Today, it was 250. Sampling over a few days: THAT'S WHY I WANT A DATA
LOGGER

A data logger won;t fix the problem, niether will buying an ardunio
whether it's fakeardunio from ebay or the latest verion with
wifi/bluetooth it'll be a waste of money, if you know you have 250V when
you should really only have 230V then that is what needs sorting, an
ardunio can't sort this problem out.

It doesn't *solve* the problem, but it supplies evidence of the fact that
there is a problem and the times when it occurs, which will (hopefully)
persuade the electricity supply company to investigate and rectify.

What intrigues me is that a fairly small over-voltage of 10V (*) is shorting
the life of the wallpaper stripper element so much. You'd expect other
heating elements (kettle, immersion heater, electric fire, cooker) would
suffer the same fate.


(*) http://www.twothirtyvolts.org.uk/pdf...n_230Volts.pdf says
230V + 6% -10% (so 216V to 253V) with a nominal voltage of 240V
