Choosing The Right 30 AMP Tankless Water Heater

A 30 amp tankless water heater is not the biggest in size, and they can’t supply hot water to a couple of water lines at a time. Otherwise, you must sacrifice their true water heating ability. Also, this unit is not portable, so you can’t make them like other outdoor tankless hot water heaters. It means you’ll use it regularly and it will have an impact on your electricity bill. That’s to find out the best energy efficient one.

Build Material

Yeah, build material is an issue; you may like glass, an alloy-made one, and steel made one. But how do you know which one will be better? The glass one sounds cool, and it looks great when you mount it beside your glass sink. Also, the heat insulation ability is good. But for steel-made ones, you can’t even touch them from outside because of the heat, and most of them have no digital display. Also, they are corrosive. That’s why people choose either a glass-made one or an alloy-made taless water heater.

How Do You Want To Use

If you want to use the tankless water heater beside the dining room sink or kitchen sink, then we’ll suggest you have the glass one. But if you want to use it in the bathroom or under the sink, you have steel or alloy made whatever you like. But keep in mind that you need to mount the glass one because it is much heavier than an alloy and steel-made tankless water heater.

Comfortable Size 

As you are choosing to purchase the small tankless water heater, it’ll be convenient if you get a digital display on the water heater. Also try to find a simple one which doesn’t have any complex operation other than setting the water temperature, and turning it on and off.

GPM

Most of the 30 amp tankless water heaters ensure 1.75 gpm to 2.5 gpm. But the more the gpm will be, the more hot water you’ll get in less time. For the shower, we suggest you get upto 4.5 gpm. If you use it for the kitchen sink or dinning sink, then 2.5 gpm is good enough, just half the water flow of your faucet.

Temperature Protection

The tankless 30 amp electric water heaters have a smart modulation system; thus the unit doesn’t heat continuously; if the water temperature reaches the temperature you want, it heats the water according to the volume of supply water. So if you open the faucet for full water flow, the water heater will start working with more heat. If the water flow is lower, the heat will be lower too.

FAQ

  1. Do they make a 30 amp tankless water heater?

– Yeah, many brands nowadays make 30 amp tankless water heaters. The size of this water heater is smaller, and you can have it anywhere inside the house.

  1. How many amps are required for a tankless water heater?

– It completely depends on how many tap lines you want to connect with the water heater. If your house has 5-7 tap lines, you will need upto 120 amp tankless water heaters. But for one or two taps, 30 amps is enough.

  1. How many amps does a RV tankless water heater use?

– 15 amps, 20 amps are quite common for tankless water heaters. But we do not see more than 120 amps regularly. Because of more than 120 amps, the heat protection system will be insecure.

Final Note 

Finding out the best 30 amp water heater is not that difficult, but you need to have some knowledge about the features. Hopefully, you guys have this knowledge now. Always for an electric corded one and the one that can supply at least two lines. Also, don’t forget to ensure a smart modulation system and an overheat protection system. These two are the most wanted features nowadays, so ensure these two before going to more fancy features.
