Forget Boilers use a Resin with a Chemical Heater !

Econorez 55 gallon ( 484 lbs )

A high performance styrene based resin with more working time than most epoxies but yet dries 60 minutes after working time, even in lower fall temperatures. This resin does not need the addition of hot water as it has its own inbuilt chemical heater that kick in after the working time has expired.
