In Canada, by a Canada law, have heard that all propane heaters must be the design that continues to make heat when the electricity is down. Is this really true?
Is not the case in USA or in NH, and you can get either a propane warm air space heater that continues to work when the electricity is down or goes out until the electricity comes back on ...... which can make a big difference if the power is out for 24-hours in very cold temps. The non electricity dependent propane heaters operate on the propane pressure within the propane storage tank, and have a pilot light and a 12-volt dc Piezo (whatever that is?) self-generating hot air heat that can work a remote wall mounted thermostat.
It has a propane pilot light, which is the key design to the non electricity dependent systems.
A Rinnai direct vent will shut off without electricity, and come back on, when the electricity is back.
