Does this heater have a built-in pressure switch that prevents operation when there is no water flowing?

It is a separate piece that comes with it. It depends how you hook it up to the timer you use if it's not hooked up right it will burn out.

Yes, it shuts the unit down when water pressure drops. We used it for a pool and when the filter cartridge plugged up and decreased the water flow it shut down, great reminder to change cartridges...

I have never tried it, but the switch has on (no timer), timed and off. I usually just let the water run until it's hot enough.

no --if it rains much the bottom of the door will have water standing in it. i have had to return several because it causes the switch to not come back on.

Yes, The on-off switch is as depicted in the image. I do not use this switch because I have a remote in-line switch in my hook-up but I would have no problem with using the pump-mounted switch. And, yes, as another reviewer stated, the pump does have a pressure switch.

No, but it is a great little heater. Very light weight & portable. If you pick it up, it automatically turns off, so it's great around kids & pets. It's just a personal heater.

yes, on the back of the unit is an on/off switch for hot water and an on/off switch for cold water. I believe the one for the hot water is a red switch.

Yes this pump has a pressure switch and will begin pumping when faucet is turned on and then stops when turned off.

No. Turn on the power switch and go. Automatically shuts off when water tank runs dry.

Not that I know of. Check the air flow for the heater if there is an obstruction.

No. The on off switch is on the part that is lowered into the water. best way to stop flow is just to lift it out of the water- it doe not appear to be damaged if it runs w/out water in it for a little bit. My guess is that was no on/off switch at the top to increase reliability and reduce the cost of the device.

No it does not. Additionally, after you shut off the water flow in automatically reverts back to stream.

No, it only shuts off the water when it reaches a certain temp. It's not an on/off switch. You'll need to get a shower head that does that.

No. It only has a line in, power button, and drain plug for the hot water tank.

No but if you turn down the pressure of either the cold or hot connection the water will go down and not as fast

Unfortunately, no, it does not. I have accidentally shut the light switch that this is powered to and it will not come back on when I turn the switch back on. You have to turn it back on and reset the temperature BUT it is still a great heater. I have it in my son's room and it really keeps the temp steady at 70 degrees. And setting the temp is very easy. Hope this helps!

Yes, there is a ball float inside that turns the unit off automatically when it reaches the "off" water level.

This is an off-on Valve. It can control the flow rate I am sure, but not pressure.
