Hello, I'll soon get a heat pump heater installed. I have an 8' x 10' utility shed beside the fresh water pool that contains the filter and all gear. The filter is along a wall and the heater will be right on the other side of the wall. There will be about a 4' run between the filter, through the wall and to the heater. I understand you can choose not to install a bypass initially, but rather do it only if and when a situation arises wherein I need to run the filter without water passing through the pump. If so, should the initial plumbing be planned to be able to add the bypass configuration inside or outside the building?
 
If you're installing a HP, install the external bypass at the same time. The only unique parts needed are a 3-way diverter and a check valve. Get high quality components (Jandy or Pentair). It doesn't really matter whether it's inside or outside, do what's more practical. Having the bypass will make your system much more efficient when the HP isn't in use.

General question about pool heat pump programming coordination with programmable filter pump. I do not have what I think is called an automation system. My filter pump is programmed to start at 8 am. Do I complete all the basic programming on the heat pump but ignore options for start time, and it starts on its own when the filter pump starts?
