Will this shower replace my current Dimplex/Redring/Creda/Galaxy shower?

It will depend on the type of shower you currently have. If you have a mains cold fed shower then this shower should be suitable. You will need to contact an installer to confirm whether your current plumbing, wiring and fuse protection are suitable.

Can I upgrade to a higher kilowatt (KW) rated shower?

You will need to contact your electrician. In most cases we would not recommend upgrading to a higher KW rated shower as the existing wiring and fuse protection are unlikely to be suitable.

Will this shower be physically bigger than my current shower?

Our showers have a slightly larger footprint than most of our older models. This is so that tiling shouldn’t need to be altered. The depth profile is likely to be slimmer though.

Will this shower have more water pressure than my current one?

The Verve and Vital showers are mains cold fed. This means that these showers are subject to the incoming mains pressure and length of the run from you stop tap to the shower.

Will the electrical/water connections be the same as my old shower?

Verve Answer. The Dimplex Verve is a SmartFit shower. This means it has 6 electrical and 8 plumbing locations. Entry can be done from the left, right top and bottom. It achieves this by having multiple entry points, knock outs and connection points to accommodate the existing pipe work and electrical connections.
Vital Answer. The Dimplex Vital has entry points for both water and electric on the right hand side as you look at the shower. The entry can be top or bottom because it has knock outs to accommodate.

Can my installer use the existing holes from the previous shower to fit the new Dimplex Verve/Vital?

If the holes line up and are structurally sound then this is fine. If they do not line up then new holes will need to be drilled into the tiling. It is NOT acceptable to add any additional holes to the showers back plate to accommodate an existing fixing hole; the shower has pre-drilled fixing holes to secure it to the wall. This will void the ingress protection rating (IP) that the shower has and could cause the shower to fail and potentially be dangerous. It could also affect the warranty of the shower. I would recommend speaking to our Customer Experience Team for more information if required.

Fault Self-Help

My Vital shower keeps dripping from the shower head. What should I do?

The likely thing to cause this is too much pressure holding the flow shut off valve open. You need to check the pressure coming into you property. Pressure does fluctuate; typically overnight there is higher pressure due to less people using water. So it could be that the increased pressure/change in pressure has been enough to force the valve open slightly.

Therefore it is likely that the increased pressure/change in pressure has been enough to force the valve open slightly.

My showers water temperature goes from hot to cold during use. What is the cause of this?

This is usually due to a fluctuating flow rate through the shower. The most common cause of this is ‘Water Theft’ such as someone running a tap, washing machine or dishwasher elsewhere in the property. Our showers require a consistent flow rate of 8L/pm for 8.5KW and 9L/pm for 9.5KW showers. Due the flow being reduced by other appliance/s ‘theft’ it will cause the thermal cut out to engage. The thermal cut out is a self-resetting item at its first stage; this will be why it goes from hot to cold continually.
The other common cause of this is something restricting the water getting out of the shower resulting in the water staying in contact with the element for too long, causing the thermal cut out to engage and reset. The restriction will be scale in the head or a kink/collapsed hose.

I have to keep the on/off button held in to operate my shower. What is the reason for this?

In our experience the most common reason for this is the back plate of the shower being overtightened against the wall. This will mean the manual valve is too far away from the back of the button and consequently isn’t held in to keep the water flowing. Typically this is because the area behind the shower is not always tiled and the back plate is overtightened. This only needs to be as little as the width of the tile to cause this issue.

The water coming from my shower is completely cold. What is the cause of this?

The most common cause of this is ‘Water Theft’ such as someone running a tap, washing machine or dishwasher elsewhere in the property. Our showers require a consistent flow rate of 8L/pm for 8.5KW and 9L/pm for 9.5KW showers. Due the flow being reduced by the other appliance/s ‘theft’ it will cause the thermal cut out to engage. The thermal cut out is a self-resetting item at its first stage so try leaving it for 5-10 minutes to reset.

If the shower continues to run cold it is likely the thermal safety device has activated at its second stage. The second stage will not reset and the thermal cut-out will need to be replaced. This is a safety device designed to prevent the user getting scolded. It is important to get the cause of the overheating is resolved otherwise it will happen again. The most common cause would be a restriction of flow. This is commonly caused by having one or multiple other appliances drawing water at the same time e.g. washing machine, dishwasher or the toilet being flushed.

The water coming from my shower is too hot/overheating. What is the cause of this?

Try adjusting the settings. The temperature control knob and power control knob do need to be adjusted from time to time. This is because the ambient temperature of the incoming water supply varies throughout the year. It is hotter during the summer and colder during the winter so it is perfectly normal to have to adjust the control knobs to achieve the desired temperature. This can also be a result of a slow flow rate of water through the shower. Our showers require a flow rate of 8L/pm for 8.5KW showers and 9L/pm for 9.5KW showers. The slower the water passes through the shower the more time it spends in contact with the element and consequently the hotter the water will be. Make sure any service valves/inline isolators/stop taps are open fully. Another cause of this is ‘Water Theft’ such as someone running a tap, washing machine or dishwasher elsewhere in the property. Due the flow being reduced by other appliance/s ‘theft’ it will cause the thermal cut out to engage. The thermal cut out is a self-resetting item at its first stage; this will be why it goes from hot to cold continually.

Where do I find the serial number?

The serial number can be found on the underside of the shower close to where the hose comes out. The location can be a bit tricky to see so using a small mirror may be useful.

How do I find out what kilowatt rating my shower is?

This can be obtained by checking the model number. The model number is located on the underside of the shower close to where the hose comes out. The location can be a bit tricky to see so using a small mirror may be useful.

What do the different settings on my shower mean?

There are four settings as well as the temperature control knob. Finding the correct combination for your desired temperature is the key. It is normal to have to adjust the settings on you shower. Our showers use a staggered element, so getting the balance between the element and the temperature control knob (which controls the flow rate) are important. The four settings are as follows:
• Cold = Cold water only. No heating element engaged
• Eco 1 = Lower kilowatt element is engaged. Useful tip – when using this setting you will need to have the temperature dial set quite high. This setting is ideal for use in the summer when the ambient water temperature is higher and the shower can use less energy to achieve good temperature.
• Eco 2 = Higher kilowatt element engaged. Useful tip – This setting is ideal for use during the seasonal changes, winter to spring and autumn to winter. The shower will use the higher element but isn’t running at full capacity so is still being as economic as possible.
• High = Highest setting. This is the shower working at full capacity; this setting uses the most electricity to heat the water as both of the elements working at the same time.
