    Not if it's running well. No reason to.

    The only reason to replace it is because you have a leaker. Maybe someone might say the old boiler is inefficient and you should upgrade to something that is over 90% efficient. If you do that, you will throw away something that may last another 20 years. The replacement will last 15 to 20 if you are lucky. The retail cost to you with labor and all the accessories to do the job the right way will save you 10% to 20% of your annual operating cost. The new ModCon boiler might be in the 5 figure price range. Now take 15% of your present operating cost and multiply it by 15. If that number is lower than the replacement ModCon boiler install price, then you will not break even over the life of the new equipment. Talk to your investment counselor or stock broker and see if he believes that is a good investment?

    You might start to place $50 a month into a “new boiler” account with your investment person. With the magic of compound interest, dividends and the rising stock portfolio numbers over the next 10 years, you will have more than enough to replace the boiler when it finally fails in 10 years or so. And you will have more than enough return on your money to pay the 10% higher fuel bill.

    The numbers just don't add up to replace a perfectly good operating heating system.

    Replacing a failed boiler with a new low efficiency boiler compared to a high efficiency boiler is a different story. If the $X,XXX.00 lower cost boiler is going to be a minimum investment anyway, then all you are comparing is the $2000.00 to $4000.00 difference between the low price and the high efficiency then, over the life of the Mod Con boiler there is enough savings to justify the additional price. But not enough to justify the full cost of the job when the existing boiler is still in perfect working condition.
