By secondary aquastat I presume you mean a secondary high limit. It is required on all commercial buildings but codes vary by location on residential applications. You need to check with your local code officials. As a rule, the more safety devices the better.

Thanks Grady.. yes I was talking about the secondary high limit. Someone told me that is is a must and that is why I asked. I think I will add one since it is a safety device.

How about a low water cut-off. I do not have any heat distributors installed below HW boiler. Should I install one anyway just to be on the safeside?

Low water cut-off

A low water cut-off is always a good idea. It can save a boiler from dry firing or excessive fresh water feeding. When a LWCO is installed, you should shut off the feed water. If the LWCO trips, you know you have a leak.
