just

do a search. You may want to look at a search for legionella Mr Yates has had several posts regarding combo open systems.

Just use the search field, it should only take a few HOURS to look at it all.

Or you can have yor cust come here and post his questions after doing their own search.

They can

E-mail me personally if they want. I have an item or three of interest.

Bottom line; DON'T do an open system, use an oxygen barrier, and I don't have any experience with the Polaris. Don't forget a proper heatloss calculation (not theirs) and don't use 3/4" PEX for the floors in the home (garage is okay).

I'm a homeowner who used them seven years ago and have learned from The Wall 20 times more than they ever showed me...

Others will not be as nice...for many reasons.

Take care, PJO

I have two clients that worked with radiantec before that I could refer to you.

Let's just say I'm unimpressed. And that's straining the limits of my ability to remain civil.

Polarises can be good units, if you know anyone who can work on them. Never put a heat source in your house that no one in your area can service though, and do not install it yourself. The rest of the heating system you may or may not be able to handle; the heat source is a job for a pro. I know, I know, the "pros are just trying to gouge everyone" or whatever nonsense Radiantec spouts these days... remember they are same company that will not educate you about legionella and ignores rampant condensation and mold concerns while acting like their "limited free cooling" is some kind of technological innovation instead of a ticket to premature rot.

On top of that, their parts aren't even cheap. Their SYSTEMS are cheap (not inexpensive... cheap like a beater used car), but their parts aren't.

Ok, well. I guess I said more than just "I'm unimpressed". Let's just say I'm VERY unimpressed.

Second the concerns mentioned above...

Open systems are an invitation for trouble... at the very least, use a flat-plate HX to keep the potable and the heating system water separate.

Radiant heat is not for every house. A closer look at design has to be made to ensure that the house can be evenly heated with radiant heat... big glass fronts will call for supplemental heat, for example. Large sunrooms can really wreak havoc on the controls side since the slab response is so low, etc.

In other words, doing a heatloss calc and suitability study via e-mail is a pipe dream. Installing staple-up systems except in the tightest of houses w/o a secondary backup is an invitation for trouble.

As for the Polaris, they have been used for heating for a while and are a pretty good water heater. Not a substitute for a good boiler though, and keep the water temps high to prevent the ignitors from getting rotted out (condensation). Also, place the Polaris on a 2' high stand so when it requires service, you won't be doing the belly-flop all day.

Actually, I beg to differ. I do heat loads and system analysis via email every day. But like everything else, there is a wide variance in the kind of knowledge and attention to detail different companies/contractors bring to a job.
