3 companies I have always admired
LAARS, Bradford White and Electro, under one tent now.
I remember years ago when the CEO of Bradford White would do presentations at plumbing wholesalers. When they decided to go through plumbing wholesalers to market.
Same with Electro Industries, find the top brass at trade shows to answer any questions.
Avy Miller started LAARS in 1948, named for his family, wife Roberta, and 3 daughters Lindsey, Andrea, Stephanie.
Starting out in the pool heating business, they became the go to boiler for early radiant systems and snowmelts. Still a good option for snowmelt systems. Copper is second to gold for heat transfer:)

Re: Does anyone know what this is above the boiler flue?
I believe that is/ was a tankless coil.

Re: Newer single-pipe steam radiator not heating this season
When the boiler comes on for a call for heat and it starts steaming check the vents to see if they are venting air.Just kicked on the heat and hung out by the radiator for a bit. I can indeed hear a steady stream of air coming out of the vent on the radiator in question. Waited long enough so that all other radiators are piping hot, but this one remains only slightly warm on one side with air continuing to escape from the vent at a steady pace.
If the rad worked before it should work now
Re: Circulator pump very hot
Air bound? That is a water lubricated pump and the boiler water is inside that section of the pump, but the stator windings are between the water and the green metal case you are measuring the temperature of.
Or the pump is stuck and you are just melting the windings on there.
I'm guessing you have no heat on that zone?
Nailed it!
Re: Want to Start your own HVAC business?
As an added incentive, you not only get Frank's 40+ years of experience, you also get a great, established for generations of experience, and reputation to help you grow and earn big profits. My cousins and brothers learned the trade and how to grow a business from our fathers. It's like getting the secret recipe from Colonel Sander's for the secret 11 herbs and spices.
Here is a picture of the first Service Agreement that helped grow the F.P. Young company in the 1950s to become the largest independent Fuel Oil Dealer in Philadelphia by the 1980s with over 5000 automatic delivery accounts.

Re: Snowmelt timelapse
@Burnett03Yes everything was DIY except for pouring the actual concrete. Here are a few more pictures.
You're a do it yourself!?
Kudos to you on a job well done!
Re: Steam boiler not cutting out
When looking for possible pressuretrol plugging make sure the small hole at the base of the pressuretrol (or vaporstat Inside the brass fitting) is clear. That can get gunked up stop it from trading the system pressure.
I worked in Watertown for over twenty years as a technician then in engineering, and a mile so down the main drag was Doble Engineering , That's the same outfit that developed the Doble model B steam can over a hundred years ago.

Re: Solar paired with phase change material
How about a thermal battery bank using Sodium acetate trihydrate ?
Each Battery can be utilized/Triggered when needed.
I think Sometimes potassium chloride and/or sodium chloride was also utilized but i think the Heat exchanger design may be challenging.

Re: Snowmelt timelapse
Luckily, there's no such thing as "climate change." Using heat to melt snow instead of going outside with a friggin shovel for 5 minutes???!!!! If you can't shovel one inch of snow, Colorado is the wrong place to live.@philsego, this comment is uncalled for and antagonistic. Why start your day by tearing other people down? Please follow site rules and be respectful. You do not know the OP's situation or why they chose a snowmelt system. Snowmelt makes a lot of sense for CO and they're sharing this video because this is the first snowfall to test the system out. It doesn't matter how much snow they received. I appreciate them sharing the video so that we can all learn.
Re: Radiant floor performance troubleshooting
The main reason that residential radiant floors design around a 10- 15 delta is for comfort. You want the floor temperature to be a consistent as possible.
If you run in that 10- 15 range when you reach thermal equilibrium ( supply and return temperature stabilizes) , all is good.
This shows what a 300' loop would look like running 3 different delta Ts. Same 110 supply temperature in 3 examples.
