Does anyone have 'actual' energy used for a Mechanical, Ventilation with Heat Recovery system please?

Vent axia publish documentation on the web for the air minder and more recent models which have the dc motor wattages and heat transfer efficiences if that would be enough to go on.

Thanks Bruce I will have a Google.

I'm just in the process of installing a Vent Axia Sentinel Kinetic plus.  So far it's plumbed in upstairs, but not downstairs.  It sits at 10% generally, taking 11W (I have it plugged into a socket, so used a power meter on it).  After a shower it bumps up to 50% for 20 mins ish.  I think thats 70W or so.  So far I'm very happy with it :-)

hello,

if theoretical 'actual' values are good enough then try here - www.sap-appendixq.org.uk/search.jsp

values down to 0.4Watts per litre per second are listed there
