FAQs

Q1: What does ‘A Rated’ mean on a circulating pump?

“A Rated” refers to efficiency performance that meets European energy-saving standards, meaning the pump uses less electricity while maintaining strong water circulation – delivering lower running costs compared to non-rated or older models.

Q2: How does this pump automatically adjust performance?

Thanks to its permanent magnet motor and differential pressure controller, the A Rated pump senses system demand and automatically modulates speed and flow. This reduces unnecessary energy use and matches flow to the actual heating requirement.

Q3: Can this pump run continuously?

Yes – circulating pumps are designed to run continuously in heating systems to ensure hot water flows throughout the loop. Modern designs like this one adjust output and often run at lower speeds when full power isn’t needed, saving energy.

Q4: How do I remove air from a circulating pump?

Air can reduce efficiency or cause noise. If present, bleed the system or follow manufacturer instructions to release trapped air — ensuring optimal performance and quiet operation.

Q5: Will this pump fit my heating system?

This model is compatible with most domestic central heating and hot water circulation setups using 1½″ BSP pipe connections and up to 6m head – ideal for radiators and underfloor systems. Always confirm pipe size before ordering.
