Depends how deep the mains is, the deeper the warmer.


Not quite. The deeper the less the rate of temperature change. Here
we are talking about seasonal effects.


You are thick at times. I said that once below a certain depth the temp is
always the same. "No" seasonal changes, always the same.


That depth would be very considerable and certainly more than that
used in the UK for mains.


You could get a
large coil of 32mm MDPE pipe, take it off the mains and bury it as deep as
possible in the garden. Constant mains temp all the time.



ROTFL. Do you have any idea of how much storage and hence length
would be needed to achieve that and the flow resistance involved?

32mm MDPE pipe has an inside diameter of 26mm.

To achieve the 300 litres needed to make a difference for your box of
tricks, would involve 300,000 cc. volume

300000/(pi x 2.6^2) = 14126cm of pipe.

Over 140m......


You are joking of course......

Much better to get a proper storage system than to play around with
this nonsense.
