Kenlowe heater

Re: Kenlowe heater
I would look at the heater circuit. I presume it's always 'open' on that vehicle.

Re: Kenlowe heater
I’m not too sure to be honest
I can always take the thermostat out
I’m hoping that it warms the coolant enough to Demist it quicker

Re: Kenlowe heater
Bit curious. You remove the thermostat making sure the heater doesn't work and want to heat the coolant by electricity?

Re: Kenlowe heater
I've never known a V8 take long to warm enough to demist the car! Are you sure your thermostat is working?

Re: Kenlowe heater
Don't take the thermostat out!
Make sure its working - not stuck open, and re-fit.

Re: Kenlowe heater
Will test the stat this weekend
It’s just to thaw the screen in the coming weeks/months
Iv been spoilt as my Rav4 heated up in no time and had the best heater Iv ever had in a car

Re: Kenlowe heater
I don't think removing the t'stat is a good idea at any time but if you did then your pre-heater/pump would presumably be heating the coolant then pumping it around the whole cooling system, including the radiator which would then radiate that heat you've just added so even less good.
I think the heater circuit has to be permanently open on the RV8 as this is how the flow takes place when the t'stat is closed IIRC which sounds like exactly what you need.

Re: Kenlowe heater
All the race cars I worked on didn’t have a thermostat
Where would be the best place on the heating system?

Re: Kenlowe heater
Didn't realise this was a race car, so presumably no heater?
Depending on configuration should still have outlets in system for heater? Plumb it in there.
Re: Kenlowe heater
its not
It’s a disco v8 3.9 efi with a kenlowe day in its boot waitignto be fitted was just seeing if anyone had an real world experience of where to plumb one in
As surely the thermostat would restrict the flow of the hot water, if memory serves correct it heats to 45degrees
It was just to heat the coolant to clear the screen as I don’t have a place to park the car under cover

Re: Kenlowe heater
What not try a fan heater inside the car for a couple of minutes?
I have tried that, extension cable and run the fan heater for 3 to 5 minutes and the ice on the screen was completely melted!
Much more simple in my opinion!

Oh, so I'm a bit confused why you brought the subject of race cars up then.Stuvy wrote: ↑Sun Nov 15, 2020 2:45 pmits not

Anyway. When the thermostat is closed coolant must still circulate around an engine otherwise the static water would just boil in the head and that would end badly.
The T'stat only stops the coolant circulating around the radiator part of the sytem, which would be bad for your heater as it would be throwing away a significant amount of the energy supplied through the radiator. Even without airflow a radiator will still 'radiate'.
On the RV8 engine, at least all the ones I've seen, the heater system is permanently 'open' and this supplies a circuit for the coolant (unlike some other systems I've seen which have a valve in the heater system and must allow circulation via some other channel), this should give a convenient point for you to pipe in your pre-heater, as it would then only be circulating heated coolant around the engine, pre-heater and heater matrix.
OK, you will lose some heat via the heate matrix but this is also effectively a small radiator but this will find its way into the vehicle (if the vents are left open) so not exactly wasted.
Assuming the Kenlowe allows unrestricted flow when not in use it should be OK to plumb it into either of the pipes between engine and heater matrix, shouldn't really matter which.
Re: Kenlowe heater
My SD1 EFI has a vacuum operated valve which shuts off the flow to the heater matrix when the AC is in use. Perhaps they reckon you'll only use AC after the thermostat has opened?
