Plumbing Fixtures - Other FAQs
What is the difference between an electric shower and a mixer shower?
An electric shower heats cold water on demand inside the unit, so it doesn’t rely on a hot-water tank; a mixer shower blends pre-heated water from a boiler or cylinder with cold water to reach the desired temperature. Electric showers are great for homes without a hot-water system, while mixer showers often provide stronger flow if you have a powerful central hot supply.
How much electricity does an electric shower use?
Usage depends on the unit’s power rating and flow. A middle-range unit similar to a 7.5 model uses about 25,600 BTU per hour, or roughly 10 horsepower equivalent, when at full output. Running time, temperature setting, and the household electricity tariff determine actual cost, so shorter showers and lower power settings reduce bills.
Can I install an electric shower myself?
Because electric showers require a dedicated electrical supply and water-tight installation, national codes typically require a qualified electrician for the wiring and a registered plumber for the plumbing work. Doing it yourself could risk safety and invalidate warranties, so professional installation is strongly recommended.
How do I choose the right shower for low water pressure?
For low-pressure supplies, look for electric showers or mixer units specifically rated for low-pressure operation. Check minimum flow and pressure specifications in gallons per minute and PSI terms, and consider installing a pump if you want stronger pressure — but ensure the shower and system are compatible before adding a pump.
What routine maintenance keeps showers working well?
Regular maintenance includes descaling showerheads monthly or quarterly in hard-water areas, checking seals and hoses for leaks, cleaning strainers to prevent blockages, and testing thermostatic valves to ensure stable temperatures. Promptly address dripping or unusual noises to prevent more serious faults.
