rayjackson1950 Posted February 3, 2021 Share Posted February 3, 2021 I currently do not have a heater.The Caterham heater looks easy enough to install but isn't cheap, so I wondered if anyone has used an alternative second hand or new one from another car.

Leadership Team SLR No.77 Posted February 3, 2021 Leadership Team Share Posted February 3, 2021 Do you have the cutouts in the engine bay to take a heater, likely covered with a large right angled plate? For a 1997 car the current Caterham heater is the wrong one, the correct heater that fits the cutouts (if that's what you have) has a large "7" on the casing, likely only available used.Stu.

Wrightpayne Posted February 3, 2021 Share Posted February 3, 2021 I have a 1998 car and this is the type of heater I have fitted. As Stu says you will either have cutouts in the bulkhead covered with a plate or no cutouts. This is called the fresh air type heater and links up with a set of louvers on the bonnet to blow cold air into the cockpit.https://www.ebay.co.uk/itm/Caterham-7-Genuine-Caterham-heater-matrix-blower-complete/143915126951?hash=item21820290a7:g:CZcAAOSw0Ihf~BypThere is an earlier metal box type heater which just has holes in the horizontal panel on the bulkhead. This just blows hot air. A picture of the bulkhead will help us advise what needs doing. Ian Link to comment Share on other sites More sharing options...
Tazio Posted February 3, 2021 Share Posted February 3, 2021 Or you buy an aftermarket heater from Demon Tweeks... Link to comment Share on other sites More sharing options...
rayjackson1950 Posted February 4, 2021 Author Share Posted February 4, 2021 Hi StuYes I have the cut outs plated off, as the piccy. Caterham sell 2 - heaters one of which is labelled S3 which I emailed them and they tell me will fit my car. I have shown the link below;https://caterhamparts.co.uk/heater/5380-heater-assembly-s3-sv-csr.html Link to comment Share on other sites More sharing options...
rayjackson1950 Posted February 4, 2021 Author Share Posted February 4, 2021 Hi IanI Have a cut out which is plated, as the piccy below;I have also emailed Caterham and they tell me that there's does fit, I attach the link to it below:https://caterhamparts.co.uk/heater/5380-heater-assembly-s3-sv-csr.html Link to comment Share on other sites More sharing options...
rayjackson1950 Posted February 4, 2021 Author Share Posted February 4, 2021 Hi TazioI looked at Demon Tweeks, but with all of theirs I would have to make up an air inlet box to go to the bonnet grille, as I don't fancy pulling the air from the engine bay, Link to comment Share on other sites More sharing options...
7 wonders of the world Posted February 4, 2021 Share Posted February 4, 2021 This one can be mounted inside the car if required, there are a host of bulkhead plumbing solutions available too.https://www.demon-tweeks.com/uk/demon-tweeks-micro-heater-tsdmch/I have it on my list...... just incase SWMBO kicks off and insists on toasty toes....

Leadership Team SLR No.77 Posted February 4, 2021 Leadership Team Share Posted February 4, 2021 The two heaters that Caterham sell are for either the swoopy CSR dash, or everything else. The one you've linked to is for the latter.However, both are for the later style (post 2014) bulkhead cutout as per the picture below. If your car is earlier and has the holes in both the vertical and horizontal panels, hence the angled blanking panel, you'll either need an earlier style heater, or you'll need to blank off / modify the cutouts you have.For a 1997 car, behind the blanking plate in the vertical panel you'll have a very large hole, nearly the size of the blanking plate itself, and in the horizontal panel you'll have two smaller holes, from memory approx 2" x 3" each. These would need blanking down to replicate the later bulkhead and plain heater tray, "heater tray" is the correct term for the horizontal panel below the bulkhead panel.Stu.

john g Posted February 4, 2021 Share Posted February 4, 2021 Don't know if it makes any difference but Rays car is a XFlow and the heater fitted to that chassis/engine was different to the K series chassis/engine Just a thought. Link to comment Share on other sites More sharing options...
Wrightpayne Posted February 4, 2021 Share Posted February 4, 2021 I think the heater is age specific not engine. I have a '98 chassis and the bulkhead plate I've just removed is identical to the one above and I have the plastic cased heater with the 7 embossed into the front. My chassis has the round blanking plate pictured above too. Link to comment Share on other sites More sharing options...

7 wonders of the world Posted February 4, 2021 Share Posted February 4, 2021 Most crossflows were the early flat type 'non fresh air' version which simply blew under bonnet ir through the matrix, later ones took air through the extra set on bonnet louvres hence their 'fresh air' name Link to comment Share on other sites More sharing options...
Wrightpayne Posted February 4, 2021 Share Posted February 4, 2021 I guess removing the blanking plate will reveal all!I thought the shallow metal box heaters covered a much bigger area on the horizontal part of the bulkhead and just had vents going downwards.

john g Posted February 4, 2021 Share Posted February 4, 2021 Think the '7 Wonders' heater #15 is a Clayton heater? Link to comment Share on other sites More sharing options...
Wrightpayne Posted February 4, 2021 Share Posted February 4, 2021 Could be - the OP's car is a 97 and mine is a 98 K with the plastic heater so not far apart in the production. I'm not sure why a tall blanking plate would be used on the vertical of the bulkhead unless there is a hole there?I guess any heater can be fitted with the corresponding scuttle panels.

Leadership Team SLR No.77 Posted February 4, 2021 Leadership Team Share Posted February 4, 2021 The type of heater will be based on the chassis and particularly the year, not the engine.Stu. Link to comment Share on other sites More sharing options...

Leadership Team Toughie Posted February 5, 2021 Leadership Team Share Posted February 5, 2021 I've seen one of your cars, Tazio. The way you had it, you might as well mount a heater on the rear number plate for all the good it would do. Link to comment Share on other sites More sharing options...

Sooty Posted February 5, 2021 Share Posted February 5, 2021 Heater? Whats a heater? Took mine out 2002 and not missed it once in my 89 xf. There is enough heat soak through the tunnel even though it is insulated. Heaters are for wimps - awaits explosive backlash! Link to comment Share on other sites More sharing options...
