How easy is it to switch from a conventional water heater to a tankless hot water heater?
It is relatively easy to begin using tankless water heaters. Units must be properly sized based on maximum anticipated hot water flow rate to meet peak demand. To do this, you, or the contractor/ plumber that you are hiring, must determine maximum temperature rise (cold inlet to hot outlet) and typical maximum flow rate. For whole-house electric units, a qualified electrician must provide up to four, 30-amp circuits.
