Hi,
Ive a closed CH system and everything works fine until i turn on the HW tap.
Its running hot but has no pressure at all and just trickles out, someone said it could be an airlock? any ideas that could be causing this prob?
Cheers.
hi, CH heating is on and works, but the hot water tap seems to go cold after 16-20 secs,there\\\'s no constant hot water, its intermittent, has anybody any ideas why this is so? cheers.
