The Shower nozzles and toilet inners show a little sign of white Scale and a Reddish Iron Scale but time and test will tell. The owner said she was old school 70 during the day and 55 at night. By the looks of the old fashion T87 Mercury T stats with a sharpie mark D for day and N for Nite approx on those numbers ... I believe her. The Hot water was from a 40yr old Electric HWH.. OUCH!!!! It will not be there on Day 2 of ownership.
It sounds like you use your fair share of hot water, but the question is...do you ever try to take multiple showers at once? (or shower with the dishwasher running, etc). If you just do one thing at a time, a tankless should do the job just fine. If you frequently have more than one "draw" on hot water at the time time, I encourage you to either use a tankless coil with 3/4" tappings, or make the jump to an indirect hot water heater. Another option is to use the tankless with some sort of storage. Take a look at these pictures: Pictures Of Your Boiler
The man that posted them uses an electric hot water heater with an aquastat and circulator...the water in the tank is circulated through the tankless coil in the boiler as needed. This kind of setup has a few advantages over a stand-alone tankless: 1. You have 3/4" tappings on the tank. 2. You don't need to keep the boiler as hot. 3. You can use the electric elements to make hot water when the boiler is down for service.
Regardless of how you intend to produce hot water, you definitely need to get the water tested and plan on treating it as necessary. Tankless coils DO NOT LIKE hard water, and the performance will quickly fade as the coil builds up with deposits. Indirects are less sensative to this, but it is still a problem.
While you are looking at the water system, check the air pressure in the pressure tank, check the pressure switch, etc etc. These things are often neglected.
Lastly, I know of someone running an S260 in Cobleskil. If you would like to see their boiler in action I should be able to dig up their phone number.
