Hoping for the best second time around

Bought this tank to replace a 9 year old Lochinvar that started leaking. Was installed two months and this tank began leaking. Hoping the second new replacement tank does not leak until it's at least 9 years old. Supply House did a pretty good job with communicating with Lochinvar and getting a replacement under the warranty.

Hopefully the third time will last.

This is the third unit I installed. The first one was leaking internally after 13 months. The second on was leaking from the thermistor port after 3 months. Supply house representatives were very responsive and helpful reference the replacements and returns. Maybe bad luck with product but great customer service from Supply House!

All stainless steel and heats fast

Love the fact that this is all stainless steel. Heats must faster than a plate style exchanger. I gave it only 4 stars because I wish it came with 3/4" openings instead of the 1" that I had to adapt.

I would buy this product again

This Lochinvar Squire indirect water heater replaced a 21 year old water heater that was no longer manufactured; the water inlets and outlets on the Squire were close to my old tank so it was a fairly simple connection, I have not had any problems with the Squire it seems well built and well insulated, I had lots of family over for the holidays and never had any problems of running out of hot water.

Q: What is the EF/Thermal Efficiency of the 40 Gallon, Squire SIT040 Indirect Water Heater by Lochinvar? I need this for equipment rebate.

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.

Q: how does the hot water heater turn on the furnace. My furnace runs about 10 minutes every hour during the summer when no heat is required. This is even at midnight when no hot water has been used in several hours.

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

Q: I am planning on using this for hot water to a sink in a bathroom, a clothes washer, a sink in a kitchen, and a dishwasher. What size pipe to my boiler should I use? Does it matter if I use PEX-A or PEX-B oxygen free tubing?

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.

Q: Does this qualify for an energy tax credit? I bought one in December of 2010. Thanks.

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.
