smart 40 and 50....i just installed 2 ....im used to installing the Crown megastor indirect....how is the tank for the smart 40 and 50's drained? lets say i have to replace one there is no tank drain. thanks Paul S

Robert O'Brien

Pump them out

Paul S_3

thanks guys...

If you pipe them right, you can just siphon it. I think the manual shows it clearly. You should also use care in filling it. You must fill the DHW center before the heating side .

SWEI

Don't forget to depressurize the outer tank before you drain the inner tank.

I've drilled a hole in the inner hx thru the lower boiler tap out of desperation when my pony pump died on site. Fun.

Zman

Hmm.
If you pipe it like page 8 in the manual http://s3.supplyhouse.com/manuals/1297270212205/47060_PROD_FILE.pdf

Draining it is pretty easy. You hook a hose to the drain and open the drain with the supply still turned on. Once the water is flowing, you isolate the tank from the supply and house and crack the T&P. 20 minutes later, the tank is empty. It just siphons out.

I guess if some piped it incorrectly, or if you did not have a floor drain, you would need a pump or a hole or something.....

Zman

True enough Hatt. This is a problem with the design. If you can run the hose outside or to a lower floor, you can get more of it.
Since the tube does not go all the way to the bottom of the tank, even the pump does not get it all.

This is how I empty TT water heaters, you never get the last couple gallons

thats what i didnt do pipe a drain valve to the floor....ill do that once i start the boilers up when construction is complete....why wouldnt they just make it easy like the crown megastor's that im used to installing.....if i remember correctly some of the weil mclains are similar...this is how i drained the last weil mclain 119 gallon...thank god there was a floor drain....i guess i wasnt thinking.lol

SWEI

The inner tank is suspended from the top in order to allow it to expand and contract. This prevents a conventional drain valve (at the bottom of the tank) from being fitted.

Pretty wimpy connection to make it from the line to the install. That would be a nightmare for the tech department. Maybe something of the sort of kit that could be installed after installation. Once rough handling is done.

Bob Bona_4

Always liked the tank in tank concept, massive heating surface area, resistance to liming up. But draining, always a PIA.

Bob Bona_4

Right. Then do whatever it takes

Solid_Fuel_Man

Or shoot it with a suitable um....device. .22, nail gun, Ramset etc.

More fun and louder!
If we are talking do whatya gotta do.
Bystanders beware.

After frustration a clip of .45s Would make for a quick draining. Uncontrolled but quick.

BobC

Five shot pump riot gun would be more fun.

Harvey Ramer

With breeching loads.

Bob Bona_4

.50 cal belt fed is what I want for some of the stuff I work on!

Gordy

That would be fun explaining to the HO this is normal procedure.

Bob Bona_4

That's when you need them to go up to turn up the thermostat.

Solid_Fuel_Man

If one has not had the experience of fireing a belt fed weapon I would highly recommend of for said TT indirect
