I am shopping for a heat pump + need recomendations

[waterbear]

Two questions I have is about the dual pool spa set ups. Are there 2 inputs and 2 outputs, or do you vlave off the plumbing so you will heat the spa and pool at different times?

There is one intake and output. In most pool spa combos that share a pump/filter/heater valves are used to select the pool or the spa. Automation is wonderful here!

(Don't hot tubs have their own heater?
Portable spas ususally do. Ones that are built in with a pool might and also have their own pump and filter or they might share this equipment with the pool. In a shared system the dual thermostats allow to you select different temps for the pool and the spa
I don't have one now, but thats the next purchase) And secondly, should I set up a bypass valve so I can run water back to the pool without running it through the heatpump when the water is warm?
Mine wasn't plumbed that way. When the water is warm the heatpump just doesn't come on but the water flows through it. Downside to a bypass valve, IMHO, is that during the summer you might leave it bypassed for months and stagnent water will stay inside the heatpump.
Thanks again. (If all goes well I'll be placing the order this tuesday and installing the unit next week.)

Hope this helps.

I think a titanium heat exchanger is better than a copper one.

Thanks for all your help. i am getting ready to jump into the next phase. I will order the heat pump in the next day or so and I am trying to decide now about building the new manifold. I plan on getting a new chlorinator and multiport since bothe these items are now 10 years old. I will be checking out local contractors to see what thier price and availability are. I'll let you know how its going.

which heat pump did you decide on, and why? I am looking to purchase in the next couple days. Thanks.

The hayward heatpro 21002. I believe I got a good price from poolhub, hayward is a large manufacturer of pool stuff so there should be a large network of repair facilities available. There is no water chemistry exclusion in the warranty. And I got the dual thermostat in case I get the hot tub. What are you looking at and why?

Leaning toward the Jandy AE2500 from here http://www.poolheatpumps.com/Heat%20...ice%20List.htm. Seems to have all the right parts. I am still digging in, but I was also looking at the Heat Siphon. I am probably going to give them a call tomorrow and have them help me decide as it is really down to just pulling the trigger. I will update after I have talked with them.

I have the Heat Siphon and am very happy with it. I don't have a spa.

I just put in a Jandy AE2000 and love it so far - wiring was a snap, plumbing as well (just 2" fittings, unions included).

I got my first estimate on the 220 line today. He has to run 15 feet from my circuit breaker box, drill through the house and mount a service disconnect on the outside of the house. To be honest I couldn't believe the number they came up with. $1200. There will be other estimates.
