Rinnai water heater. what bar pressure is needed?

[riverbear]

sorry it's a Paloma not Rinni

 

we have a old Paloma water heater (changing in a year or so £££) and need to know what bar pressure the full water system should be with a total water system fit out.

 

Dose the fresh water pump control the Bar pressure to the Paloma, will it still hold pressure with cold tap and hot tap running?

 

We are also moving the bathroom from next to the heater to 25ft away with the heater staying put (in kitchen). Can this affect the pressure?

 

Not to worried about hot hot water just a warm shower till we change heater.

The pressure is less important than the flow rate.

 

I'm puzzled about the situation you are asking about. Any run-of-the-mill water pump will make the Rinnai work. Which make and model of pump do you have now? Does it work now, or not?

 

Yes the extra distance can affect the pressure. It probably won't though.

 

The warmth of your shower is dictated by the heat rating of your Rinnai, combined with the actual temperature of your stored cold water, the temperature you consider makes a 'warm' shower, and the flow rate through your shower.

 

The slower the flow rate, the hotter the shower will be!

Usually a 10 litre/minute 28psi pump is about right for one of these heaters, something like a Shurflow Trail King 10.
