Ideally, the heater should have a dedicated circuit and breaker to prevent any light flickering at all. LEDs do not like dimmers. Website operating Learn more about Stack Overflow the company, and our products. Similarly, they could put fewer diodes in series resulting in more headroom between the forward voltage and the rectified line voltage (and more dissipated across the resistor/regulator), but this is a nonisolated design - everything is attached to mains voltage, so by regulation it cannot have any exposed metal heatsinking. If you try all of these, but still experience flickering lights, give us a call at 888-554-4732. The way you do anything is the way you do everything. Any help would be appreciated. Archived post.

From https://www.justanswer.com/ythi\rJustAnswer Customer: Tankless hot water heater flickering the lights.\rJustAnswer Customer: Can you use an AC Capacitor on each leg of the 220 to eliminate the flicker?\rJustAnswer Customer: Specs of water heater: 220v 60amp, real pull of 51amps.\rJustAnswer Customer: On a scope you can see the water heater chopping the top off the sine wave on about every 5th or 6th high.\rKevin: Licensed Electrical Contractor: Hello and welcome to Just Answer.\rKevin: Licensed Electrical Contractor: My name is * * I will be happy to assist you with your electrical question.\rKevin: Licensed Electrical Contractor: 1) Flickering lights is an indication of a loose wire connection, usually a hot wire.\rKevin: Licensed Electrical Contractor: Since the H2O heater resides on a separate circuit than the lighting, this suggests a loose hot phase connection either at the meter socket or at the lugs of the main breaker.\rKevin: Licensed Electrical Contractor: Lighting circuits are a separate circuit than the H2O heater.\rKevin: Licensed Electrical Contractor: The 2 hot phases for the service entrance conductors need to be checked for proper torquing.\rKevin: Licensed Electrical Contractor: Also double check the H2O branch circuit connections/terminations.\rKevin: Licensed Electrical Contractor: 2) Capacitors are only used to filter surges or clean up poor power quality in devices such as surge protectors and power quality monitoring systems.\rKevin: Licensed Electrical Contractor: A cap is not going to resolve the problem:) 3) On a properly wired 120 and/or 240 volt AC system, an oscilloscope should show a fairly clean sine wave.\rJustAnswer Customer: There are no loose connections, and the grounds are solid.\rJustAnswer Customer: Even installed a new ground for the meter base.\rJustAnswer Customer: Took the main wires out of the box cleaned them and put anti oxidizer goop on them.\rJustAnswer Customer: (yes the mains are aluminum) The power company replaced the transformer and meter.\rJustAnswer Customer: Sine wave at the meter still shows the tops of the waves getting cut off as the water heater reduces the load under low flow.\rJustAnswer Customer: If the water heater is under full load-no flicker.\rKevin: Licensed Electrical Contractor: Thanks for the replies.\rKevin: Licensed Electrical Contractor: 1) The only commonality that the H2O heater and the lighting circuit is the hot.\rKevin: Licensed Electrical Contractor: The H2O heater does not have a neutral, so that eliminates that possibility.\rKevin: Licensed Electrical Contractor: 2) Since the XFORMER and meter socket were recently replaced, the problem is either at the utility XFORMER or a loose hot phase termination at the meter can.\rKevin: Licensed Electrical Contractor: 3) I suggest to contact the local electrical utility and have them check their connections.\rKevin: Licensed Electrical Contractor: They can also install a power quality monitor at the meter can to confirm the cause of the problem if within their transformer.\rKevin: Licensed Electrical Contractor: 1) Poor incoming power quality such as a chopped sine wave and/or noise on the line is another indication of the hot wires not making proper contact or an issue with the transformer.\rKevin: Licensed Electrical Contractor: The LOAD side lug connections at the meter can be temporarily removed and the utility can place a scope or power quality monitoring device on the LINE side of the meter to confirm if the problem is the utility.\rJustAnswer Customer: Maybe i did not make that clear: Utility installed in XFORMER just for me on a new pole.\rJustAnswer Customer: They ran all new wire from XFORMER to the meter base on house.\rJustAnswer Customer: Utility says \"we have done all we can do.\" They had monitor on the meter side for a week.\" Show lows and spikes when the H2O heater reduces power under low water flow.\rJustAnswer Customer: Power coming from the XFORMER looks good.\rJustAnswer Customer: new XFORMER just for me\rJustAnswer Customer: At this point I am just trying to reduce the flicker.\rJustAnswer Customer: I switched to all LED lights, and that helped.\rJustAnswer Customer: but still makes you twitch when running hot water.\rKevin: Licensed Electrical Contractor: 1) Well, utility companies have been known to make mistakes.\rKevin: Licensed Electrical Contractor: Been down this road before:) 2) Your lighting system requires a neutral conductor for the 120 volt circuits, yet the H2O heater is a 240 volt circuit which does not require a neutral connection.\rKevin: Licensed Electrical Contractor: Flickering lights indicate a loose hot wire and dimming lights indicate a loose neutral wire.\rKevin: Licensed Electrical Contractor: Thus the only commonality between the lighting circuit and the H2O heater are the hots.
