When I first got my Morgan a year ago I had a bit of a service and some work on the rear hub brakes done at Lifes Motors
At the same time I asked them if they could replace the heater box filters as they were pretty well disintegrated
They did all the work I wanted and I was very pleased with the service and results and have continued to use Lifes and will continue to do so but I did wonder why my cockpit heater was so poor in that it just wouldn't put any heat in the car
Thinking it might be something to do with heat transfer from the engine or the fan, I investigated further and removed the filters that were put over the boxes
All became clear - the filters were far too dense to allow proper airflow - they were a dense foam with a dual layer paper/cotton type filter, the type ive seen in bag less vacuums
Mrs S and I went out in the Mog last night and I had to turn the heater off, our legs were so warm!
Moral of the story - make sure your filters are thin, coarse open filters that allow airflow if you need some heat
