I'm looking for something portable to occasionally use to heat my conservatory a bit in the colder months so I can use it. Is an oil filled radiator the best (in terms of both efficiency and heat output) or should I consider something else (like not bothering because it's a waste of time and money) I've just gone through the rubbish job of lifting the old conservatory floor tiles and the screed to instal Heatmat on Thermal Insulation Boards...messy job, but oh my the difference is incredible, now have a room that can be used all year round. Had been considering installing a woodburner, there are a few rules, but it's doable Mine is only used occasionally in the depths of winter, so when I want to use it I fire up a Master gas fired space heater linked to a propane bottle piped through a wall outside. When everything is heat soaked, which doesn't take long with one of these I turn off the deafening space heater and maintain the temperature with a 3kw fan heater. Works well.

Would you mind sharing how big an area you covered and how much it cost? Would you mind sharing how big an area you covered and how much
