Kemerton heater question.

Away at the moment and it's not that warm at night so the heater has been put on just for a wee while to warm things up. Only some of the circular grills put out warm air. Is this right ? I imagine some draw in and some output ?? 
Also as we are on hook up we've selected electricity as the c
Source. I understand if on gas it would heat up faster ? It's actually just fine on leccy but thought I would ask.. 

Thanks !

Yes you're right about heating vents. Can't answer your question re leccy or gas as we haven't used it on gas. We carry a small oil free heater which we use at night if its cold . you can set it low and have it on during the night if necessary as its silent unlike the van heating which gives you the blowing noise .

It is normal for a gas/electric heater to have a greater power output on gas.  it will, therefore, heat up the interior quicker on gas.
The different power outputs, expressed in kW, will be detailed in the handbook.
