BOILER SIZING QUESTIONS W/RAD PICKS

Smaller supply houses have straight pieces of insulation, and you can use cold water paste for the elbows and fittings.

BOILER SIZE/RAD QUESTIONS W/PICS

Hey Guys,I got some great answers for my prior questions, I would like to go over a couple of things before i go ahead w/a boiler install. I am looking to replace a Burham #405 w/sq ft rating of 350, The house is a single family brick home semi detatched w/a full finished basement, 1st fl, and 2nd floor, and a flat roof. the existing radiation connected to a one pipe system consists of the following.
-Master Bedroom 2nd fl- 1-"American Radiator" 8" wide, 26" high, 5-Tube, 11 sections, at 3.5 sq ft.per section= 38.5 sq ft.
-John's bedroom 2nd floor- 1-American Radiator 8"wide 26"high, 4 tube, 4 sections at 3.5 sq ft per section=14 sq.ft
-Jenns bedroom 2nd floor-1 American Radiator 8"wide, 26" high, 5-tube, 9 sections, at 3.5 sq.ft per section=31.5 sq ft.
2nd fl bathroom, Lokks like a Burnham radiant, 5" deep, 20" high, 13.5 inches wide, 6 sections at 2.25 sq ft. per section=13.5 sq ft.
1st floor Living room- Burnham radiant rad, 5" deep, 20" high, 49.5 wide, 22 sections at 2.25 sq ft. per section= 49.5 sq feet.
1st floor living room Burnham cast iron baseboard, "baseray", 2.5" wide, 10"high, 10.5 feet long at 3.40 sq ft per linear foot = 35.7 sq ft
1st fl bathroom, 1 American Radiator, 20" high, 5" wide, 4 tubes, 6 sections at 2.25 sq ft. per section= 13.5 sq ft
-Kitchen Burnham radiant radiator, 5" deep, 20" high, 22.5" wide 10 sections at 2.25 sq ft per section= 22.5 sq.ft. No picture of this rad
-Pantry- 3 foot piece of Slant fin steam baseboard, 4.1 sq. ft. per section= 12.4 sq ft.
1- Basement ceiling hung radiator, Niagra Radiator Co. single column, 22 sections, 46" long, 15" wide, 2" thick, at 1.5 sq ft. per section = 33 sq ft. Thanks to Steam Head for this info.
Toatal comes to 264.1 sq ft. of radaition, I just want to make sure I will be ok with a Burnham IN4 w/a rating of 271, sq.ft. I will do my best to insulate as much of the heager and mains as I can, the house has had new windows installed and more replacements will coming in the future, the house is of brick construction so I dont think there will be much insulation in the walls, but the house will be re-stuccoed within the next year or so, if that matters any. The basement has been re-framed and isulated properly. Thanks again guys for all your help,

You'll do fine

with the IN4's capacity. No need for a bigger boiler. If you want something a bit more efficient, the Smith G-8 3-section steamer is a good choice, rated at 283 square feet.

Thanks again for your help Steam head,I will look into the Smith G-8 3 section, Any idea where I can purchase some pipe insulation that will fit over 2" steam fittings? el's, 45's, unions, tees, etc? I have been trying searchiing out some web sites but haven't had any luck. thanks again.

Any good insulation supplier

should have them in stock. Some don't sell to the general public, but if that's the case your contractor could get them.

Here's a pic of a G-8 we installed recently- it's a 5-section though. Besides its higher thermal efficiency, you can burn oil in it too if you wish- the factory supports its use with either fuel. A pro could change it over.
