Is there a cut and dry pre fab system a guy can purchase? All I need is the heating system being that the in floor heating and wall radiators are already in?  Thanks

ZMAN--If I use a condensing boiler would I have to run higher temp water to the rads or the in-floor heat.  Maybe that is where I confused. Sorry about my ignorance here.

I know this boiler is running at a super low tem.  Output is only 125 degrees. Like I said, I oversized my wall hung rads and only require 125 degree temps to keep everything toasty. Even our 700 sq. ft of in-floor heat that has 3/8 inch pex running thru it is keeping us warm. I want to find a way to keep this temp input of 125 degrees without destroying a boiler in the process. My questoin is (and I know everyone hates water heaters--even Polaris) is weather I should consider a hot water heat system?  I could just run one at 125 degrees and not worry about poisoning us here or destroying a boiler.

Upon reading further on the subject of condensing boilers I have found that the return temperature of heated water after it has run thru radiators and in-floor heating should be 135 degrees or so.  This is even warmer than I currently run thru my system before running thru the rads and in-floor heat. I don't like the idea of super heating water just to cool it down again. If I can only run 125 degree water thru the system to begin with, I see a problem here.

Carl--I can't open the site you sent me.  Any other options available to get me into that site?  Thanks

I was wondering about the temp setting on this boiler also. Guess it's a good idea to get it replaced with a correct functioning boiler soon. I'm surprised it has worked this well for so long. We really cant understand why they put this boiler in the garage when they built a furnace room just for one.  I'll read the information you have sent. Thanks

Boiler does not condense

Boiler was not designed for this temp.  It's an 1998 Crown boiler but plumber  adjusted  it to lowest setting to provide this temp.  Have temperature gauges attached everywhere inline to show temp output. Even the plumber  didn't think it would work properly but this has been working for three years now without problems.

I didn't expect such a quick response to my questions. I've heard installers oversize boilers and furnaces.  Guess it's better to be safe than sorry. I thought condensing boilers needed to condense--thus hotter temp settings were used then cold water was introduced to cause condensing. Is this old school or was I misinformed?

Our current boiler has an output of 96K btu. I like the boiler but not the huge 12 inch flue.  Also there are two huge air intake tubes  that bring in outside air to the garage where this is located.  In the future I want to also heat the garage and want to eliminate all this cold air. Thanks

I did my own heat loss calculations. My schooling was in solar so know a little bit about heat loss. The wood floors we installed only allow 125 degree heat under the installation so that is the temperature we use.  knowing that, we oversized all wall hung radiators for the lower temperature and this works really well also. I am weary about condensing boilers.  I know people that have had problems with these. Guess i'm kinda old school and want a less complicated boiler system that I can understand.  Thanks for your input.

Long winded question here. I'm moving my boiler with indirect domestic hot water tank to new location in my home because the huge flue runs thru the master bedroom closet and she wants it moved. I want a boiler that the flue can exit a side wall and the flue does not need to run above the roof line. Our current system consists of 700 sq. feet of in-floor heat and about 1000 sq. feet of rooms with oversized aluminum wall hung radiators. Everything including domestic hot water uses 125 degree water and works very well. I don't want to heat the water hotter than this just to cool it down again so I need a boiler that I can set at 125 degrees. I want a boiler that modulates but I don't believe a condensing boiler will work because of the low temperature I require. I am considering a closed loop system for heat only but not sure what to use for domestic hot water supply. I am also considering using the current indirect water tank but with newer small flu boiler that will exit side wall as I mentioned earlier. Any suggestions as to makes and models with these specs built in?  Thanks
