Good product, beautiful, functional and heat well. Used a bathroom to warm the whole Cir UCH hot water. Was very good.
Attachment completed. Simple installation. First, let the water continue to flow at a certain pressure, and then turn on the power. The hot water supply is normal. Without buttons, the water temperature depends on the water flow. Before installation, you can check the installation instructions told by the seller. It is very helpful to reduce errors!
Very good so far, I recommend it a lot to remove the gas from your life! The product arrived very fast in about 10 days. I'll be reporting how things are going next month. To help what I can
