just bought 1 few week ago.. with pump very noisy.. somemore causing RM500++ and the salesperson saying the heater is silence one.. and new one.. just release.. the noise sound is loud like i m cutting a tree from my house.. feel like being cheated.. and when they had send 2 alpha guys to check on it.. and they say is NORMAL!!! i am going to call the alpha service centre today.. if they are not giving me a good reply.. i m going to post the video of the heater and complaint to consumer department already..

hrm.. the water control already put at max level.. or are u suggest that to remove it completely? i really wish the noise can be reduce... kind of heart pain seeing the product is not up to our expectation after spending so much.. being mislead by the sales person.. Alpha technician saying the silence model will only release in Mar 2011..
