Re: Troubleshooting No Ignition
When I look at electricity with my eyes, it seems fine also. I can hardly see any trouble. Like it is invisible until it gets to a light bulb. When that happens, I see the light!
In the case of a gas valve, there are a series of safety devices the electricity needs to pass thru. You can find them by following the wires. If all the different safety switches seem fine then you will need a meter to see if one of them is not so fine. ALL the safety devices need to be able to let the electricity get to the gas valve. If just one of the devices is not letting the electricity get to the gas valve, then the gas valve will not open to let the gas get to the burner. When the gas does not get to the burners, then there will be no heat.
Re: Horse Barn Radiant Heat
Therma-HEXX has been engaged to provide a radiant system for post surgery recovery horse stalls in a large animal, surgery hospital in New Hampshire. The task is to provide radiant cooling via the ThermaPANEL radiant ceiling system. The system will be a 12’x12’ overhead array for each stall. It will be cooled, and heated if needed, by an air to water heat pump which will be powered by the facilities net zero solar array. Dehumidification for latent control will also be implemented with positive pressure to each stall. Fabric curtains (outside of the horses reach) will allow air to flow outward. Urine will drain through a specially designed base material to french drains that can also be flushed with fresh water as needed. The main barn outside of the stalls will have venting cupolas.
We have also been tasked with radiant cooling of large indoor riding arenas with the capability of allowing the overhead panels to condense and rain on the dusty soil in the riding areas.

Re: Balancing
I completely changed every single trap not just the elements but the complete trap and adjacent piping. This system was super neglected over the years. The only traps I haven’t been able to get to are the bi metallic traps tied onto return @radiator in wall which subsequently are also the radiators that don’t get hot
Re: What the heck is this? This
the gauge glass is what makes me lean toward boiler return trap vs just an ordinary steam trap.
what kind of trim is on the radiators?

Alternating boiler return trap or "canned ham" Vapor system used to pump condensate back to the boiler with steam pressure.
Re: buying a hydronics business
I'm one of the old guys that started hydronics early, before PEX became popular and only serviced existing systems as there were very few new systems being installed because of copper failures.
After PEX became available and we started installing new radiant systems, once I got a customer, I wrote his name down in my address book . I coveted those customers because I loved hydronics and knew that when I got older and couldn't install new systems anymore, I'd want to do service and repair work. Excellent work if you know what boilers are popular in your area and what parts to keep on your truck and how to charge to make a profit.
Those customers are now calling me with broken boilers and I can still replace a boiler. Your old guy's customer list - if it's real and current - along with his phone number is golden. And if you can get him to ride along in your truck or at least visit your job sites would be a bonus. I would encourage you to see if you can come to an agreement on price. What he's asking is too much.
Re: Need new boiler
Every so often I get called for a second opinion on wether a boiler needs replacement or not. Seems more often than not I tell the customer that while a new setup would save fuel, their boiler is in fine shape. What I find amusing is that sometimes the customer does eventually decide to upgrade and he gets us to do it instead of the company that said it needs replacing.

Re: buying a hydronics business
For the large amount I would want to see his client list, and financials showing what he has paid himself.
Do you get the company name and phone number?
How many hours a week does he work for that salary?
Tools, truck, inventory?
40 hours a week, 50 weeks a year= 2000 hours
So you need to add at least $50.00 and hour to your labor rates just to pay him
If all three if you want 100k a year, $150 per hour per billiable hour just for salary.
Its doubtful you will have that many billable m, productive hours a year, so maybe pushing 200 per hour
Here is a really good deal 😁 to maybe help with some number crunching
