I have a low heat Glen Heater Model 2142 in my small airing cupboard. It's been there now for about 12 years. Recently, it seems not to be pushing out as much heat as before but this may be imagination. I have just cleaned some dust off it and checked that it isn't leaking or anything and all seems to be OK. Does anyone have any thoughts? Thanks

Hate to say it but at 12 years old I’d replace it with a new one . Simply due to the age and the fact the newer models will be more energy efficient and better safety devices.
I always wonder about energy efficiency and electric heaters - I’d assume a certain amount of energy produces a certain amount of heat - so as long as energy is not also being converted into sound or movement etc- how can something be more energy efficient?
Is there something I’m missing?
Old simple but reliable boilers with heavy cast iron heat exchangers are replaced with lightweight aluminium heat exchangers and these in turn will be replaced with ground and air heat pumps, standard light bulbs replaced with halogens and now get replaced by led,s . Petrol engines to hybrids to fully electric etc etc .maybe it’s a matrix thing because we’ve been conditioned to accept what we’re told . Even the pump and the fan in your heating boiler is more energy efficient- all down to the e u which we left or did we …

Let’s take it apart to see what’s inside….
I agree.
@brocher , if you want to check it out I can think of two simple methods…
1. Disconnect the heater and measure its resistance with a multimeter. For 120w, at 240v, you should see about 480ohms
2. Get a plug-in power monitor. These are available relatively cheaply now and will read the power consumption directly.
As Tom says, in this case it’s probably quite safe to assume 100% consumed power is converted to heat.
