I'm looking to install either a convector heater or infrared heater to our garden room. From what I can see, wall mounted infrared are more economical as they heat the object and not the air, but the object needs to be in line of sight to gain the benefit. Whereas a free standing convector heater heats the air so less economical.
I briefly thought about an air source heat pump but the cost is prohibitive. Any suggestions/recomendations?
