In an average house up to 90% of the hot water is used for showering. Most of that heat goes straight down the drain with the waste or grey water. The Shower-Save is a very simple grey water heat recovery system. It can reclaim up to 60% of the heat that would normally be lost down the drain when you shower.
How does it work?
The waste water from the shower runs through a heat exchanger on its way to the drain. The cold water feeding the shower and the hot water cylinder / combi boiler passes through the heat exchanger and picks up the waste heat. Only the heat is transferred, the waste water never comes into contact with the fresh water. There are several models: The Recoh-vert (for use with upstairs showers), the Recoh-tray which is a heat exchanger integrated into a shower base (for use anywhere) and the Multi-vert for larger commercial buildings.
Save money
The low initial cost results in a very quick payback relative to other technologies. The Shower-Save will pay for itself many times over during it's long life. Average annual savings can be equivalent to a solar water heating system but at a fraction of the cost.
Reduce your carbon foot print
Shower-Save will save between 300kg and 1000kg of carbon dioxide emissions per year, depending on how often you shower and what fuel you heat your water with.
Meet environmental targets
The Shower-Save has proved so popular in Holland where it was developed, as a very cost effective way to meet environmental targets, that it is now installed in 20% of new houses.
Reliability
Simple, low maintenance design with no moving parts. Copper construction means the system should last for many years.
Performance
Official test figures show that the Shower Save can recover over 60% of the energy when you shower.
Other benefits
Reduces the re-heat time of hot water cylinders as the fresh water entering the cylinder has already been pre-heated. If used in conjunction with a solar water heating system you should be able to get the majority of your hot water from solar.
Applicability
Will work just as well with showers over baths, but not with with baths when filling and emptying are not simultaneous.
