Lasko MODEL 5620 Review

I received this Lasko Model 5620 Silent Room Heater as a replacement for a recalled oil filled heater.  I had no idea this could heat a room as efficiently and quickly as the oil filled heater.  Wow!  Was I in for a surprise.  Not only is it thermostatically adjustable but it is also programmable in one hour increments from 1 to 8 hours or can be set to run continuosly.  It has performed so perfectly that we no longer use our central heating but use a second Model 5620 in our bedroom.  I plan to order three more and completely eliminate our central heating system which sucks up electricity at an unacceptable rate.
