Clever Open Sytem

[Deleted User]

when they go on vaction to Dismal World for 2 weeks, the bacteria is guaranteed a place to live, sleep,eat, breath and breed, and then when they come back home on the pay per view germ tube (aeroplane) and have exposed themselves to every airborne disease known to man kind, thereby depressing their immune system, they are virtually GUARANTEED direct exposure to the deadly OMNI-present bacteria, whilst taking their first hot shower after a long hard trip.

Breathe deep...

You're right, that IS a crafty way to kill people. And if I were a lawyer, I could see right through that method of "protection".

So, what happens if the consumer wants more than one zone? Are they SOL :-) If there are numerous parallel circuits, is the flow guaranteed to flow equally through every circuit? Does this work well in a well source system where there is no chemical sanitization going on like in the big city?

I know, you're just the messenger Wayne, it just irks the living crap out of me that these internet peddelars are allowed to push this crap, LEGALLY...

Time for change. Any one care to join me?

Not a big problem, just a stuck circulator, but... it was an open system. (insert evil organ music here.) I got them running but gave them my concerns about the health risks and recommended a flat plate to seperate the potable from the heating system water. The piping, done by the Homeowner, was not very neat, and was little hard to follow, however as happens to me often it made sense the next day as my horse drawn brain caught up with what I had observed. The water feed line did not go to the cold water inlet of the Polaris water heater, but to the hot water line right behind a check valve. This means, that to feed the hot water heater the water has to travel all the way through the radiant floor loop every time someone uses hot water in the house. It still makes me fidget, and I would be more comfortable with a flat plate, but the way it is set up it keeps the water fresh everytime the hot water is used so no bacteria can build up in the radiant floor. Fairly clever I must say. WW

Illegal...

...in these parts. Clever, though, as you say.

We couldn't touch that system here, without risking our license.

Ask me to hook up a system just like that. It was (supposedly) CABO certified. I refused to hook it up because I felt it was unsafe.

Limited Cooling?

Is this the implied limited cooling? But wait, there's more, if you act now, we'll supersize your order to include potential legionella, condensation on your floor with the added bonus of rotted carpet, right when you least expect it, all for a low-low price.....

Nice drawing Wayne. What other drawings have you been witholding from us?

Pandora's box here. You would have to get every AHJ to agree that these systems should not be installed. Even then, how to enforce it? No permits are ever pulled for those installs, so no-one even knows when or where they are going in.

Not sure how you could stop the i-net companies. Heck, the record industry can't even shut down the file sharing sites. They got a few, but for every one they killed 5 more popped up.

I agree 100% Mark. Someone is going to get hurt by these systems, probably already have. Who would connect the dots to the persons heating system or the way they plumbed their water heater?

People have an amazing ability to take a good idea and figure out a way to make it cheaper. Not better, not safer, just cheaper. Consequences be damned and try to prove it in court.

Sad really.

I always enjoy the return trip plane ride the most, bugs and all

It's hard to say how safe even a plain domestic hot water system is (think of large systems and the plans they have in hospitals to keep the bugs at bay), but in this case, the idea of drinking freshly heated water that has first circulated beneath everyone's bare feet does not sound tasty. [I'm going way back to a thread once on the marketing of bare foot radiant floors ...]

Like so many of us here who care more for the cute and furry boilers than for the humans that enslave them, I would think sending freshly chlorinated water down the entire system, pumps, valves, and pipes, is not the best way to ensure system longevity. Chlorination is good for human health but absolutely isn't for machine health.

The separating exchanger or even a separate heater is a cheap premium to pay for extended life service.

Confusingly cleaver.

Sorry to pick nits, but that system remains an ideal bacteria amplifier. Stagnation occurs each time it rests and stagnation is just one thing the bugs require for rampant population explosions. They do just fine in systems that do not stagnate if some of the other suitable environment conditions exist.

Thanks for the replys

Those who know me know I land on the side of closed systems, and have given these folks a price on a flat plate retrofit. I just thought it was kinda interesting.
