anybody who done this setup whr instant heater with conceal piping for the rain shower head, do u face any drop in water pressure?
isit sufficient pressure for the rain shower head without any external water pump?
have anyone done this together with an additional hand shower?
It very much depend on your incoming water pressure. You can try install the instant heater and conceal pipe first. If pressure not enough, than put in the pump.
If I will to buy a square 10" rain shower, I need to ask the seller whether its compatible with instant heater or how shud I check?
Quite confuse in this
Since you know what is water pressure, just ask what is the recommended or minimum water pressure for the 10" rain shower head to work. 10" require higher pressure than 8" or 6" to work. Simply because of number of nozzle.
Either they will tell you need 40-60psi or flow rate of 9l/m. (example) if they tell you anything will do or don't no, better walk out from that shop.

10", i don't think the instant water heater pump can give good water pressure, unless the incoming pressure is already good. Than again, if it flow too fast the water may not be warm enough.
The pump water heater can't handle the 10" shower head or even 6". Even a small but high flow rate shower head have problem too.
What he require is external pump to instant heater to 10" shower head. But as you said, flow to fast water not warm enough. He got to find a better water heater.

Here is a video of I70P with 10" rain shower
Not bad already that 10" rain shower head. Still can work. Did the instant heater with the pump?
