I thought that I’d describe some of the features of the smart heating controls versus the prior single zone system with TRVs and a 7 day timer. My main interest is of course to save gas by heating the home more selectively, but there are other opportunities that you may consider significant.
I don’t yet have sufficient data to illustrate any operational savings, but continue to record gas consumption to compare with prior years.
