VVKB Engine Heater 110 Volts 1000w Titan-P5 with Thermostats and Built-in Water Pump TUV CE FCC ROHS

This unit heated up but did not circulate any water. I took it apart and the circulator motor was spinning but the impeller itself was much too small for the chamber that it was mounted in.DO NOT BUY!!!

Junk. It work for one year. This year it almost started a fire and the pump itself corroded tight and the unit started to leak. Poor assembly and poor design for the o-rings to hold a solid seal.
