Does this heater need special connection to the electricity supply, or can it run on a normal plug?
Also, when you say small wash basin, how small is small?
This unit does not come with a plug, it needs to be spurred in and is only for hand wash.
we have previously bought vented units because installation is very simple and no specialist accessories are needed, can you tell me if this unit needs an external pipe for any water to drip from, also does this unit come with all the parts necessa
The unit doesn't need an overflow pipe just a mains feed and a pipe to the tap. Unfortunately the tap is not included however everything else is installed.

As the unit is above 3KW it needs thicker cable than standard ring main.

This unit can not be fitted upside down for safety reasons as it has a flow switch that would not work if fitted up side down.
I have 8 bar water pressure where I live
can I fit this with a pressure reducing valve to bring it inline with the max of 6.5.
The heaters will tolerate a water pressure of up to 10bar, so 8 will be OK. you can install a pressure reducer but not within 1 meter of the heater to allow for any backpressure relief from the heater.

The temperature of the water is hot enough to wash up dishes however the maximum temperature can not be adjusted. Please click on the PDF attached to the product for the temperature rates as this depends on the flow rates.

Installed a perfect 3500 water heater earlier this year but it's stopped working. Power is reaching the unit and the light comes on when you run the tap but no hot water. Have checked the flow. Is there a reset for the element ?
If you could please check the following:
- is the voltage too low (supplying installatio overloaded)
- the temperature of the entering water may be too low.
- water flow too high.
If these do not assist in this matter please contact our Customer Services team on 08000 913171
Can this unit be fed to the mains hot water feed
No this is because the heaters run on full power, raising the water temp according to flow rate based on an entry temp of circa 10-15*. If the entry temp is higher than 20* the water will be super heated and trip the thermal break inside.
Re quick code 133362 3.5 kw instant water heater:
1) Does it need a special venting tap? (ie not an ordinary one)

Hi, I asked this question on Friday / Saturday, but have not had a response. I would appreciate a reply. In answer to someone else's question you said this needs to be run off a spur with a 15.2 amp fuse. I can't find a a fused spur, with a suitable fuse
We do not stock 15.2amp fused spurs and we would advise you to contact a qualified electrician to install the water heater correctly.
can you use this for a shower for dogs i.e control temperture
Although we have customers who purchase the Perfect 55 water heater (our code 133365) for hair salons, we cannot recommend this to wash your dog, since this product is not designed for that purpose. The temperature of the hot water is controlled by the flow rate of the incoming cold water and can be variable.
Will the cable from a 3kw immersion heater be sufficient to operate the heater.?
We would not recommend to use the cable from a 3kw immersion heater. The 3.5kw water heater will need the correct current with a fuse of 15.2amps. As with any electrical appliance of this nature, we would recommend to have the water heater installed by a qualified electrician/plumber.

Does a low mains water pressure of 1.5 bar affect the working of the unit? Are spray nozzles in the tap used necessary for some reason?
This water heater can run on a minimum of 0.7 bar of water pressure, so 1.5 bar would be okay. The spray tap fitting provided ensures peak performance from the water heater.
Hi is it possible to install this in a room away from the sink ie in a cuboard approx 1.5m away from where the sink will be located?
Yes, but there may be a run off of cold water out of the length of piping. If the heater is not used for longer periods, the water in the 1.5m piping will cool, so when the hot water tap is turned on it will have to drain the cold water in the pipe.
Just purchased a "35" unit. Being installed under in cupboard under sink in small cloakroom. Can the 20 amp water heater box be fitted close to heater, i.e. In cupboard or does it have to be fitted outside? Many thanks
As long as the 20 amp fuse box is sealed and accessible, it can be installed anywhere on the circuit. However, a qualified electrician will have better advise on your particular circumstances.
