Customer Reviews

Resin Heater

Approx 18 months ago I purchased a Bosch 1210 to heat our water media that is used to heat
a resin based coating that is applied on a fabric material. It has been in operation on a 12 hr per
day @ 5 day per week average work week, and it has been flawless. The 180 degree temperature is perfect for our operation. This is not the designed purpose but is holding up well with out issues.
If I build another coat machine, it will have another Bosch 1210. The quality of the build, the price
we paid makes this a great value for the 5 star rating. You will not go wrong purchasing this
tankless water heater. I know this is not a standard tankless hot water heater review, but this
is a excellent hot water heater. My digital temperature displays speaks how well the hot water heater works. Resin temp vs water temp vs time. Very efficient. I hope this review will help someone.

discounted prices

I am a huge fan of online shopping because I get discounted prices. When it comes to buying water heater, I am a strong believer in the best quality. That is why my choice number one is Bosch. This fall I bought the new Bosch C 1210 ES NG Residential Tankless Water Heater. Besides having great design and perfectly compact shape, this appliance has proved to be of high efficiency. Also, I found out that the product has extensive energy-saving features. Gosh, I will save money for a new purse - oh, just kidding. But I still think, if you are looking for the cream of the crop or the top quality, the Bosch C 1210 ESC LP 225,000 BTU Tankless water heater should be your number one choice priority.
