Ultraflow unvented cylinders are manufactured in the UK from duplex stainless steel, with premium components fitted as standard throughout the range. Large stock holding, trade pricing, and 24–48 hour delivery — backed by a 25-year cylinder warranty.
Every Ultraflow cylinder is manufactured in the UK from duplex stainless steel, with high quality components fitted throughout. From Incoloy immersion heaters to Honeywell valve sets and Lowara & Grundfos pumps, no compromises are made on the components that matter.
Ultraflow cylinders go beyond the basics. Calorifiers and horizontal models are designed with installer flexibility in mind — dual immersion heaters and high insulation as standard across the range, so the cylinder works harder for longer.
Both Enfield and Rushden branches carry extensive stock across the full cylinder range, ready when you need them.
Competitive trade accounts with preferential pricing. Quality UK-manufactured cylinders at prices that work for every job.
Fast dispatch from both branches so cylinders arrive on site when you need them, keeping your installation on schedule.
The industry’s longest cylinder warranty — 25 years on the cylinder body and 2 years on parts, as standard.
