7 Cockpit Heaters, Why?

[jeffs]

I'll use it once or twice a year if it gets down in the low 40s, but I'd rather turn the heater on than put the top on.  Admittedly it doesn't do much, but helps a little keeping the hands warm.

The heater in my car is pretty effective at cooking the lower part of my legs. The upper half of my body is cold, so on average I’m okay.

I've used mine on cool days...works fine.

I love using mine. Life saver when there's no other option on a cold day. One of the biggest things that makes a 7 better than a bike for transportation. 

 

Also on a Zetec it's one of the only sources of heat for passenger. I went as far as trying to make a HVAC tube to channel heat directly to passenger that can be deployed as needed.

Here you go. I included a couple to show that the system on a seven is simple, with just holes in the sheet metal . 

 

 

I plan on taking out my heater.  My first Caterham, a 1979 model, had no heater and I never missed it.

 

I a going to guess that the outside slots in this photo are the where the hot air gets to the people's legs. 

 

Is the big round hole in the middle how the cold air gets to the heater?

 

Where does this cold air come from?  

 

I assume that if I remove the heater I need to cover up all of the holes with aluminum.
