I love this heater.  I bought this while living in a rental unit with an old inefficient furnace using ridiculously expense oil.  We switched to using this in whatever room we were in, and it cut our bills dramatically.  It heats up a room very quickly.  The cats jump on top of it and it's not a worry because it's cool.  I do wish the wheels would lock though.  I ended up putting something under the wheels so that when the cats did jump on it, there was no risk of them moving it and accidentally pointing it at something flammable.

Powerful, quiet, pet safe
wheels don't lock
