We are about to buy a Shower Head. It is a Hansgrohe one called Raindance Air. Have just got to check whether it is suitable for our system.

Other's that we have seen specify Low Pressure or High Pressure.

We have a top notch Combi and the Shower will be controller via a Thermostatic Blending Valve and Stop Cock. Is this considered Low Pressure?

 

What you will need to do is check on the shower head what they class as High/low pressure...ie Litres per minute.

Then spend about Ł4.99 on a water pressure tub

Basically it is a can with a gauge on the side, You turn on your tap and run it through the can, and on the side it will show a gauge and that will point to how many litre per minute passes through it......Therefore finding your water flow rate..

See what it is and there is your answer

 

Does the manufacturers quoted DHW output not suffice?

 

 

Whilst plumbers are about can somebody tell me why my central heating rads keep getting air in them???
Have to bleed them about every month

 

get yourself a dump valve on them





















ptssshhhh ptssssshhhh

 

I can't answer that, but thinking about it logically why would it get air in it?

It's a closed system so only 2 possible answers.

1. You have a leak, which in itself quite worrying.

2. You aren't getting all the air out.

Are you bleeding them in any particular order? Is there an issue with the pipework that is causing an airlock? Do you open all the Valves before bleeding? Do you bleed with the pump off?

Remember this is a DIY'ers opinion!!
