Ffion Dimplex seem to have quite a good electric radiator range - have a look at this webpage with soem sleek black ones : http://www.dimplex.co.uk/products/domestic_heating/installed_heating/panel_heaters/glass_fronted_xx_range/index.htm If you're not in the flat during the day they will probably be your most cost effective option. However, if the flat is in occupation you should really consider other options for heating such as a small heat pump which would although more expensive to install is less expensive to run - heat pumps work on the basis of energy conversion which means that generally you get some 3kw output whilst paying for only 1kw. (With electric radiators if the radiator is 1kw you pay for 1kw). Os ti angen mwy o wybodaeth rho ganiad neu ebostia fi. Pob hwyl Gareth

Thanks for comments - yeah I think you're right on the last two minnie101 - part of me was tempted as I've seen some nice high contrast graphite radiators but you probably need the right interior to make that work. I too found the pics to be inconsistent and also the pics look very different to the RAL guide I have. They will send some sample/swatches and I will go from there - but it seems like it's narrowed to the first three. Hope the Oyster or Agate work out as they are both matt whereas the white is shiny.... Thanks so much!

I’m also in the middle of a garden office build and went for this brand: https://www.electricradiatorsdirect.co.uk/ecostrad-allora-designer-electric-radiators/?gclid=EAIaIQobChMIyYHsjYKO9wIVR-3tCh2cCgBKEAAYASAAEgJI-vD_BwE Electric radiators filled with thermoil, which retains heat even after it’s switched off. Haven’t installed yet, so can’t tell you how effective it is! I’m also installing a single room heat recovery ventilation unit, as the room will be reasonably air tight and well insulated.

Best electric radiators, what kind, where from? We have no gas & have these at the moment 🤮
