is this for hot water circulating pump or not for hot water?

Yes. Designed specifically for circulating heated water in hydronic heating systems.

yes this circulator pump is mounted on the side of my hot water boiler for baseboard heat

This pump is designed to circulate hot water through your plumbing. Blend your water at the spigot between hot and cold valves to achieve desired temperature of water at the tap. Or if you saying your hot water side it too hot and may result in someone being scalded all hot water tanks have temperature controls. I keep mine set at 120 which I think I read takes 5 minutes to scald a person. That is probably lower than a lot of people set their hot water tank temp but is plenty hot and safe at the same time.

I use this one in my kitchen sink for cold drinking water, I don't think it can be used for hot water as well. You may call or contact 3M first before you buy it! Good luck!!

As many as you need. We have four separate hot water lines in our home. It is best to install the comfort line on the furthest faucet in each line so that each faucet has hot water flowing to it. The Grundfoss pump on the hot water tank is set to supply hot water from 6:am to 7:30am and 6pm to 7:30pm.It saves a lots of water from going to waste and saves dollars.

I used it on a water cooler, to pump water into a holding tank, but found the pressure was very low, I really don't know as to your application, but if your need a good flow, this is not the pump, for you.

I have two of these pumps. Both are used to circulate hot water in a boiler operated RV heating system. Both are very quiet.

It has to be installed near and piped to a duct. It will not work with a hot water heating system.

yes, It is working fine for me. tun the power off before connecting. suitable for small pumps for house circulating pumps. I hope this helped.

Yes. this is normal. Because you are pushing the water from the hot water side to the cold water side. The valve will stop the flow of water from the hot to cold water side at a certain threshold temperature. And this temperature is somewhere on the warm side. Therefore the cold water side will be warmer than expected and you will have to run the cold water side until you get the water to the cooler temperature that you want. This is one of the drawbacks of this type of system. It cannot be helped. It's basically a compromise based on the need to get hot water faster. The only way you will truly get the instant hot water and cold water is to set up your plumbing system whereby the entire hot water supply line daisy chains all your fixtures such that the last fixture has a hot water return line running all the way back to the water heater. But this will cost you money to have a plumber do that. This hot water recirculating system is a compromise to save costs.

The water does run from the hot water pipe into the cold water pipe and back to the hot water heater. It works great. I have not noticed any hot water coming out the garden hose when the pump is on. This system was first recommended to me by a Hospital Building Superintendant which uses a commercial version of this same system. I highly recommend installing this product to save water and get hot water when you need it.

yes. that's exactly what i used it for. we have circulating hot water for heat and that's what i covered.

I have one that I installed myself a month ago and so far I haven't had any problems. I'm most pleased with the circulation pump. No waiting for hot water.

Yes. As long as you have a return line running back to your water heater. You do not need a separate return line at every faucet. You need one return line. Follow your hot water pipe to the end (last branch takeoff), cut in a tee and run pex or copper. At the bottom of your tank style water heater there is a small, usually plastic valve. Remove that valve and screw in a 3/4" brass or stainless pipe nipple. Then install a tee inline with side outlet looking up and in the end of the tee put a brass drain valve to replace the crappy plastic one if applicable. The side connection on the tee you installed is where you will connect your return line you just ran. I did not notice if this pump had a built in check valve but if not you may want one to prevent water from flowing through both the hot water main and the hot water return to the faucet nearest the end. Water will follow the path of least resistance so the last branch on the main usually ends up being similar in distance to the water heater from either line. As a result water can back feed up the return line and will bring the cold water entering the tank with it. This is especially true when a second source of hot water is being used at the same time hence the need for a check valve.

I have both single and double valve faucets and it works well for me. Be aware there has to be a return pipe from the plumbing point furthest from the pump. It is not one of those 'passive' systems that recycle water back down the cold water pipe. I found it to be a real quality product.Mark

Not sure how this regulator would function in hot water. It is designed to regulate water pressure at the inlet (cold side). Regulating the pressure after the hot water heater may place high (unregulated) pressure on the heat tubes, especially if corrosion is present.

That's incorrect. I take hot showers all the time. The filter on your kitchen faucet, ie PUR, is not for hot water. The shower filter is made for showers and there for all temperatures.

Hi, yest it's both for hot an cold. Note that the install is not standard as it has european fittings and will need an adapter to go from the faucet and couple to the feed hoses. It's also very heavry so needs to be mounted to a very solid sink.
