I'm planning to buy a new in-ground pool heater to replace my 13-year old Minimax NT 300.
I'm looking at a RayPak 336 NP electronic model.
Both the Copper and Cupro-Nickel models are the same price.
My question, looking at the heater specs it appears to me the Cupro-Nickel uses less energy?
The only BTU specs I see are "input", what is the actual BTU "output" for the 336 model?
Input BTUH Copper Cupro-Nickel
