... long lengths of insulated PEX by using PVC conduit and pulling the insulated tube through the conduit.  I don't know how it compares price-wise, but it works.  Just make sure the conduit ID is enough bigger than the OD of the insulation so there is good working room and low friction.

... water heater.  I'm not so sure the plumber's tape will do much, but as the heater is probably around 80 years old and hasn't fallen over yet in earthquake country, it might not be a big deal.  Suppose that even though it's cast iron, it's a low mass heater.  I know... it's held up by the gas line!

... to find someone with a Duct Blaster.  http://www.energyconservatory.com/products/duct-blaster%C2%AE-systems-and-accessories  This is a diagnostic tool that will measure duct leakage.  The AVERAGE leakage is 30%!   Once you have snug ducts, all heating will work better.  I like the idea of using fan only to mix up air in the house.  Putting a return air grill high up in the room that has the stove might help pick up some of that heat to distribute.

I can only answer...

@ February 6, 2014 1:54 AM in On-Demand Hot Water Not Working as Expected

... part of the question.  No hot water at the kitchen might be a plumbing problem rather than an equipment problem.  Try this test for cross connection:  Shut off water supply to the hot side of things.  Then open a hot tap.  It should run for a second or four and then slow and stop.  If it keeps running, cold water is making it's way into the hot side.  Your job is to find the leak and fix it.  It is most likely in fixtures that have a single handle.

question

@ February 5, 2014 12:19 AM in Debris in our radiant heat system

Hello:  What is the heat source for the system?  Is it a boiler, or a water heater?

Yours,  Larry

Reading between the lines...

@ February 1, 2014 3:45 PM in Heating solutions for naughty children?

... Are your kids putting something in the heating duct that shouldn't go there?  Something smelly?  If that's the concern, can you move the register up on the wall or into the ceiling? 

I might have the system checked for duct leakage as the average is a loss of 30%!

Yours,  Larry

You're right!

@ February 1, 2014 1:21 PM in A new show

It's dry.  In Monterey, where I am, we got about 4.5" last year.  Normal is around 15".  Snow-pack is at 12% of normal and reservoirs are around 10-30% of normal.  

Coming up next week is a show on water and creative ways of using less ... finding more.  The talk of earth closets should be fun!  :~)

@ January 28, 2014 12:01 AM in How long in the shower?

... measure flow from the showerhead.  Run it till it just begins to cool.  Calculate the gallons.  It should be about 70-75% of the volume of the tank.  If not, check the dip tube.  With colder groundwater this time of year, there just will be less hot water unless you turn up the temperature.

Also, it's not hard to find decent 1.5 gpm showerheads.  At 30 gallons and a 60/40 (hot/cold) mix, that would be about 33 minutes of shower. (if my math works) :~p

@ January 13, 2014 5:33 PM in New Hot Water Heater

... following this statement "...there won't be any flame in your empty tank after flushing, you run the risk of the thing not igniting".  You can turn the gas to pilot rather than off when you replace the anode.  Even if the gas is turned off, you relight it.  No big deal.

Muddy waters

@ January 13, 2014 5:12 PM in 80 gallon elect on night meter..? power vent gas ?

Just to muddy the waters a bit, depending on price of gas and electricity, a heat pump unit with a COP of about two might cost you roughly the same as gas to operate.  There might be incentives for it as well.  Check out http://www.dsireusa.org/ for info.

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.

If you do this...

@ December 13, 2013 3:03 PM in Water softener for hot only??

... 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. ..

@ December 11, 2013 8:32 PM in New install: choose propane or oil?

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...
