I am building a 1150 sq. ft. slab on grade cabin. I am going to install in floor heat. One zone 5 circuits using a takagi tk-jr boiler. Ive seen three systems, primary secondary (two pumps) -A system using one pump, and a system using one pump with a mixing valve. Which is best for my application?

Is this one big area, or are there several smaller rooms? If it's only one area, you can probably get just one of our Zone Pump panels. You can get it with or without actuators, so really you could have five "subzones" off the zone that is the manifold. If you need to mix down your boiler water, we also have a Zone Mix Pump panel, which should be able to do this. The pump on these panels can only do 10 feet of head at 10 gpm, but your area is small enough that this shouldn't matter. You can take a look at these in our catalog, here.
Thanks for you response, it will have two bedrooms, utility room, 1 bath. and open living room kitchen area. I am trying to keep it as simple as possible. I was going to use a 5 circuit manifold with 275' loop lengths. What should the gpm be for each loop?

If you are looking for simplicity, then I would certainly go with one of the Z panels. That way you don't have to worry about too much in your mechanical room, since the panel has the pump to pull directly from your supply if you want. Without doing a heat loss I don't really know what the gpm per circuit would be, but I don't imagine it would be too much.
