From a point of view of efficiency maybe but the FIT of PV panels is the major advantage ,assuming govt doesn`t renege on the deal in years to come.
If it was just about the electricity you would save then it wouldn`t be worth it.

Wasn’t the OP on about one of those deals where the company who pays for and installs the things gets the government subsidy? Solor heating is cheaper, and more efficent, so should save you more money if you’re not getting a subsidy.

I bet you’re quiet at the moment igm? 😀

Oh yes – one of the managers who works for me recieved an application for 12,000 PV installations the other week. And there were a few other applications over 1,000 that week.
