“Installed one year ago and I'm impressed.”

Written on: 23/05/2015 by glen5000 (1 review written)

I have to agree the v-100 is a good boiler and worth the money! I replaced a wood/electric boiler with a nat. gas v100 and have cut my heating costs by 50 per cent with no problems so far. If your considering having one installed find a good fitter that has had experience with this product and dont cheap out on the installation… Read Full Review

“My Biggest House Related Mistake”

Written on: 02/02/2015 by Gerfus (1 review written)

I replaced my oil boiler with a propane Vitodens 100 with a Combi kit. I have hot water baseboard heating. My old system would heat the house in minutes. It now takes several hours to heat the house up a couple of degrees. (I no longer turn down the thermostat when I leave the house through the day). I have an auto thermostat on one zone, it will not get back up to temperature either so I no longer reduce the temperature with it. I get complaints about "no hot water" from everyone visiting my… Read Full Review

un plug the weather sensor, and turn the heating dial upto 6 on the front of the boiler. This will give you 75 degree flow temp, same as your old boiler.

Simple.

“Veinsman Vitodens 200”

Written on: 03/11/2014 by Famousgrouse (1 review written)

our boiler was installed in September 2009. Initial issues relating to vibration through the pipes and excessive noise led to Viessmann attending who could not resolve the problem. Our fitter later installed a pressure relief valve that has reduced the vibration but not the noise, however the boiler needs constantly pressurising. On a separate occasion the boiler went into fault and when our installer stripped down the boiler, the burner was full of water that subsequently spilled out on to the… Read Full Review

I have never come across a vibration on a system especially a 200, and a pressure relief valve would only help if the system was running at a far too higher pressure than it should be.
The expansion vessel comes with a nitrogen charge when new and will last for 3-5 years, but should be maintained and checked very year. I assume this was not done. And therfore would cause the need to re-pressurise the system as you mentioned.

Combustion chamber full of water?
That is a service issue from not cleaning the trap or having adequate flow on condensate pipework. It is more common on boilers with aluminium heat exchangers TBH. Expansion vessel is a service issue too, the vibration through the boiler sounds due to high water pressure (requiring a pressure reducing valve) that is an installation issue. So given the issues you describe are external factors related to install and service, what do think of the boiler?

Written on: 01/02/2015

Another person too scared to consult their installer. Any gas engineer will read your issues and immediately tell you the installation is poor. Combustion chamber full of water.. how is that a boiler problem? This can only be caused by condensate pipe / trap blocked due to poor servicing. Pressure in the system keeps dropping.. Well that is simply a leak. Pressure relief valve installing? If pressure is too high then that is nothing to do with boiler. Either system water content is too large for the expansion vessel in boiler so external one needs installing or the fill pressure is too high to start with.
Vitodens 200W are the most reliable on the market, your installer isn't.

The homeowner also needs to be responsible for ensuring their boiler is serviced and get someone who does more than test the combusion gases.

I am a totally honest man and would like to think that most people are. But reading some of these reviews I would doubt that they are! I own a company that specialises in the repair and installation of boilers, I know almost everything about the Viessmmann boiler rainge. I have only had one pipe split and that was due to a subcontractor not flushing the chemical out of a system correctly. Viessmann boilers are bullet proof and the 200 rainge are out of this world for reliability. We have… Read Full Review

Sounds like a terrible install, there is chemical flushing agent left in the system ! You're lucky the pump has not ceased up also.
none of these are the boilers fault.

Strange then, as I have been fitting these boilers since 2007, no split hoses ever and I am still fitting these now.
I fit the 100w, 200w and the 200w commercial, all exceptional. I have had one dead PCB on a brand new boiler and that is it.
They update the boiler, but this was because it was due an update. Rubber hoses are still used in it. Combining the PRV and condensate was an excellent idea.

Exactly the same thing has happened to me. They refused to fit the hose under warranty and I have had to pay my installer to sort it out, even though I have a 3 year old boiler with a 5 year warranty! Customer service and aftersales care non-existent. Avoid Viessman at all costs they're great till they break down then they don't want to know.

My boiler was installed just over 2 years ago. Apart from a error in the wiring up by the plumber the boiler has worked without fault. I think this comes down to the quality of the installation. The annual service is quiet expensive but keeps the 5 year warranty in place. My only complaint would be that I would like the display back lit… Read Full Review

My Boiler was installed new in August 2008 and has been a constant source of trouble and I would never ever recommend this boiler to anyone, although sadly I did to my brother in 2009. Consequently he also installed this same model and has had worse problems than me and is now looking to scrap it after less than 5 years and replace with a different make. I had a major water leak which almost flooded the house when the plate heat exchanger body, which is only secured by a couple of screws… Read Full Review

I decided to replace my reliable but inefficient boiler with a new Viessman one - costing £3000. My house is now much colder than it ever was!! Viessman was extremely unhelpful- claimed that the boiler works well even though it is constantly turned up to its maximum.

During this cold winter I have further come to appreciate Scott Bivand's January 2009 installation of our Viessmann Vitodens 100 ultra high efficiency boiler that heats our home. Scott and his dad completed the installation in less than one day converting our 1870 house from oil to gas, arranged the removal of the old boiler and oil tank and left the basement cleaner than when they found it.

I have had several issues with them as well since I installed the boiler in 2008.

They is often something wrong with it and I have been calling them out on average od 3 time per year. Now it is rediculous as I am having to pay them 250£ plus VAT to come out for a product that never realy worked. I think they have had to change every circuit board in it over the last 5 years. The the author above, I shall be replacing it and telling everyone I know, not to but this.

If you don't replace with a Viessmann then your using a lesser product!
If I install 40 + a year with 0% call back what does that mean? Either you have a Friday boiler or your installer was an idiot. Think I can assume the answer. You've named the boiler quickly, why not now name the installer? How do you know which is to blame? 9/10 installers do not power flush correctly.
Good luck with the new system.

If someone told me I MUST have a power flush I'd tell them to sling their hook. (That would be YOU, British Gas). It is only needed for old and/or really dirty systems. A magnetic filter is a better investment.

BUT ... I agree that Viessmann boilers (which are British not German) appear to be fine. (We've recently had one fitted).

Veissmann boilers are highly sophisticated & highly energy efficient, however, they are dreadfully unreliable. I am on my second Veissmann boiler & both have cost me a lot in repairs. At the moment my boiler which was fitted new in 2008 is leaking again & has two faults. I do not mind spending money on an expensive unit if it is reliable but over the years I could have bought lots of cheaper, less efficient boilers for the same outlay & repair costs. I dare not risk another winter without heat so I am looking to replace rather than waste more money on repairs.The only good thing I can say about my boiler is that it has decided to breakdown in the summer when good deals will be available on a non- Veissmann replacement.

I have had my rotten boiler since 2008. My experience of its reliability is exactly the same as those of the people who complain about it. Not a year has passed that I have not had to call out a plumber at least three times (and that does not include the extortionately priced yearly servicing) because it has ceased to work.

Of course, the problem might not be with the boiler; it might be to do with stupid English plumbers. I am now attempting to persuade Viessmann to refer me to someone who will over-haul the boiler such that it becomes reliable. I somehow expect that there will be no response from Viessmann.

Seen this boiler on YouTube in very complex installations, never seen before in my life. If it was rubbish they would not do so. They must be reliable. Also this company has one of the biggest employment in Germany. We had a Vaillant before, even it did service, the last years when it worked it gave us huge deplorable bills and it was sometimes so hot inside the house, you sometimes needed to open the windows. Very uneconomic and not convenient.
