I have just purchased a Heat Pump(HP) to try and extend the swim season here a little, I have a couple of questions as I will be doing the plumbing, then get the Sparky to wire it up.
Reading up it seems the SWCG still needs to be last in line, in the schematics there seems to be a bypass valve to cut out the HP, presumably this is as simple as 2 x T's with a valve between, is this just for bypass or for some sort of 'balancing' does all the water need to go through the HP all the time if its in use?
Would it make sense to put a one way valve before the SWCG now to prevent any backflow from the SWCG in to the HP, its a Titanium Heat Exchanger.
The most important question: The unit is approx. 1000mm x 500mm x 350mm I have an equipment shed approx. 2M x 2M x 1.5M clad in Slatted Timber with 5mm slat holes, there is plenty of ventilation in a normal sense, but would it be a daft idea to try and site the HP inside the shed or would that likely cause issues with the functionality of the HP. I'd rather not have it outside the shed if it is at all possible...
You can just see the shed at the end of the picture here (in construction) https://www.dropbox.com/s/uu5mguf53s..._1416.JPG?dl=0
Thanks for any advice.
