Hi Mike
assuming steam heating, I normally put the steam to the tube side. Pros;
steam is normally at higher pressure - can use a thinner shell wall; less concerns about vacuum.
Less steam volume in exchanger means potentially sharper controllability.
Possibly less insulation cost

Cons:
If water is corrosive, shell may need to be made of a higher grade material - with HTHW water is normally treated If water can scale, cleaning outside of tubes can be more difficult - with HTHW water is normally treated
Condensate drainage needs careful arrangement.

Sometimes when heating untreated water, I put the water through the tubes as they are easier to clean out.

Cheers

Steve

Check out this site:

For custom part manufacturing you download their CAD software and draw what you need, then submit it for a price quote. Very neat.

They are based in New Jersey.
