The water expands 40 times its volume very rapidly so the pressure relief valve cannot keep up and boom. It is the most dangerous thing you can do to a boiler. It makes it a bomb. boilers were one of the first things patented.
I replaced the kickspace heater and everything was going fine until I turned it on and found that it isn't pumping water through the radiators.
The beginning of the pipes are hot, but not the pipes going through the radiators.
The pump starts making grinding noises after 1/2 hour or hour of being on. But it's not grinding right now.
Yellow target light is on. Red low water light is off.
Switching relay is making a low oscillating humming noise.
2nd floor zone works without flaw. So I guess (?) the boiler itself is working fine.
Is it possible I clogged the pipe with soldier? I only used about 2 inches of solder for the connecting sleeves. Which is about what I used on all the other joints, and I know there's flow there since I poured water through them before connecting it to the T joints.
the amount of money I make on installing recirc pumps for people that decided to cheap out on a tankless install from a non-reputable company for "instant hot water" is absolutely unreal.
They can have a harder time keeping up with higher demand which is offset by installing more units, a business earning profit can eat that expense easier than most homeowners can. Your point is why I think they're not bad for say a summer home where demand is lower and the thing won't be in use much of the year. Tank heaters also have the added advantage of being a water basin in the event of an emergency where water may be cut off.
I have one of these that's maybe 10 years old now
haven't had it serviced in 5 years
how long do they last?
what parts can I expect to break?
it was installed by my gas company so I assume it's a decent brand
we had soft water for awhile but I hate how it feels so bypassed the softener and back on hard water
no issues with it so far
Hard water kills tankless hot water heaters dead. Should switch it back to softened water, and if you haven't done anything in 5 years it almost undoubtebly needs to be descaled.
Are you upset about the redundancy in a very common name, or that OP said boiler even when he posted a pic of tankless water heater and I went with the device in the pic?
I bet you’re also the homosexual who “corrects” people when they don’t pause properly to pronounce the t in duct tape even though duck tape is actually correct.

Even if no earth shattering kaboom, the rapid contraction of the hot pipes can break joints.
Because flash boiling in the presence of flesh is bad, mkay
So...only cause the the over pressure valve will spray boiling water? OK, thought it would destroy the entire boiler or something.

>needing a computer to make hot water
Not my fault they put that shit in every modern unit.
OK, so this is a boiler for a heating system.

You have air in the line, brother. You have to burp it with a hose and the fill valve.
Thanks for the tip, following the below guide, and now I'm ready for winter.

Tankless heaters are kinda dumb for most non-commercial applications IMHO
why? heaters with tanks waste a lot of energy keeping it at temp setpoint even if you never use the hot water
Does it? Does it really?

ok thx anon I'll look into descaling it
>hot water heaters
>makes hot water
>further heats hot water to a set point
seethe and cope, it's technically correct

Tankless water heaters are boilers you nonce.
>heats water
>but not to boiling point
>it's a boiler, not a heater
I actually looked this up for that other guy, and modern "boilers" usually don't boil water, just make it hot, like any hot water heater.
fun fact: the La Brea tar pits to a person fluent in spanish and english means "the the tar tar pits".
