Oil furnace / tank questions...

Good Luck eh.
Hi Yuri,
Yes, I will look into what incentives Hydro-Quebec has to offer. I do know that they have a preferential rate for customers who have Dual energy installations.

If your tank is at risk of leaking and you think you'll have an oil furnace new or old it might be best to get a new tank swapped in regardless. That will buy you some time to decide.
Great, thanks for all your guidance. I'll start getting quotes.

Yup, that's me on Reef Central
I have a 125g tank (240g setup) & a 300g tank waiting on completion of the addition

= $19.98
At $4 a gallon (last year) = $24.84

16 SEER 3 Ton Goodman Heat pump with electricity at 14.6 per KWH, C.O.P. = 3.5 at 35F (1.6C):
(1,000,000 / 3413 btu per KHW) x 0.146 / 3.5
= $12.21
At 16.6 per KWH = $13.90 still pretty good

Electric resistive heat (always 100% efficiency) with electricity at 14.6 per KWH:
(1,000,000 / 3413 btu per KHW) x 0.146
= $42.78 ??

I would guess somewhere around 20F (-6.6C) your heat pump will not be able to keep up with dwelling heat loss and your furnace will begin to supplement.
I adjusted the figures for my numbers
I guess full time electric heat is defintely out for me
Heat Pump is cost effective, I wonder what my friends problem is with his setup. Maybe his electric is higher
Interesting & Thanks for the figures & information
We need a new boiler too
But we only use just over a tank of oil a year
That will change once the addition is completed

Can a heat pump turn on an oiler boiler instead of electric heat as a backup? That would be much better
Of course then we would need a new boiler
I'm not sure how both systems could interact & heat the house

Any info on Gas heat?

Oil furnace / tank questions...


Update on the situation:

I had my oil company come take a look at the discoloration of my oil tank, pictured in the first post of this thread... He said that it was nothing to worry about, _it's not a leak_, however being that the tank is now 32 yrs old, it should be replaced ASAP.

I have since sourced 3 quotes.

COMPANY A - (who is currently my oil provider, and whom i have a maintenance contract with)
Oil furnace:
- Brock MBP-1 with Riello Burner
$2925
- New Oil tank
$1285
- Optionally a heat pump would be about $2500 more.

Electric furnace:
- ICP - Supreme
$3295
- Oil tank removal
$300
- Relocation of inner A/C coil
$450

COMPANY B
Electric Furnace
$4065 (forgot brand, and model)

COMPANY C
Electric Furnace
- Carrier
$2800
(includes removal of old oil furnace and oil tank, and pumping old oil, as well as closing holes in foundation)


Looking at the above prices, you'll see that I've decided to go with an electric heating source seeing how it is necessary to replace (or remove in my case) the oil tank anyways. I'll be going with Company C. This will also allow me to win back some lost space in the garage that was previously occupied by the oil tank. Taking into account that oil prices and electric prices are just about even in my area, and that oil prices are only bound to go up, the decision was easy.

Unfortunately, since the tank is 3/4 full, I'll lose all that oil when it's pumped out. Apparently nobody offers a credit towards the used oil since it has to be filtered before it can be put back to use. Also unfortunate is the fact that I just signed a maintenance contract a few weeks ago for my current oil furnace, which I most probably won't be able to cancel...

So that's where I currently stand... The work will probably be done sometime in August.

Ask Company C say about waiting until you draw off some of that oil in the fall - perhaps when you get under the hundred gallon mark, or less. With a deposit and signed acceptance they may be fine with waiting, especially if that is a slower time of the year for them. Plus that's less oil for them to deal with.

They probably wouldn't have any issues with that... however I'd rather do the work sooner than later so that I no longer would have to worry about a 32yr old oil tank that may decide to spring a leak at an inconvenient time...

Then offer the spare oil up on craigslist for best offer. Buyers responsibility to pump and take oil.

That's weird, I've seen companies that will come & pump out the tank & pay you. It's not the same as the cost of the oil, but it's something
Some people around here offer the oil for free
Someone always takes them up on the offer
I picked up about 50g from a friend who switched to gas

Well, technically, company C is not charging me extra to pump out the oil and remove the oil tank/furnace...

So I get 2176 HDD at the airport, 56 days and 2640 kwh at an efficiency of 100%.
Could I get your sq. footage including the basement?
I'm doing some stats on heat loss. Average is 6 BTU/sq. ft./HDD. Here's what I've got so far.

Ranked
1.7 least heat loss
3.8
4.0
4.4

11 most heat loss

Range 1.7 to 11
Median 5.0

I think company C is giving you a very good deal. Apparently you cannot just throw old oil tanks in the dump/scrapyard. Have to be disposed of according to environmental laws. For what they are charging you I would let them take care of the whole mess.
