Alternative to 2 ton heater?

[alextangent]

1993 xflow with the standard 2 ton hewn-from-a-lump heater. Are there any lighter and less liable to corrode alternatives? I quite like a heater -- keeps the tootsies warm -- but mine's rusty and appears to weigh about the same as a cyl head .

Hi

 

The current production Caterham heater is not very heavy (I weighed mine before fitting it so I have the exact figure somewhere). Most of the weight is in the blower motor.

 

Just looked it up - the heater unit weighs 2.1kg (only 510g of which is the matrix)

Yeah, but you can't fit the current heater on a 93 car without changing the bulkhead and bonnet.

 

The bulkhead needs a big vertical cutout for the new heater, which also breathes through 5 (or 7) slots in the middle of the bonnet forward of the scuttle. I know, I tried it!

Ah ☹️ that's a no then...

Not quite true actually. Provided you have the central louvres towards the rear of the bonnet you can fit the later fresh air heater. I know, I tried it! On my old car which came with the old heavy recirculating heater, it also had central louvre vents in the bonnet so I was able to cut a hole out of the bulkhead, plate up the oval shaped cutouts in the horizontal sheet and fit the new heater using Rivnuts to the bulkhead.

 

Worked well and looked like it was meant to be.

Nope, the bonnet's 3 louvres sets per side, and nowt down the middle. I'll just have to settle for removing the heater entirely, and see how I get on in colder weather.

The heater casing is only plastic so easy to modify - It can't be beyond the whit of man to arrange a duct to bring air fron the existing louvres to the blower. I'm not that keen on the louvres being directly over the heater intake anyway as the drain holes that are supposed to ensure the water coming in that way doesn't end up in the footwells are none too large.
