looking to replace my oil furnace with a new oil furnace and heat pump. Suggestions?
Jun 23, 2008 by bhoutrosj | Posted in Maintenance & Repairs
I electrified in Seattle, WA and have a very old Oil furnace. Trying to make the house more verve efficient by using an oil furnace/heat pump combo. Does anyone have effect information and can someone suggest the appropriate unit sizes for descendants square footage? Thank you!
Oh and we can't provide to swap out to Natural Gas as we would have to overhaul our entire quarters and live far from the gas line on our street.
Sanction sure a Manual J load calculation is performed. Don't tolerate a Rule-of-Dumb sizing procedure. Also, have them counterfoil your ductwork to make sure it is sized decently and sealed to prevent air leaks.
To set the unit up becomingly to save you the most money on operation, your contractor will also poverty to calculate your thermal and economic balance points. There will be an alfresco temperature sensor that will send a signal to knuckle down d turn into off the heat pump and start the oil furnace. This also shouldn't be set at a indefinitely number "because it works ok". I'm true you're doing this to save money during the winter on your heating bill. Have them show you their amount and graphs to prove they know where to set the outdoor thermostat.
Heating oil contains more btus than propane. In my district, fuel oil is $3.23/gallon, Propane is $2.60/gallon, and electrifying with all taxes and misc bull charges comes in at $.10/kwh
Calculations for an 80% thrifty furnace and a Heat Pump with a Coefficient of Performance (COP) of 3.88 would be:
Ignite Oil: (1,000,000/138,000) x $3.23 / .80 = $29.26
Propane: (1,000,000/91,600) x $2.60 / .80 = $35.48
Heat Inspire: (1,000,000/3413) x $0.10 / 3.88 = $7.55 (47 degrees outside temp)
Fervidness Pump: (1,000,000/3413) x $0.10 / 2.73 = $10.73 (17 degrees face temp)
You can see by these calculations what it would cost to supply 1,000,000 btus for each air of equipment.
One thing to remember is as the outside temerature drops, the COP of the rouse pump drops as well. So, as it gets colder, it becomes more economic to switch to your oil furnace.
Another consideration is that the outside temperature will get to a stress relevant where the heat pump can no longer heat your assembly enough to keep you comfortable and this might occur before you reach the point where the Oil furnace costs less dollar-discerning to operate. Get a heat pump with the highest COP that you can spare. Brand doesn't matter. It all comes down to the institution.
If you find a contractor that will perform all these calculations, you will save piles of gelt during the winter.

What's important to consider in choosing an replacement oil furnace?
Jul 19, 2008 by ctmom05 | Posted in Maintenance & Repairs
We have plans to put in place of our oil furnace; it is old and inefficient.It is likely that we will stick with oil heat and the energized hot water heater that we already have, which is not too old.
What kinds of things do I need to have in mind about in choosing a new oil furnace?
first, is it quite a furnace, or is it a boiler? if you have hot air heat, it's a furnace, but many people with a boiler call that a furnace, too. if you have radiators and hot D heat, you've got a boiler, which is what i also have. that said, that is what i can give you some admonition about. one thing to consider re; your electric hot water heater is, how much it costs you to fervour your hot water with electricity. for not a lot more money, you can buy a boiler that will show hot water, while you heat your house anyways. depending on where you dwell, that's almost like free hot water, for better than half the year. this is called 'collateral hot water', and can pay for itself in just a few years. you'll have to put back your existing electric tank with a new holding tank, and your new boiler will have a tick circulating pump on it, to circulate hot water thru the new tank for heating the moisten. it's kind of like having a radiator favoured the new tank, that heats your hot water. as far as the new boiler itself, look into getting a formation iron boiler. two that i was impressed with were weil mclean, and dunkirk boilers. i would only buy a blade boiler, if money was a problem, or you were planning to promote the house within a couple of years, because they don't last as elongated as cast iron. also, check with fuel oil dealers in your yard, most will finance the job at pretty good rates. high-minded luck, hope this was of some help, and gives you some subsistence for thought.

