smart circ application question

CC.Rob_4

Something hot rod mentioned in another thread regarding adding a smart circ to an existing simple system has me wondering. What, if any, applications and benefits will there be for the new "smart circs" (defined as say low power consumption, delta-P) in an existing typical 2-3 zone residential system? Say there's a standard CI boiler, or maybe something piped primary-secondary, not necessarily a mod-con.

Thanks.

motor efficiency and following the system curve

are the two big reasons.

Typical wet rotor circs run around mid 20% efficiency. IF they are running on the sweet spot of their curve. Few are when 1 baseboard zone, for example, has it's own 80 watt circ In that condition it may be down around a 12- 15% wire to water efficiency!

The ability of the circ to know and respond to opening and closing zone valves, or TRV for example. Or program it to watch and maintain a certain delta t through a heat exchanger or boiler.

Consider solar where the circ adjusts to the ever changing solar gain, and uses the very least amount of electrical energy to harvest the solar. No more bang/ bang pump operation based on panel to tank differential.

The ability to monitor the circ via phone lines or cell phones has a lot of eyebrows rising.

Just the thought of 10 million circs being upgraded over the years to consume half, or less power is a strong incentive.

My panel radiator demo compared output difference via an infrared camera with a 17 watt circ and a 80 watt circ. very little "view-able" or "feel-able" heat output at less than 1/4 the power consumption.

will boiler makers

be on the band wagon to start specifying these low power circs?

I am thinking about the recent Knight news that a 26-99 is required for the boiler loop. On small residential installs, the electrical usage is a factor to consider. (for those of us going from a single circ 007 with a few zone valves to a p/s setup).

I hear that the Wilo Stratus will be available by fall or so.

It would be nice to be able to use these leading edge pumps on leading edge heating equipment!
