I had a demonstration of the concept 20 hot system. Could not find fault with it for the time they were here. (Hence my question.)
Julie Phillips is very nice they don’t just try and sell you a system, I got the impression they would like to offer lots of support concerning your own business.
Never had a demo from Ionics but it would have to be exceptional to be better than concept 20.

I have bought from both suppliers, and found that Julies knowledge was very good on all subjects asked. The system i have is cold, but can always be upgraded to LPG hot when / if required.
The hand over from Concept was a full day- very thorough. The hand over from ionics was about 1/2 hr not so thorough!!
Running costs are obviously less on the Concept, as we all know about resin costs from Ironics.
Cant comment on the hot because i didnt even ask for a demo - out of my league price wise.
The demos from Concept lasted about 4hrs, at their premises, Ionics came to me and did a demo on a bungalow, very usefull!!!!!!! say no more. I bought the Ionics, as at the time there were not as many suppliers as now.
The service from Concept is i find more helpful, and its not all about making a sale, Julie and Carl are very knowledgeable and can offer some helpful advice in progressing your business. All the parts used are top quality, and even the reels included are Klaber, not cheap plastic ones.
no reach and wash brand, no local back-up etc etc.
Looks like their trying to be like ionics but on the cheap. I cant see any reason why someone would buy theirs instead of ionics (quote from Tennet)
I have found just because of the reach and wash brand does not bring in extra premium work, local back up??? depends where you live doesnt it? and as for trying to be like ionics but on the cheap, check the prices. Concept are not cheap, personally i think Ionics are not aswell made, and i think i can comment after owning both, my ionics is 3-4 yrs old now, my concept is 6mths old, chuffed with it.
Ionics really need to step up their after sales service, and start looking at using quality parts on the system, the attitude i had on the phone when enquiring about a second system was very poor, no offer of proper demos, no offer of a decent deal as it would have been a 2nd system, no follow up calls from them. The impression i got was that they didnt really want to do a deal. Whereas you will not find anybody more enthusiastic than Concept about their system, with confidence in the build, and a positive attitude about window cleaning like you would not believe, i left their premises very positive!
