The RECOUP Retrofit is the affordable solution to make substantial savings on the hot water bill. Almost all the energy used to heat the water from showers goes down the drain. The installation of the RECOUP Retrofit recycles up to 22% of the heat and returns it into the system. The Recoup Pipe has the following benefits and features ;
The general principle behind is to use the heat from the outgoing shower to temper the cold water coming in. It does this by filtering the waste hot water through the pipe heat exchanger. The hot water clings to the side of the pipe and the cold feed is passed over the pipe. The heat transfer from the outgoing hot to the incoming cold allows a temperature increase of around 15 degrees. The pre-heated cold feed then feeds the shower mixer, boiler and/or cylinder.
The inlet for the RECOUP pipe is connected to the mains water supply, and the outlet (pre- warmed water) can be connected in one of three different ways;
The performance of the above systems are recognised within the SAP Products Characteristics Database (PCDB) for energy savings calculations, although system A will produce the highest efficiencies.
The RECOUP Retrofit needs to be installed horizontal. Installation should take place on a flat base capable of supporting the unit using the fixings provided, and should allow for access to all parts and allow routine maintenance (E.g. Cleaning) to be carried out with relative ease. Ideal locations installation include under baths with showers, shower trays or even be boxed in next to your drain. For further installation information please see the installation instructions
The maintenance required for the RECOUP Retrofit is very minimal, however, it is recommended to clean the unit periodically to avoid any reduction in efficiency. This cleaning will remove any build-up of soap and dirt residue on the inside of the copper pipe where the waste water passes. This can be done by simply pouring 1-2 litres of hot water up to 70Â°C down the cabinet drain in 2 stages, with circa 5 minutes between.
