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.

Why Buy the QH Dual 80L Electric Water Heater?

💧 Large 80-Litre CapacityApprox. 222 litres of usable blended hot water per cycle at 37°C — ideal for 2 occupants.
⚡ 2,000W Copper ElementFast heat-up and long service life; copper resists scale build-up better than alternative materials.
🛡️ Zirconium-Enamel Inner VesselSuperior corrosion resistance — particularly valuable in hard-water areas across the UK.
🧊 40mm Foam InsulationExcellent standby heat retention (λ = 0.22 W/mK) — low heat losses between draws.
🔔 Anode Condition AlarmAudible and visual alert when the magnesium anode needs replacement — extending vessel life.
🌞 Solar PV CompatiblePair with a solar diverter (e.g. myenergi Eddi) to heat water using surplus solar generation.
🔒 Six-Level Safety SystemIncludes overheat cut-out, PRV (supplied), thermostatic protection, and anode monitoring.
📏 Vertical Wall-Mount950 mm tall × 530 mm wide × 280 mm deep — fits standard plant rooms and airing cupboards.
✅ CE Marked & 2-Year WarrantyManufactured to EU safety standards with a two-year manufacturer warranty.

Suitable For

All-electric & gas-free homes New-build flats & apartments 2-person households Retrofit & renovation projects Holiday lets & serviced apartments Hair salons & barbers Garages & workshops Stables & outbuildings Garden offices & annexes Solar PV diversion installations Economy 7 & off-peak tariff users Off-grid & rural properties

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

  • 80-litre capacity — approx. 222 litres of usable blended hot water per cycle at 37°C
  • 2,000W copper heating element — fast heat-up, durable, scale-resistant
  • Energy Class B — efficient standby performance
  • Zirconium-enamel inner vessel — superior corrosion resistance
  • Magnesium sacrificial anode with audible/visual condition alarm
  • 40 mm polyurethane foam insulation (λ = 0.22 W/mK) — minimal heat loss
  • Digital display with adjustable thermostat and illuminated on/off switch
  • Six-level safety system — PRV (safety valve) supplied as standard
  • Vertical wall-mount only — 950 × 530 × 280 mm
  • 230V / 50Hz — 1.5 m lead with 13A plug (removable for hardwiring)
  • CE marked & 2-year manufacturer warranty

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.
