Did a lot of searching without a good answer - maybe you guys can help! I'm putting together a new heating system for the house, based on a Trinity boiler with seperate loops for house heat and an indirect water heater. I've assembled the boiler, circulators, relief valves, fill valve, etc...

My new NTI Trinity boiler specifies CPVC for vent and air intake when the boiler is located in a closet, and also specifies the use of PVC to CPVC transition cement. Who makes this cement? I haven't found any!

Since you sparked my curiosity, I looked at Hydronic Alternatives. Did you check their installation guide at http://www.hydronicalternatives.com/RadiantPanelInstallationGuide2006-10.pdf? That has all the info you'd need. Interesting system!

I'm putting my new HVAC system in the garage: a Trinity boiler, B-W indirect water heater, and Goodman variable-speed counterflow air handler with hydronic coil and evap. They'll be located on the wall between the house and garage on a platform raised to the level of the house. The supply duct...

Larry, I'm far from expert, but I've been working with a company to spec out a new system for my house. Here's what we're doing: A single high-efficiency modulating tankless boiler (Trinity) feeds two closed-loops. One goes to an indirect water heater (hot water coil inside a conventional...

Sincraft, you may have misunderstood what I was asking the salesman. All I was asking for was a single PRICE for HARDWARE! Is that taking too much of his time? The reality is, this company does not like homeowners, and only deals with installers. It's a free country, they have that...

Being an engineer doesn't make me good or bad. Being a licensed tech doesn't make an installer good or bad. In both cases, it's the attitude and pride in workmanship. The tech has the experience, fer sure! But he can use that experience to make a better installation, or to finish the job...

My searches have led me to several different high efficiency boilers/heaters, for use in a combo system. From the advertising, each is the answer to all the world's problems, of course. But only in a forum like this one am I likely to find people who have good or bad experience with them...

Thanks again dudes (and dudettes). If I've accomplished nothing else, I've certainly opened up quite a discussion! Never expected so many replies. That's a good reflection on the people who use this board. Perhaps I'm an atypical engineer, one who would much rather have his hands dirty...

Ok, I've cooled down now. Thanks all. I think you've been very realistic for the most part. I'll defend myself on the arrogance point: The snobbish salesman didn't know about my education. I don't believe I was being arrogant. I didn't expect to be "bowed down to". But I believe...

Is there an HVAC distributor out there who will talk to the homeowner? Since two contractors have given me grossly over-priced bids on a new HVAC system, and are slow in working up scaled-down versions, I started reseaching what's out there myself. I now have a fair idea of what I want. I...

Thanks guys. I had a rather dim suspicion it might be a temperature limit circuit. I agree 500% about disabling safety features - that's why I came to this forum. As a Navy employee, I often read an aviation safety pub that occasionally hits on such things. I'll try to contact B-W, but...

My B-W propane water heater, about 22 years old, has gone through several thermocouples in the last few years. The techs installed a new pilot burner and tc recently and all was well till we came home from vacation Sunday night and found we had no hot water. I tried to relight, but it wouldn't...
