New Boilers

Steve_33

I recently replaced my boiler and it does not have a blow off valve. I called the installer and he said that newer boilers dont have them. So where the heck does the sediment go? Is this some way of guranteeing I call a tech out regularily to get the thing cleaned?

Is this

a steam boiler?

Is this a steam boiler?

or a hot water boiler...do you mean a pressure relief valve? I am guessing you are refering to a low water cutoff...and a blowdown proceedure...some of the newer set ups use a probe type set up which means you don't need the weekly blowdowns...the probe should be checked at least on a yearly basis for sediment...kpc

Yeah, steam boiler. This probe setup sounds like what I got. Not needing a weekly blowoff sounded too good to be true! I think now Ill invest in the auto fill so I can limit my basement visits. Granted, Ill probably go down and check things out on a monthly basis to make sure things are not out of wack.

auto feeder

steve be carefull a auto feeder will not maintain a proper operating level. what it provides is a safe minimum water level. a auto feeder is a saftey device not an operating device. you still should check your boiler water level regularly.

Joe is right on


If the hartford loop was installed for the "normal" operating water line, the probe LWCO may allow the boiler to run with a water line below the hartford loop. That can bring on what I call the "Big Ben syndrome".

Clanging and banging where there was none before.

LWCO's are safety devices and "auto-feeders" are too.

You still need to monitor the system.
