Vaillant boilers or Worcester boilers? Which is better?

Vaillant VS Worcester

Vaillant or Worcester

 

 

Vaillant and Worcester Bosch are both domestic heating and hot water product manufacturers. Both are highly regarded brands with consistently high customer satisfaction scores. Both make all types of boiler, conventional boiler, combi boilers & system boilers. When trying to decide between a Vaillant and a Worcester boiler, there are a few things to consider, e.g. price, size, control, and energy efficiency. First, we should get an overview of the two companies and the range on offer. Ps if you’re interesting the in the: Pros & Cons of Combi boilers VS Conventional boilers .

So Vaillant or Worcester? Let the battle commence. Read on…

 

Vaillant Boilers 

Valliant is a German company which has been a key player in the heating market for over 135 years and now sells its products in more than 80 countries. Vaillant was founded in 1874 and is currently Europe’s second largest company in this sector, focusing on energy-saving and environmentally-friendly products with polished German engineering.

 

Their range provides options for all sizes of homes and different budget options from the Ecotec Pro & Ecofit pure to the more premium Vaillant Ecotec Plus, which now comes with a 10-year guarantee for Vaillant advance members. Their boilers range in price from £740 to £1,500 depending on their size and sophistication. Most boilers come with a standard 2 to 5-year warranty, which can be extended up to between 5 and 10 years at an additional cost. (Excluding Vaillant Plus range).

 

In general, Valliant customers are happy with their range of boilers. Many claims that Vaillant boilers are particularly easy to use and are made to a good standard. Whilst some people have had issues with their boiler, they report that problems have been dealt with quickly by the company’s team of 200 specialist engineers.

Worcester Bosch Boilers 

Worcester was founded in 1962 in the United Kingdom and later acquired by Robert Bosch GmbH in 1992 to form part of the Worcester Bosch Group. Similarly to Vaillant, Worcester Bosch makes energy-saving goods its main focus, while also creating schemes that promote activities dedicated to conserving the environment for future generations.

Their range of domestic combi boilers includes the Greenstar Junior and Greenstar Si series. Their Greenstar Ri series is a popular conventional boiler for more traditional homes that use a cold water tank and hot water cylinder. They also produce system boilers such as the Greenstar 12i, 24i, and 30CDi. Their boilers range in price from £570 to £6,188 and are supplied by certified Worcester Bosch installers. Their boilers come with a standard 5-year warranty, with an option to extend to 10 years for free if the boiler is fitted and maintained by a certified Worcester Bosch installer.

 

Worcester Bosch has a strong reputation with very few negative reviews. They score very highly for their reliability, although some customers have reported that the controls on their boilers can sometimes be difficult to use.

Awards

Both brands have won several awards over the past decade and Worcester Bosch has won the Which? Best Buy Awards in the gas boiler category for seven years running. Their boilers have also had a 6-year run at an overall rating of 92% for customer satisfaction and engineer recommendations.

The Vaillant Ecotec Pro range, in turn, was also awarded the Which? Best Buy Award in 2016 but can also claim to be the only boiler brand to have also been awarded Quiet Mark status by the Noise Abatement Society.

What are Installers saying

On pistonheads.com installers have commented on the build quality of the two brands, with ‘moles’ commenting:

On lemonfool.co.uk opinions were divided, with many commenting that there is little to choose between the two. However, it is worth noting that several installers commented that they have to repair Vaillant boilers much less frequently than Worcester Bosch:

And Frank Finn, of Frank Finn plumbing, echoes this in his own blog comparing the two brands:

“Considering all the factors and individual needs, my verdict would favour the Vaillant boilers.

One of the things we find helpful from Vaillant is there allowable flue length, a valiant 832 could go as far away from an outside wall as 8m whereas a Worcester 29cdi would be 6.4m giving you greater flexibility on the positioning of the boiler.

We have found the Vaillant to be quite easy to fix when things do go wrong cutting down on long call out times. Whereas we have found with Worcester, they have a few parts which are not easily accessible, without removing other parts on the boiler.”

Also, if you head over to some of the gas engineer groups on Facebook, a lot of engineers joke about the impossibility of repairing Worcester boilers, some of the problems that come up, that should not come up, like the replacement of parts that should be easily replaceable on a routine visit, require the whole boiler stripping on.

VERDICT?

Both brands make excellent A-rated boilers and come with very few complaints and high customer satisfaction rates. In my opinion, I would recommend the Vaillant boiler range over Worcester Bosch for two reasons; firstly, Vaillant boiler parts are more readily available, last longer and have few complaints about wait times for repair and secondly the Quiet Mark award. There is very little difference in price, but Vaillant are often slightly less expensive when including installation costs, but this saving might be used to offset against taking an extended warranty, that being said the Vaillant Ecofit Pure range offering a 7-year guarantee & the Ecotec plus range now offeri10-year year guarantee is pretty strong!

From the comments of multiple installers, I would expect most Vaillant boilers fitted now to last long after their warranty expires, if services and maintained properly, whereas Worcester Bosch may not last quite as long.

 

Feature Vaillant Worcester
Quality of materials 9.5/10 (plus range) 8.0 (CDI range)
Reliability 8/10 9/10
What installers say 9/10 "easy to work on" 6/10 can be expensive & a nightmare to repair
After Service 8/10 "Vaillant are very responsive" 8/10 "Worcester look after their customers"

 

Vaillant is the overall winner!
