Does a tankless water heater make better sense than a solar hot water heater?
Not necessary, the water you use is still being heated by electricity and the amount of energy used to heat a gallon of water is the same. The tankless style heater only eliminates the energy cost to maintain the temperature, so it only 10 to 15% less expensive than your current electric water heater. Tankless units can struggle to provide all of a home hot water needs simultaneously, which may mean you have to wait to shower if the dishwasher is running. Solar hot water system can provide a 90% saving from your current water heater and will provide plenty of hot water.
