Re: Hot Water Boiler Rattling at Start of Heating Season
WoW that is impressive !!! Sounds loudest at the gas valve. Kind of wonder what the burner flames look like when that is going on. While it is happening I'd probably disconnect the wiring connector at the gas valve to see if it instantly goes away.

Re: Hot Water Boiler Rattling at Start of Heating Season
Here you go, looks like others had the same issue. As long as the 24 Volts AC is good at the gas valve, I'm starting to be convinced it is a bad gas valve.

Re: Reanimating Frankenstein - a gravity heat story
I never seen a gravity with TRV either , but I like the idea . It would solve all the house issues .
I would also add an outdoor reset control rather than using a thermostat . Make the operation work smoother .

Re: Gravity compression tank connection
If you use the bladder tank and have no circulator you can connect the bladder tank anywhere to the system or the boiler supply or return.
Re: Taco zone valve smoking
I think all taco powerheads smoke the first time you power them up.
Still remember the first on I ever did, thought I burnt one up for sure:>)

Re: Taco zone valve smoking
have been smoking for years when you first start them up. Then for the rest of their wonderful little lives they smell like they are burning and they get hot, that is a quick way to know if they are powered. Set the anticipators to 1.2 for better operation.

Re: Taco zone valve smoking
I will test the transformer. I am guessing that it is in spec, beacuse the older zone valves don't smoke, just the new ones. The gold power head did not smoke as much as the green power head.

Re: Taco zone valve smoking
I've only noticed the smoking this year ,maybe they have changed production methods.As for three valves on a transformer thats fine unless you have a house hold that wants all heat all the time then you'll be changing one head a year . When I attended a Honeywell sales pitch a few years ago the rep was able to show us all the math on this. But Honeywell 4 valves no problem .I change taco heads but install new Honeywell.

Re: Taco zone valve smoking
Well you may laugh but, I was told many years ago that it was due to the fact that Taco uses bee's wax in the head and any that may be on the outside will smoke off on the first cycle. i have seen it many times and have checked voltage and it is always with in tollerance.
