| First and foremost you should look into variable speed pumps in place of the Trisar. In Canada they have actually stopped the tristar pump series completely in favor of the new generation variable speed models. They really are worth the money. If you decide to zone in a 3 zone bypass on your heater as suggested above to limit the water running through the heater, be sure to look into the requirement for a pressure release valve to be installed. In my area no bypass = no PRV however as soon as you add a bypass valve then a PRV becomes required by code. A 400,000 btu heater is more than enough for your pool and hot tub requirements. Maybe even a little less however with this style of installation the tub stays at pool temps until you call for heat at which time you are looking at about 20-30 minutes to get the spa up to 104. I did not see any valve actuators on your list - they might be included with your goldline panel but be sure as you will need them. Seriously though think about the variable speed pumps. Both Hayward and Pentair offer one now but order early. Last year the Eco-star model was on backorder for almost the entire summer. They are also the quietest pool pumps that I have ever heard.
