This may have been beat to death, but I have a "burning" question....
I have a Utica SFH3100WT boiler, equipped with a .85 80B nozzle, and
it's time for annual cleaning.
What are the upsides/downsides of downsizing the nozzle? So far in
January, the boiler runs between 4 and 9 hours a day -average about 6
1/2. Fuel is over $3.00 per gallon...... Hot water is OK - but coil is
probably restricted, and leads to hot/cool cycles in the shower.
Replace coil $$, or boiler $$$$?
Stat set at 68 deg F.
Would appreciate comments / advice before I talk with my burner guy,
who works for my fuel supplier.......
My question is:
Why are you wanting to downsize the nozzle? To save oil? Look at it this
(and this is not "exact science")
You downsize the nozzle, you're going to get less heat (BTUs). That means it
will have to run longer
to achieve the setting you want. True, you'll be burning less GPH, but
you're not really saving any oil
since it has to run longer. I know that is confusing sounding, but you see
what I mean?
Now, some boilers are designed to use several different size nozzles. The
Utica you are speaking of
(I'm pretty sure) does not. So as others have mentioned, it's not not going
to burn properly and you
are going to end up with a mess. If the unit is undersized, have a bigger
one installed. If it's just the coil that's stopped up, get another coil.
Better yet, get a new one off eBay and then you can TRY to get someone to
install it for you:
