Abstract
A representatively pumpless water heater system has an instantaneous water heater coupled in series with a storage water heater by piping circuitry incorporating a fixed (and selectively fixed) bypass useable to route pressurized incoming cold water sequentially through the instantaneous and storage type heaters. The fixed bypass can also route pressurized incoming cold water to mix with the heated water exiting the instantaneous heater for delivery to the storage heater.
