You don't seem to have a flow restriction valve on the pump outlet ?
Is that correct ?

I was aiming for a 50% flow rate per min, thinning my mash to aid is ness
I was hoping to use the HE to restrict the flow without using a valve.
I have just done 3 trial runs and the output from the return manifold is 11 ltr per min, which I'm quite happy with.
Wether I'll stay happy with that with a mash is another question.
When I conducted initial trials with the clear tube I got some interesting results.
With the tubing taught from tap to pump inlet the tubing was fine. Initially however I cut the tube with some slack and this caused the tube to collapse as the temperature hit mash temp

The reason I went for a high flow rate was for thermal efficiency.
My other pump managed 6lrt per min, I thought that was going to be adequate...it wasn't.
The finger is slowly being pointed at the HE, from my point of view.
I'm thinking aloud, but maybe the 4ltr HE volume is too gr8 too allow for quick heat transfer!
What do you think 7

Well, mine is 2l which works beautifully. I don't think you'll have a problem with a 4l HE maintaining a constant temperature. It will be slower to react to changes in set temperature though.
I got some questions...
When you say "thermal efficiency" what do you mean?
What temperature is the water in the mash tun you are trying to run through the heat exchanger?
Are you starting with cold water and using the heat exchanger to heat it to mash temps?
