Why heat up when you are not there?
i review a SilverCrest RT2000 Programmable Radiator Thermostat.
Shows how to set it up for use in my house, and look at the cool features and refinements.
There should be around 30% to saving heating. By turning down the heat when, for example. your are at work,and at night when you sleep.
I can save even more,now that I only use my playhouse in the weekends.
