Hot water issue - furnace ?

swnoel · 04-01-2017, 06:11 AM

I would suggest you do not replace the coil on a 30 year old boiler... putting $1000-1200 into a boiler that old is asking for trouble! Especially if the boiler decides to leak shortly after you spend the money! As has been suggested, either install an indirect or stand alone tank, either electric or if you already have propane, a power vented one. You can check if the coil is the problem merely by drawing hot water and grabbing the hot side of the coil... is it blistering hot or does it become out warm. It better be blistering hot! Please stop calling boilers furnaces... there is a DIFFERENCE!

Here is one thought....
#1. Do you like your place at the lake?
#2. Do you expect to own it for at least a few more years?

If so, spend the money and replace the boiler completely. Not usually a huge job and most likely under $5000. Be done with all the fooling around. Given its current age, it is likely on life support anyway and you will have to replace it at some time in the future. If you sell at some point, it will be a selling feature. At least look at this alternative before making any further decisions. Get three quotes to do the job.

My new boiler was $3k plus the install costs, which ended up being beer (I had a friend install it). My old one would have needed almost $2k in repairs and it was older than me.
