Here's the situation:

My dad's house is relatively new, built in 1997, so it is made from quality materials and well insulated. It's about 2200 sq.ft, not huge but not small either. In the summer, he runs the A/C all day long and it only blips the electric bill by about $60 each month. Conversely, my apartment which is half the size costs $80 a month to cool. I'd say he has an efficient system.

Now the problem for him is with heating. He has a high efficiency propane furnace, and for some reason that think chugs propane like its going out of style, and we can't figure out why. Around his area propane goes for $1.80 a gallon, and he had his tank filled about 5 times last winter at $650 a pop on average. The total for last year was $3,200 in propane charges just to heat his house, and it's not like he's running it on 90 the whole time. He had it set at 68, sometimes 70 if it was really cold.

My apartment has natural gas heat, and my off-season bill is like $10 a month for hot water; it goes up to $110-$120 in the winter when I run my heater. Figure about 5 months times $120, plus 7 months times $15 and my gas charges are $705 per year. I run my heater at 75, so my place is always nice and warm, btw.

Can anyone here tell me why my dad's heater is using up so much propane? Is this normal? I mean, we know the house and the ducting is well insulated, and the thermostat is digital and working fine. He had an HVAC tech check the unit out and it passed their tests without any issues. It IS a "high efficiency" unit too.

I'm doing some research for him on possibly getting a new system. Unfortunately, where he lives natural gas is not an option, so I was thinking about geo-thermal or oil heat...but I don't know if either would be cheaper...but yeah, paying $3K per year for heat is ridiculous if you ask me.

Are there any rooms which feel particularly cold? Does the air coming out of the vents feel hot?

How many floors is the home? Where is the thermostat located?

If it's a multi-floor home, look at closing the vents on the top floors. Some multi-level homes have a ventilation duct lever to adjust how the air flows. In the summer, cool air should primarily flow to the upper floors and in the winter, the air should flow to the lower floors. If the thermostat is in an area that stays cool, it will think the whole home is cool and turn the heater on. Also, close any doors or closets that are not needed or rarely used.

His propane bleed-off valve may have the laegenisi expansion. You need to have an EGS contractor install a control valve on the intake line that is monitored.

Goodluck!

Are you drunk? I am, but I can still type and error correct. Retype your reply as it sounds helpful.

Yeah the air is warm and the house heats relatively evenly. He already does that thing with the vents. It is a two story house, so in the summer he partially closes the downstairs vents and opens the upstairs ones, in the winter he does the opposite.

Now what's this thing about the propane bleed-off valve having some kinda expansion? I have no idea what that means. Does that mean it is somehow leaking propane into the atmosphere, essentially wasting it?
