Tankless Electric Water Heater on just 30amp 240V?

Can I replace a 50 gallon electric water heater with a tankless electric one? The current 20 year old water heater is hooked to a 240V 30A line and needs to be replaced soon. I only need hot water for two people in a townhouse.

wouldnt work without a major electric upgrade. you will need at least a 100 amps, since the water must be heated as used.
your way better off with a standard well insulated tank

Thanks.
Any particular brands to look at? Any that I should stay away from? I'm not one to go the cheap way but I also don't want to buy more than I need.

really matters little, only 3 US manufacturers. Buy from big box store for slightly better prices. Newer tanks are foam insualted for energy savings. Buying a more expensive tank gets you things like brass drain valve, WAY better than plastic ones.
Look at first hour ratings and get the biggest tank that will physically fit the space, to avoid running out of hot water and with a nice long warranty for better stronger tank.
the cheapest anything is rarely a good deal long run, built to meet a absolute price point, and the most expensive is for luxury buyers. mid priced everything appears the best deal.

the Sears (Kenmore) water heater that I bought several years ago has been great. I would avoid the heaters with only a 6 year warranty-the insulation is not very good.

Isn't getting the best first hour rating at odds with getting the biggest tank? Bigger tank means more water to heat before it gets hot no? And I would think for a given size tank, the first hour rating is going to be just about the same regardless of brand, given he has a 30 amp circuit to work with. That determines how much energy he has to heat the water.

Nope, the electric ones use a lot more juice than that. Get one powered by propane or natural gas instead.
