High volume water heating

You cannot maintain the water at 36°

Sorry this in not constructive. I can maintain water at 36 degrees. I just would like some leads to the most affordable methods. Just regarding heat not water condition.

It wasn't meant to be non-constructive. You just seem to be ignoring the Point about storing water at this temperature, there are perfectly legitimate reasons why we are pointing it out Perhaps if you explain a little more what you actually need the water for ie end user, you say for a spa but that could be anything. Anyway I'm out!!

Spa bath/hot pool/hot tub. Hot, treated water to bath in. I'm not ignoring the need to manage the water condition but I'm not here for water treatment advice. Just solely the method of heating bathable water.

To be fair he has & stated that the water will be treated so < 60 is not an issue.
OP
Go speak to Andrews Water Heaters Technical they are the only ones who will be able to answer your questions.
You must tell them what the water will be treated with !!! these units have copper heat exchangers but you may need something like a swimming pool boiler, to be able to handle the chemicals.

Why not keep the water in the spa, why send it back to the holding tank ?

It's not water treatment. If you store water below 60°c you exponentially increase the risk of developing legionella contagions.

Store the water at 60°c or above. Provide a thermostatic mixer valve at each spa to give you your 36° or whatever it is you want.

I want to be able to wipe down the bath after every use as well as well as having one large combined treatment system. Holding the water in a sealed insulated tank I feel would be the best way to reduce heat lost during downtime and overnight. I dread the thought of constantly putting covers on and off the individual baths. But I will have to consider the setup costs against the running costs as well.

I don't understand croppie, can you explain, what is not water treatment ?

You must have very dirt clients thats all I can say !!!:wilted_rose:

Heating 80 litres X 9 Degrees C in 1 minute will require 50Kw off heat output. Allowing for efficiency and other heat losses your system needs a boiler/water heater rated at 60Kw min.
