: i'm a litle confused.
+++ Yes!
wouldn't you need to remove the coil if you were going to clean it?
+++ NO!
The water tubing is clogged INSIDE, so the pipes are disconnected from the water line and an acid is run through the INSIDE of the coil without REMOVAL.
it seems i would risk having to get a new boiler even if i tried to clean it. is this right?
+++ No. You would risk getting burned with acid if you don't do it right. That's why it is an experienced PRO job - YOU wouldn't do it, he would.
: Would you recommend adding a mixing valve and running the temp higher or is the 80 gal enough usable hot water. i'm not sure about the cost difference as to whether it is cheaper to buy extra tank capacity or add a valve to a lower capacity tank.
+++ Install a good Holby mixing valve as part of the installation investment cost. Water should be stord hot enough to kill bacteria over 150F; which is too high to have coming out of a tap. You get more capacity; but also stay healthy.
: Since there are so many different types and brands, would you be able to recommend a brand which say uses a smooth coil inside?
+++ A Weil Gold indirect heater has a stainless-steel jacket, not a coil, so it has more surface that resists liming. They also have large heat recovery ratings.
But, they might not be carried locally. Get a unit that most people in the area use because they have supplier support and the plumbers like them because they have little trouble and know them well.
roughly what kind of cost should i expect?
+++ Expect a cost so high that you would cry. Then you don't feel so bad when you see the estimate from three different installers that you found from friends that were happy with their work.
