Well... I agree.   

In regards to whether it's a sales gimmick, I know empyre would rather not do it because it adds cost and there not making anything off it, we can do a secondary loop like central does or install the factory package on the back. 

But in today's world i to am so skeptical of new things because it seems everyone is out to get ya. Sometimes it's never proven whether we needed the latest gadget or not

Scott, So your saying when my house dumps the cold water back into my boiler theres water dripping in my fire box?..Im assuming you know Hydronic's...

It depends on a lot of variables.....  But when return temps are below 140, you are entering the range at which water can condensate on the walls of your firebox.  I am sure in some cases it may occur at different temps, but generally speaking, when it's returning below 140, your entering the range at which it can potentially occur. 

This is kinda new stuff, as only in the last couple years has companies started talking about it.  Once again I will remind you that it's not an idea to make them money, because the installer can do it themselves and not use one factory part.

for what it is worth here is a quote form "Canadian Plan Service"

quote " Non condensing boilers are the most common. they are called this because the water vapour of combustion is totally exausted with the flue gas. These boilers should not be operated with water jacket temps below 135 F"

[Scott7m]

Yea, that's just a temp range there, it's likely slightly below 140 but companies like some wiggle room

[willieG]

so now with reading the quote from the government source i inserted earlier... scot is right that return temps should not likley fall below 140..so i guess we  can feel relitively safe turning our temps down some in warmer weather if we are so inclined to do so...keeping in mind that maybe the fellow who posted the magic number of 140 knew all along and just wanted to stir the nest of bees a little

now the real experts will come in straighten us out

[jimr]

yes i believe everything our goverment's tell us.

Well I just shut off complete power to my unit.  I have a dual temp gauge in the basement attached to the in coming pex from the furnace and it's reading 88*.  there hasn't been a fire in the box since Monday night.  I see no sense in burning wood just because I can.  There's only two of us in this house and the only thing that would be heated would be the DHW, and I just feel that's a waste of good wood.  So we'll keep it shut down until the cold weather returns again in "maybe" two weeks...I dunno, but I do know what happened up here last April 1...we got cold and we got lots of snow!

I shut mine down too Lug, 9:00 pm here and it is 68*

[martyinmi]

Shut mine down too. Don't know for how long though. My mom said in '64 when my brother was born they had a snow storm and got stuck on the way to the hospital. My little brother very nearly came into this world in the front seat of a '59 Chevy! That was in MAY!! Winter will show up again.

It was still 69* when I came in @ 9:00

[MattyNH]

Still running mine..Yeah it gets warm during the day unlike today..Man It was raw out..At night though the temps still plunge into the 30's..For me its too early to shut it down..Still can get a cold spell with a Nor'Easter off the coast with a dumping of snow..

Shut mine down too     I hope that it doesnt get cold again because    I gave mine a real good cleaning Im still skinny enough I could climb inside and clean the front of the firebox without having to lean over from the outside.    I wish I had the 2400 just for the extra room in the firebox  I think the cresote comes off alot easier actually when it's cold             it comes off in chips rather than like syrup.
