Q: Can a Galaxy shower be connected to a cold mains supply?
A: All instantaneous showers should be connect to the rising mains water supply, unless the unit is a power shower or mixer unit, as there are limitations on water services in order for the unit to perform correctly. Units can be connected to a header tank providing there is adequate head height to generate a minimum of 1 bar pressure.
Q: Can a Galaxy power shower be fitted to a combi-boiler?
A: There is no problem, but PLEASE NOTE! The following:- DO NOT connect to a combination cylinder unless there is guaranteed 114 litre COLD supply to the cylinder as the shower can deliver up to 14 litres per minute. It is advisable to check that the infill rate from the float operated valve meets the output requirements. It is recommended that there is a minimum of approximately 114 litres (25 gallons) of HOT water storage per appliance.
Q: Does the wiring to my existing electric shower need to be upgraded if I was to fit a higher kilowatt rated unit?
A: All wiring must be carried out by a fully qualified electrician and must comply with the current wiring regulations to meet the specification of the unit to be installed.
Q: What can I do if there is not enough mains water pressure to operate an electric shower?
A: If there is in-sufficient water pressure for your unit it form the COLD water rising mains this would normally be down to a poor service from your service provider “lines could be blocked or restricted”, if this is not the case then your unit could be fed from a header tank with an adequate working head height. If you want all the benefits of an Instantaneous Electric shower then consider purchasing a Galaxy Aqua 9000XP, which is a Pumped Instantaneous Electric shower, which can be installed to the COLD water storage tank.
Q: What is the minimum flow rate and water pressure required for a Galaxy electric shower?
A: The minimum running water pressure for the shower unit is 1 Bar.
Q: What things do I need to think about when replacing an existing electric shower?
A: If replacing an existing unit you must ensure that your water and electrical services are adequate for the kilo wattage of the unit to be installed.
Q: What size fuse does a Galaxy electric shower require?
A: The installation must comply with the current wiring regulations to meet the specification of the unit to be installed. This all depends on the kW rating of the shower unit. Please see below: 7.2kW shower = 32 Amp fuse 7.5kW shower = 40 Amp fuse 8.5kW shower = 40 Amp fuse 9.5kW shower = 40/45 Amp fuse 10.5kW shower = 45 Amp fuse Please note in order to comply with the current building regulations you should have a competent certified installer carry out any electrical work to the IEE Wiring Regulations.
Q: What Galaxy shower will suit a gravity system?
A: A power shower or mixer unit are the only recommended units as there are limitations on water services in order for any shower unit to perform correctly, standard mains shower units can only be connected to a header tank providing there is a adequate head height to generate a minimum of 1 bar pressure. Otherwise consider a Galaxy Pumped Instantaneous Electric shower
Q: What Galaxy shower will suit mains fed water system?
A: Any unit except a power shower or mixer unit as these need to be gravity fed.
Q: Do I need a pump?
A: You can only pump water from a storage tank to feed to a shower; you cannot pump mains water directly to a shower as it goes against local water by-laws.
Q: What effect does the kW rating have on my electric shower?
A: Electric showers only take water from your mains cold water supply and heat this water by passing it over electrically heated elements. The temperature of the water you get from your shower and the flow rate is therefore determined by three key factors: 1. The temperature of your mains cold water supply (this can vary from 5°C in winter to 20°C in summer) 2. The heating ability of your element in kW 3. The pressure of your mains water supply in simple terms, the higher you’re chosen showers kW rating the better the potential water flow rate from your shower at your preferred showering temperature. As a guide you can see below how the kW rating affects your shower flow*: * 8.5kW up to 27% more flow than a 7.5kW heater * 9.5kW up to 42% more flow than a 7.5kW heater
Q: What type of plumbing fitting is required to connect to the inlet of a Galaxy electric shower?
A: An easy fit or compression fitting is required to connect to the unit, providing they meet the specification of the installation.
Q: When installing a Galaxy electric shower, what size electric cable is required?
A: The installation must comply with the current wiring regulations to meet the specification of the unit to be installed. Recommended cable size: 7.2kW shower = 6 mm2 cable size 7.5kW shower = 10 mm2 cable size 8.5kW shower = 10 mm2 cable size 9.5kW shower = 10 mm2 cable size 10.5kW shower = 16mm2 cable size. However please note in order to comply with the current building regulations you should have a competent certified installer carry out any electrical work to the IEE Wiring Regulations.
Q: What happens when an incorrect fuse size is fitted for an electric shower?
A: If the fuse is under rated then the fuse will keep blowing. If the fuse is over sized then if there is an electrical problem then the unit could burn out and this could be a potential fire hazard.
Q: What water and cable entries do Galaxy showers have?
A: Most units unless otherwise stated have the water entry on the bottom right hand side of the unit that can be connected to a water supply coming from bottom, rear or top of the unit, the electrical connection block is located on the right hand side, mid way and has a knockout section for cable entry.

These details will then be passed to one of our recognized engineers within your area who can provide a service to repair the unit, in line with our terms and conditions.
Q: Water is leaking from the bottom of my unit, what could be the problem?
A: If water is leaking from the base of the unit it could be due to the shower being over pressurized (a buildup of lime scale or a bent/restricted shower hose) “water will be coming from a small black pipe behind the shower hose”
Q: Where can I find the serial number on my Galaxy shower?
A: All serial numbers are located on the bottom left of the unit next to the water out-let hose
Q: The flow of water from my Galaxy shower seems very poor, what could be the problem?
A: If you experience poor flow from your unit this could be due to poor water services or that the unit is being used on half heat setting and trying to achieve a hot shower “increasing the heat setting should increase the water flow rate”.
