80 Litre QH Dual Electric Storage Water Heater
The Quality Heating QH Dual 80 Litre Electric Water Heater is a large-capacity, wall-mounted hot water storage cylinder built for gas-free properties that need a reliable, high-volume supply. Part of the premium Extra Life series, it features a zirconium-enamel inner vessel, a copper heating element, and 40 mm foam insulation — delivering efficient, long-lasting performance rated at Energy Class B.
With an 80-litre capacity and a powerful 2,000W element, this unit is well suited to two-person households and single-occupant properties with higher-than-average hot water demand. It mounts vertically on a load-bearing wall and connects via a standard 13A plug or can be hardwired for a permanent installation.

Product Description
The QH Dual 80L stores 80 litres of water. When heated to 65°C and blended to a comfortable 37°C shower temperature, the cylinder delivers approximately 222 litres of usable hot water per cycle — comfortably covering morning routines, washing up, and bathroom use for two occupants without running out mid-draw.
The unit mounts vertically on a load-bearing wall using the supplied bracket. The 1.5-metre mains lead connects to a 13A fused connection unit, or the plug can be removed for hardwired connection — giving installers flexibility on the electrical termination. The supplied pressure relief valve (PRV) must be fitted and plumbed to a safe discharge point during installation.
The zirconium-enamel inner vessel coating offers superior resistance to the pH and mineral variations found in UK mains water — especially important in hard-water regions such as the South East, Midlands, and East Anglia. Combined with the magnesium sacrificial anode (with its own condition alarm), this gives the cylinder excellent long-term corrosion protection. The six-level safety system, digital display, and adjustable thermostat give both homeowners and engineers confidence in day-to-day operation.
Key Features

Installation & Trade Notes
This unit is designed for a vented (low-pressure) cold water supply. 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 connect to a sealed (pressurised) system without appropriate pressure-limiting provisions. This model is vertical installation only — it cannot be mounted horizontally.
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 — a Pentec UBIC inlet combination valve is recommended and available separately. Flush the cylinder before commissioning and set the thermostat to a minimum of 60°C in accordance with HTM 04-01 (Legionella prevention).
Frequently Asked Questions
How much usable hot water does the 80-litre cylinder provide?
When heated to 65°C and blended to 37°C, the cylinder yields approximately 222 litres of usable hot water per cycle — enough for two occupants with normal daily use.
Can this unit be mounted horizontally?
No. This model is designed for vertical wall-mounting only. If you need a horizontal wall-mount option, please see the QH Dual 80L Horizontal model.
Is the pressure relief valve included?
Yes — a PRV is supplied as standard and must be fitted and plumbed to a safe discharge point. This is a legal requirement under the Water Regulations.
Can it be hardwired?
Yes. Remove the 13A plug and connect the supply cable directly to a fused connection unit or consumer unit. All electrical work must be carried out by a competent person under Building Regulations Part P.
What does the anode alarm do?
The magnesium anode protects the inner vessel from corrosion. When it's depleted, the unit triggers a visual and audible alarm — prompting timely replacement and significantly extending cylinder life.
Is it compatible with Economy 7 or solar PV?
Yes to both. Use a time-switch for off-peak Economy 7 overnight heating, or pair with a solar diverter such as the myenergi Eddi to use surplus solar energy for free hot water.
