what is considered high fuel consumption

A monoflow system is not the problem don't let anyone sell you a repipe They are noy inhereantly more in efficent than any other piping arrangement , assuming it's working properly . Spend the money on what you really need . Find a Comfort Institute contractor (like me) who can come and do a blower door test on your house , find the leaks and fix them . You could get a more eff boiler but those aren't that bad . I would concentrate on getting the place tightend up.

I am living in south central Pennsylvania.

I am heating a 1500 square foot ranch with 1000 square foot basement. My furnace is a Peerless EC 103 121,00 BTU hot water output, Beckett model AFG oil burner, domestic hot water tankless coil piped into an electric hot water heater controlled by a L8124a honeywell triple aquastat and a basic thermostat in the main room on the main level. My system is a monoflo tee 1 1/4 inch main pipe with 3/4 inch risers feeding 146 feet of cast iron baseboard and 34 feet of copper fin tube. I have 1 taco 007-f5 circulator. Ihave used 130 gallons of fuel over the last 30 days. 1100 gallons last year during an 8 month heating season, October through May. Is this about what others are using to heat a similar sized home? Does the monoflo tee system cause higher fuel consumption than a series loop? Are there any changes I could make to my current heating system that would considerably lower my fuel usage?

How well is the house insulated?

In what condition are the windows?

Als got the start....

Is the envelope tight ? If so, there are quite a few things you can do to reduce the consumption of oil from there.

Outdoor reset and/or thermostatic radiator valves for the CIBB. How big of a circulator are you using? Is it too big for the size of your system? You can actually be pumping the water through your baseboards too fast, and they may not be getting the available heat to the rooms. The TRV's will act like a thermostat for each room, and with your Monoflow system are a perfect addition.

Many choices depend on a better description of your home and system. Chris

Read this article from Home Energy and calculate your relative efficiency. You will need to get the number of heating degree days for your area during your last heating season. Your local utility companies should have the figures.

I've stopped asking people if they think their fuel bills are "OK". I ask the actual usage since some think 1100 gallons/yr is ok for a 1500 ft farmhouse.

The few that complain either see their neighbor paying half as much with a new boiler, or the one guy that said his bill was well over $3000 for the heating season.

I haven't burned that much money in 5 years. Even apple for apple, his fuel use was higher than mine, but he wouldn't spend any money to save money. How shortsighted!

I calculated my energy use from the link you sent.

I live in an energy pig consuming 24.64 BTU's per square foot.

Assuming you mean 24.64 BTU/SF/HDD, yes, you would do better to tighten up the building envelope and insulate first, and then look at the heating system. You may be surprised at the gains you make.
