Can you run two showers one fuse?
You will require two separate circuits. An 8.5Kw shower will have a 37 amp current draw and no diversity is allowed on calculations regarding a shower.

Electric showers require their own electrical circuit, which in general will have the highest electrical demand out of your household appliances. All circuits in a bathroom must be protected by a RCD (Residual Current Device).
Do electric showers use a lot of electricity?
You may be surprised to see that an electric shower has topped our list of most energy-consuming appliances, but it takes a lot of energy to heat the water and could use 1,460 kWh in a year.
Can you get a 7kw shower?
If “pressure” (flow) is OK on cold setting (even if head is as low as you say), then unlikely to be a restriction in supply (as same single water feed). 7 kw really is very borderline for a decent shower, particularly in the winter months when the water supply temperature is so much colder).
What do I need to fit a power shower?
They require a hot and cold feed from water tanks. All power showers will need to be installed by a Part P qualified electrician as they require an electrical feed into a bathroom.
What size cable do I need to install an electric shower?
regulations. The size of cable required is determined by the kW rating of the shower, the distance between the shower and the consumer unit and the way the cable is to be fitted. The minimum size will be 6mm2 but in some cases 10mm2 or larger will be required.
What is the difference between a power shower and an electric shower?
A standard pump-assisted power shower uses hot and cold water from a domestic hot water tank which is heated by your household boiler and stored in the hot water cylinder. An electric shower only uses a cold-water supply and just heats the water as it is used, somewhat like a kettle.

Which electric shower is the most powerful?
A 10.8kw electric shower is the most powerful electric shower there is and it means that it will provide improved pressure and a higher water temperature.
How long should a shower unit last?
A high-quality glass shower enclosure should probably last about 20 to 30 years if properly maintained, but there are many nuanced details that can affect this general lifespan.
Is a 8.5 kW shower powerful enough?
7.5kW and 8.5kW electric showers
If your household hosts a smaller water tank or an unreliable water supply, this range of kW rates will probably suit you best. 7.5kW and 8.5kW shower rates require less power so the gentler flow of water will mean your shower is unlikely to ever run cold.
