Waste Water Heat Recovery ~ 63% Efficient

The RECOUP Pipe+ 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 Pipe+ recycles up to 63% of the heat and returns it into the system.

The Recoup Pipe offers the following benefits:

  • Saves energy that is otherwise wasted
  • Reduces heating bill
  • Reduces CO2 emissions
  • SAP appendix Q eligible
  • KIWA validated up to 63% efficient
  • Virtually maintenance free
  • Easy Installation

Waste Water Heat Recovery ~ 63% Efficient

How It Works

The general princable 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.

Methods of Installtion

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 differents ways;

  • SYSTEM A - Preheated water supplied to shower mixer (cold inlet) and DHW heater.
  • SYSTEM B - Preheated water supplied to shower mixer (cold inlet) on the shower only.
  • SYSTEM C - Preheated water supplied to DHW heater only.

The performance of the above systems are recongnised within the SAP Product Characteristics Databse (PCDB) for energy savings calculations, although system A will produce the highest efficiencies.

Locating the RECOUP Pipe+

The RECOUP pipe needs to be installed vertically on the floor below the shower. Installation should take place on a flat wall using the fixings provided, and should allow for access to all parts for routine maintenance (e.g. Cleaning) to be carried out with relative ease. For further installation information please see the installation instructions


The maintenance required for the RECOUP Pipe 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. To clean, remove the cap and pass through a 30-40mm brush attached securely to a plumbing spring that is 2m or longer in length. Once cleaned, replace the cap and rinse through with warm water from the shower.
