Purchased a helton heat exchange the other day and I am currently planning the big installation.
The instructions state to install it in parallel with the current system (just bridging across the heater hoses) where as my mates twine is in series between the engine and firewall.
I would have thought the system would be more efficent running in series.
Does anyone know any specific reasons why you would run them in parallel? Seems odd to me.

hi tim
i have one also the same as you.
the advantage i see in it is that you can open the car heater to reduce the flow through the helton so you dont then need to mix as much cold
water to get required temp.

Series gives you temp control via the heater controls
Parallel gives you straight heat and you control it how you see fit.

I have one on a HJ60 and
mine is in series but either way is ok
In parallel with the heater off all the flow is thru the exchanger and if it is too hot turn on the heater so some of the hot circulating
water by passes the exchanger
In series by adjusting the heater adjusts the total flow thru both the heater and exchanger giving you temperature control
Hope this helps

Hi, I am thinking of buying a Helton but am a bit concerned at the warm up time. I have a Prado diesel and have noticed that you can sit at idle for a long time before the temp guage starts to move. Does this mean that the
water will not get hot for a considerable time ??

Something I failed to mention was that I had a heat exchange in my 99TD jackaroo (the last truck) which I made myself.
It worked perfectly for the 100k I put on the clock but as it was getting old I decided to update when I got the prado. So basically I have had one before and I know a little bit about their operation.
From experience, yes you do need the engine temp gauge to be up at normal operating level which can take a few minutes driving and quite a while at idle.
There is 2 ways to overcome this. Shower after you've been out driving or if you want a shower first thing in the morning, kick the truck over for a few minutes then go for a quick drive up the road and before you know it, its right to go. This also gives the batteries a quick top up after running gear all night.

Couple of the guys I know that run HE's in parallel , run a separate Heater valve to the vehicle one.
This allows heat control from within the engine bay , rather then having to access the vehicle.
One of them even has a cable long enough to alter the heat from the shower tent itself.
