Question ishow close is too close to put a light fixture next to the smoke detector? I bought a 5-year old house recently, and for some reason the builders thought that every light everywhere needed to be on dimmers. If the capacitor were very large, or some kind of regulation were present in the circuit, this would not happen, but that would be much more expensive so you don't see it in cheap products. It's an older house built in the late 1940's. AFAIK those heaters are pretty simple and cycle elements on/off to maintain temp instead of using a faster PWM - no way around the source of the problem - maybe a tank heater?

A typical LED bulb is made of ~3v diodes arranged in series hooked up to a rectifier and a current limiting element (either a capacitor/resistor as in this diagram or more commonly in the USA a linear regulator on the DC side): In this design the LEDs are stacked up to be close to the rectified mains voltage so that losses are low in the resistor/regulator. Once we turned on the water heater all the new high hats started to flash. The only way for tankless is NG or propane. Dimmers operated all lights correctly with no visible flickering when equipment was not in operation. Any help would be appreciated. Lighting on its own original circuit coming from the main panel. The only way to know what the problem is, use a voltmeter and measure the voltage on both sides of you load center while the water heater is in operation. LED circuits can be designed to reduce flicker by adding capacitance and using a full bridge rectifier or inverter to convert AC to DC, but cheap Christmas light strings may not use a full bridge rectifier, which would cause flicker at around 50/60 Hz.
