Oil Heat plays the biggest part

@ July 3, 2009 10:07 AM in Anyone seen these WHs?

True, in Micheals case that is when it is turned off and he is running the boiler

Beautiful, and I am not connected to these units in any way. Yes it makes perfect sense that I didn't mention for those that can benefit from dehumidification of the space.

Although that seems like a reasonable question, it also may be a sign of a trouble install with a difficult customer. I'm sure many other professionals have discovered the signs.

ECR (Dunkirk/Utica) marketed those for years with no takers. Maybe it will take now in the future, we will see. Have you seen the add-on units? now those make sense using your own tank that can be changed. http://www.airgenerate.com/

Excellent advice Jack The only other difference that plays apart are those that have the sheet flow or water fall fillers that desire the extra fill rate so that these will work properly.

You may find the supplier that doesn't always have the lowest price may have the inventory.

Bill, I don't think you understand how the retrofit grundfos comfort system works without the return line. Not my favorite choice but plenty of applications http://www.grundfos.com/web/HomeUs.nsf/Webopslag/PAVA-56TMVA

Grundfos comfort pump systems were designed to work that way. Under one or more fixtures you should find a plastic thermostatic bypass manifold piped in the supply lines.

I wouldnt say that's entirely true, even with an EF of .95 on an electric tank, you must factor in piping loss. Those are both factors, but it is the significant reduction of the tankless EF that is firing with no DHW demand, yet maintaining a storage tank, plus circ energy required.

Adding a storage tank to a tankless defeats the purpose and benefits of going tankless.

I used one when they first came out for the simple reason that it had contacts for system pump which I needed besides zone pump relays. Nice unit

@ May 26, 2009 11:40 AM in Trying to Choose a Tankless Heater Brand

Beyond 9 GPM, the unit exceeds over 100' of head, so I doubt the numbers you are sharing unless this is a big circ and the heater will last about 5 days. When using a CC Navien, primary/secondry is in order, and flow through unit shouldnt exceed 5-6 GPM.

Oil companies cut them up all the time to get them out with a sawzall Have lots of absorbant towels for the oil and sludge on hand. Your problem will be getting rid of the remnants and rags.

Right on Mickey Just my dry sense of humor when Dave quipped that it had been said, like the string of comments was to be over.

@ May 17, 2009 11:19 PM in Whats Wrong With These Pictures

Assumptions limit your thinking. Your post is Dave as your name, would you be Dave Lennox?

@ May 17, 2009 10:44 PM in Whats Wrong With These Pictures

My main point was connector rise, beside the welded comment Sorry, didnt realize you and Mickey always gave the final answer-My apologies My store?

@ May 17, 2009 10:20 PM in Whats Wrong With These Pictures

While I agree that square/rectangular breech is common commercially, this install has no rise on the hood, no rise on the horizontal and definitely is not sealed properly given the cloth duct tape. Rectangular breeching is typically heavier gauge metal and welded, certainly not warm air duct.

@ May 12, 2009 9:16 PM in quietside dpw 120 boiler

Rumors are always fun, yet sometimes damaging. While I have no connection with Quietside, I doubt the rumor is true. Being that Quietside is the US operations of Dae Sung Boiler, with boilers made by KITURAMI the only room for growth of the Korean Company is North America, besides some small European markets. With the impending rapid growth of the tankless market, along with the rejuvenation of the combi-boiler market, I would guess they will stick it out. Being that they are one of the 1/2 dozen that has a combi boiler with separated circuits, unlike Rinnai & Noritz that are trying to pass off their water heaters as a full heating solution, internal cross-connection included, the true & safe combi's will find their place.

@ April 22, 2009 11:18 PM in Is Rehau exiting North America

I think Rehau is just focusing- Ground-Air Heat Exchange System From REHAU LEESBURG, Va.— REHAU announces the REHAU ECOAIR™ ground-air heat exchange system, designed for tight building envelopes. In addition to directly reducing the energy required to heat or cool incoming fresh air, the system lowers relative humidity during periods of cooling, and hinders condensation from freezing in heat recovery ventilators (HRV) by raising the outside air temperature before it enters the HRV.

Offended by my humor but noone elses, please accept my earnest apology.

@ April 16, 2009 5:05 PM in What's wrong with these pictures??? (ME)

If you have ever seen a 1.5 million BTU, nat gas direct-fired, air rotation unit sometimes several in one warehouse that are very common, then you will understand my point about freaking over a disconnected flue in a open warehouse, on a 250M? unit. Ever tour a northern manufacturing plant? Then again, maybe thats why so much heating equipment is shipped out with dents, because the dizzy fork truck operators can't see straight? Although I agree if it is meant to be vented, it should.
