@JeremiahFieldhaven@upmultimediahttps://www.argos.co.uk/product/9416217 are on offer at the moment. We have 3 of them - each kicks out a fairly serious amount of heat for such a tiny thing. The big wall radiator in our office gets the room up from ~13C to ~15C, and this tiny heater gets it from there to ~20C.
Unfortunately they are on the Strictly Prohibited list at my employer because they are deemed an Abomination Unto Nuggan and also a Major Fire Hazard (to be fair, they *did* have a fire incident in one building when a fan heater forgot how to do the 'fan' part and really put all its enthusiasm into the 'heater' part...)
Thankfully I usually only need to be on site once or twice a week. Home is proper temperature.
@upmultimedia I have an oil filled radiator in the office, but it's really struggling. The building my office is in has notoriously bad climate control (good old 1970s architectural masterpiece that it is)
