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

The Ecocent has been extensively tested by http://www.bre.co.uk/ 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.
