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? * What
happens if it breaks in thh middle of winter? *I'll pay an arm and a
leg because it will become an emergency.

Or do I replace it during the summer at my leisure, even though
everything is working now.

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. *Alternatively, I can get rid of the
zone values and just have 3 circulator pumps put in, one for each
zone. *The estimate is about the same for that, or to replace the zone
valves with a Honeywell system.

Any advice? *Right now everything works. *I just don't want to be left
on the coldest day of thje year (these things always break when it's 5
degrees outside) with a broken boiler and I can't even get the parts
for it.

As for replacing the boiler, I'm not sure I'd get enough increase in
efficiency to make it back in a reasonable amount of time. *But then
again, is it worth it to replace all those controls on a 25 year old
boiler?

Again, if someone can help me figure this out, I'd appreciate it.
Thanks!

If the valves don't work, it's different than if the entire boiler
dies. WHich are you really worried about??- Hide quoted text -

I'm worried about the zones failing. Last time one valve failed, NO
zones
worked. I don't understanf why that is, but the plumber said that it
affects all the
zones if one fails.
