The valve incorporates a factory set, non-adjustable Pressure Reducer/ Strainer, an Expansion Valve connection a single Check Valve and balanced cold feed. The valve can be fitted in any orientation to suit the installation, however, ensure that the valve is installed with the direction of flow arrows (stamped on the side of the brass body) pointing towards the unit (in the direction of the flow of water). -
Page 18: Warnings
Whilst secondary returns do make for greater comfort by having hot water immediately available at taps, it is an energy sapping facility – it is recommended that all secondary returns should be fitted with timers so that circulation is not constant. PLEASE NOTE: All secondary return pipework MUST be very well insulated and, even then, may have a very detrimental impact upon the economics of generating hot water. -
Page 19: Discharge Pipe Work
v) For units with secondary coil facilities, please discuss the use of the coil, and a suitable configuration for use, with a suitably qualified plumber/engineer before proceeding to add a heat source to the secondary coil. 6.11 Discharge Pipe Work: It is a requirement of Building Regulations that any discharge from an unvented system is conveyed to where it is visible, but will not cause danger to persons in or about the building. -
Page 20: How To Connect To The Heat Pump
Note: The discharge will consist of very high temperature water and steam. Asphalt, roofing felt and non-metallic rainwater goods may be damaged by such discharges and you must take this in to account when fitting the unit. Should such damage be caused, ESP will accept no liability for any consequent damage so caused. -

Questions and answers
Can the Ecocent extract rate be raised to reduce condensation in a bathroom
The ESP Ecocent 200L does not have an adjustable extract rate specifically mentioned to reduce condensation in a bathroom. However, it draws air/heat/moisture from areas like bathrooms and uses a smaller motor than typical extractor fans, operating at a lower system pressure differential. This process effectively reduces the need for a separate extractor fan, which may help with condensation, but there is no direct indication that the extract rate can be increased for this purpose.
