Dales-Electronic :

EU standard states a minimum pressure of 1 bar or 15 psi ~ You should not need a booster pump as water companies are required to supply this minimum pressure ~ Ian

Dales-Electronic :

So all boiler run at an input pressure of 1 bar and above

Customer :

We live in an 'old' gated community where the pressure is less than 1 bar. Is there a possibility for a booster pump?

Dales-Electronic :

Can you let me have your model number or are you just looking for a boiler that will work on low water pressure?

Customer :

one that works with low water pressure

Dales-Electronic :

OK have you any idea what pressure you have at the supply ?

Dales-Electronic :

OK I have the information that you require to allow you to use a Combi boiler with your low pressure supply. Kindly ping me when you are available and I will give you the details ~ Ian

Dales-Electronic :

Do you still require the information that you requested earlier?
