Hi,
I'm after advise on a underslung water tank freeze protection system.
I thought of something with readily available and cheap parts, but unsure of the viability and safety of it. (See pictures)
Any advice/suggestions or budget friendly alternatives people have used would be very appreciated, cheers.
