Revel in the Luxury of Instant Hot Water, and Eliminate Water Waste to Save Precious Dollars With Recirculated Hot Water on Demand


recirculated hot water by Whywait PlumbingRecirculated hot water by Whywait Plumbing ensures that there is always hot water available when it’s needed at every tap.

Most of us know what it’s like to turn on the kitchen sink tap and wait and wait for the hot water to finally arrive.  Or even worse, to turn on the shower tap and spend frigid minutes waiting for that perfect showering temperature.

Not only is it frustrating but it leads to thousands of litres of wasted water going down the drain, a luxury we can ill afford.

Heating hot water is expensive today, especially if you use electricity. An on demand recirculated hot water system is the technology that we can install today to give you instant hot water in every tap. Plus it eliminates expensive hot water being wasted, reducing both water and electricity or gas bills.

Now, Whywait Plumbing has the answer with the installation of a Grundfos recirculated hot water system that delivers instant hot water, eliminates water waste, recycles cold water, and reduces your energy costs all at the same time.  And yes, anytime you need hot water, it will be ready and waiting for you.

The Whywait Difference in Recirculated Hot Water

At Whywait Plumbing, we supply, install, maintain, and guarantee the performance of your Grundfos instant recirculated hot water system.

Grundfos is quite simply the easiest and most economical instant recirculated hot water system as it can be installed on any electric, gas, solar or heat pump storage tank mains pressure hot water heater.

Grundfos utilises only one pump and one valve which can be extended to multiple valves depending on your house layout.

This means there’s no additional return pipe line to be installed. A Grundfos on demand recirculated hot water system has the potential to save over 60,000 litres of water every year.

Retrofitting a Grundfos on demand instant recirculated hot water system to your existing home is a straight forward exercise. The Grundfos system uses the cold water supply pipe line as the “return-line” to the water heater. A circulator pump is used to create a pressure differential that allows the cold and cool water in the hot water supply pipe line to by-pass (at low volume) into the cold supply pipe line through a thermostatically controlled valve that is mounted in most installations under the sink or vanity basin furthest away from the water heater.

Bottom line, the Grundfos recirculated hot water system installed by Whywait Plumbing, costs about half that of competitive brands and outperforms them all.
