Hi all,
We had someone out to our Oso direct unvented cylinder recently as it was dripping tepid water from tundish when running. He recharged the internal air gap and all was well for a few weeks, but then the same problem reoccurred - tepid drip when heating element running, although the water from the taps was much hotter than that. The drip stops within a couple of minutes when the heater is turned off.
Having sought his advice again, he suggests fitting an external expansion vessel and replacing the TPRV. The cylinder is about 12 years old.
There isn't much space where it's sited so an external expansion is going to eat into our already very limited storage space, could there be any other options short of replacing the whole cylinder? Is it going to be worth us sticking an external expansion on a cylinder of that age (not sure how long they're supposed to last anyway)?
Thanks in advance for any advice!
