Great question, Joseph!
If you want to stick with something similar to what you already have you would want to go with part # DMC74FR. Make sure to measure the space your original water heater is in just to make sure this water heater will fit. This heater is 12-3/4" tall x 12-3/4" wide x 19-7/8" deep.
You will also want to pick up the door which is part # DMC58FR which needs a cut out of 12-3/4" wide x 12-3/4" tall. There is a possibility that your cut out may be larger, if that's the case you would want to get the conversion kit instead. That's part # DMC24FR, this includes the door you will just need one or the other.
Tankless water heaters are becoming way more popular and we do carry a wide range of options. If you're interested in something like, drop a comment. Just let me know how large your space is and the cut out size and I can find the perfect one for ya!
Hopefully your OG heater is still holding on so you don't have to take any cold showers.
