My home was built in 1950 and has base board hot water oil heat and a coil to heat my hot water. The original heater lasted for 45 years with no major problems (yearly maint. by local heating co.) It was replaced about 7 years ago at their recomendation. When I updated my master bath with antiscald shower valve I had only warm water. The company tech said I needed a new coil ($600) the new ones only last 5 years. Same water same pipes? The heater is a New Yorker from Colmar, PA. Junk? Should I replace the coil or retro a elect. hot water heater? Help!

The old shower valve worked fine, but the anti-scald isn't hot enough? That's not a problem with the coil. Somebody is clueless or trying to sell you a bill of goods.
You might need a hotter setting at the oil burner/coil. Certainly if you had dialed it down to a lower (safer) setting, some of the A-S valves won't be hot enough.
More likely, you need to adjust the anti-scald valve. They come with instructions about taking the cover off and rotating a little plastic doo-hickey a notch at a time until you get the desired temperature.
Unless the anti-scald valve or some of the plumbing done at that time cross-connected hot and cold lines. Then all the fixtures in that area of the house will get cold and warm water coming in instead of cold and hot.
