When you had mentioned Ridged and loss of power, it reminded me to mention they also have the 24V line.But the thing is, if you lose power at home you can use that battery to power your gas valve to heat your home.
Keep in mind you'll have to  manually open the zone valves,if you have circ pumps...well your f-D!So forget it.to those who have the standard Taco's  or Honeywell  you can have a heating system that will be old style gravity fed system.
