Are the calortec radiators suitable for a static caravan and what is the weight of the units for wall mounting?

Also, the units I was looking at are the Elyosun 1.2Kw radiator and the 1Kw Fluid electric radiator, both priced in the argos cataloue at £164.99. What is the difference between the 2 units and why are they both the same price when one is more powerful than the other?

Thanks
