Softside Hardside Water Bed Heater, 240W Digital Display Smart Water Bed Heater, Safe and Durable Water Bed Heater, Sensitive control, For King, Queen, Full and Twin

works well. my previous waterbed heater died. this one works very well on my california king waterbed.

This is perhaps the most underachieving heater I have ever seen. Even after three weeks it still has not gotten my queen size waterbed fully up to the set point temperature (30*). This is with a padded mattress cover, waterbed sheets and a heavy comforter covering the bed.The other problem is that it reads out only in centigrade, and cannot be set the fahrenheit at all, so I have to convert to set and read it.

It arrived just before the seller's expected delivery date range. I had to partially drain the bed in order to install it under the King Size mattress, and of course refilled the mattress. It is set to 28 C, which reads 88 F between the sheets with my infrared thermometer. It took several days to get the bed up to temperature, but I am thrilled to be sleeping in a warm bed again!

so far the heater is working, but it is in Celcius not Farenhiet

The controller does not have capability to fasten to hard side bed. But it works really good otherwise.

Taking forever to heat the bed back up. Seems to be suck at 30C Need at least 35.

The heater is longer than the original and the control is very nice. The only draw back ic the control is in centigrade , a chart that loosely converts to farenhight . I am just old school.Delivery was ahead of the date scheduled.

Worse thing everBed is still so cold and has been in for 3 weeksIt is awful do not buy this product
