Heating Oil Spent for Nothing?
 
Could somebody please explain to me the following. I have a pretty new furnace used for heating only. Guys from my heating oil company explained to me that I had to keep it on even during summer months. So I did, and I noticed that during the period from June 18th to October 31st, I spent 48.3 gallons of oil (at least this is what the bill says). It seems to me that it is too much only for keeping certain temperature within the furnace. Is anything wrong with my furnace or with this practice of keeping the furnace on when it is not used for heating?
Thank you in advance.

Is this a furnace or boiler?

I believe it is a boiler, because I have baseboards. So this thing is heating water.

Unless its a battleship or you live in Alaska I think something is wrong or at the very least Miss Understood.

Almost 50 gallons of oil at 3-4 dollars a gallon for heat in the middle of the summer?

I cant see why....

I would think the heat system should have been shut down in that period.

does your furnace supply hot water for showers, dishwashers and everything else in the house...mine does and I used about 35 gallons of oil over the summer. One fix is to buy and electric hot water heater for use in the summer

Actually, it is not for heat. It is just for keeping certain temperature inside of the boiler. The thermostat was at 0. If I am not mistaken, the guy said otherwise the boiler would get rusted (I am not sure though that I remember correctly).

No, it is used only for heating. I do use electric water heater for domestic water.

I'm not a boiler expert but hot water versus cold water would have the same amount of rust.

How old is your boiler? I recommend to leave it on all the time. In the summer you can lower the temp so it will just keep the water warm. Reason for this is the cast expands and contracts. When you turn it of for the summer it contracts and you could start to get leaks and rust building up. If you maintain a warmer temp it will keep the cast warm and it won't be expanding and contracting and no leaks. A newer boiler you won't really have to worry to much about it, but over time the gaskets will get older and start to dry out. So in a nut shell turn the temp down on the stat in the summer no need to maintain 180* water in the summer. 80-100* would be fine and it will use less oil. Just don;t forget to turn it up it the winter.

It is just 2 years old.

No real need to maintain temp in it during the summer.

Steam boilers don't maintain temp in the summer.

Oil companies like your money though.

What if I don't use the boiler even in the winter for some reasons?

Is my boiler a steam boiler?

I doubt it.

Does your boiler need a circulator to circulate how water to the rads/baseboard. Then its a hot water boiler.

It's not that I don't believe you Bervin but I just can't understand how it would be ok to drop 100 degrees from 180 to 80 and not have contraction/expansion issues but if you let it drop anoth 5 degrees to 75 then problems spring up????

How does that extra 5 degree drop affect things but the 100 degree drop doesn't?????

Depending what brand and model boiler it is.
It doesn't have any gaskets either.

If it does have a blank plate for a tankless coil.
The savings in oil, will pay for a gasket change out, with plenty of money left over.
