    Excellent Replacement Gas Heater
    This new Rinnai gas heater is outstanding. It replaces our old 40 year old Rinnai heater that decided it was time to retire. It heats our large room super quickly and the thermostat control makes sure the room is always warm even on the coldest days. Would definitely recommend this heater.

    A great heater
    The heater has been very good so far, only had it since beginning of July. It heats the room really quickly and is very quiet. I haven't used the timer so can't comment on that.
