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.

Snowmelt systems play vital roles as safety measures for air ambulance helicopter pads and on steep ramps. These systems typically operate by pumping hot antifreeze through a series of tubes under the asphalt.

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.

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

The chart below lists some common models of brazed plate exchangers and their specifications. To find an optimal and high-efficiency brazed plate exchanger for your snow melt application, contact a Valutech specialist today and we’d be happy to assist you!

We review the two hot water system types and compare the pros and cons of both, as well as the prices, to help you make an informed decision.

Tankless gas hot water systems produce about 75% less CO2 greenhouse gas emissions, when compared to a storage tank hot water systems powered by coal-fired electricity.

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

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.

Snow melt systems traditionally rely on brazed plate heat exchangers, usually to separate the antifreeze from the the hot water in the boiler circuit. We carry Alfa Laval’s line of brazed plate heat exchangers  which provide optimal performance, reliability, and highly efficient heat transfer capabilities.

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.

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.
