A person named Nahsani recently posted the following on the alt.hvac
newsgroup:

"My two-year old Slantfin Boiler won't heat the house above 65
degrees, and it's usually at 60 degrees. It'll come on and off
randomly for short periods of time (as short as one second) and
over a long period of time, it may bring up the temp to 65. . . . ,

And, he later wrote:

"My old boiler was ancient - 50 year old, big. Then it puffed back
and wrecked my house. Anyway, I only replaced the boiler and the
pipes leading into it. It used to work fine (the new one).
Although my ex-boiler guy insisted that the on and off operation is
normal, I really think it's important. . . .,

I decided to also post it here in case anyone here has and ideas or
suggestions.

Dear Nahsani,

Is the thermostat actually calling for heat all this
time? Can you see on the display?

Do the radiators get hot at any point during the day,
or only a trace of heat?

Is there a circulating pump on the system?

Is there a Nahsani?

Lots of speculation on little info and what info there is doesn't
make much sense. N is MIA.

Yes, apparently Nahsani has "left the building".

Sorry for wasting everyone's time on this one. I decided to try posting
this here on alt.home.repair to help Nahsani. And, I only did so because he
was responsive in the alt.hvac group where he originally posted his
question, and he posted about 5 follow-up posts there in response to
questions and feedback that he received on that forum. If it were not for
his willingness to follow up on the discussion there on alt.hvac, I would
not have posted his question here. However, after I posted his inquiry
here, and I also followed up further on alt.hvac, Nahsani stopped following
up on the alt.hvac forum or here.

But, I do think that all of your thoughts and suggestions were probably
right on the money based on what he described as heater symptoms.
