If you mean Smoother, once I got past all the smooth talk, it seems to be basically a delayed-off relay. Some Taco relay boxes also have an (overpriced) time delay option.

Of course, running the pumps after the heat has gone off is certainly a Good Thing.

It reminded me

of gravity hot water heating.

Well, it's still forced circulation. Instead of circulating all the time, they want to run the circulator for a little while after each heat call ends, and then shut it off. Presumably the device contains a delayed-off relay (~$20) and some wiring, being sold for several hundred dollars.

They say running the circulator a little longer will result in more even heat, but is cheaper than running the circ all the time. It is true that when people check for savings they look at their gas meter but they don't account for electricity usage, which is higher with constant circulation.

Well, I have three circs, together they draw maybe 2 amps. Over one day that's 5 KWH, or 50 cents. Bang-bang operation would run the circ maybe one-third as long, averaged over the heating season. So I'm paying ballpark 30 cents more a day or $9/month for continuous circulation, over our 8-month heating season that's $70.

My heating bill is about $1500, so we're talking about 5% on top of that, or about half of what someone would save going from a 80% to a 90% boiler.

I'm not advocating buying this device, but wetheads tend to ignore electricity costs...
