i have forced hot water there is water on the side on the floor looks like overflow? can this be adjusted second ?? i am unable to get heat off i have turned off thermostat but heat continues the only way toshut is to flip emerg switch anything i can do

 

Wow, that's a tough read !

OK, so let's get this straight... you see "water on the side" ? On the side of what ? where ?

And, you say the heat won't shut off ? That could be dangerous, no ?

You might want to get a technician in there to look things over for you ... if you have to flip the emergency switch, then that should tell ya something !

 

ok its on the right side , it looks like overflow not alot of water but some , boiler doesn't come on constantly. with theremo set to zero i'm still getting heat in vents burner was serviced just b4 the season , its a tankless system also maybe this info willhelp

 

On the 'right side' of what ? the boiler ?

It sounds like your PRESSURE RELIEF VALVE is 'weeping', meaning the pressure in your boiler is too high.

Can you read the gauge and tell us how many PSI are in your boiler ?

This may be caused by some trouble with your expansion tank.

Also, the trouble could be with your tankless coil.

Or, it could also be trouble with your PRESSURE REDUCING VALVE that feeds water into the boiler.

If the pressure in the boiler is NORMAL ( meaning somewhere between 12 and 20 PSI ), then it is possible that the problem may be with the PRESSURE RELIEF VALVE.

Please notice that there is a difference between a pressure reducing valve, and a pressure relief valve... two different animals.

 

r side of boiler szs boiler pressure valve it runs out the top and along the r side dripping abit. pressure is 19 or 20 . is it possible when i shut off thermostat that the boiler is forcing the excess back into radiators? I know my hotwater in taps and shower doesn't last as long as it did b4.any help is appreciated

 

Perhaps Americanized English is not your native language and if this is true then I apologize in advance for the following.

I cannot understand what the heck you are asking. Could you possibly use standard spelling and grammar and also add some pictures so that we could help? Pictures need to be posted to a photo hosting site and then the URLs posted here.

 

Guess I will slow it down for you.

The Boiler is weeping from the "right side", tag says it's the Boiler pressure Valve. Pressure on gauge is 19-20 psi . I shut off thermostat "zero" but heat still comes out of my forced hot water system into the radiators. I am Looking to see if anyone has an idea what could cause this ? Could it be the thermostat?

p.s. system is tankless and since thermostat has been turned off the hot water in the faucets and showers are not hot for very long. Hope this is easier to read

 

Tell me, when you read the 19-20 PSI , at what TEMPERATURE is that pressure reading ? Is that when the boiler is HOT ?

If the pressure relief valve is 'weeping' at 19-20 PSI, one of two things... either:

The gauge is not accurate, and the pressure in the boiler is really 30 PSI, and the boiler pressure relief valve is doing what it is supposed to do, that is, relieving excess pressure.

OR

The gauge is accurate and the relief valve needs to be replaced.

Before I did anything, I would verify the boiler pressure with a known good accurate pressure gauge.

If the pressure relief valve is over 5 years old, I would go ahead and change it in any case.

I believe you will find your problem to be with your expansion tank.

Your expansion tank probably does not have the correct air charge in it, if it's the type that looks like a gas grill propane tank.

If it's the type that's strapped to the ceiling above the boiler and looks like a big tank, it could be waterlogged.

p.s. if the boiler is turned OFF, your hot water won't be hot.

 

I have lots of ideas but I have a lot of trouble trying to understand just what you are trying to write.

If English is a foreign language to you then I apologize.

Boilers do not have an "overflow" nor does any residential thermostat that I am familiar with have a "zero" setting.

Right side or left side is utterly meaningless without having a picture of what you are trying to describe.

If you have a tankless coil within your boiler to supply domestic hot water then the boiler WILL stay hot at all times. If you turn off the power to the boiler then you will have about a gallon (more or less) of hot water before it turns cold.

Trooper has given you good information.

There are many people here with decades of experience. There are very few problems that we cannot help you solve but you must help us to help you. Clear descriptions and clear pictures of your boiler and piping systems always help us to visualize your system. All systems have some unique parts to them so it is impossible to give you generic "fix it" information for a specific problem.

Pictures should be both close ups and from a distance that allows us to see the entire installation. The pictures need to first be uploaded to a photo hosting sight and then the specific URLs posted here. More pictures are always better than fewer.

 

Ahhh, yes, that's the part I was missing, thanks furd !

Now I think I understand what sully is trying to tell us ...

The boiler stays hot all the time ... yes, what furd said, this is NORMAL with your system ... and the radiators may be hot also ... but if the radiators are staying hot all the time, that is NOT normal.

Your system should have FLOW CHECK valves on it.

Those valves are supposed to prevent the water in the boiler from circulating when the thermostat is NOT calling for heat.

If those flow check valves are not set correctly (or not installed), this could happen ...

Set up a free account on www.photobucket.com and upload a bunch of pics there, provide us with a link to look at the pictures. Maybe we can spot the flow check valves and tell you what to try.
