Series 1 series heaters in series or parallel

have this smiths heater in the s1 but it has no demisting vents. never been an issue as it only tends to get used in summer. however my daughter wants it as her daily drive to college assuming she passes etc.



have thought up ways of adding holes for hoses but I doubt the airflow it generates will be sufficient to be of any use after passing down a tube. so I am going to move it to the tub as a second heater and add one of the t7 compact heaters.

putting them in series would be easiest installation wise but I understand fluids are similar to electrics - sure I read it on here somewhere - so parallel would be easier for the tired old water pump.

anyone know if the system would cope with them in series?

You're more or less right in your thinking - turbulence makes the fluid flow/pressure non linear and electricity doesn't suffer from that, but at low speeds it not a huge effect. In theory, parallel would be better.

In reality, a) if your water pump was dying you know that it's the right time to change it anyway, and b) by the time you've balanced the flow through the two parallel heaters you've further eroded the benefit. I'm making my cooling/heating system series if that helps.

balancing the flow? didn't know about that but I can see the logic, wouldn't want most of the heat disappearing into the tub one since that has probably the smaller - least resistant? matrix - series would be less joints to leak and no balancing so I shall just do that then thx for the reply

It don't have to be hot air to demist. In fact hot air can cause a few seconds of more condensation.
With this in mind and the fact if you have to wait for the water to warm before they work, it may not be the most practical solution.
An in line fan fitted behind a simple steel panel in the dash could quite easily run a couple of tubes to the screen.

Just a fort like.

How much will it cost to insure your daughter to drive it if she's just passed her test?

got a quote from flux at the start of aug £2k fully comp £1200 3rd party, £2k seems to be the going rate, same as putting her on the doris' pug but she is adamant about the s1. flux were the only people who could give a quote most wouldn't touch it because of the cars age which is silly imho. classic insurance is out till age 23 iirc. I mean it has been on the road for 60 years and never had a claim

hadn't thought of that, I do actually have a smiths box with a motor, fan and tube holes - assume it sucked hot air in from a separate matrix. have a couple of smiths flatties which won't go on the s1 bulkhead properly mainly because of the gear lever so would have to be off set - as the current one is - they would look a bit silly but I could stick one of those in the tub

Interesting. I'd investigated this for my sons and Heritage as you say have a minimum age (25) and mainstream insurance is sky high. I can get quite cheap insurance on me and my wife's policy for a Polo, its how mainstream insurers treat older vehicles, most don't even recognise an S3 let alone an S1. Numpty world we live in.

go girl do my s3 with her as a learner for £30 pm - it was £60 last year - but the premium more than doubles on passing but still cheaper than anyone else, they won't cover the s1 though, they told me it must be an import because they don't have it on their system, even when I pointed out it was made in Birmingham and so stamped they wouldn't touch it

she doesn't want the s3 as her car because its diesel, blue and the front grill looks crap and the s1 is way cooler. I actually prefer the 3

So change the engine for a petrol one , paint it green , put a Series One grill on it and bash the wings flat . It'll be cheaper in the long run !

What ever you do don't bother with one of those dash mounted fan/heater things that run from ciggy lighter.
Apart from making a noise they do little else.

had a couple of those ceramic jobs in the 110 20 years ago that weren't bad at helping thaw the screen while the engine warmed up, didn't think they were particularly safe to leave running. certainly wouldn't want anything requiring a lot of amps to power it on old series wiring.

The ambulance has a matrix in the rear with a separate blower in the cab above the driver door.

It's plumbed parallel with no isolation for the rear matix. ...it's either got hot water flowing to it or not along with the standard Series III cab heater.

Can't say the cab heater is any worse than any other Series III I've driven but when you flick the blower on for the rear the cab heater cools noticeably.

The hoses look to be the same bore and I haven't seen any valves etc that could be used to balance the system.
