I have a 25 year old Burnham boiler (hot water system) with 3/4"
piping and Electrozone zone valves (3 valves).
It's my understanding that parts are no longer available for my zone
valve system.

So here's my dilemma:
Do I just leave it alone until it breaks and deal with it then?
And then if I do replace, should I replace only the zone valves or
just replace the whole boiler? *I got one estimate (need to get more)
for $2100 to replace all the controls, or $4500 to replace the entire
boiler with brand new everything.

Key word here is the 25 year old boiler. *Gas or Oil? *What kind of
condition is it in? *My 30 year old was replaced two years ago, and I'm
saving 39% on my oil use. At 3.50 a gallon, that is $1200 a year.

Given that you have three zones, if one drops out you have minor
inconvenience, not a catastrophe. * Some other zone valve can be retrofitted
with minor down time.

Check what is available for rebates, zero interest financing and it may be a
good time to replace everything. *My System 2000 by Energy Kinetics is
paying for itself with fuel savings compared to my older boiler. *In a few
years, that money is going to be in my pocket, the some oil baron.

with a 25 year old system i would replace the entire thing, energy
costs only go up long term....

replace the boiler in mid summer, or if you want AC investigate
converting to forced air...
