Hi.. i had my boiler fitted about 8 months ago along with vsmart thermostat and it worked fine until a month ago. My first set of batteries lasted a good few months but last month they lasted for about 15 days (energizers) and the set after that lasted about 10 days (phillips). Weirdly, heating comes on if i don't replace the batteries for a few hours and once came back from work to a boiling home (it was 28 degrees outside that day).
Does anyone else have this problem and any suggestions? How long are your batteries lasting?
