Bad chlorides!

@ October 17, 2010 11:36 PM in Navien Heat Exchanger Problems

Chlorides are bad, seen it cause all major brands of stainless steel indirect water tanks to fail. On that note, I doubt eternal has anything better than the rest, especially at the water tube welds.

Nope

A Taco 010 circulator doesnt have a chance when applied as a open system. It maxs out @ 10' head
Why does oil matter?.

word of advise Chris

@ October 17, 2010 5:51 PM in Heat loss calculations. who does em?

If you do the work for the contractor, they never learn and will become to expect your free service all the time and quickly. How do you expect to do 20-30 a week someday?
You will burn out and and only anger your customer

I bet

@ October 11, 2010 2:26 PM in CPVC / PVC - boilers

Chris, the company that you work for sells numerous condensing appliance lines, including boilers that use PVC, so I find that hard to believe.

What about the HTP Munckin line listed on your  product card?

ULC-S636

@ October 11, 2010 11:09 AM in CPVC / PVC - boilers

No one here thinks that ULC-S636 PVC pipe and fittings is special right? because its not.
It is the same Sch 40 PVC, solid core pipe meeting ASTM (Plumbing) standards in the US.
In the summer of 2006 the CSA B149.1 Natural Gas and Propane Installation Code was amended to require all plastic venting materials to be certified to ULC S636. The code change is effective January 1, 2007. Provincial regulators from across Canada changed the B149.1 Code to make certain that all plastic vent systems are certified to a recognized standard.
It is still 65 degree C or 149 degree Fahrenheit.
That required rating label and orange sticker elevated the cost 4X the sister pipe for plumbing made on the same production line and out of the same stock. About the only thing they accomplished was to keep the clueless and cheap contractors from using foam-core or cheap import pipe and fittings, improper glue, ........
As with the earlier plexvent days, it wasn't really the product but the install, improper fittings, lack of support, improper assembly that caused the failures.
I can understand a distributor person passionately taking a stand against the use of PVC for venting, when they are attempting to compete with product that doesn't allow it. In the end they are attempting to justify the $300-$900 system cost difference of their product install.
We have vented furnaces, boilers and water heaters for 20 + years that way, (boilers being shorter) it will be a battle boiler manufacturers that have fought but have adapted and changed to in order to gain product acceptance and market share. You can argue that the European market doesn't use PVC venting, yet they also don't use it for plumbing either, so have no easy access.

Misinformation

@ October 10, 2010 1:24 PM in CPVC / PVC - boilers

Both Burnham models, the Alpine and Freedom allow PVC/CPVC

Oh really

@ October 9, 2010 10:40 PM in Buderus

PVC has been used as a venting material on furnaces since 1983, water heaters since 1986, overseas doesn't use PVC for plumbing so not available, ASTM only applies to plumbing, so ban it for venting? Not likely

You sound like a distributor or rep that has no product that vents with PVC

Pay attention

@ October 9, 2010 10:36 PM in Integrated HVAC

Your confused heating box is an actual product with no burner inside

Go to manufactuer

@ October 9, 2010 9:51 PM in QVM 9-090W1-NG PARTS SEARCH

That's a Quietside right?
Go right to the manufacturer importer in california, they are in a name change stage, going to company named CoAire.

Good luck but older quietside units have no available parts.

Silly rumors

@ October 9, 2010 5:58 PM in Navien in trouble with the DOE

You are wrong Chris
You see they are tested and hold certification from the largest most respected  independent testing agency thus carry the CSA, CSSA stamp, that has certified combustion, thermal efficiency, along with Energy factor.
You remember when Energy Star got caught listing items such as a gasoline powered alarm clock?
That embarrassment, caused DOE to do some auditing, who partnered along with EPA with Energy Star. Can you blame Navien America, Inc., if the DOE sent the request for duplicate paperwork to Korea Navien?

FYI, Navien wasn't alone, there were about 15 companies involved at same time, most with similar reason. Most I hear with proof have had fines dropped or excused but who cares, once again a government agency has inflicted the damage.
Thus you Chris being a fairly new inside sales guy for a distributor or a rep agency, handing out this info without full info only serves as tool for your future embarrasment for lack of being fully informed.

IBR

IBR is a standardized calc allowing for piping loss getting the heat to the conditioned space

More to it?

@ September 20, 2010 9:25 AM in Disadvantages to oversizing in-floor tubing?

You wont suffer with larger tube unless you must pay more for the tube and accessories.
The downfall would be if he wants to increase spacing because of increased output capabilities but would suffer on comfort.

Old Stock

@ August 31, 2010 9:37 AM in Grundfos isolation flanges

If you came across the screwdriver slot flange sets, they are old stock.
Once Webstone and many others introduced isolation flanges kits, some with checks, the ones from Grundfos introduced back in the '80's became obsolete. They were 3X the price and contractors preferred handles.

This is no big deal, they just make this up as they go along.
Heres another one:

Since so many foreign manufactures are under the World trade Organization Procurement Agreement, (WTO GPA) which is part of the ARRA 2009, almost all products would comply except from a few countries.

What pump?

@ August 18, 2010 5:49 PM in Navien Heat Exchanger Failure

Explain why the 240ANG would have an external pump when the pump in the heat box creates the flow through the Navien unit to make it fire?
There should be no extra pump or circ between the heat box/Navien connections
Did you add one (not shown in instructions) and by doing so double stack the units resulting in excessive head and flow?

Well..

Does the lowest market price and lightest equipment weight of comparable Tankless mean anything?

Almost

@ August 15, 2010 11:36 PM in outdoor reset.

With steam you cant reset water temp, it wont boil.
There are controls to change cycle times or control valves though.

whoa

@ August 15, 2010 11:31 PM in Sizing Secondary Pump for Replacement Boiler

Are you sure its a true series system? Thats a bad design for CI rads and would be rare.
I seriously doubt the PS110 boiler pump could handle the split, multi tap radiation system that required a HV circ previously
You better get one sized for you, I would help but so much more info is required
Tanks are sized on BTU and SYSTEM VOLUME, guessing the tank size isnt a smart move, but a # 30 would be a good guess.
