Is it worth it to change over to gas for both ?
If so any reBates or freebees.
You can call National Grid and ask about rebates and freebies, I would definately switch to gas it's more efficient and cleaner.

Quick answer: Yes! If gas is available.

Advice, don't take the 80% efficient furnace that LIPA has on special. It's worth paying extra to get the better 95% ones. An extra advantage is that you can retire your chimney (and cleaning) since the new ones are side venting.

Also, a HW tank that stores the water heated by the boiler is most efficient.

I converted from oil to a high efficiency gas boiler before last year's heating season. I also converted my electric stove to gas.

I believe the going rate for heating oil was $4.39/gallon. I typically used 1,000 gallons. So last year it would have cost $4,400.

My gas bill for the year (which now included cooking gas), was $2,200. Yes, I saved 50%.

The prior poster is correct - the boiler vents out the side or rear wall of your basement. One caveat - when the weather is cold, the boiler vents a ton of steam. It's not hot; you can put your hand against the outside wall and touch it. However, it is unsightly. So vent it out the rear of your basement if you can.

Good luck!

Right now, adjusting for BTUs, the wholesale price of natural gas is at a large discount to the wholesale price of heating oil, but should this price relationship prompt more use of natural gas relative to heating oil, then you can expect, over time, for the natural gas price advantage to become smaller, especially if natural gas should become a more popular automobile fuel, not to mention its growing use in electricity generation.

When i replaced the old gas burner i went with an 80 percent one. All the reviews I have seen for the higher then 80 percent ones from every company is the higher efficiency ones have high failure rates and can cost $500 and up to fix .

I figured the future repair costs would negate the savings between the 80 percent and 95 percent efficiency.

I do say make sure the 80 percent efficiency burner has a 2 stage fan if its a forced air system. That helps save electricity and also gives you a $250 rebate from lipa.

You're 100% correct. I researched this to death and the high efficiency condensing ones can cost a lot to fix and have major issues.

I have a contract with National Grid for my heat and A/C. I've had two parts fail and they replaced them for free. One of the parts was the zone water pump, which is unrelated to the type of boiler. The other was the fan unit, which failed a month after installation.

Are the high efficiency boilers less reliable? Old boilers were entirely mechanical and were highly reliable but did not optimize performance. New boilers have computers in them and determine output based upon many favors, including outside temperature, inside temperature, etc. Theoretically, the more parts the more change of failure. Even if so, I think it's worth it getting 15% more efficiency. If your gas bill is typically $2,000, a 15% annual savings is $300. For $300 one can buy a service contract (which you should have even on a lower efficiency boiler.)

I'd like to read the the links where you researched this.

Well This Saturday I will be converting to all gas. Since it's already coming into the house. Bye Bye oil. I am not using a LIPA contractor and I don't have to. The guy who servies my oil burner is doing it. I cannot wait.

I think you will like the savings, What kind of oil tank do you have (inside or inground) and are you having it removed as part of the conversion?

Best to deal with the tank now, it becomes more regulated and expensive to remove it every year you wait.

Good luck! What boiler did you buy?