How much oil should a furnace burn a day?
Nov 17, 2007 by fiesty312 | Posted in Maintenance & Repairs
I over recall my oil furnace is burning to much oil.
Well... vigour usage depends on several things:
1. The size of your knowledgeable in. The more space you have the more oil you'll burn (all other things being regular). Shut off unused rooms. If you don't hotness them you won't use oil to keep them warm.
2. The age/condition of your equipment. The older it is the more it will use, for 2 reasons. First, it may be in be in want of of repair/maintenance and second, new equipment is normally more efficacious. Consider getting a system tune-up or buying a new system if your is in actuality old.
3. The setting that you set on your thermostat. The higher you set the temp on the thermostat, the more oil you'll use.
3a. mull over getting a set-back thermostat. The more hours a day that you DON'T stress the house, the less oil you'll use.
4. The HDDs for your area. HDDs are Heating rank days. This is normally calculated by taking the usual temp of the day and subtracting it from 65 deg F. For example, if the ave temp was 20F (45 HHD) on Thursday and 40F (15 HDD) on Friday. You would have burned more oil on Tuesday than on Friday.
Once it gets depressing, oil usage has a fairly linear (straight in harmony) relationship with HDD....i.e., the colder it is, the more oil you use.
5. The amount of insulation in your refuge. If the house is older, it probably doesn't have enough insulation. Under consideration getting an Energy Audit and more insulation.
6. The amount of air leakage that your enterprise has. Your house "breathes" thru all of the snap around door/windows/other places. If you are serious about saving animation (which I'll assume from your question), consider having a "Blower Door Assay" done on your home. The test will identify the leaks and the technician will eschew you decide which are cost efficient to seal.
7. The acclimatize and amount of insulation on your ducts (forced air) or pipes (HW or steam system). If your furnace is in an unconditioned margin (garage/ unheated basement) you are wasting verve from your ducts/pipes in those spaces. If your furnace is in a conditioned span then this is less of a problem, but #8 is.
8. The amount of conditioned air (heated air) that your furnace sucks out of your establishment when it comes on. An oil furnace is a combustion device and must be properly vented to avoid it producing CO (carbon monoxide) and having the CO skip town into the house..... very dangerous.
Hope this helps.

I would like to convert my oil furnace by changing out the gun and installing a nutural gas gun ?
Sep 02, 2008 by farmnfly | Posted in Maintenance & Repairs
I seen a respond about "Wayne Industries conversion" which makes a guileless gas furnace gun? I cant find any info for this company or any other that makes a replacement (conversion) customary gas furnace gun. Heating season is quickly approaching. My furnace is a conjunction wood / oil and I want to keep it for the wood burning recourse. I only use oil to start the wood and on extremely cold days
Darn! I decent replaced my very old oil firing furnace (Richmond) that had been converted to a dual gas gun two wks. ago. Last winter I replaced the gas controller valve part of the gun. It was built by Honeywell. The only Achilles rejuvenate of the system was the millivolt thermostat in the house along with the millivolt generator that stuck out in the conductor flame. I was constantly changing out the generators.
I would strongly support you find a twin-shot burner with a 24 volt thermostat. Try: thomasnet.com and dig into gas conversion furnaces. Granger Industrial Deliver in another company to see if you can find other twin-shot gas valves for your furnace.
I was required and determined to have a Trane XV95 furnace and air conditioner installed but a resident installer thaked me out ot that brand. It seems that there are no local distributors for Trane parts in the courtyard. The closest was Rochester NY. We settled on a Tempstar which is the reward brand of Heil. There are two local suppliers of that label.

How long should an oil furnace last?
Sep 30, 2007 by Mandy and Melanie | Posted in Maintenance & Repairs
We have a 14 year old oil furnace and starting to have some problems with it. Wondering if it is notwithstanding to replace?
They can last for 20-30 years, depending on the status of the furnace. A good rule of thumb is that if the repairs are half the payment of replacing it, then you might as well replace it and get a warranty.

: $3,950.00 
UGI estimates that the average family of four will save $1000 to $1500 a year at current prices by switching from oil to gas. But it's not just today's prices that matter. Homeowners plunking down anywhere from $3500 to $9000 to switch their furnace to and more »
