I have a utility room of similar size, which on frosty mornings I warm up with a fan heater set to 1kW, as it is used for washing and ironing. I actually use a timer for it. It becomes comfortable in minutes, I don't know how long the internal wall surfaces (CWI) take to warm.
I actually put in an 800W infra-red heater when refurbing it, years ago, as there is no radiator. I don't know if it has ever been used, as I fitted wall cabinets not long after.
