Most likely, a (missing or installed) bypass valve is not the cause for this problem. If that pump is really the warm water circulation pump, sometimes users permanently switch off that pump in order to reduce the huge losses which are caused by recirculation.
How does the Grundfos bypass valve work?
Quote from Youtube video: When it begins to cool the pump activates the valve opens. And water is pushed back to the water heater through the cold water line until the hot water line is back up to temperature.
How do I install a Grundfos circulating pump?
Quote from the video:
Quote from Youtube video: Be sure that the pump doesn't touch the exhaust vent pipe of a gas or oil fired water heater. Then we'll tighten down the dielectric fitting with a wrench.
Do hot water recirculating pumps run continuously?
While the system is capable of running continuously, it doesn’t always do this. Most hot water recirculating pumps come with sensors or timers to regulate operation. Sensors can detect the temperature of the hot water in the pipe, only running the recirculation pump when the temperature drops below a specified level.
How does Grundfos Comfort pump work?
The Grundfos Comfort System is a hot water recirculation system. This series eliminates cold water line runoff at the faucet using a bypass valve and pump with a timer to control water flow while delivering instant hot water.
Does a recirculating pump need a return line?
Not every domestic hot water recirculation system requires a return line. For residential and light commercial applications, there is another way to save water and maintain hot water at the last fixture.
What does the Grundfos Comfort valve do?
Quote from the video:
Quote from Youtube video: System is designed to give homeowners the added comfort and convenience of instant hot water and reduce the amount of wasted water saving. Up to 16,000.
How does the Grundfos Alpha 2 work?
Quote from the video:
Quote from Youtube video: It does this automatically. And continuously over the life of a system providing maximum comfort with minimum energy usage by continually adjusting to the most efficient operating speed Auto adapt.
How does Grundfos auto adapt work?
Using its two temperature sensors, one built-in and one external, the pump is able to learn and adapt to the hot water consumption pattern of the household. This means that Grundfos COMFORT will start circulating hot water from a learned pattern just before you need it.
What is Grundfos auto adapt?
The Grundfos AUTOADAPT algorithm
In more technical terms, the objective of the AUTOADAPT algorithm is to measure and analyse the heating system during operation and adapt to current heating patterns. This is done by optimising the position of the proportional pressure curve via a three-step process. Start.
How do I change the speed on my Grundfos pump?
Quote from the video:
Quote from Youtube video: And as you can see the speed setting here is red dial. And once again little three dashes. One two and three usually set to the middle of setting. Just tweak it up to three there.
What setting should my Grundfos pump be?
proportional pressure setting
The pump should be set to the proportional pressure setting where the differential pressure adjusts proportionally to the required flow in the system.
What setting should my circulating pump be?
Quote from the video:
Quote from Youtube video: So the usual. Setting is to stick it in the middle in the number two medium saying and leave it and probably up into such guilty over the years of just setting it there and away you go.
Should my Grundfos pump be hot?
The most likely cause of this problem is that the shaft or propeller on the pump is stuck. On some occasions (especially when the motor is extremely hot), the pump’s motor is the problem. The pump will get warm, but it shouldn’t be hot to the touch.
How long do Grundfos pumps last?
The pump of your central heating system can last a long time if it is properly installed and maintained. Typically, they keep going for at least 10 years.
Do circulator pumps run all the time?
The effects of an always-on circulator assembly installation are more even heat and in some cases perhaps improved freeze-resistance for the heating system piping. So depending on where you live and how your heating system is designed and controlled, it may be normal for the circulator pump(s) to run continuously.
