@ February 6, 2008 3:14 AM in The next generation of mod con burners will

ah. so it, like the one kind lady, will have the opportunity to completely stop its cycling?

i have some understanding of modulating boilers - what does a 10:1 turndown mean?

@ February 4, 2008 9:31 PM in Burning Salt Water?

they have never reported a net gain, just a large fraction as the return.

right i read about that... radio waves though. not radiation. thank goodness.

@ February 4, 2008 1:23 AM in Copper Pipes / Steam Heat

woa woa woa... you have copper-fin baseboards mixed in with a cast iron steam system? thats not a good sign for the install. with a couple of pictures these guys could tell you quite a bit.

paul thanks, that was extremely helpful

@ February 2, 2008 4:28 PM in Taco ZVC404 to Tekmar 508's

So I'm trying out some tekmar products - and I initially just wired up some temporary power to the taco zone valve control, hooked up one zone valve and one thermostat (of several) to see the display on the stat: nothing happened. I cant get even a blip of life out of these thermostats. The ZVC LED indicates the circuit is complete, light stays on... still nothing out of the stat. I wired the zone valve just to see (Taco EBV) and it was powered and fine. I tried all of the stats (new out of box) and rewired it twice. I just don't get it! 120V --14ga--> 24V transformer (ZVC404) ----> Zone 1 TT terminal(ZVC404) --18ga--> C & R terminals (Tek508)

... i don't see any gas shutoff at all?

They're here. takes a while for a post to show up when you type it with two fingers.

@ January 30, 2008 6:41 PM in Radiator under a window seat?

actually... i had the same question myself once, so i put a few scraps of ply and 1x on top of some steam radiators, just layed on top. some of the ply delaminated and warped pretty seriously. the solid wood did fine. edit: i'm sure some thin solid ins. would be enough.

salt and mineral content?

@ January 19, 2008 9:30 PM in Absolute Zero

it was a great program. i didn't know the carrier name went back so far.

@ December 21, 2007 7:04 PM in Anyone seen this before

i have a bunch of them in my attic... not such a nice lead strap though

@ December 14, 2007 1:52 AM in Parts Supplier--Pex Supply?

they don't stock much. usually, as in almost always, takes a week before they ship.

blue block has that lovely iodine taste... some can't resist

@ December 8, 2007 4:25 PM in boiler gone wrong

but who would be willing (or generous enough) to ruin all this good stuff just to give us a laugh? clearly the system has been actually running some.

@ December 8, 2007 2:01 PM in Primary/Secondary quick question

thanks guys i have cast iron radiators, of a medium size, i shrank them all by 50% when i rebuilt the house and insulated it. i'm coming to the end of year two - and this heat will be the icing on the cake. i'm going to go with p/s i see! if the mass is great, the boiler temps are low for some time and that itself can cause condensing. i thought it was the DIFFERENTIAL between the supply temp and the return that made condensation. but no thats where thermal shock is the risk! i see i see. its the low temperature itself. ah ha! all i have to do is balance the isolation valves to ensure some bypass in the primary loop at all times - even in an all-zone call situation. i'll be back with some pictures in a few weeks. many thanks

@ December 8, 2007 1:48 PM in red and blue pipes

it's pex, and its good for that use

@ December 8, 2007 7:23 AM in Primary/Secondary quick question

1" supply/return, 50k output cast iron (WM cga3) boiler. taco 404 zvc w/ outdoor reset & 4 zones. i did a heat loss and my maximum possible temp. drop (allzones) is 11.25 degrees. would it be worthwhile by any means to do P/S pumping on this circuit? the zones can easily do 8gpm max, which matches what the 1" supply can manage in the primary loop. so it would not be infrequent that the primary loop would get taken up entirely into the circuit. with such a modest delta T (11.25) is the outdoor reset enough protection? note: the slowest flow across the boiler with only one ZV open would be 4 gpm.

reminds me of that old ditty

@ December 8, 2007 1:20 AM in For those who burn wood............

Beechwood fires are bright and clear If the logs are kept a year Chestnut only good they say If for long it's laid away Make a fire of elder tree Death within your house will be But ash new or ash old Is fit for a Queen with a crown of gold Birch and Fir logs burn too fast Blaze up bright and do not last It is by the Irish said Hawthorn bakes the sweetest bread Elmwood burns like churchyard mould Even the very flames are cold But ash green or ash brown Is fit for a Queen with a golden crown Poplar gives a bitter smoke Fills your eyes and makes you choke Apple wood will scent your room With an incense-like perfume Oaken logs, if dry and old Keep away the winters cold But ash wet or ash dry A king shall warm his slippers by. (elder tree is larchwood types - they send sparks)

@ December 8, 2007 1:15 AM in boiler gone wrong

ha ha ha! this is a good point to start a 'wall of shame'

@ December 7, 2007 4:56 AM in can ODR make TV a barrier?

Could a TV like the Danfoss esbe block flow in a primary loop if an outdoor reset is added? I'm imagining a day where supply temps go under 150... while the TV is set to open at 160.
