Greetings gentlemen,
I have a significant update. A plumber came out today and replaced my old cast iron baseboard rad with a newer slant/finn 30 model. It is much smaller than the old rad, and I have some concerns as to whether it will be strong enough to heat that room sufficiently.
I called the plumber and asked why he didn't install a model that was larger? The slant/finn 80? He said there would not be any increase in btu's as the pipe is only 1/4". I am not sure if he is being honest or just tried to install the cheapest model to pocket more cash. Claims there would not be any increase in BTU's given the pipe size.
This is a link to the slant/finn 30 manufacturer. They have the specs there. I measured the inside of this new rad, and it is a pipe with fins running along the entire length. I measured 5.5 feet from fin to fin.
Fine/Line 30 Baseboard
Do you gentlemen know if this type of rad would be strong enough to heat a room that is 10 feet wide by 11 feet long. 8 foot high ceiling. Bedroom with a double frame window, size 57"x57". Only one exterior wall.
I used a the slant/finn calculator they have on one site, and it said I require 8 feet. This guy only put in 5.5 feet of actual fins, which would emit heat.
I will contact him tomorrow. But he is not entirely keen on my questions, and I can't shake the feeling that this guy may have installed the cheapest rad, and did not get the sizing right for the proper BTU's.
Would really appreciate some feedback at this point. So much work has gone into arranging this with my building. I had plumbers come out. And now this guy, who claims has done many high rises here in Toronto. I am very suspicious as this new rad is much small and I can't see it being as strong as the cast iron base board panel that came out. I understand that he does many rad replacements. I could see how efficiently he worked. Highly skilled. So it stands to reason that he would put the right size in, if only to avoid call backs or complaints of insufficient heat. I do have that in mind. And yet I wonder how a smaller rad, can produce the same heat that my old rad produced.
I really hope this guy this did not screw me over. JTS had expressed some concerns about what may be behind that panel. Panel came off, nothing was in there. The wood backing was in very good shape. No rot of any kind. So that part is fine. He mounted this new rad quite nicely and the piping and fitting work was excellent. I just really have serious concerns about the output of this slant/finn 30 model , and whether it will heat a room 10x11. 8 feet high.
Thank you gentlemen,
