The Story

Quality Heating’s 50 litre QH V2 electric water heater is a wall-mounted, fully automatic storage cylinder built for properties without a convenient gas supply. It pairs an illuminated digital control panel with an enamel-coated tank (both the inner cylinder and the heating element carry a protective enamel lining), a magnesium anode for long-term corrosion protection, and a thick polyurethane insulation jacket to keep standby losses low. An onboard Smart usage-learning mode studies your household’s hot water habits and pre-heats ahead of typical demand, while a dedicated 80°C antibacterial cycle gives the tank a periodic high-temperature clean. Suited to a flat, ensuite, kitchenette, hair salon chair or annexe where mains gas isn’t an option.

Qualified installation required
This is a fixed-wired, mains-pressure appliance fitted with a non-return valve and an 0.8 MPa pressure-relief safety valve, so UK installations over 15 litres fall under unvented hot water (G3-equivalent) competency rules as well as BS 7671 wiring regulations. The dedicated circuit must be at least 1.5× the heater’s maximum current, RCD-protected, and the socket outlet fixed at least 1.8 m above floor level, positioned so it cannot be reached by anyone using a bath, shower or pool. Have the unit installed and the supply tested by a qualified electrician.
Key Features
Precise digital control
An illuminated panel lets you set the cylinder temperature in 1°C steps between 30°C and 75°C, alternating between actual and set temperature on the display so you always know where you stand.
Smart usage-learning mode
Hold the Smart button for 3 seconds and the heater starts learning your household’s hot water pattern, automatically firing up roughly an hour ahead of your typical demand so hot water is ready when you need it, not constantly on standby.
80°C antibacterial cycle
A dedicated high-temperature sterilisation mode heats the tank to 80°C and holds it for 30 minutes before reverting to normal operation — a periodic clean cycle against bacterial growth in the stored water.
Triple safety protection
Built-in overheat protection, automatic pressure relief if tank pressure runs high, and anti-backflow protection work alongside continuous self-checks for dry-firing and sensor faults, shown on the display as error codes E2–E5.
Enamel-coated tank
Both the inner tank and heating element are enamel-coated, and a magnesium anode rod is fitted to sacrificially protect the cylinder from corrosion — extending service life in hard-water areas.
Insulated for efficiency
A 40 mm-thick polyurethane foam jacket (λ = 0.22) minimises standby heat loss, and the built-in mixing valve supports multi-point water supply to more than one outlet.

Frequently Asked Questions
How much hot water do I actually get from the 50L tank?
The 50-litre tank heats to a maximum of 75°C in normal use (80°C during the antibacterial cycle), and that hot store is blended down at the tap with cold mains water via the built-in mixing valve, so the usable warm-water volume at shower temperature is greater than the tank size alone. As a guide, this size suits 1–2 people for everyday bathroom and kitchen use.
Can I install this myself?
No — it must be installed by a qualified, competent professional. The heater needs a dedicated, RCD-protected electrical circuit, a properly rated and tested earth connection, a wall capable of supporting at least four times the unit’s full water weight, and correctly fitted safety/non-return valves. Floor-mounted installation is not permitted — it’s a wall-hung unit only.
Is the heating power adjustable?
No. This model has a single fixed 1500W element — there’s no switch to step the wattage up or down. The temperature itself is fully adjustable between 30°C and 75°C via the digital panel.
What does Smart mode actually do?
Once activated, the heater monitors when hot water is typically drawn off and begins quietly pre-heating around an hour before that time, so you’re not waiting for a cold tank to recover. The indicator glows orange while it’s still learning your pattern and turns blue once it has enough data. A power cut or disabling Smart mode clears the learned schedule.
What happens in a power cut?
The heater has a memory function and returns to its previous power and temperature settings once supply is restored. If you ever need to reset it to factory defaults, hold the power and temperature buttons together for 3 seconds — it will default to 75°C instant-heating mode.
What do the E2–E5 error codes mean?
E2 indicates the tank has been energised without being filled with water (dry-firing); E3 and E5 flag a fault on temperature sensor 1 or sensor 2 respectively; E4 means the water temperature has exceeded 90°C. In any fault state the heating relay disconnects automatically — contact a qualified engineer rather than resetting and continuing to use the appliance.
