Water Hammer Arrestor on hot water line
(OP)
Is it of any use to install water hammer arrestor on hot water line .My project consists of housing rooms with 50 liters electric water heaters .the owner requested WHA on both cold ends and hot ends . You know that Water Heater adds about 0.5 bar pressure loss to the circuit , so methinks it will work as a pressure attenuator .Does anybody think it fit on hot line other than Automatic Washing Machine .

Only if you get water hammer.
The heater might act as a form of attenuator.
for a multi room / building, you normally get enough attenuation with multiple users.
If they are simple and cheap, put them in.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

The water heater tank has almost no damping effect on downstream piping.

It is how fast or slow the valve opens.

The system is a pressurized one ; water is pumped directly to buildings . Also it is a housing project of not less than 300 toilets .
The said project will be done in say 13 cities so when it is possible to save 25$ , this sum will be about 100,000$.
My point was that water going to water heater undergoes pressure drop in two angle valves and a check valve and two hoses .Also it was a common complain that hot water was not OK for low buildings with overhead tanks .

The problem with trying to use heaters by themselves as surge devices is that they let water out equally as fast as they let it in, just a little bit later.

Install the water hammer arrester at the end of the branch line within 6 feet of the last fixture served. The fixture is where the water hammer originates.
