Awful app and boiler
Stay well away from dimplex. I have an EDEL RF Air source heat pump water heater in the flat i just moved into. It constantly comes up with “ OVERPRESS ERR” code flashing, so i followed troubleshooting guide and it wont resolve the issue. I have had no hot water now for 2 days. I followed app instructions and scanned QR code on the heater and it sais it is invalid and please input correct code. What a complete joke of a company, do not use these for any of your hot water or heating needs please go elsewhere. You have been warned by a legit user of their products.

Heaters
Some heaters communicate some don’t and then start communicating and the others stop.
Resetting hub and turning heaters off don’t help.
Fairly frustrating

Absolutely Atrocious
Dimplex Quantum Storage Heaters are rubbish.
£142 of electricity used in 10 days!!!!!

regularly disconnects and need manual reset
not helpful remotely. Also you can’t use this if you’ve locked the heaters. So you can’t actually adjust remotely if they’re locked manually. But also the app doesn’t function when unlocked. I wish I had wasted so much money on this system
Disappointed
Purchased heater and hub for heating detached summerhouse for occasional random use, discussed suitability with retailer. This is not a suitable product for this set of circumstances, cannot turn heater off from app, the only solution the Dimplex technical support team could come up with was to use the “in all day” program and turn heater off using this program allowing me to turn it on when wanted. Unfortunately this means the heater comes on every morning at eight o clock at a temperature of 21 degrees centigrade requiring me to use the app to turn it off or pay for heating all day, instead of the occasional one hour session I need!,
Minor point the person at Dimplex said they would email a user guide to help me explore what I find a non intuitive app, to date not turned up!,

Rubbish!
Constantly need reconnecting and when app updates you lose all data again! Heaters good app and WiFi control rubbish!
Font is so tiny
Why is the font so small in the area screen ? So much space yet you make me get a magnifying glass to read it.
Still very clunky to change heating times.

2-year review - basic and useful
Having used the app in conjunction with the Hub for almost 2 years controlling 2 night storage heaters, its facilities are basic but effective, allowing me to reliably control the radiators using the schedules I’d setup, and manually override when needed. Remote access has proven useful when it’s possible to go out (being able to turn-off heating when I’d forgotten to do so manually before I’d left home), and turn the heating-on whilst out so I return to a warm home. It would be a significant benefit if there was an option to link with local weather forecasts so charging overnight was adjusted to meet anticipated demand the following day, to avoid wasted electricity consumption. All-in-all a useful and reliable app that does what it needs to do, and has the potential to be something even better.

Avoid
Really poor given the price. The consumption figures are hugely unstated. I find the app to be inconsistent in saving settings. Moreover, despite my best efforts, and willingness to spend vast amounts on heating, my heaters never ever attain the programmed heat output. Hugely disappointing.
Great when working
5 Jan. Usually works fine to control 4 Quantum heaters BUT on the coldest day of the year it failed despite resetting router, hub, ipad and phone, deleting and reinstalling app. Broadband and devices were fine. App constantly buffering failing to update profiles. Went downstairs for the 3rd time to manually programme heaters. Would like to know why.

Servers down, no 3rd party integrations
Servers are down or slow very often lately and as a result heaters can’t be controlled from this.
Unnecessarily complicated, google home or HomeKit or an API would work much better.

Server down?
Lost connection. Re-installed. Can’t log in to my account. Given the cost of these heaters and the ridiculous cost of the hub, the least I expect is for consistent server uptime. Spend some of your profits on building a robust, redundant server infrastructure please.
Edit 5/01/2026
Server down again, on one of the coldest night of this year. Thanks Dimplex - really outstanding work!

Dimplex Controls our heating
Excellent app for controlling Dimplex heaters in our village hall. Saves all the bother of walking to the hall to turn on the heating. Now we can do it remotely from either an iPhone or iPad. Also, thank you for the technical help with the app.
What have you changed?
I am using 2 iOS devices to access our heating system, an iPhone and an iPad. They login to the same hub, with the same user names (email) and passwords that are shared via iCloud so they ARE identical. For years I have been able to login from either device, sometimes both at the same time, now I can’t, it’s just the one device only. In my case it’s an iPad. If I try to do anything by clicking on the app, register for example all I get is ‘Bad Request.’
I have tried resetting the password, nothing, it doesn’t help at all. Still only the one device allowed.
What have you changed? Because up until I was forced to change the password NOTHING has changed my end, and as I said before the login details are stored in iCloud so are identical.

Extremely over complicated
Had the app for a few years and still failing to use successfully, Profiles create ok but fail to set on each heater.
Very difficult to change a heater setting on an ad hoc basis.

19 Nov app failed today on the day that the weather has really changed. I’m going to have a very very cold house tomorrow. I have tried EVERYTHING to fix it. Now not accepting password even when I’ve just reset it.
Problem
It’s stopped working!
Awful App & Products
Truly awful app (constantly buggy, falling over and not working) and products (issues connecting, constantly disconnecting from the hub and a hub which constantly fails). Don’t contemplate buying the products. Go with a competitor.
Server down?
