. Rob O'Brien of Technical Heating is in your area he would be a great person to work with. You only get one chance to do it right so do it right.

Specific Questions are Better

I'm not trying to be inflammatory, but here's my perspective as a fellow DIYer who did most of my own install:

If you come to the Wall with very broad, wide-open questions such as your request "can you draw up a boiler diagram?" then you demonstrate that you are too far down the knowledge curve and the professionals here have to do the responsible thing and refer you to a trade professional for help.

If on the other hand you do all the research you can, work out your heat loss, design, etc., and have some very specific questions, folks here are very generous with their help.

There are places where you can find a variety of piping designs depending on what you would like to do -- I used ones that I found at Rehau's website for example.  There's a lot to learn about the various components and their functions and you can surely do a whole lot of reading and head scratching.  This is the value you get by hiring a pro, but even then, it's good to know what your system is doing and why.

There's also a lot to be learned by reading past posts here.  Just looking at the quality of work posted by the pros is a real eye-opener as to what a proper installation should look like.  It helps in translating the one line piping diagrams into actual three-dimensional systems.

Best of luck to you.

looking for a "LITTLE" help....?

Based on your verbiage, it looks like you are looking for a LOT of help.



Seek professional help. You are not taking on a small DIY project here. You are taking in a HUGE undertaking, that if done wrong, you might as well start burning money now.



I don't mind offering a LITTLE free advice, but you are asking for someone to completely engineer a system for you, and that is not within the purview of this web site.



Proceed with caution. You will be dealing with water, fire, carbon monoxide, gas/oil and electricity, and any one by itself can cause you a LOT of damage. Combine them together wrong, and you have a ticking time bomb. As RW said, you have one chance to do it right (inexpensively). Do it right. Then, if you have questions, you can come back and ask for advice.

boiler set

i'm going with this set up 11/4 primary loop with a 0010 pump ,coming off of that  is my 2nd loop and i'm going to reduce it to 3/4 with 007 pumps.my question is how far a part should the pumps be apart? with this set up should i be using mixing valve or mixing block? also would it be wise in using and outdoor reset?

problem number one

is you are never going to make a 175kBTU boiler efficient for your heating load without a sizable buffer tank.



other than that, what you are talking about is about as complicated as it gets. you are way over your head for a DIY project.
