Hydronic Floor pump frequency vs water supply temp?

I definitely want radiant floor heat even at an added expense(if any) because I already have designed for a high mass concrete floor for passive solar storage and really like the evenness of radiant heat. MikeS, if I understand you prefer a holding tank approach to feed floor. I have found a dual xfer loop tank w/ elec back up that, though a little money, would let me off peak heat w/elec and let me add at least two other backup heat sources(wood, solar, DIY geotherm) if wanted/needed with just one tank. Does that seem reasonable? "Over heating" of our core winter living space in not an issue as over 1/3 of total space is 3 season and excess heat is easily distributed to that space and then usable in those times. Making a solar designed space that is zero net 70-80% of the time(at least for heat) is doable without great complexity. So my design for retirement home is a winter core space that can be lived in and heated for comfort for those cold periods. Also work for the few days/nights summer cooling is needed in my area. But it is true that the advances in energy conserving building techniques/design haven't followed thru to the concern for cost/energy saving heat/cooling plants to match them in the US. Being "green" shouldn't always have to cost more.
