Tankless gas hot water systems only needs to run when the hot water is actually required and wasteful pilot lights are a thing of the past.

Because it is kept hot, tank systems can be slightly faster in delivering the initial flow of hot water, as the tankless system takes a second or two for the unit to get up to temperature.

This keeps the tank hot enough to stop bacterial growth (>60°C) and a lower tap temperature (≈50°C) to help reduce the risk of accidental scalding.

Tempering valves have a temperature sensitive element which adjusts the mix depending on the temperature of the incoming water flowing through the valve.
