@ October 18, 2013 9:26 PM in saving $$... used to be vertical, so there was limited application. Now there is a horizontal unit called Eco Drain http://www.ecodrain.ca/ They will be giving a talk at the ACEEE Hot Water Forum coming up in Atalnta GA. Double wall just is, but units can still reclaim 60% of the otherwise lost heat.
@ October 18, 2013 9:09 PM in budd company/temro automotive eletro-hydronic boiler... http://en.wikipedia.org/wiki/Budd_Company it looks like Budd Company is unlikely to be able to help you. I'd look at the element itself and contact someone like Chromalox http://www.chromalox.com/ to see if they make something that will work. Good chance they made the element in the first place.
@ October 17, 2013 12:34 AM in I'm finishing up the seminar part of our business.Thanks for the warning Dan. I can only guess how much work it is to put on seminars.
So, here's an idea. Why not film the ones coming up and get them on DVD or download so we all can continue to learn? A good film guy and some editing can go a long way!
Now we just need a title.... "The Virtual Dan Series" :~)
ps. Hope you're headed West for a seminar or two.
@ October 11, 2013 11:51 PM in Standard Hot Water TankHello: Questions that come to mind:
1. Do you take tub baths? If so, you'll want a bigger tank.
2. Would the tank live in conditioned space? If so, thicker insulation may not be much benefit.
3. Do you have space cooling? Thicker insulation on tank is then good!
4. More anode in tank means you need to service it less often. T&P should still be checked yearly. Does that servicing frequency matter to you?
Other things: I prefer magnesium anodes over aluminum, mostly for health reasons. All tanks have overheating protection, called a high limit. Shop brand based on how well it's represented nearby. Good warranty service or access to parts is important when the tank goes cold Friday afternoon. Plastic drains are common and easily replaceable.
@ September 28, 2013 1:07 AM in Acronyms... to go nuts! http://www.allacronyms.com/
@ September 28, 2013 12:58 AM in Corroded flange on hot water output side of old crane 100w-150... should be able to build up the flange and then grind it down fairly smooth, so it's workable again.
@ September 25, 2013 7:25 PM in indirect or direct electric resistance... work for the DHW load?
@ September 23, 2013 11:07 PM in 2 Gallon electric water heater.... has an anode in it, there will be gas formed and there doesn't seem to be a way for it to escape. I'd agree with venting at a point where the gas collects.... unless the "quadrature gravity" is at work. :~o
@ September 22, 2013 2:12 PM in bury pex heating lines?...is that you put your well-insulated water lines in conduit. Earth is essentially always wet and is a wonderful heat sink! The moisture, even with insulated lines, will carry off loads of heat. If you keep the lines in conduit, you'll prevent that loss and be able to get to the lines if needed. Others will have to comment on depth of burial and frost line, though if the water flow stops, it must become the same temperature as the surrounding soil in a few hours or less.
@ September 20, 2013 8:55 PM in reasons for 100% glycol... put what you saw wrong in writing and give it to the homeowner. Seems to me you're not doing him any favors by not telling him. Just stick to the facts. It's up to him if or how to respond, but at least he'll know there is a problem.
@ September 20, 2013 8:41 PM in High flow shower heads... add a big shower heat exchanger to make use of some of those BTUs going down the drain. Might be cost effective!
@ September 7, 2013 8:38 PM in Teeny steam generator :-) question... the right approach is to contact Jacuzzi directly to see if they have any troubleshooting guide for this. Here is a link to their contact info .http://www.jacuzzi.com/baths/pages/contact It sounds like there is some water fill problem, but that's pure guesswork. It's likely fixable.
@ August 26, 2013 2:22 AM in wireless domestic hot water circulation... would be demand systems, www.gothotwater.com. They have wireless remote control capability.
@ August 13, 2013 12:49 AM in My granddaughter, Bridget... if a slightly dirty air filter might be reducing airflow, but deciding NOT. I think her first set of tools should be plastic as the outlet is within reach and then the stairs could teach a lesson about gravity. Still, we and many others somehow survived growing up. I suspect diligent parents! Dan, do you think she inherited your inquisitiveness?
@ July 3, 2013 1:39 AM in corrosion on hot water tank inlet... a lot looks wrong here. With melted insulation, drafting is a problem. It is either negative air pressure in the building, pulling heater fumes back, or a partly blocked flue. In either case the poorly sloped vent makes it worse. ~~ I didn't like the look of the vent pipe to draft hood connection. The vent should not be crimped and should go over the draft hood. ~~ I'd rather see lined steel nipples or brass used in the tank, then to flex connectors, rather than copper pipe directly to the heater. This would help prevent galvanic corrosion. ~~ The water might be condensation or it could be a leak. You might want to uncover the pipes and mop up any water to see if you can find where it comes from.
@ June 30, 2013 11:57 AM in asphalt laminated kraft paper and staple up radiant floor heat... you can hook up an electric water heater to the tubing in a room and heat it up? That would give you an answer pretty fast.
@ June 16, 2013 2:06 AM in Plumbing Forum?Hello: It sounds like water is leaking from hot to the cold side of the plumbing, but testing for it will give you some more info to work with and help in the fixing of it.
To test for cross connection, turn off water to your water heater. If it's electric, turn off power, if gas turn to pilot. Open a hot tap somewhere other than the shower and see what it does. If there is no cross connection, the water will run only a little, then stop. Otherwise it'll keep running. If it runs, go back to the shower and listen for a high pitched ssissing sound. Let it run a few minutes. Stop the test , put things back as they were and then run hot water at the shower. If the valve is cold and runs cold for a while first, you know that cold water came from testing and that there is a cross connection at the shower valve.
From there it's valve seats and/or washers/seals that are leaking.
ps. 100 psi is too much. 40-60 is considered normal and is easier on the plumbing.
@ May 8, 2013 12:21 AM in Copper pipe pittingHello: Thr Copper Development Association has done loads of research on pitting corrosion. Here is a link to over 600 papers on it.
@ April 6, 2013 11:05 PM in More efficient water heater.... water heater from Australia that captures waste heat from grey water. Called Nexus, it doesn't have the potential downside of chilling water that will need to go for bathing. It's still a new idea, but has potential. Here's a link. http://www.riftwood.com/texus/technology/
@ March 2, 2013 7:26 PM in Gas light parts... is the last maker of gas lights I know of. I'm pretty sure they are still in business.
@ March 2, 2013 7:17 PM in John wood h20 heater leak... are Water Pressure, (make sure there is no pressure spike caused by thermal expansion, or just plain high pressure)
Conductive Water usually caused by over-softening, (makes the anode rod get used up way too fast),
Quick Closing Valves can cause damaging water hammer,
High Water Use can put the heater in condensing mode so much that it rusts out from the fire side (get bigger heater).
I'm curious to know where the heater leaked. Overhead plumbing leaks are tough on heaters too!
@ February 16, 2013 2:08 AM in What business lessons did you learn from the Great Recession?1. History does repeat itself. The stuff my grandparents learned in the Great Depression fits nicely now.
2. Trust your community. This is a community. If you don't have much of a local one, think about how to make it happen, because there is more security there than in any gubermit program.
3. Live below your means. It's an interesting challenge to see how low you can go.
That's my three!
