1 inch pipe is .730 ID +/- (36 feet/gallon)
1.5 inch pipe is 1.28 ID (12 f/g)
2 inch pipe is 1.65 ID (7 f/g)

The numbers may be off for your particular pipe, but the point is that as far as volume it take 4.5 each of 1 inch pipes to eqaul one 2 inch or 3 each - I inch pipes to equal the volume of a 1.5 inch pipe. When including friction losses one might up it a pipe or two.

I have not built or bought a system yet,

?? Higher flow rates should have better heat transfer efficiency albeit with some diminishing returns.

I am about to construct a pool in Spain... and all of you might say I dont need a heather and your right ...but my wife does so I am exploring the possibility of building my own..
But before I go into the requirement for the tubes and size and all that I want to know is if anyone has ever built a pool from scratch and if so was insulation ever considered... I am considering installing 2" polistyreen foam before the concrete goes on... All pools are constructed of cement here... to prevent the loss of heat through the soil...

The other thing that has me a bit baffeled is that most of you have cut into your pump inlet/outlet to install the heather but since I am building I would like to install independent piping for the sole use of the heather. I am also installing a solar powered pump to move the water in the pipes, so should I take the cold water from the bottom and put the hot in at the top or in the middle both or the cold at the top and the hot at the bottom...

Thank you

Trust me, the century old pool industry already has their "pup in the group".
It may be developing new plaster materials, etc., but the basics are given and well justified. Trying to come up with a better or improved mousetrap can only end up in a very costly disaster.
Just to understand, 20 000 gallons of water represent about 80 metric tons. Add 30 cubic yards of concrete to that and picture how the styrofoam will react to it.
The pool shell will settle before you even apply plaster. And of course you will loose all the connecting plumbing. There is a silver lining . You will save the cost of plaster and filling the pool, since you by then realize how stupid this idea was. :wave:
