Indirect Hot Water heater - Any recommendations?
I need a new hot water heater, mine is leaking. It is an indirect heater that runs off my gas boiler. The entire system is 9 years old. The boiler is a Burnham, the hot water heater is Hotstow. There are generally 2 to 3 adults living here.
I am looking for information from someone with knowledge as to what to buy. Thanks.

9 years is fairly soon for the indirect water heater to go bad. Those type units are usually some of the longest lived options for water heaters. Weil-McLain estimates they should have about a 30-year life span.
Before you spend a lot of money to replace the current system you may want to have our water tested to determine if minerals or acidity may be corroding your plumbing, which would lead to premature failure of anything you install.
You can see a life-cycle cost comparison of different water heating choices at the link provided.
The indirect water heater with a high efficiency boiler can be one of the most cost effective solutions you can get. Why don't you want to stay with that and repair or replace the leaky unit?
Since you have a gas boiler then the next best option with regards to life-cycle cost is a high efficiency on-demand pilotless gas unit.
Gas prices are going up so it might be more cost effective to install an electric on-demand unit, but you would probably have to run a higher current circuit for it.
The standard gas and electric tank water heaters are relatively inexpensive to install, but they are very inefficient and would be more costly over time.
