heating guy

@ March 1, 2014 9:01 PM in Boiler not turning on

should be able to fix it.
BUT if it does it again try tapping gently on the vent damper first. then tap on each component - you may just find out here the problem lies.

white coating

@ March 1, 2014 8:53 PM in How concerned should I be about this TT error?

Having a white coating of the flame rod or igniter usually means that you have exhaust gas reversion.

elements

@ February 22, 2014 11:06 AM in elements burning out prematurely

When you say burning out - are they melted looking or just won't heat up?
If they are melted then I would say you are somehow running them dry.
If they are just not heating up then check to make sure that you have the right element for the voltage you have.

Munchkin

@ February 18, 2014 10:38 PM in Munchkin Boiler Problem

When is the last time it was cleaned. On propane boilers using a gianoni  (spelling) heat exchanger they need to be cleaned yearly.
constant F09 codes means the boiler either didn't fire or didn't prove ignition.
There are many things that can cause the F09 code. Dirty flame rod, plugged drain, burner gasket gone, improper combustion settings and recirculation of exhaust gasses.
IF all of these are not a problem then changing to the newer 926 control kit will solve MOST of your F09 problems.

power vented

@ February 6, 2014 10:56 PM in Flue liner size for new gas water heater ?

Just because the water heater is vented in PVC pipe does not mean it is higher efficient than a standard natural draft heater.
The power vented model uses electric where the natural draft doesn't.
The power vented model uses a LOT more house air ( heated by furnace ) to dilute the exhaust gasses of the water heater to lower the temperature down to the point that it can be safely vented out the PVC pipe.
So in reality the power vented model is probably much less efficient after all of the other factors are included.
OH one other thing - If the power goes out the natural draft model will still give you a hot shower as long as you don't have a well.

piping

@ January 29, 2014 9:57 PM in Closely Spaced Tees - maybe not?

It isn't piped properly BUT I don't have a real problem with it. the ruturn piping should have gone straight to the supply main with two tee's spaced about 1/2 inch apart. The boiler then connects to those tee's. Is there a pump to the right of that picture? OR are there multiple pumps off to the right?

indirect

@ January 26, 2014 9:30 PM in does this system look right?

I can't blow up the diagram - I thought the piping going off to the left on the diagram had Initials for domestic hot water. AKA - indirect.
BOY - I am batting zero today.
Sorry

I would have piped the chilled water primary / secondary also. But the tee's for the chilled water would have been after the boiler tee's - less cold water induced into the boiler loop even with the spring checks.

@ January 26, 2014 7:54 PM in does this system look right?

Boiler plate is a term I heard years ago. It is just a piping template.
Roll a troll has the piping connections going into the side of the tank at an angle to induce a spiral flow inside the tank.
I didn't look long enough at the pictures. I see that the tank doesn't have 4 tapping's
I looked mainly at the diagram.
If that is a roll a troll or equal then the piping still isn't right.. Then the boiler loop needs to be piped primary / secondary with closely spaced tee's - not spread apart like in the diagram. And the indirect still needs to come off of the boiler supply pipe before it goes to the main.

@ January 26, 2014 5:55 PM in does this system look right?

IF the system is piped like your diagram then it IS piped wrong.
First why have a hydraulic separator and not use it. The boilers need to be piped directly to one side of the Hyd Sep and the system gets piped to the other.
Also the domestic hot water indirect loop must be tied into the boiler loop supply line before the Hyd Sep so it receives the hottest water possible.
And as far as engineered drawings I have had to train a few engineers.
They tend to use boiler plate drawings without thinking.

LENNOX pressure switches

@ January 23, 2014 11:45 PM in LENNOX pressure switches

Have You guys been having a lot of LENNOX pressure switches that are about 1 1/2 to 2 years old???
They got cheap on the switches and didn't use gold contacts. I think they should have a recall. I am sick of changing these switches.

quick

@ January 22, 2014 11:05 PM in replacing a sensor

If you can isolate the boiler with valves, then drop the water pressure of the boiler to 0 with the relief valve, then just prep the new sensor and do it quick. UNLESS water can get on any electronics.

valve

@ January 21, 2014 8:48 PM in Mixing Valve Noise w/Video & Audio

On domestic water it is usually called a Tempering valve.
On a boiler the same valve is a mixing valve - used to lower the boiler water temp down to a lower temp.

Wood/coal - oil

@ January 20, 2014 7:53 PM in Wood-oil-coal boiler ?

There are units that you can install inside the house that the law won't apply.
Your homeowners insurance will be higher ( make sure You tell them )
They work pretty good on wood and coal but not very efficient on oil so use it for backup only.

WOW - that is a small one for me.
I do commercial also. ( A LOT of church's )
I tend to remove one BIG boiler and install multiple smaller ( 399,000) boilers staged together.
Lowest savings I have seen is 33%
Highest was 66%

indirect

@ January 20, 2014 6:44 PM in Boiler Correct Size

It all depends on how the indirect is piped and wired in.
If it is a zone but doesn't have priority then You will need at least 40,000 extra BTU's
If it is wired and piped with priority then no extra BTU's are needed ( how I do it )
R Mannino - If you are the installer then explain why You installed such a huge boiler.
I have a HTP 199,000 heating a 8000 square foot 2 story house and it does indirect also.

Two pumps

@ January 19, 2014 10:01 PM in how do I control the boiler with a 4 way mixing valve and ecm pump

With a cast iron boiler and the Taco injection control you only need the system pump and the injection pump. ( cheap Grundfos )
A 4 way mixing valve with the motor drive will cost WAY more than an extra pump.
A 4 way valve without the drive motor won't control boiler temp and it won't do outdoor reset or boiler safety.
If you insist on the 4 way - Taco makes a control for that also that is real nice.

Taco

@ January 19, 2014 8:02 PM in how do I control the boiler with a 4 way mixing valve and ecm pump

Taco makes an injection control that would be a better choice for doing what you want.
You can install an outdoor sensor to control the mix temperature and it has boiler control and boiler return temp safety. The TACO PC 705 control has the piping diagram.

@ January 19, 2014 7:54 PM in Boiler Correct Size

Is it also heating your domestic hot water for baths and showers?

boiler size

@ January 19, 2014 7:34 PM in Boiler Correct Size

It all depends on everything - the amount of windows, doors, insulation R values. age of house, updates to all of the above.
If this was an average 20 - 30 year old house I would think 100,000 should be plenty. 80,000 could even be enough in a lot of cases.
Nothing against plumbers but if they don't specialize in hydronics  they shouldn't be installing boilers.

We need more info and pictures of your boiler and near boiler piping.
