ESP Ecocent SAP Recommended Input Guide

SAP Input Instructions for entering hot water from an Ecocent Cylinder and MEV

Because of the number of enquiries we get about using the Ecocent as an MEV system in SAP software, we have devised this guide using the PCDB database numbers and highlight the various sections into which they must be entered: (Elmhurst ref)

PCDB Database numbers:

  • 200L Ecocent 190001, MEV 500487
  • 300L Ecocent 190002, MEV 500488
  • Maxi Ecocent 190003, MEV 500489

Section 19 (MEV) – Specify MEV – Centralised, MV reference number as above serving the relevant number of wet rooms.

Section 25 (Main Heating 2) – Specify reference as above (190001 etc as appropriate).

Section 28 (Water Heating) – Specify from Main Heating 2

This should allow the correct entry of the Ecocent as an MEV/EAHP System.

The Ecocent can potentially achieve an efficiency of up to 400%.

EcocentThe Ecocent isn’t just a combination of a mains pressure hot water cylinder and MEV fan; it’s the only unit of its type which is in the SAP data base. The Ecocent also has a built in Micro High Temp Air Source Heat Pump combined with a built in MEV ventilation Fan System which means that whenever the unit is in hot water production mode, the waste heat/air which would normally be lost to the outside via the MEV part of the system has the heat/energy extracted from it, up-scaled in temperature and recovered into the hot water via the built-in ASHP.

This means the Ecocent, depending on air flow rates, can potentially achieve an efficiency of up to 400%.
