Benefits of Viessmann combi boilers
A Viessmann combi boiler cleverly combines an energy-efficient central heating system with a hot water heater in one sleek unit.
All of the combi boilers in the range are rated Energy efficiency class A and are a popular choice for modern UK homes.
One of the common reasons cited by customers who have chosen a combi boiler is its size. These are excellent space-savers which make them ideal for small properties, or homes where you want to utilise areas like the loft or airing cupboard for other things.
Combi boilers also work on demand, switching on as needed to deliver hot water to your taps or radiators.
- Comprehensive warranty provided as standard
- No loft tank or water cistern needed
- Works at mains pressure
- Compact size makes it an unobtrusive addition to most homes
Combi boilers are not only good for saving space and energy, they’re a good choice for saving money too. Obviously the initial purchase cost will vary from model to model (and from one manufacturer to another too) but the key is to ensure you get the right fit for your home not just now but for years to come too.
Viessmann boilers have a comprehensive warranty as standard, so that helps with ongoing maintenance costs. Lastly, don’t forget to budget for having a reputable and qualified engineer install your new boiler system. Get free quotes for a new Viessmann boiler today.
Benefits of Viessmann regular boilers
Now you’re thinking about investing in a new boiler, you’ll be realising that there are various different types of hot water and heating systems to consider. If you have an older property, or if you are replacing an old boiler system, you should think about the benefits of a regular or traditional boiler – also known as an open vent boiler.
These are only similar to the systems of yesteryear in that they comprise a separate cold water tank (in the loft) and a hot water storage cylinder as well as the actual boiler itself. That’s where the similarities end though as modern regular boilers such as those from Viessmann are much more energy efficient than their predecessors and offer plenty of advantages for modern living. Viessmann’s regular range offers a choice of options.
- Gives you improved energy efficiency compared to older boilers
- No need for extensive pipework changes if you are replacing an old regular system
- A good choice for homes where demand is particularly high and/or water pressure is low
- Copes with multiple bathrooms or ensuites, even if used at the same time
- Warranty included as standard

Benefits of Viessmann System boilers
If you have space for a hot water cylinder and want to benefit from energy efficient hot water and heating, a system boiler from Viessmann could be just what you’re looking for.
Unlike a traditional or ‘regular’ boiler, the system boiler doesn’t require an additional cold water storage tank – which is the part that most people have to house in their loft.
With a system boiler, you simply have the main boiler unit plus a sealed hot water storage cylinder.
This set up typically gives a higher hot water flow rate than a combi boiler and can cope with higher demand – which suits larger households.
Viessmann system boilers are rated class A for energy efficiency so if you are keen to make a greener choice, this type of system makes sense.
- Ideal for high usage i.e. if you need to deliver hot water to more than one bathroom
- Compatible with other Viessmann solar thermal systems and low carbon technologies
- Comprehensive warranty provided as standard
- A constant supply of hot water whenever you need it
- Viessmann system boilers offer excellent energy efficiency

Viessmann Oil Boilers
The Vitorondens 200-T is a floor-standing oil-condensing boiler which features Viessmann’s bespoke two-stage Vitoflame blue flame condensing oil technology and weather compensation as standard.
Viessmann introduced the high efficiency oil boiler to the UK in 2018 in light of the tightening regulations on oil boilers and carbon emissions. The UK government is planning to phase out the installation of oil boilers by 2025; Viessmann are positioning the Vitorodens 200-T as an alternative to biomass and LPG boilers for off-grid customers and where renewable options aren’t always ideal e.g. in older and less well insulated buildings which need a high-temperature heating system.
The Vitorondens boiler complies with the OFTEC requirement for maximum flue gas NOx emissions of 120mg/kWh, which came into force in September 2018, and will meet the even lower NOx emissions levels expected to be legislated in the next five years.
The Vitorondens 200-T comes has its own Viessmann Vitotronic 200 control unit and will also work with the Vitoconnect communication system that allows you to control your boiler remotely via the Vicare app on a smart device.

Viessmann Boiler Warranty
Every boiler manufacturer offers a standard warranty with their boilers which last between 1-10 years. The warranty is your insurance policy and means if a fault develops the manufacturer will resolve it within a specified time frame. Some warranties include both parts and labour while others may only cover parts. The most important thing to remember is to get your boiler serviced by a Gas Safe registered engineer every year as failing to do so is likely to invalidate your warranty. For more detail about this brand’s warranty (including the small print) take a look at Viessmann Boiler Warranty.
Viessmann Boiler Repair Advice
Even the highest quality boiler can develop faults and problems as they age. Some are minor issues you may be able to handle yourself but most will need a Gas Safe registered engineer to diagnose and repair the problem. To find out if there are any common problems associated with this manufacturer you can read our guide to Viessmann Boiler Repairs & Common Viessmann Boiler Problems.
Viessmann Error Codes
Error codes may appear on your boiler’s display; it’s your boiler’s way of telling you that something is wrong. Each manufacturer uses a different coding system to help an engineer to diagnose a fault. In some cases it may be a simple issue such as low pressure which you can adjust yourself but more technical faults will certainly need a professional. We’ve put together a list of error codes for all Viessmann Boilers to help you understand what’s wrong before you contact an engineer.
