suggest you buy 2.
1st one - an oil radiate heater, any brand ok as long as safety is good. this can be switched on for long time and no need to worry.
2nd one - fan heater for temporary and instant warming especially useful for taking bath for bb, buy rowenta SO9030 cos this is the only brand / model on the market that has 防水氣設計 function ie. it can be used in the bathroom without worrying it gets wet and cause safety issue. http://www.wingonet.com/product/ ... p;prod_name=ROWENTA Ceramic Fan Heater SO-9030
