Glowworm Flexicom / Ultracom Boiler Pump – Refurbished | Part No. 0020014171

Heating circulation faults, cold radiators, and boiler lockout in a Glowworm Flexicom or Ultracom system often trace directly back to a worn pump head. As the pump loses efficiency, it can no longer maintain the flow rate required to circulate heated water through the primary circuit — leading to poor heat distribution, intermittent hot water, and recurring overheating faults. The Glowworm Flexicom / Ultracom Boiler Pump (Part No. 0020014171) is the correct refurbished replacement, restoring reliable water circulation across the full Flexicom CX / SX and Ultracom CX / CXi / SXi / Ultrapower range.

This is a professionally refurbished genuine Glowworm component — stripped, cleaned, and run-tested before dispatch. The superseded part number is 0020014180; the Grundfos part equivalent is 59866564. Each unit is confirmed operational before shipping and supplied with a full 12-month warranty. Minor cosmetic marks may be present consistent with removal from a functioning boiler.
