gas water heater

Salam semua, Sapa kat sini ada guna gas water heater?.. Crita skit pendapat hangpa mcm mana?. Aku cadang nak pasang water heater. Nak pasang yg electric risau kena renjat time mandi. Nak pasang solar water heater.. mak aiii.. mahal sgt la plak. Paling murah pun dok ada dlm 6k!!! Huh tak mampu...
