Customer Reviews

old water heater couldn't provide my family with enough hot water

My household is quite large and the old water heater couldn't provide my family with enough of hot water. So, I went online and bought the new Bosch Therm 520 PN NG. I have 2 large bathrooms and the Bosch Therm 520 PN NG non-condensing tankless water heater handles the job really well. Besides being able to heat up to 5.2 gallons per minute, the appliance shows 80% of efficiency, which is remarkable on its own. This tankless water heater is intended for indoor installation only. You can set it to work in either condensing or non-condensing regime. It is great quality product, I recommend you buy it!
