Honeywell / Plus 40

David Sutton_6

I talked to them again today and they said that it was after they put the 2nd tank in that they put the presure reducing valve on, they seem to think that they over presurized the water tank and reduced the the volume of boiler water capible of hreating the tank.

Call me if you can at 413-569-2345

Two differanent problems

#1.. got the info


#2..A W+M Plus-40, runs stone cold after about 6-8 mins, the boiler water is circulating thru at boiler temp but there is no heat transfer, the dip tube as checked , they added a presure reducing valve,. Then they changed the tank and it still dose it, its 3/4 pipe and a taco 007,i have not looked at the job yet and this is all the info i have right now.

Gold Plus...

David,

Couple of things...

The W/M Gold Plus has it's own T-Stat on the unit...It's where the dial is for temperature control...You do not need a extra limit control...

Second...Which boiler is the W/M Gold Plus hooked to..???

Jim Farrell

Gold Plus...

David,

Also how far is the supply and return pipes...????
The W/M Plus Tank must be piped with 1" pipe not 3/4"...Check out the install manual...

Gold Plus...

David,

Also...Check where you have the supply and return connections...Supply and return are different on the gold plus...

Supply is on the bottom tapping and the return is in the top tapping...If this is reversed then you will have hot water delivery problems....

Hello Jim

This i know, on a cold start application you need to triger the boiler to come on, on the new control theres no ZR to call on the boiler in this mannor, that i am aware of.

as far as the piping goes i'm not sure have not seen the job
but this was working fine for a few years then stopped, and the tank was swapped out with a new tank and still the problem remains, i will see if i can go look at it.

never mind

I goofed on my Plus 30

and have the boiler in and out reversed . We haven't run out of hot water yet . I wonder if anyone has info on the decrese in recovery if the piping is reversed ?

Phase III

I have done it several, according to their rep the difference is minor- I don't think you will notice it.

2%...

at least on a flat plate HXer...

On a tank within a tank, I seriously doubt you're getting much consequence out of it.

Piping

Reversing the piping on the Smart or TR tanks boiler side has almost no effect on output because the boiler water passes around the tank very quickly and easily due to the low head loss through the outer tank.

Mixing Valve

See if there is a mixing valve on the tank. If so, pull the guts out of it and see if there is anything in there. I recently had a similar call in CT, and there was a foreign, waxy paper like substance in the MV, causing very erratic operation. I checked the replacement to see if it was some sort of packing material (like we all left in a flow check early on--admit it!), but there was nothing in the new one. I haven't heard anything since the fix, so I assume that showers are hot enough.

Hello Guy

Thank you for your responce!
I installed the tank about 7 or so years ago while i was at the company, its worked fine since, then all of a sudden they have this problem, the man working on it was my partner on the instalation team at the company and is very good at what he dose. so i belive all bases where checked. i talked to him yesterday and asked if he could get me in there.
Got 3/4 pipe to and from boiler 1/2 pipe hot and cold
dip tube checked , presure valve install ,50# presure now was almost 80, this is in Enfield CT.

Do you have an Thermal Expansion Tank on it...???

If so did you tank it off and check the PSI of the thermal expansion tank...??

pressure

The pressure in the tank should have no real effect on the recovery. The problem is the transfer of heat from the boiler to the tank. Where the tank has been replaced, we can safely rule that out. The problem HAS to lie in the delivery-Pump, relay, check valves, boiler temp or boiler's ability to make heat.

The 3/4 lines aren't helping things, but even the diminished recovery should be better than you have described.

reverse

You did yourself a favor. My experience shows that the "lag" of the tstat is less noticeable with the boiler S&R reversed. Siggy's writings back this up. Most of the 30's I've installed "by the book" ended up with mixing valves to counter the temp swing.
