Vaillant ecoTEC Pro 24 Condensing Combi Gas Boiler

This is simply the worst boiler I have had.

Totally disappointed from the word go. I think they are relying on their old reputation but sadly the product is unreliable & expensive to repair along with all the expensive parts.

After only 3 years i need an expansive vessel , pressure sensor. It's been depressurised 4 times in 3 years.

Leaking pressure very common & error code F75 all requiring call outs.

Total cost of repairs so far are £2540

Pathetic

Having lived with a fault on my boiler for some time, with acidic water from a failed condenser trap outlet connection, leaking into a bathroom wall and affecting plasterwork and painting, I'm not a happy bunny. The fault itself is not a big deal and should be easily fixable. However I've been treated apallingly, stood up twice for repair visits, with Vaillant coming up with any excuse possible for making me take time off to be home then not showing or doing the work. They quite clearly do not want to do guarantee repairs especially in inner London, and will find any excuse possible not to.

Basically if the Vaillant guarantee is the decider in your boiler hunt go elsewhere.

I purchased my property with a brand new Vaillant ecoTEC Pro 24 Condensing Combi Gas Boiler installed. All went well for the first couple of years. Since then I have spent a fortune repairing it with constant F75 problems. In the end, my gas engineer, who actually rang Vaillant has strongly suggested I purchase a Worcester. Ladies and gentlemen, don't buy Vaillant if you value your hard earned cash!

We have had a Vaillaint eco TEC Pro for seven years. It has been a source of constant frustration, perpetually having F75 pressure problems and requiring urgent and expensive repair. I have reached the point where I am no longer prepared to pour good money after bad and will be replacing it. I will never purchase anything Vaillaint again and suggest you do likewise. The model was unfit for purpose when released on the unsuspecting public and the constant updates / revisions / new replacement parts indicate that Vaillant know it. Buy another brand!

Bolier from ecotec range a couple years old. Jan 2013 f75 error. Engineer found faulty pressure sensor and seized pump. Replaced both. Jan 2013 f75 error. Contacted Vaillant - they are totally disinterested and insist their boilers are quality. Home come this error is not in their standard manual? How come they themselves distributed a repair kit for this exact problem? Here is the kit description, just Google it: Vaillant Service Kit F75 0020023721. The absolute disgrace of it that they provide a part to resolve a design problem and refuse to help customers that have been hit by the issue. Have you tried their call out rates? Ridiculously high. For a boiler that costs £1200, they want £300+ a visit. So basically you get it repaired three times for the cost of a new boiler = OUTRAGEOUS.

Alternative: Bite the bullet and have it replaced with a decent boiler.

Called them out in my area of east Anglia (NORFOLK) for a service an expensive outlay for the time taken to service it, but i initially felt confident that it was money well spent. Only to find within a day or so after the service a fault had occurred!, called vaillant who explained that i would have to find a further large sum for a call-out.Which would go to the cost of any work etc done.The engineer arrived i explained the problem it took minutes to access and fix he departed telling me i also needed a plumber for a part which i could obtain easily as their call-out repair plan did not cover this!.Purchased plumbing part on the advice given only to be told nothing wrong with the original!!when plumber arrived.

I have a strong suspicion that the fault was caused when the service!? took place.

I was very happy with my Potterton boiler that I had had for about 20 years and rarely if ever went wrong. I was advised by Swale Heating that I would save money and this Vaillant boiler would be more energy efficient - well it is that because it keeps breaking down and hence I have no heating or hot water. A total and utter nightmare. I have Had this boiler for 3 months and have had to call out Swale Heating 4 times since then. Each time the fault says F22 and its to do with the water pressure getting too low. this is a major continuous fault Steer well clear of this boiler I can't tell you how much trouble it is. I wish to God I hadn't replaced my very reliable Potterton boiler. Total rubbish and the engineer who came out for the fourth time had the cheek to say that I'll probably have the same water pressure problem for the next six months!!!! No that is not normal. I am going to write to watchdog I am so mad. Feeling very frustrated at the moment.

Bought a Vailant eco tecc pro about 5 years ago. Within the first few weeks the water sensor pressure valve had to be changed. This same fault occured approx 4 times over 18 months.

I was then informed that Vailant had bought out a part modification which basically fitted the same valve higher up in the system and out of trouble so to speak. This has now been fitted not as a matter of course but because I got to hear of the modification and asked to have it fitted.

Last winter in the snow my boiler broke down on F72 over and over again. Engineers replaced every part known to man and if I had not had an extremely hard working and able trouble shouter/engineer on hand would have needed me to buy a new boiler. I was without heating for approx 3 while engineers struggled with the appliance.

I have no option but to purchace expensive boiler insurance on a yearly basis now. Might this be a ploy by Vailant?

Just as well I did as a grinding humming noise has begun to emit from the inside of the boiler tonight well in time for this years snow forcast for next week! Suspect is the diverter valve.

Take my advice stay well clear of this boiler unless you want to be on Valium and pay for anger management.

Heating seems to be ok, but only tested it once so far. Water as title says is a waste of time. This is due to when opening the hot tap to wash your hands on a sink that is only 10ft away from the boiler the water fails to heat up before you turn the tap off. So in other words we will always be washing our hands in cold water after going to the toilet. I don't know what is 'eco-friendly' about it as you use gas, water and electricity for hot water that you never get to use. A senior heating engineer has assured me that the boiler is working fine and that this is just the characteristics of the boiler. This problem is exacerbated whilst trying to run a bath as the water almost stops whilst another sink is in use.

In my opinion this boiler is just a glorified Ascot, and not a very good one at that.

So in conclusion if you need plenty of water on tap (no pun intended)I would look elsewhere.

we had an ecotec pro 24 installed on 16/3/11,it is now 22/4/11 and it does not give hot water to the taps,although the central heating seems okay,vaillant dont really want to know saying that the installing engineer is responsible,draw your own conclusions.
