yea only problem its extremely rough math, because need to find the Feet of Pipe from boiler to farthest heating device. only two ways they coulda done it, but anyway. im sure it will be fine. If washing machine on, everyone used to not taking shower. Plus the city cant pump the water any...

i found out via https://www.manualslib.com/manual/834596/Nti-Trinity-Tx51.html?page=7#manual says "In US/Canada, PVC vent pipe and fittings shall not be used within the closet or alcove; only approved CPVC, Polypropylene or Stainless Steel vent pipe and fittings can be used" also page 16...

ty i just found out via manual, boiler shouldnt be next to laundry, detergents cause damage. My washing machine is 5 feet away in same room. i dont suppose its bad for todays boilers. its been this way for at least 30 years, with old cast iron gas boiler.

wait it was hard sometimes understand, painful ahh? so far, i only know as much a real estate agent, maybe less . Ive gotten alot of bad deals, im sure whatever i get now, will be better. Feel like i understand these boilers better, what to look for. and i thank this forum for that and you...

i figured out the water load nvm, double post* http://contractingbusiness.com/residential-hvac/how-calculate-water-system-btu-measurements

Thanks so much, its just one more concern, because last contractor mentioned the pipe to chimney was too small but its just duct work airing out whatever rubbish to the chimney. Also that only combi could be installed. is there such a thing? wouldnt any boiler work? right now, i have a draft...

the only thing i know is how to calculate edr, mine is 175. with 6 cast iron radiators i just about had it researching this stuff, way too complicated. Now im not even sure if my radiators use water or steam. but if i turn the knob at the top, its a small skinny top, it leaks water when its...

oh now i see why i shouldnt get condenser. if you have any recommendations, please let me know. and what about modulation, that would still deliver precise btu? if i ended up installing condenser boiler, it would still work with water based radiator? of course still short cycle right?

Hi Dana, ive still been looking for good deal, please let me know if this wont short cycle ive decided to try a combination boiler that modulates, I cant tell if this offer is honest i was offered an ibc boiler. Since it modulates between 20000- 125000 BTU Does that mean, if i need 30,000, it...

Wow, im suprised my boiler lasted this long. Its 100k and 80k depending if using different gas. shouldnt it have stopped running by now? i assume it would have short cycled to the scrapyard already. i dont know if i should have read the article better, that makes perfect sense, Could i...

i had some contractor visits, not pleased with what was offered. i keep getting 80k-100k btu offer. i dont know what to do. i sized all radiators already. total btu required was roughly 30k. I had one lowered to 50k after i explained to the contractor about sizing radiators. anyway, could...

Nice so my math is right. I didnt always sit in the front of my math class, but sometimes i got an A. Well the sections are 7 " wide. Will that change the formula up? i dont think need that much precise for btu? but i have coordinates via google earth. they are within my neighbourhood. Id...

ty, its definitely 2 column. I measured one radiator just now please tell me if the math is right. Height is 32". Should i also add height from the four legs? anyway heres the math, 32" in 2 column = 3.33 * 6 sections = 19.98 EDR ? Also i found out how much energy used, hope its not a...

sorry couldnt get back on forums was busy this week, i totally forgot. But anyway, i tried what you said. Could i get help to check if my edr calculations are right? for example, my house roughly 1000 square feet. Basement has no radiator though, so id try 700 sq feet radiator is hot water...

Thankyou, Lars sound good then, I have their boiler, its mighty old though. Around 31 years, could be older, because I only have a hvac note printed "1985" by a local contractor who either cleaned it or installed it, doesnt say which. The heat exchanger is rusty this year. I have it cleaned...

lol i live in Canada, Ontario. Winter is very bad sometimes, -20. My boiler uses a gsw water heater storage tank, rated 35000 btu-hr, has the duct work. If i could buy the Abrams, i still wouldnt pay them 14k for the Bosch setup. Thats what my heat supplier offered, or a slant fin for 10k after...

i dont want to take op post attention, but my house is an old roughly 1000 sq. winter gets really bad. Someone mentioned electrical boiler can work. This hvac guy from home depot recommended navien with 80-100 BTU with my tank. is it overkill?
