indirect or direct electric resistance
I need to replace an oil boiler w/ tankless coil. The customer is very set on going with an electric wall hung boiler for the setup, likely a Slant/Fin. Is an indirect more efficient than an electric hot water tank? His new boiler will be off electricity anyway so in short the questions is does he add another breaker to the panel and put in electric HWT or use an electric indirect?
