Undersoil heating for me is a nice to have rather than a necessity. We have frost covers and the only reason the game was postponed like most games this week is the fact the ground was frozen after a number of days or nights during the week with sub zero temperatures and wind chill.
I would sooner the club spend money on players or enhancing the matchday experience first and foremost. Also I’d prefer the club to spend it on an investment that may bring money into the club to help it be more sustainable.
Only if we got to the highest level would it be worth considering in my opinion.
