Meddling here.

@ January 11, 2014 11:14 PM in New Hot Water Heater

You might want to consider having a look at the existing anode rod in the tank and seeing if it has any life left.  If so, the tank (with a new anode) can probably give you many more years of service.  Getting 30 years is easy.

Yours,  Larry

My first idea...

@ January 3, 2014 3:21 PM in Marathom waterheater pros and cons

... would be to replace the anode in your current tank and try to keep it going, but then I'm an optimist.  Next would be to look into a heat pump unit with bigger (80 gal) tank.  This could be run only during off peak hours and generate some energy savings.  Set it to run only in heat pump mode for more savings.  These units do make noise and they need good air flow.  They have a filter that must be cleaned to keep that good air flow, otherwise performance can really drop off.  There may be some $ incentives to go with a heat pump also.

Marathon is nice, but is only one option.

Yours,  Larry

Matt, nice...

... then be sure to check the anode in your tank more often.  I'd check it when you add softening and again in six months to see how fast the anode is being used up.

Yours,  Larry

Have you considered. ..

things to check

@ November 23, 2013 8:08 PM in Vaughn Water Heater

Hello:  Yes, your heater is old, but if it's set up now so a leak won't cause damage to floors, walls or stuff, then keep the unit going.  I'd have a look at the elements, thermostats, dip tube and relief valve.  Your problem of reduced hot water are most likely a damaged dip tube or burned out lower element. 

Do check or replace the relief valve.  A heater blowing up will just ruin your day.

Yours,  Larry

if the pressure fluctuations...

@ October 28, 2013 12:53 AM in Need help with water service noise / banging....

... are caused by the water supplier, then they are likely having a pumping problem and need to know about it.  I had a problem where the house pressure fell to less than zero every 55 minutes, but only for a second.  The nearby pumping station controls were messed up and the water utility didn't know.  A recording pressure gauge might be useful. 

Yours,  Larry

Have a look...

@ 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  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.

...  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 to see if they make something that will work. Good chance they made the element in the first place. 

Yours,  Larry

Fair Warning

@ 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"   :~)

Yours,  Larry
ps.  Hope you're headed West for a seminar or two.


@ October 11, 2013 11:51 PM in Standard Hot Water Tank

Hello:  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.

Yours,  Larry

If that water heater...

@ 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

Yours,  Larry

A suggestion slightly off topic...

@ September 22, 2013 2:12 PM in bury pex heating lines? 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.

Yours,  Larry

I think I'd ...

@ 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.

Yours,  Larry

One might want to...

@ 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!

Yours,  Larry


@ 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  .   It sounds like there is some water fill problem, but that's pure guesswork.  It's likely fixable.

Yours,  Larry

a good first place to look...

She seems to be wondering...

@ 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? 

Yours,  Larry
