I installed a piece of diamond plate on the wall in order to mount the boiler and auxiliaries to.
I put in a propane fired Navien boiler. This not only heats the floor, but also heats domestic water.
About 3-months later I had the concrete floor polished. I was going to go with an epoxy floor, but changed my mind.
The polishing is quite time consuming, but was half the cost of the epoxy floor.
This is the final top coat (ice cap) that gets burnished into the floor. It's not really a coating, but goes into the pores of the concrete.
