Can someone explain how gas-fired boiler efficiency is measured? This
is for the baseboard hot water heating system in the house. I've been
at home all day this year and had the heat up so I expected a much
bigger heat bill. But no -- it has been right in the middle, and I have
records for the last 10 years. However, I seem to pay 50% more than
neighbors in similar houses.
That suggests the heat lost through the ceiling and walls is not the
major factor. So it must be going up the flue. My hunch is that high
efficiency is indicated by low flue gas temperature because all the heat
is being transferred to the water in the heating system. They must
check the CO and CO2 content, also, as a indication of total combustion.
Can anyone fill in the details? Thanks.
Thanks for the lead.
looks good, but a bit pricey for home use.
I would like to know the formula for converting the various measured
quantities to per cent efficiency. Of course, the air inflow will
affect efficiency, but what else? Have there been improvments, say in
the geometry of the burner, that have improved the heat transfer from
the flame to water in the boiler? Would replacing the boiler lower my
fuel costs for heating?
First off, HVAC Fella is a pedophilic moron....
More to follow...
The combustion analyzers test operational, as opposed to steady state
efficiency. Steady state is the efficiency over a set amount of time of the
whole unit, not just the combustion efficiency.
Not much else....
Yes, there has been improvements in burner technology.
Probably, but since we can't see it through the computer screen, we can't
You need to get a licensed, competent, insured HVAC company out to check
your system. Most of the new stuff will save you money, but only if they
are installed correctly and checked for proper operation.
HVAC fella only spouts what hears from the real pros. He ain't licensed in
his state (well maybe in his state of mind....).
If you don't want to tell us, remember what CBHVAC said. He checked your
state licensing board and found no evidence of any license in your name. At
least Stormin' Moron admits he's new to the field (and a hack).
