In floor heat bolier type

Believe it or not, industrial plants that use huge amounts of energy in their processes are very cognizant of their energy costs. Energy costs are what make or break a plant as far as profitability goes.

The fact is, though, that producing steel from iron ore, for example, requires energy to cause a phase change from solid to liquid. That’s physics.

I couple years ago I was in a large food processing plant. A heating contractor asked me to look at their boilers. I walked into the mechanical room and never wanted to run and get the hell out of there. The contractor just laughed. He told me he wanted me to see the poor condition of their boilers and they would not let him spend any money to repair and service them. It was horrible. All of them should have been red tagged and shut off, but of course, that would have shut down the plant so that wasn't happening.

Concerned about efficiancy? Not remotely concerned, all they wanted was hot water.

If you need DHW, the Weil Mclein aqua balance is price right providing it comes with warranty. One thing not mentioned is with high efficiency boilers having fresh air intakes, the concerns over fuel vapor ignition from the boiler is removed.

you get free unlimited NG and want to spend 4k to save what exactly?

Lol trying to be a little thoughtful to the environment plus if I lose my gas and have to go to propane and pay for it I want it to be cheap as possible

Condensing boilers are only 95% efficient when return water is under 130° above 86%. Cast boilers return has to be over 130°, glycol has to be made for boiler hot water not automotive. Mixture at least 30% for the inhibitors and only need protection for slush not for freeze. Boiler glycol has both charts. There are piping designs to have a cast boiler and run lower temp for radiate. Primary/secondary loops with three way valves or injection. Cast boilers easier to work on and don't need a condensate drain like a condensing.

I don't have to have it but would be nice. I have a bathroom and it ***** washing hands in cold water lol and yes that is definitely something I want I wouldn't want combustion air from inside the garage

Everyone keeps mentioning the condensing line for high efficiency boiler like it's a big problem? I have plumbing in the room so it's no big deal for me to connect to a drain

It is only a problem if you don't think about it and all of a sudden realize you have condensate to deal with and no drain!

Not a lot of shops have running water and floor drains so dealing with condensate is a big deal.

This condensation fluid should not be underestimated. For a gallon of propane it is almost a gallon of acidic water. Not sure of the ratio for ng.
