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.

Safetyvalve

A hot water tempering valve or hot water tank mixing valve does this by mixing in cold water with your hot water, before it reaches your taps.

With tankless systems, the prevention of bacterial growth is not an issue, as there is no stored water in which bacteria can breed.

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

A hot water tank mixing valve maintains a high tank temperature whilst simultaneously providing more tepid water for taps.

When you first turn on the tap, there is typically a delay in getting hot water, as the water in the pipes leading from the water heater to the tap will be cold.

Unless a minimum of 60°C is maintained, hot water tanks can be a breeding ground for Legionnaires’ disease, or Legionellosis, that is caused by a bacterium, Legionella pneumophila.  It is a respiratory disease that can cause severe pneumonia and is sometimes fatal.

Tankless systems can also be set at 50ºC, so the risk of scalding is greatly reduced without the need of a tempering valve.

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.

There are different types of hot water tank mixing valve or hot water tempering valve for different types of hot water heaters.

However, Canadian studies have shown, even when the thermostat is set at 60°C, a high percentage — approximately 40% — of electric water heaters remain contaminated.

Mounted flush against the wall, the smaller tankless units take up less space and are also more aesthetically pleasing, as they don’t dominate the exterior appearance of your home.

The Rinnai Smartstart® Water Saver was developed to reduce water wastage whenever a hot water is turned on.  It pre-heats the water in the pipes before you turn on the hot tap.
