ecodrain

It’s easy to ignore the disconcerting fact that heating water for showers and baths constitutes a huge proportion of the cost of your energy bill, as the overall total is hidden. But showers consume up to 80% of hot water in the average home. But it’s not all doom and gloom – because there’s no delay between hot water for showers being used and drained, showers are perfectly suited for heat recovery – which is where the Ecodrain comes in.

 

Here’s how they work

Ecodrains have the potential to save a significant amount on energy bills by transferring heat from hot shower waste water to cold water – which cuts down on water heater use by between 25% to 70%. The device is installed directly into the shower ‘drain line’, and has a wall separating fresh and waste water to ensure that never the twain shall meet.

 

A Tankless Task

Ecodrains can be used with the majority of tankless heaters, as long as they are installed correctly. Provided that the tankless heater is connected in-line, the Ecodrain system will preheat water which flows straight into the water heater. If the tankless heater is connected to the shower with a mixing valve, then Ecodrain can preheat the cold water which would lead straight to the valve – exactly the same process as with tank heating systems, but far more energy efficient.

 

Remind me what a tankless heater is again?

Tankless water heaters – also known as ‘continous flow’, ‘flash’ or ‘on-demand’ heaters, heat water as it flows through the device – so no water is saved internally. Tankless water heaters are becoming more popular due to the twin advantages of providing a continuous flow of hot water, and being more sustainable – when compared with your common-garden tank water heaters which have a limited flow of hot water, and have to constantly heat large amounts of water, which uses up more energy.

The tankless water heaters use sensors which detect the flow, and begin the heating process, setting the correct temperature automatically, by comparing the incoming water temperature with the desired heat. Pretty ingenious, eh?

So, no longer will your showering habits be a drain on your finances!
