With accessible heating oil prices high a couple of months back and I create they will go back up soon, can you burn Crisco in your oil furnace. Its about half the fee of furnace oil.

Looking for the specs on Furnace oil and Jet b aviation fuel?

Oct 05, 2008 by Clay M | Posted in Maintenance & Repairs

My uncle has been afire a mixture of jet b and fuel oil in his furnace, I recommended against it, but need to show him what could prove if he continues.

Oil is 144,000 btu per gallon per hour and depending on the effeciency. Jet B is hotter but the mix should be ok as my torpedo heater is rated for both.Also if it overheats the exalted temp limit will shut it down.

what is the specific heat of heavy furnace oil?

Dec 12, 2006 by Krishna | Posted in Chemistry

i would like to conscious the specific heat of furnace oil, so that i can calculate how much calories it would take to hot up the oil from 70degc to 115degc.Pls help.

The equation for crafty the specific heat of furnace oil is:
Cp = 4.876 + 0.0009(t-15)
where Cp is in cal/(g*°C) and t is temperature in °C.

To get the vivacity required to heat the oil, we need to integrate that equation:
Cp[115°C, 70°C = 0.00045t^2+4.8625*t
0.00045*115^2 + 4.8625*115 = 565.14 cal/g
0.00045*70^2 + 4.8625*70 = 342.58 cal/g

The imbalance is 222.56 cal/g
This is is the same is 222.56 kcal/kg or 931.8 kJ/kg or 400.6 BTU/lb
The density of heating oil is 0.72 kg/L, so the determined heat with regard to volume is 160.2 kcal/L or 670.7 kJ/L or 2406.48 BTU/gal

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 get along in Seattle, WA and have a very old Oil furnace. Trying to make the house more spirit efficient by using an oil furnace/heat pump combo. Does anyone have upshot information and can someone suggest the appropriate unit sizes for lineage square footage? Thank you!
Oh and we can't furnish to swap out to Natural Gas as we would have to overhaul our entire domicile and live far from the gas line on our street.

Do sure a Manual J load calculation is performed. Don't stand a Rule-of-Dumb sizing procedure. Also, have them authentication your ductwork to make sure it is sized aptly and sealed to prevent air leaks.

To set the unit up decently to save you the most money on operation, your contractor will also privation to calculate your thermal and economic balance points. There will be an out of doors temperature sensor that will send a signal to mutiny off the heat pump and start the oil furnace. This also shouldn't be set at a incidentally number "because it works ok". I'm satisfied you're doing this to save money during the winter on your heating bill. Have them show you their deliberation and graphs to prove they know where to set the outdoor thermostat.

Heating oil contains more btus than propane. In my close, fuel oil is $3.23/gallon, Propane is $2.60/gallon, and moving with all taxes and misc bull charges comes in at $.10/kwh

Calculations for an 80% effective furnace and a Heat Pump with a Coefficient of Performance (COP) of 3.88 would be:

Eagerness 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 Push: (1,000,000/3413) x $0.10 / 3.88 = $7.55 (47 degrees outside temp)
Stress Pump: (1,000,000/3413) x $0.10 / 2.73 = $10.73 (17 degrees skin temp)


You can see by these calculations what it would cost to supply 1,000,000 btus for each uniform of equipment.
One thing to remember is as the outside temerature drops, the COP of the torridness pump drops as well. So, as it gets colder, it becomes more competent to switch to your oil furnace.
Another consideration is that the outside temperature will get to a show where the heat pump can no longer heat your legislature enough to keep you comfortable and this might occur before you reach the point where the Oil furnace costs less dollar-about to operate. Get a heat pump with the highest COP that you can yield. Brand doesn't matter. It all comes down to the station.

If you find a contractor that will perform all these calculations, you will save piles of moolah during the winter.

What's important to consider in choosing an replacement oil furnace?

We have plans to change our oil furnace; it is old and inefficient.It is likely that we will stick with oil heat and the thrilling hot water heater that we already have, which is not too old.

What kinds of things do I poverty to think about in choosing a new oil furnace?

first, is it in point of fact 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 sprinkle heat, you've got a boiler, which is what i also have. that said, that is what i can give you some warning about. one thing to consider re; your electric hot water heater is, how much it costs you to warmth your hot water with electricity. for not a lot more money, you can buy a boiler that will transform hot water, while you heat your house anyways. depending on where you tangible, that's almost like free hot water, for superiority than half the year. this is called 'zigzag hot water', and can pay for itself in just a few years. you'll have to supplant your existing electric tank with a new holding tank, and your new boiler will have a alternative circulating pump on it, to circulate hot water thru the new tank for heating the bottled water. it's kind of like having a radiator middle the new tank, that heats your hot water. as far as the new boiler itself, look into getting a actors iron boiler. two that i was impressed with were weil mclean, and dunkirk boilers. i would only buy a sword boiler, if money was a problem, or you were planning to put across the house within a couple of years, because they don't last as fancy as cast iron. also, check with fuel oil dealers in your space, most will finance the job at pretty good rates. adroit luck, hope this was of some help, and gives you some viands for thought.
