My hydrogen boiler! - How the home hydrogen fuel cell boiler works. Viessmanns Vitovalor!

We wouldn't be heating geeks if we didn't live and breathe it! Interested in hydrogen boilers? See and understand how the Viessmann Vitovalor hydrogen fuel cell boiler works.

Hey man, less background music when your actually talking - purely constructive criticism otherwise good video and very informative Thankyou :)

[sauloost]

Great video, thanks for making it. Planning to do my MSc thesis on the topic of the capability of fuel cells in homes to balance the eletrical grid. This video has helped me understand the tech a bit more!

[grumpygit]

Have only seen your videos on heat pumps and this is a refreshing one Would like to see one with an updated system

[Kiyarose]

You could feed that CO2 into a Photo Bio Reactor( PBR) and waste water( for Algea feed) to grow Algea that permanently sequesters 1 Ton of CO2 for every Barrel. Also many products can be made from Algea, Carbon Negative Algea Bio Fuel, Nutraceuticals( as Algea is rich in Omega3), Soil conditioner, Compostable Flip Flols & Surf Boards etc.

Great video, really interesting. I didn't know you could buy stuff like this for your house.

[dandan-yhmy]

Yes. Been waiting for new content from you sir, look forward to it.

[ParkesPlumbing]

Awesome guys, I did the training on the vitovalor at viessmann and it was excellent.

[richardmarkham]

Not heard of these before I watched you talking with Skill Builder. (Oct 2023).

Interesting technology.

Your power generation looked like it was 24/7, so that means it's 'burning' gas 24/7. How much heating output does it produce to keep the electricity generation going? I assume it doesn't modulate generation? So it's either on at 16kwh per day or off (or cycling). Does it run 24/7 and have just enough heat output to heat up the HW cylinder twice a day? So in Summer with no CH on, is it still generating electricity 24/7?

Also how does it compare to a Sterling engine gas boiler?

[HeatGeek]

Interestingly the most current and efficient gas fired power stations are producing 520g co2 per kwh of electricity. These produce 220g! What do you guys think of the Vitovalor? Interim tech or not moving in the right direction?

[TomBray-LowCarbonLifestyle]

This is really interesting, and seems to make sense in terms of cost of power / heat etc. My worry is that for 2 kW of gas you produce 0.75 kW of electricity and 1 kW of heat... less than 90% efficient. And in terms of CO2, you are using over 40 kWh of gas to generate your 16.7 kWh of electricity each day, at a CO2 intensity of 0.183 kg/kWh (natural gas) and a grid electricity rate of 0.233 kg/kWh you would be using almost double the CO2 intensity electricity compared to electricity supplied by the national grid. And using lots of gas all year round.

It is definitely an interesting piece of technology, and from what you suggest works out economically, but putting the carbon dioxide story into this.... I start to worry.

Feel free to correct my understanding...!

Another great video Adam, well done 👍

Does this work on a feed in tariff. Would you use this system with battery storage?

[davidmarsden]

Great video, very informative but spoilt by the unnecessary background music

[UrbanPlumbers]

Never knew a system like this existed. As Sheldon Cooper would say: 'interesting'.

[TheRobostevo]

Is there a simple way to explain heat loss calculated in KW? For example heat loss of 7kw with in your property? Interested in the design aspects of heating systems as we do install some interesting stuff how ever we do not design it.

[ismscsim]

Is there RHI for this?....looks very interesting

[wiezyczkowata]

what's the cost of using it year round?

[DjChronokun]

neat, can systems like this be used cost effectively with gas delivered by cylinders? or only if it's supplied by pipe?

and could something like this be used in conjunction with a battery system to give it more peak power output for running off grid or supplying power during a power cut/blackout?

[dayplumbingservices]

Great video, thanks . what kind of training is available for that kind of install ? manufacturer training? or other training? ( I am gas domestic)

[seanhill]

is the hydrogen separated from the natural gas just before the boiler
how is is this done some filter or catalyst what ihappens to the left over gas and what is it make u p
intriguing but very cool technology
