Fantastic
By Terry B.

Purchased 02/19/2018 | 
Review Posted 03/14/2018 
We have used a Bosch tankless water heater for 22 years when it finally had to be replaced. We chose this brand and model because of its features, capacity, and ease of installation. We are very pleased with our purchase as it doubled the hot water flow rate of our previous model. The installation was easy and painless. The heater exceeds our expectations.

Review Posted 02/12/2018 
I purchased this unit to replace a similar model I have had for years. It has been a good, reliable unit. I also installed one in another house I had, and have a smaller Bosch gas unit as a point of use unit in this house. They have all been very reliable.

Wonderful Product!

Review Posted 11/30/2017 
We had a Bosch on demand hot water heater that we bought 8 years ago. It went out so we bought this one to replace it. It has all the same features. One recommendation is to clean out the hot water pipes at least once a year. Our old one was gunked up and I think that is what made it quit working

Impressed With The Unit - Bosch 1050 ES.
By Michael H. 
Bozeman, Montana
Purchased 10/04/2017 | 
Review Posted 10/26/2017 
This unit is solid, as expected from Bosch. My gas line initially was undersized from a previous gas tank powervent unit. Install was reasonable, but took some effort and some plumbing expertise, about 8 hours all told, removing the old unit. Instructions seemed fine. Had initial error messages, but found a mounting screw missing the right fan unit, once replaced and all fasteners checked for tightening, has worked flawlessly since. I have been running the unit with about 70K BTU for 10 days, works fine for showers etc..., line being increased to 209K BTU in the next day or so, then will enjoy its full capacity. I would do this unit again. Rated quality at good due to missing and loose fasteners. Very easy startup, once installed.

eComfort had the best price of 6 stores I had looked at. The Bosch C 1050 ES is a wonderful product. It is quiet, efficient and is saving us both electricity and water. Our water bill is starting to shrink.

review 8 image 1
Installed the unit myself. Good written instructions and YouTube video. Used 3" diameter PVC pressure-rated pipe for combustion air inlet and flue gas outlet. Easy start-up: Turn on water, turn on gas, and push button. Has been running good for 2 months. Very quiet.
