When it comes to reducing costly heat loss from homes and buildings, wall and attic insulation now has a new partner of sorts. This fellow energy saver is ReTherm. Where as insulation prevents the loss of space heat, ReTherm prevents the loss of domestic hot water heat that otherwise washes down the drain.

To better understand where a large part of home or building energy budgets are used look no further than the various faucets and machines that use hot water: dishwashing machines, sinks and especially showers. Consider for a moment how truly in-efficient energy is used when it comes to domestic water heating. A dishwashing machine uses and maintains water at temperatures as high as 65°C and at the end of each cycle all of this heat energy is thrown away. The shower is even worse because hot water is used only a few, brief seconds before it is thrown away with 90% of the heat energy still held by the drainwater.

Heat recovery systems have been used in the industrial sector for decades, but it's a fairly recent concept for single family homes, multi-unit residential and small commercial sectors. The reason for this has been the lack of a cost-effective, hassle free solution for these applications. But ReTherm is starting a revolution, more precisely, an evolutionary change in how people deal with hot water heating.

This natural evolution means that more people are looking at the big picture when it comes to hot water heating. It's changing domestic hot water from being very wasteful to very efficient. As more people rethink energy use the days of needlessly letting heat energy go to waste are becoming a thing of the past.
