I turn it on, then hot water gets to it, it turns off automatically, will it turn on automatically again when the water gets cold while Im showering?

We have the pump installed, and it works well. The pump only starts when we push the button connected to the unit, or when we push the button on the remote control. When the water temperature is reached, the unit stays off until the button is pushed again.

No. The pump only circulates cold water out of the hot water pipes and into the cold water pipes. If your shower goes cold, your hot water tank ran out of hot water and circulating the water further isn't going to make it hot again. If you keep pressing the circulate button after all of the cold water has been circulated out of the hot water pipes (and there is still lots of hot water in the tank), the pump will run for about 30 seconds each time the button is pressed. And if you press the button enough times, your cold water pipes become full of hot water. You then have the opposite problem-- hot water comes out of your cold water outlets and you waste water running it to cool down.

No, when the hot water gets to the temp sensor in the Metlund, it shuts off. You should have the same temperature water in your supply line as in the recirc. line, so you don't need the recirc pump to keep operating. The supply line is sending the same temp hot water to your plumbing fixtures (shower, tub, sink, etc.) The cool water you're sensing in the shower or tub is the cold water in the line that builds up when you start your water flow in the supply line after being off for a period of time.

The answer is no. The pump comes on to pump water from the hot water line to the cold water line until the water in the hot water line reaches approximately 105 deg. At that point the pump shuts off, and the cross connect valve closes. If you are showering and the water starts getting cold it means that the hot water in your tank is running out and the pump cannot help that. The pump produces no heat and can do nothing about that.

I would think not as the temp sensor in the unit only senses the water coming into it, as in it has brought hot water from the heater to that location, then when you turn on the shower that should keep the hot water coming to that location. The pump does not bring more hot water after it has reached temperature, the water use should keep the water hot. If you shut the water use off, such as shutting off the water in the shower, then you can, after a period of the water cooling off, restart the unit to bring hot water back down the line. I am not sure I was clear on answering your question, maybe someone else can be clearer.

Once the water boils, it automatically switches to warm mode. In warm mode, the water continues to be just at or very close to boiling temperature. Actually you would have to switch it off if you want it to stop.

I cannot confirm this, but the water at the faucett turns from cold to hot in about the same time as when I was using a tank heater. Hope this helps.

Yes. I leave mine on at night and it automatically shuts off then the water is low on any setting.

No it wont feel warm. It has an automatic thermostat that will only come on as needed to keep the water from freezing. I just replaced the one i bought 8 years ago. I hope this one , which is the same brand, lasts as long

On my shower it pulls out to turn on, rotates hot to cold, and pushes in for off.

yes, it is well insulated and does not turn on and off constantly. I used to look under the sink frequently to see if it was on or not and rarely do I see it on unless I have just used a lot of hot water.

No, the button makes a click sound and automatically turns itself off once the water is boiling. If you forget about it and come back too much later, the water will be cold again.

I had the same concern but it has worked fine. Refreshing, comes to mind. And as I thought about it I came to fear a burst of too hot water more than cold. I've not used the warm/cold model but I don't think there would be a lot of difference in that when you turn a hot faucet on it takes a while before it is hot.

water pressure automatically turns it on, with no battery required. its like a mini water turbine generator. Water goes on, so does the product. Water pressure turned off, so is device. Inside there are some type of sensors that change the L.E.D. colors depending on whether the water is cold, warm, or hot. This aspect of the device is not too accurate, so just enjoy the flickering light show.

When you first turn the irrigator on the water is cold for a few seconds. Then it reaches the same temperature as the shower and remains at that temperature until you turn it off.

I have not had any issue with using it in cold water. I switch off between warm and cold.

Not at all. It only turns on when the water temp drops below a certain temp to keep it from freezing

Then the water heater doesn't automatically come on. But you can turn it on manually at any time.

The water is room temperature when you first turn it on, but after a few seconds the water becomes very warm. It cycles through your warm tap. It should not be a problem in the winter. We have had one for a year then added them to our whole house. Have not had any complaints in the winter as far as temp. Again it becomes very warm water with in seconds.

If you leave the light on then the power is going thru the unit and the heater coils will heat the water up to temp in say 10 mins or so and you could then "take your shower" ........................... if you forget to go shut it off it will continue to keep the water at the set temp and cost a lot to maintain that temp.Really if you take a shower everday at say 6am then just put the timers on to have the heater come on for 30 mins starting at 5:30am and when you hop in it will be all hot for you and you don't have to mess with it again, it will shut off at 6am and you will have hot water most of the day ...................... the main reason for buying one of these is so you don't have to mess with it???

you just turn on, first you get cold water with low presure, after you turning continiously, you can get warmer water with high presure when hot water pouring into faucet
