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

The 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%.

400% Reduction in savings

The Ecocent has been extensively tested by and subsequently entered into the SAP data base. In fact, it’s the only hot water production and ventilation system of its type in the PCDB/SAP listing. The upshot of the testing and SAP listing means that if the Ecocent is entered into the SAP calculations of a new proposed dwelling, then in many cases this renewable technology may be the only one needed to achieve a SAP pass. If combined with a Bioethanol Stove (which can cost as little as £69) it can increase the pass mark even further. However, if you entered an alternative tank and MEV fan for example separately you wouldn’t achieve any significant uplift in the result.

The SAP reports pictured below are for two of twelve similar dwellings that were recently surveyed. They consist of new build and renovation. They all passed SAP without the need to install expensive PV systems or other renewables and they’re all heated by electric panel heaters. This of course is an extremely attractive solution for developers/builders because of the reduced build and ongoing maintenance cost savings achieved.
