Calor gas heaters

[buckingfrolicks]

Hope this is more or less the right place to ask this.

I have bought a calor gas heater to use in the room where I work, so as not to put the central heating on wastefully. Yes I'm in a million layers, have hot water bottle on feet etc but it's an old house and I'm too cold to work

So DP comes home and we have a massive Row because he says these heaters are awful, make the house damp, and I'm not to use it!

Anyone know if he's right?
