120 Litre QH Dual Horizontal Floor-Standing Electric Water Heater
Floor-Standing 120 Litres 3–4 Person Capacity
The Quality Heating QH Dual 120 Litre Floor-Standing Electric Water Heater is the largest freestanding cylinder in the QH range — designed for households with higher hot water demands where wall-mounting is not an option. Part of the Extra Life series, it combines a 2,000W copper heating element, zirconium-enamel inner vessel, and 40 mm foam insulation in a compact cylindrical package rated Energy Class B.
At 120 litres, this floor-standing unit delivers a substantial hot water reserve for 3–4 occupants, or for properties with high peak demand such as holiday lets, larger bathrooms with baths, or commercial washroom facilities. It stands upright on its own base (Ø 450 mm × 1,030 mm tall) — no wall fixings required — making it the right choice wherever wall construction, accessible housing standards, or plant room layout rules out a wall-hung cylinder.

Product Description
The QH Dual 120L floor-standing cylinder stores 120 litres. When heated to 65°C and blended to a comfortable 37°C temperature, the unit delivers approximately 208 litres of usable hot water per cycle — enough for a family of three to four to take showers, run a bath, and cover kitchen use throughout the day from a single heating cycle.
The cylindrical body (Ø 450 mm × 1,030 mm tall) occupies the same compact floor footprint as the 100L version — just 135 mm taller. Standing independently on its base, it is a practical choice for utility rooms, boiler rooms, or any space where wall fixings are not feasible. For larger accessible housing projects or commercial installations requiring several units, the consistent footprint makes planning and installation straightforward.
The copper heating element brings rapid reheat after a high-demand draw, while the zirconium-enamel inner vessel coating provides strong resistance to the pH and mineral variations encountered across UK water zones. The magnesium sacrificial anode — one of the few cylinders at this price point to feature an audible and visual condition alarm — gives the vessel significant long-term protection. The supplied PRV and six-level safety system ensure the installation meets all statutory requirements from day one.

Installation & Trade Notes
This unit is floor-standing — place it upright on a flat, level, structurally sound floor surface. No wall bracket is required. The supplied PRV must be fitted and plumbed to a safe, visible, frost-free discharge point in compliance with Water Regulations and Building Regulations Part G. Do not lay the cylinder on its side.
All electrical work must be carried out by a Part P-registered electrician. Connect via a 13A fused spur or remove the plug for hardwired connection; the circuit must be protected by an RCD. Water connections are ¾" BSP — an inlet combination valve (e.g. Pentec UBIC) is recommended and available separately. Flush the cylinder before commissioning and set the thermostat to a minimum of 60°C in line with HTM 04-01 Legionella guidance.
Frequently Asked Questions
Does the 120L cylinder need wall fixings?
No — it is freestanding and stands securely on its own base on any level floor. No wall bracket is required or supplied.
How much hot water does it produce per cycle?
Approx. 208 litres of usable blended hot water per cycle at 37°C — enough for 3–4 occupants covering showers, baths, and kitchen use throughout the day.
How does it compare to the 100L floor-standing model?
The 120L model is identical in diameter (Ø 450 mm) but 135 mm taller at 1,030 mm. It provides approximately 34 additional litres of usable blended hot water per cycle — enough to support one extra occupant or significantly higher peak demand.
Is the pressure relief valve included?
Yes — a PRV is supplied as standard and must be plumbed to a safe discharge point as a legal requirement under the Water Regulations.
Can it be hardwired?
Yes — remove the 13A plug and connect to a fused connection unit or consumer unit. All electrical work must be carried out by a competent person under Building Regulations Part P.
Is it compatible with solar PV or Economy 7?
Yes to both. A 120-litre cylinder holds significant thermal mass — ideal for overnight Economy 7 heating that keeps water warm well into the following day. Pair with a solar diverter to use surplus generation for free hot water during daylight hours.
