    what is happening is that water is collecting in the elbow and not running away properly. (I suspect if you look closely you will see that the angle is wrong..)

    as the heater only comes on every 6 hours it has the intervening time to freeze. -which it does of course, expands and splits the elbow.

    90 or 45 or any pipe will suffer the same fate due to this happening. sort the piping and the problem will go away..

    hi, so what exactly would the procedure be to sort the piping out ?
    make sure its on a slope so gravity pulls the water away before having a chance to freeze up?

    make sure that the trap (if it has one fitted is) outside the room.
