Yeah good point, I still have heating issues in Sylvia and the Carver Fire won't be sufficient as it is to heat her in the Winter. I am looking at second hand propex on EBAY and seem to go for anything from 190 to 250Is there a general problem with any of these flueless type gas heaters with water vapour? I used to use a portable Calor Gas heater in my first flat and the windows and even walls were dripping after a while. It was like when you let a kettle boil for ages.
