It may be this is only necessary on very cold days when the heat pump has not got enough oomph to Nicolahttps://www.blogger.com/profile/09162244617407392907noreply@blogger.comtag:blogger.com,1999:blog-7825957372675897778.post-13045842217839515702015-02-11T03:54:08.705-08:002015-02-11T03:54:08.705-08:00Be careful talking about air-source and ground-sou...Be careful talking about air-source and ground-source heat pumps together. (Outdoor) air temperature fluctuates a lot (-5 to +30C), while the ground temperature is quite stable (10-12C). On cold days, when we need most heat, it's quite easy to take energy from the ground (at 10C), but much harder to take energy from the air (at 0C). This means the heat pump has to work much harder, using muchAnonymoushttps://www.blogger.com/profile/07765877732205811470noreply@blogger.comtag:blogger.com,1999:blog-7825957372675897778.post-89892156061893043512015-02-11T01:25:14.993-08:002015-02-11T01:25:14.993-08:00you have mentioned very useful and profitable mess...you have mentioned very useful and profitable message for us.<br /><br /><br /><br /><br /><br /><br /><br /><br /><a href="http://www.vision4lifepro.co.nz/" rel="nofollow">Top Energy Resources</a>Anonymoushttps://www.blogger.com/profile/16500065841114593214noreply@blogger.com
