Waste water heat recovery: Advantages

An innovative way to make your home more sustainable and save energy while showering, is using a heat recovery system (shower wastewater heat recovery WWHR).

In this article, you can read all about the advantages of shower wastewater heat recovery.

Making our homes more sustainable is becoming increasingly important, and reducing energy consumption plays a crucial role. Recent research shows that approximately a quarter (25%) of the total gas consumption of an average household is used to heat water, of which more than 80% is used for showering. Much of which flows away down the drain.

What is a shower wastewater heat recovery system?

A shower wastewater heat recovery system recovers heat from used shower water (wastewater) to pre-heat the incoming cold domestic water.

This means that less energy is needed to bring the water to the desired temperature, resulting in lower energy consumption and lower costs.

The principle is simple: as the warm waste water flows away, it transfers its heat to the cold domestic water via a heat exchanger. This process increases the temperature of the incoming cold water. Resulting in a lower load on the waterheater.

Advantages of a shower heat recovery unit

  1. Energy savings: By preheating the cold domestic water, a shower WWHR unit can significantly reduce the energy consumption on showering. Efficient WWHR units can reduce gas or electricity consumption for showering by approximately 50%.
  2. Cost savings: Lower energy consumption directly leads to lower energy bills. The exact savings depend on factors such as current energy prices, the duration and frequency of showering and the size of the household.
  3. Environmentally friendly: Reducing energy consumption also reduces CO₂ emissions, which contributes to a better environment.
  4. EPC / EPBD Last but not least, a Shower WWHR unit adds value  to your EPC / EPBD calculation and requirements. Especially when there is netcongestion or any other limitation on other energy saving measures, a shower WWHR is an excellent alternative.

 

Conclusion

A shower heat recovery unit offers significant advantages in terms of energy savings, cost reduction on energy use, cost reduction on downsizing the DHW installation and reducing CO2 emission.

Installing a Recoup shower WWHR system is a relatively low investment with a short payback period.

Recoup offers various solutions to fit any bathroom. Whether a new build is concerned or a renovation and even when there is no wish to perform any re-construction, Recoup has a product meeting every single challenge.
