i need to replace my 40g indirect water tank. anyone have any recommendations? i'm thinking something around the same capacity, or a little more wouldn't hurt.

my current one had all 4 connectors on top, but i guess that wouldn't be an issue a plumber to redo the connections. i'm in NYC if that matters.

i have a 93,000k btu boiler.

    Any indirect rated over 93k will maximize your boiler. Aside from some of the Amtrol models most 40 gallon models will e rated higher.

    Don't oversize it. How many people are drawing hot water from it? Are there hi capacity fixtures in the house? Keep in mind that a standard 40-gallon gas-fired water heater typically uses a 40,000 BTU burner and fires at about 70% efficiency. Your 93,000 BTU boiler will put much more energy into the water and probably runs at least 80% efficiency or higher. I'm willing to bet you need not purchase a larger tank.

    HTP SSP50 will do the job. The heat exchanger and tank is made of S/S
