How to efficiently use my Prestige Solo 110 NG Boiler
 
I have been reading a lot on how to achieve max efficiency from my new boiler. I have an outdoor reset installed, and the settings are as follows:

Coldest day: 10*
Minimum Setpoint: 100*
Max setpoint: 180*

My house has cast-iron radiators.

Normally, with my old oil boiler, i kept the house at 70* during the day, and setback to 60* at night. I am willing to change if it would save money.

I have been reading that using lower boiler water temp, smaller setbacks (maybe setback to 66* at night) so that the circulator is more consistently running increases efficiency.

How do I figure out the most efficient way to heat the house? Thanks.

With cast iron rads. You shouldn't need more then 160 water temp. Many houses get away with 140. All depends on how much radiation your house has in it.

10 degrre setback is fine. As long as you don't want quick recovery.

So is it better to have 10 degree setback and set the thermostat to come back up to 70 like 3 hours before-hand so it recovers in time, or should I just use a smaller setback? Which is more efficient?

Similarly, is it better to use lower temp water and set the thermostat to recover earlier, or use higher temp water and have the recovery time be shorter?

Use a thermostat with intelligent recovery. that way it will start to recover when it needs to. Weather it be 30 minutes, or 3 hours.

using higher temp water, waste more fuel. It doesn't save any money.

My t-stat does have a smart-recovery option. I tried it, and it didn't seem to work. Does it take a few days to learn?

Yes. it can take 7 or more days for it to learn your house.
