Re: Hoffman 2 Vents?
WIKA wouldn't lie ...
Honestly I was sure it was 10" Hg but after reviewing the picture and seeing 11" on the gauge I just could not resist

Re: Hoffman 2 Vents?
This is from the Hoffman Specialty Catalog for the Number 2 Vent.
"In systems using oil or gas burners, the number of operations of the burner per day is reduced about 25 per cent through the use of No. 2 Hoffman Vacuum Valves on the radiators and No. 6 or No. 16 valves on the pipe lines. In coal burning systems reduction in fuel consumption of 33 1/3 per cent is common."
They mention the number of burner operations is reduced about 25% per day. There is no mention as to what the reduction of total burn time is reduced per day.

Re: New Weil Boiler
Hey Triad my baseboard has a knob you can turn in the center of the top of baseboard which lowers and raises a full length damper. The knob turns a concentric ring with an arm that raises and lowers the damper.The damper is at the top of my baseboard and moves down to close the holes and up to open the holes at the top.

Snowmelt timelapse
I put together a snowmelt system back in june for my house in Colorado. We finally got some snow so i was able to try it out and i can report that my DIY project works, and works well i believe. My house faces north so it never gets any sun and was turning my sloped driveway into an ice rink. My wife fell once, i fell, but when the chinese food delivery guy fell that was the last straw so i started researching heated driveways. Through my research, mostly on here and Chris Deckers youtube i learned electric was not the way to go so I decided on hydronic. Anyways, thank you for all the information i found searching this site while i was building the system.

Re: Looking for review of my Radiant Heat Schematic
Here is the finished product. Its been running for about a week now. All the air bled out after 2-3 days and it is working flawlessly. The only pain was when I went to turn the boiler on for the 1st time it flashed a bunch of error codes at me. Turns out it was too cold to turn on (25F). Popped a space heater in it for a couple hours and it fired right up.
Thanks for all the help guys. You gave me the confidence to undertake this project myself.

Re: Riello noise
Oh, you're the guy from the other thread. If you need to replace the burner on a beautiful setup like a Buderus G115 with a Riello, then it's not the burner that needs to go, it's the service company. Are they aware it's not 1990 anymore?Northerners123 said:I’m wondering what that is? The burner is 10 years old. I am considering a Beckett to replace it they’re more common and practical for the oil service company.

Re: Beckett to replace Riello?
It's 2024. If a residential oil tech doesn't have Riello 40 parts on the truck, they shouldn't have a truck.
And if they can't handle Riello, they sure won't be able to handle an NX.

Re: Would a "remote Hartford loop" cause any problems?
No -- that should work very nicely. The only real trick will be to keep your steam pressure down -- a 48 inch loop is only good for about1.5 psi before the steam will blow through it.
Re: Why is my hotwater baseboard heat not very hot?
bb problems eh?
There are many reasons that would cause your problems. Let's give it a look...........Your aquastat [that is the devise that controls the temperature of the water in your boiler] should be set at 180*; Do you have a circulator for those two heating zones? Is it working? When the superstore was installed, did anyone make sure the boiler is capable of providing both heat and hot water at the same time? Those SuperStors are a great product, but ya gotta give 'em the BTU's. Maybe ya oughtta try shutting down the SS to see if the heat comes up. I'm going to assume you had the heat on this season already. Did it work OK before? BUT was the outside temp. the same. Normally, heating is sized to raise the temperature about 70* higher than the outside temp, so at 11* outside, you should be able to get about 80* inside. ONLY IF the BB was sized correctly along with the boiler and the SS
