Actually desirable for northern locations as the heat pumps do pull heat from the building to work and the byproduct is chilled air so there is a heating loss. Works though in heat recovery - I ducted the exhaust air to the hot water tank pump enclosure and vented the chilled air. Be nice if a unit was packaged for that purpose. One of the best products I found (early pioneer in small heat pumps) is made by Nyle in Connecticut and its an add-on unit to any existing storage system so can be integrated into a hybrid situation really easily.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> Greenbuilding [mailto:greenbuilding-bounces@lists.bioenergylists.org] <b>On Behalf Of </b>Joe Killian<br><b>Sent:</b> April-29-15 8:03 AM<br><b>To:</b> greenbuilding@lists.bioenergylists.org<br><b>Subject:</b> Re: [Greenbuilding] Is this product desirable?<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal> Looks like a technically nice approach - a solar heat collector using some (un-named) fluid with a low freezing point so freeze-up isn't a problem, operable either on straight solar heat gain or if insolation isn't enough to attain desired temperatures then kick in a compressor and operate as a heat-pump from the panel to storage.<br> I wish they'd say that in so many words. The brochure wording has a shady character similar to many pseudo-science marketing scams. Yes, Nicolas Carnot. Heat pumps all, & most refrigerators, use the cycle named after him.<br> I'd ask for more specifications & performance test numbers and references.<br><br>Joe<br>physicist by training, engineer by profession<br><br><br>On 4/29/2015 7:43 AM, Gennaro Brooks-Church - Eco Brooklyn wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal>Can somebody who knows solar hot water heating tell me if this product is worth buying? <o:p></o:p></p><div><p class=MsoNormal><a href="http://www.energie.pt/en/products/ecotermo">http://www.energie.pt/en/products/ecotermo</a><o:p></o:p></p></div><div><p class=MsoNormal>It has a heat pump that uses 390W and creates 2900 Thermal Power W (whatever that is).<o:p></o:p></p></div><div><p class=MsoNormal><br clear=all><o:p></o:p></p><div><div><p class=MsoNormal>Gennaro Brooks-Church<br>Director, Eco Brooklyn Inc.<br>Cell: 1 347 244 3016 USA<br><a href="http://www.EcoBrooklyn.com" target="_blank">www.EcoBrooklyn.com</a><br>22 2nd St; Brooklyn, NY 11231<o:p></o:p></p></div></div></div></div><p class=MsoNormal><br><br><br><o:p></o:p></p><pre>_______________________________________________<o:p></o:p></pre><pre>Greenbuilding mailing list<o:p></o:p></pre><pre>to Send a Message to the list, use the email address<o:p></o:p></pre><pre><a href="mailto:Greenbuilding@bioenergylists.org">Greenbuilding@bioenergylists.org</a><o:p></o:p></pre><pre><o:p> </o:p></pre><pre>to UNSUBSCRIBE or Change your List Settings use the web page<o:p></o:p></pre><pre><a href="http://lists.bioenergylists.org/mailman/listinfo/greenbuilding_lists.bioenergylists.org">http://lists.bioenergylists.org/mailman/listinfo/greenbuilding_lists.bioenergylists.org</a><o:p></o:p></pre></blockquote><p class=MsoNormal><o:p> </o:p></p></div></body></html>
