i need a plan for my project

maybemark

I have made so many posts, had got so many opinions, started buying materials, finding out from some people i should have gotten something else.
I need one person, who really knows about mod/con boilers. I will ask this person to make me a plan, and tell me exactly what to get. i don't expect this to be done for free. But i need help. And putting it on the wall each question, i might get 6 different right answers, but for me, it makes it very difficult for understanding.
who is the smart one, that has time to talk me thru this project of mine. i have a great plumber who is old school. Is not a believer in mod/con, but is willing to do the plumbing, as long as I have a pipeing plan, with all the parts i need, and where they should go.
Who's interested?

For those of you that have not seen my other posts.
My house is between 90 and 100 yours old. i have 2 layers of brick and 1 layer of clay block with plaster directly on the block. I have new windows, and new entry doors. i have about 16" of blown in insulation in the attic. i have a heat loss of almost 77k. I used a slant fin calculator to find out this number. I have an old converted gravity fed system. The system i have now is a way oversized 35 year old boiler, that is working but is killing me with my gas bills. i have 1 zone and that is fine with me. i have way too many radiators. On my other posts are the numbers of the raditors to the heat loss per room, SWEI and Gordy was nice enough to do the calculations for me
I already purchased a whn 085 radiator and a 40 gal DHW by Lochinvar. I started to purchase 1" materials for the near by boiler parts. i still have alot of materials to purchase.
I was a carpenter and general contractor but now i have been on disability for the last 3 years because of health reasons. My fund are little, and i need to take money from my line of credit to do this project.
Fred my good friend plumberwill be doing the work. he is an excelant plumber but he's old school and does not know about mod/con boilers. this is when i need a plan.
It was great asking questions on the wall, and i did get alot of information. But it became too overwhelming for me.
Originally, I asked somone to do what i am asking for now. he's a good man, i talked to him a couple tim3es on the phone and he helped me alot. but he is so busy and i have to respect that. I am so anxious to get this plan together, thou I will not be doing the project until march or april, when the weather is nicer.
I knew nothing about these boilers before i came to the site, and from these days i have been on the site, asking questions on posts, I actually have started to learn a little. I had ordered a book that Dan wrote (How Come) it was suggested by someone in one of my posts. My hope, is to learn more about boilers and the systems. To be able to learn enough, to tell Fred, we are going it this way.
I'm 60 years old, on disability, taking out a loan for this project, excited to learn, but I need someones help. i need just 1 person to make a plan for me. Some that will talk me thru this.
I know there are alot of very smart people on this site. And i have gotten alot of help. problem with listening with many, and purchasing materials, i hear from others, i should have purchase different things because they would have done it a more effecient way.
I started purchasing parts in 1" copper for the near by boiler.
Please help

these are the calculations that SWEI and gordy were nice enough to do for me, the unfortunate part, i am not smart enough to understand them.
Later on in that post, Gordy was able to help me understand a little about the numbers
System balance seems worse than I would have expected from the Dead Guys. The third column (ahem) here shows how many BTUs per square foot of EDR are needed to heat the room to the indoor design temp at outdoor design conditions:

EDR Heat Loss Btu/sqft
Living Room 227 15,565 68.6
Front Hall 30 5,496 183.2
Dining RM 51 6,279 123.1
M.Bed 39 6,065 155.5
Bed 2 30 1,360 45.3
M.Bath 21 2,353 112.0
Kitchen 134 7,351 55.1
Office 48 4,266 88.9
Powder RM 18 1,271 72.6


Kitchen 134 7,351 54.9

Those btu/sq ft numbers don't look right. How many total sq ft is the house?

maybemark

not exactly sure somewhere around 2400 or 2600 sq ft

Ironman

Well, at 2600 sq ft, that comes to just under 30 btu's per sq ft. Not bad for 100 year old house with uninsulated walls.

I don't know how you came up with the btu/sq ft numbers you posted.

What you're trying to accomplish is very simple and something that we do on a regular basis. I don't know where all the confusion is (I haven't read each post) but it's probably between each pro having his own preferences and your not understanding what they're suggesting.

I think your doing the wise thing in just choosing one to design it. But, a word of caution: once you choose one, don't post their design on here to be critiqued. That will only lead to more confusion as each not only has their own preferences, but most of us are very opinionated about them.

You've had a couple of offers by competent men. I'll throw my hat in to give you a third option.

P/M whichever of us you want help from.

Gordy

That's btus per sf of EDR "needed" for each room. Last column. Middle column is btu output at 150 btus sf EDR. 1st column sf EDR.

I think you know where i am coming from. There are probably several ways to do my project, and many of them will work good, some will work great, and others might not work. As you agree with me, posting my questions, I get alot of different answers, some the same, but for me that don't know, it's overwhelming. If your willing to talk to me off the wall, i would like that.
Gordy
Thank you for making it clear the calculations .I appreciate it.
Ironman, what gordy went and said, does it make more sence to you now?
thanks guys
I truely appreciate your words

Everything Gordy says makes sense to me.

Just P/M me with your contact info. After that, the first thing I'd like to see is some pics of your system.

maybemark

I'm glad what gordy mentioned makes sense. he's been very helpful to me from the begining

unclejohn

The help I will offer is this. Get another plumber that believes in mod /con boilers and you will be better off.
