  • Compact Under Sink Heater, But Watch Electrical Requirements
Model: YF003-3000W
This is a small, single unit electric tankless water heater designed for one sink. It’s interesting that it comes with a remote, which lets you turn it on or off without crawling under the sink. The digital display is clear, but since it’s tucked under the sink, you don’t really see it during regular use. One very important consideration is the electrical requirement: it lists an 80-amp circuit. Typical household outlets are only rated for 15–20 amps, so you will need a licensed electrician to run a dedicated line capable of supporting this unit. Honestly, 80 amps seems excessive for a small under sink unit, this is the kind of capacity usually reserved for larger units or systems powering multiple heaters. The remote might be handy in an RV or a setup where the sink isn’t used frequently, but in a standard home kitchen or bathroom, it’s less useful. Overall, the unit is compact and functional, but the high electrical requirements make installation more complicated than it might appear at first glance. ... show more

  • Solid Water Heater for Small Spaces 💧⚡ Solid Water Heater for Small Spaces 💧⚡
Model: YF003-3000W
TL;DR: Reliable 3000W tankless water heater with a standard plug that actually only needs a 30-amp circuit. I have inspected this Aottop tankless water heater a good bit. It appears to be made of high quality materials and the value is good. Supposedly, it reaches 99% thermal efficiency. It appears to be a high quality water heater. Just a few things to know. The description says an 80-amp circuit is needed. But you really just need a 30-amp, as that would be needed for a 3000W device like this. I messaged the seller and they confirmed 30-amp is fine. So you will still likely need to get a new line run because standard outlets are just 20-amp. Another thing is the listing said it does not come with a power plug and requires professional hardwiring, but that is not true. It comes with a standard 3-prong plug, so no hardwiring needed. You just need a 30-amp outlet wired. My heater came with a black cord instead of white, but everything else was as described. It hits 131°F (55°C) in seconds. If it actually needed 80 amps, it would be powerful enough for a large tankless whole house water heater or multi-vehicle EV chargers. Make sure your water pressure is consistent for the best results 🛠️🚿 ... show more
