Hi - no need for anyone to reply. I've realized that the thermal conductivity of insulated is about 10x lower so whatever the cost, the energy required will presumably be about 10x the amount so insulated. I think this equates to an annual cost of £3000 vs £300 so it's a no brainer. Insulated it...
Hi all,
I'm sorry if this is an inappropriate question. I have built a basement swimming pool for my wife. Unfortunately I neglected to insulate outside the concrete and insulating inside the concrete has caused some construction issues so I am trying to work out the heat loss if I go ahead...
