Indirect water heaters energy efficiency ratings are dependent on those of the boilers they are connected to; if your boiler is a high efficiency model you may see up to 20% better efficiency ratings than a direct fired water heater as per Lochinvar. This unit comes with two inches of R-13.4 High Density Polyurethane foam yields the lowest standby losses in the industry.
Hi Joe There is a well in the side of the tank where you can insert an aquastat that in turn gets connected to your boiler. You will likely need to add a zone and pump to your boiler to do this. Incidentally an even better way to make hot water is a solar system that uses what are known as evacuated tubes to heat your water. I recently added such a system at my house because of the same problem with the boiler running all summer to heat water. Got to love those tankless heaters. My system has 60 evacuated tubes installed on the roof and a 119 gallon stainless water heater. (Should last forever) The water heater has two coils, one in the bottom of the tank and one at the top. Hot antifreeze from the roof collector circulates though the bottom coil when the temperature of the collector on the roof is 10 degrees warmer than the tank. The upper coil is used for make up when the sun is not shining. Make up heat comes from the boiler in the same way it would if there was no solar collector. Google "solar hot water heaters" there is a ton of information out there to be had. By the way my boiler shuts down after the heating season is over and almost never runs all summer. The only exception is if there is no sun for several days in a row. There are also tax rebates from the federal government and many states have incentive programs to help pay for the system. Hope this helps
There should be a thermostat in the side of the tank that's wired to the furnace. If the temperature inside the tank drops too much it will kick on the furnace. If you have a knight boiler you should be able to adjust the water temperature
You would want to use oxygen-barrier PEX to connect this unit to the boiler. You can use either PEX-A (which is more flexible) or PEX-B. You'll generally want to use 1" tubing to connect with the boiler.

Indirect water heaters themselves do not qualify because their energy efficiency ratings are dependent on those of the boilers they are connected to. If you purchased your boiler last year, it may qualify.
