'Fast delivery just to the wrong address.'
I put in a different address for shipping but it was delivered to the billing address.
Thank you for your feedback. As this order was all done online and paid through paypal - you would have put in all of your own details in the shipping address and billing address. Paypal however, often default your shipping address to your billing address before we even get to see the orders.
I am very sorry about this confusion and unfortunate delivery mistake.

'Underfloor Htg UK GOOD; DEVI Reg Touch instructions useless'
Underfloor did extremely well, delivery next day, and they were very helpful when I needed to query the instructions for setting up the DEVIreg Touch underfloor heating timer.
I would not agree with all the statement that this timer is easy to set up.
Many thanks for your comments.I am very sorry to hear that you did not find the Devi Touch easy to operate. Devi do offer a portal programmer which when completed allows you to add a simple 5/6 digit code which pre-programs your Devi touch unit for you making the process a lot easier.
I certainly hope that this helps.
If we can be of further assistance please do not hesitate to contact us.
DEVIreg Touch Programmable Thermostat (Pure White)
The instructions included with the timer stop halfway through the process, and you need to download/print at least 30 pages off the internet to figure out how to operate it.
The instructions from Devi also give you touch.devi.com to refer to, and this page does not exist on the internet, and also refers to a web code interface set up via a 'web generated code', and if you try to open it on the net you get a warning 'DANGER do not open' on your screen.
So it would be helpful if Underfloor heating could either include their own instructions for the uninitiated like me, or insist that DEVI produce instructions that are actually correct.

'Reducing installation information is not a good idea!'
Your service was quick and efficient. My concern was with the DEVI product information and installation information. I have previously fitted a DEVI mat however the installation information was minimal and no explanation given for the pack content. Fortunately I remembered most of the installation steps. The one that I didn't was answered by DEVI customer help. My point is that the product is good but the installation information is poor as is the online information. If DEVI ask you can feed back this information to them.

'Very poor delivery service. Very unreliable and inconvenient'
It was supposed to be delivered to my home address. Two days later I find out they didn't deliver because they didn't have a contact name!!!!!!!!!!!!!!!!
And for me to collect from a pharmacy
That's ridiculous!
Thank you for your valuable review.
As this was ordered online your delivery details would have been passed through to our courier automatically as entered.
They would attempt delivery and by default if no one is available to receive the courier would deliver to the nearest click and collect point rather than returning the undelivered goods to us as this is often less convenient for the customer.
We are sorry for the inconvenience this has caused you.

They sold us three zones but only two thermostats. Therefore cannot control heat in one zone. The Devi Matt floor was fitted by an electrician and an experienced carpenter laid the floor. However as I write this the heat only works in 25% of the room. Will likely have to lift the newly laid floor and will be writing to their customer services
