FAQs

What fill pressure do I need?

Set the duty pump cut-in to the static height of the building plus about 0.35 bar. This unit fills up to 5.5 bar.

Is an expansion vessel included?

No — membrane expansion vessels are supplied separately and sized to BS 7074. Send us the static height, system volume, flow and return temperatures, glycol content and final working pressure and we’ll size it.

Can it be used to fill the system?

No — fill the system first and vent all air. The unit then tops up small losses and maintains pressure.

Does it meet the Water Regulations?

Yes — the break tank gives a type AB air gap, and a double check valve is supplied for the mains supply.
