My thermostat is pushed up to 80 but the temp varies between 55 and 63 depending
on how cold it is outside. This is with a new gas furnace and new thermostat.
It nevers goes over 63. The serviceman says my furniture is blocking the
radiators but it worked fine with my old oil furnace. Help??
You use the term furnace, but if you have radiators, it is a boiler
and different problems to diagnose.
Many potential problems. First is the size of the heater. Going from
an inefficient heater to a much more efficient heater allows you to
use a smaller size. The reason, an old 70% heater is putting 30% of
the heat up the stack, not into the house. A new 95% puts only 5%
waste, thus you can use a smaller boiler. The installer may have gone
too small. We need more information to decide that.
Blocking the radiators will have some affect and is easily remedied.
Move some of the furniture a few inches and see what happens. If no
change, it proves your point.
Since the thermostat is set high, the heater should never turn off.
The burner may cycles, but the circulator should never stop. Does it
cycle on and off? If so, it could be a defective limit switch, or the
circulator pump not pushing the hot water through the pipes.
You have to have the installer check for proper sizing and operation.
If the same guy comes out, he is too dumb to see the problem. Ask for
the owner to come out. There is a serious problem.
The homeowners hub guy from example.com got
a diagnosis from a real live, in person tech.
Not to be satisfied, s/he posts using a web
forum, invading Usenet to ask if the tech
who was there, in person, and does this for a
living is correct. My money is on the tech
being correct, the HO being miguided.

Have to disagree with you on this one, Chris. If the furniture is in
the same place it has been for years, the new boiler should be heating
the same as the old one.
As for getting on Usenet, it is a dying proposition. The major ISPs no
longer carry it and most internet users have never heard of it. Web
interfaces seem to be getting more popular Done right, I don't object,
but they should not be a vehicle to make money from our contributions.

As to the tech being right, given that the house was apparently
heated OK with the old boiler, furniture blocking the heat seems
like BS to me.
OK,that is a clue. On the boiler, there are settings for water
temperature. Evidently, it is not set high enough so while the water is
circulating, there is not enough heat in the water to give off to the
Water used to be set at about 180 degrees. Many new high efficiency
models will adjust the water temperature depending on the outside air.
You really need a competent service tech to set the system up correctly.
By now you should have been on the phone twice today asking for some
help from the people that set this thing up. If sized properly, you
should be at a comfy 60 to 70 degrees.
Call, be firm, get help.
How cold has it been?. It's been as low as 10 here and the furnace is
doing fine. My computer is in the basement and it only runs about half
the time, give or take a quarter.
Is it "colder than it ever gets" where you are now? It seems to me
there is something wrong with the thermostat or the furnace
installation, etc. that that is more likely than putting in the wrong
sized furnace, especially one that can only heat to 63, The BTUs and
other things are listed on a plate somewhere on the boiler or furnace.
Plus you should have an owner's manual that comes with a new furnace.
It says those things too.
Are there almost identical houses on your street? What size furnaces do
they have? Do you know what you used to have?
FTR, do you have hot water or steam radiators?
Is this a serviceman who works for the company that installed the new
I've never had a boiler, but since I put my computer in the basement, I
sit in the next room from the furnace and I can tell how much of the
time it's running. Folks, does that apply to boilers too? I would
If it were cold in my house and the furnace was only running part of the
time, I'd figure it was the thermostat or some safety device that turns
the furnace off.
If it ran all the time and still the house was cold (and there are no
more holes in the walls than when I had the previous furnace that did
work) I'd figure the furnace was undersized. Who told you what size
Assuming it's the size of the furnace:
If you told them what size you needed, perhaps based on what another
furnace salesman told you, and so they installed that size, that
complicates things. They may have some responsibility to examine the
size and see if it is really big enough, but I'm no lawyer and I don't
know what state you live in.
If they told you what size you needed, you're in much better shape.
Make sure you have saved in one place everything in writing that they
gave you. Print out any emails in case your hard drive crashes, Print
out any texts they sent you and any that you sent them, and all the
texts you sent them in also, because their emails and texts only make
full sense if a judge can see what you wrote too. , though aiui some
judges would rather see the texts in the phone, so don't change phones
between now and when you get things resolved. (Unless you keep the old
phone and the text messages in it.)
You should keep detailed records of what has happened, what you did,
when you called them, what you said, when they came out, what they did
and said, and what happens from now on, writing each entry right after
something happens. The more contemporaneous the better. If you used
text messages or email before, that's good, and use it more now, so you
have a written record of what is happening.
In theory any phone conversations of any importance can be replicated in
an email, You should be able to do this without antagonizing the
furnace company or making them hunker down by mentioning in passing what
they said but making the central point some question about what you
should do. Something you might have asked and forgotten the answer, or
forgot to ask.
If the people who sold you the furnace said how big it should be, they
may well have to replace the furnace with a bigger one, all or mostly at
their expense. A bigger furnace will have a higher price. You may
have to pay the difference in the price of the furnace -- I'm not a
lawyer -- but that will be small compared to the cost they'll have to
absorb, removing the small furnace and putting in the big one. I
suspect the labor to install the bigger one is the same or little bigger
than to install the firsrt one.
You'll probably need written estimmates from other furnace companies, as
well as written statements that the furnace now in your house is not big
enough to heat your house.
What would that do? Surely you are not one of those that sets it high
thinking the room will heat faster. The thermostat is nothing more than
an automated switch. It works just like a light switch. If you push it
harder does the light get brighter?
You also have to know the efficiency. A 100,000 BTU 60% boiler is equal
to a 65,000 BTU boiler at 95%. That should have been considered at
Yes, the burner will cycle according to the temperature of the
circulating water. The circulator pump will be on as long as the T-stat
calls for heat. It does not matter if is is set one degree or 30 degrees
above actual temperature, it works the same.
Of course not. Maybe the thermostat is broken and it's turning off too
soon. . But It really doesn't matter what the actual problem is.
I've learned to do every test possible, especially ones that cost no
money to do. Especially ones a poster can do with no help from anyone
Of course. I don't know if boilers come with a rated output. My oil
burning furnace did. OP, by size I was referring to the output. Sorry
I didn't specify that.
It should have been.
Your suggestion that the water temp is not set high enough would be the
easiest and cheapest to fix, and would only mean one mistake was made.
Two counting the fact that the serviceman didn't find the problem. But
we haven't heard back from the OP.
You seemed to assume it was hot water heat and not steam. Is that
because it's a house and not a larger building?
I was thinking that possibly it ran so quietly during one stage that it
could be providing heat but not obviously to someone in the next room.
LIke I say, I've never had a boiler. .
