Question Add on for new boiler

I have a year old Bryant Boiler.
At the annual checkup, I mentioned the gas fired up very frequently.
My dealer said it was a "stock" unit and there is something he can
install that makes the pump keep pumping even when the gas is not
fired up.
It would save gas.
He said I would probably set my thermostat lower as sometimes it
overheats with this unit.

Does any of this make sense.
He quoted around $350 to put this on.
I don't remember what he called it.

Any opinions? Is it a lot more efficient?
Any disadvantages?

Boiler cycling

Frequent cycling is often an indication of the equipment being oversized for the load on it. If the device he was talking about is an "outdoor reset", they definately do save on energy cost because they match the boiler temperature to the outdoor temperature. In other words, the colder it is outside, the more heat your house needs thus the boiler operates at a higher temperature than when the outdoor temps are not so cold.

Question not sure it was an outdoor reset

I don't think he called it an "outdoor reset."
I doubt my boiler is larger than I need.
The conversation came about when I said I heard the burners go on once in a while and then shut off very soon. Maybe a minute.
I wasn't sure if the pump actually even started pumping.
He indicated that the furnace was keeping the water at a certain temperature.

I guess it would be like my water heater. It fires up to keep the temp at a certain degree but I'm not necessarily taking any hot water out of it at the time.

Whatever my dealer would like to put on I think keeps the pump going even if the gas is not fired up.
Right now my pump apparently only pumps when the gas is fired up.

I wish I could be more articulate but I barely know how boilers work.

I doubt your boiler maintains a constant temperature if you have a separate water heater. If it does, your service person can change that pretty easilly. Was the device he was talking about possibly called a "Heat Manager"?
