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!… Read Full Review

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… Read Full Review

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… Read Full Review

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… Read Full Review

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… Read Full Review

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… Read Full Review

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… Read Full Review

As a british Gas engineer i can safely say these vaillants are the best on the market. i never visit these boilers at work but visit plenty of worcester boilers every day. I have a vaillant in my kitchen, at my brothers and my mums house with NO problems at all. Dont put the boiler in on a dirty system as this will kill any boiler very quickly… Read Full Review

Bought the ecoTEC pro 24 for a rented property in the belief that Vaillant would deliver reliability as well as efficiency. Boiler now 18 months old and just broken down for the third time. Vaillant utterly indifferent unless they can send out an engineer at eye watering cost. I located a local Vaillant specialist who was vastly more reasonable but indicated that this model appears to be defective but Vaillant will not help.
Only glimmer of hope may well be its scrap value!
Bought a Worcester… Read Full Review

I have been installing various makes of boilers for the past 21 years and finally found the best brand in Vaillant. Last year(2010) we installed over 60 of the appliances and only had trouble with 1, which incidently only involved a phone call(not premium rate like other companies) to Vaillant where a technician talked through how to solve the problem. The only thing I must say is that if you add the boiler to an existing system please make sure it is clean… Read Full Review

Bought the Vaillant Ecotec Pro 28 a year ago (Sep 2009), and just after the 12 months guarantee expired the boiler did not provide any hot water or heating. The service engineer advised that the sensor had gone and was a common problem with these type of boilers. After a few weeks lost the heating but had hot water, this time a diverter valve had to be replaced by an engineer. The diverter valve was cheap and nasty made from plastic.
I am not happy with this boiler and not sure what else i… Read Full Review

We had a Vaillant Eco Tec 24 installed. Initially we were very pleased but it broke down just after the 12 month guarantee expired (no hot water or heating)and we had to have a new circuit board. It is now in it's 3rd year and we have again had to call for an engineer for the same problem. I can see why they only give a 12 month guarantee. I would not recommend this boiler… Read Full Review

I had an Eco TEC Pro 24 boiler fitted in November 2007, by May 2008 this boiler had leaked 3 different times and completely ruined my kitchen. As it was still under warranty Valliant confirmed that this was a manufacturing fault with the boiler, and agreed to replace the boiler with a new one free of charge. this was fitted in November 2008, and has this month, (July 2010) again started to leak. The plumber has confirmed that it is the exact same problem, where the washers are not working… Read Full Review

I put a lot of effort into checking out which would be the best boiler for our 2 bed flat.I eventually chose the Vaillant Ecotec 28 Pro Condensing Combi boiler. I am very glad that I did. This is a very solid, well-built bit of kit. We had a standard system before with the separate hot water cylinder etc and the hot water delivery was ok. But this new Vaillant delivers hot water at a pressure that is astounding and heats up very fast. We also had the boiler completely re-positioned and it is… Read Full Review

Just had a Vaillant EcoTEC Pro 28 combination boiler fitted...very quiet and seems very sturdy. Maybe too early to know whether it is very reliable but Valiant have a great name. Disappointed that they only offer a 1 year warranty instead of a more standard 2 year warranty but hopefully will not need to use it!… Read Full Review

As a registerd gas engineer with forty one years in the industry I do very little installation these days.
I worked on most boilers with my long service at B Gas before working for myself and Vaillant generally were very good quality.
I have fitted three eco tec pro boilers recently for friends and a neighbour and all seem to be really good, very fast hot water delivery and equally good heating.
To early to comment on how reliable but Vaillant boilers I service or repair have generally got to… Read Full Review
