Data Centre In The Shed Reduces Energy Bills To £40
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
An Essex couple have become the first people in the country to trial a scheme that sees them heat their home using a data centre in their garden shed.
These three introductory paragraphs add some detail.
Terrence and Lesley Bridges have seen their energy bills drop dramatically, from £375 a month down to as low as £40, since they swapped their gas boiler for a HeatHub – a small data centre containing more than 500 computers.
Data centres are banks of computers which carry out digital tasks. As the computers process data, they generate lots of heat, which is captured by oil and then transferred into the Bridges’ hot water system.
Mr Bridges, 76, says keeping his two-bed bungalow near Braintree warm was a necessity as his wife has spinal stenosis and is in “a lot of pain” when it gets colder.
I think this simple idea is absolutely brilliant and very technically sound.
Here are some further thoughts.
It Would Be Ideal For A House Like Mine
My house is a modern three-bedroomed house with a garage and when I asked Google AI how many UK houses had garages, I received this answer.
Approximately 38% of dwellings in England have a garage, according to a 2020 report. While a specific UK-wide figure is not available, extrapolating this percentage to the total number of UK dwellings suggests there are over 10 million houses with garages, though the actual figure may vary across different regions.
Looking at the picture in the BBC article, I feel that this HeatHub could fit in my house.
I would expect that any house with a garage, a small garden or a big enough boiler space could accommodate a HeatHub.
Obviously, the house would need.
- A boiler, that provides heating and hot water.
- A good broadband connection.
My house has both.
Would My House’s Heating System Need To Be Modified?
It looks like it’s just a boiler replacement, so I don’t think so, but it may need to be moderbnised with digital controllers to get the best out of the system.
Will There Be Other Systems Like Thermify’s Heat Hub?
Some of our electricity suppliers seem very innovative and the market is very competitive.
Would they just sit back and let coompetitors take their customers? I doubt it!
So I suspect there will be other systems, each with their own features.
I have already, written about heata, which uses similar principles to give affordable hot water in British Gas Partners With heata On Trial To Reuse Waste Heat From Data Processing.
The BBC article gives some examples of data centres used to provide heating, so it is worth reading the full article.
Better Than A Kick In The Teeth – As C Would Say!
I’ve just had an e-mail from OVO Energy, who have been my energy supplier for at least eight years, that they are going to reduce my Direct Debit by £26 per month.
OVO didn’t give a reason, but then it dawned on me.
In I’m Getting A New Hydrogen-Ready Boiler, I laid out my reasoning for getting a new boiler, as the pump had failed.
It’s only been one billing period, but I suspect other factors have kicked in.
I asked Google AI, if the the efficiency of gas boilers increased in the last ten years, and received this reply.
Yes, gas boiler efficiency has significantly increased in the last ten years, with new models achieving efficiencies over \(90\%\) compared to older ones that could be as low as \(60\%\). This is primarily due to the mandatory use of condensing technology in new boilers, which recovers and reuses heat from exhaust gases to preheat water.
As far as we know, Google are not in the gas boiler business, so I’m sure their answer is unbiased.
It looks like I shall be saving £312 per year, because of the new boiler.
Thus, if it lasts ten years, which is the guarantee period, then it has paid a substantial part of the cost of the new boiler.
As my late wife, C, would often say, that is better than a kick in the teeth.
Should You Get A New Boiler?
I am not qualified to answer that, but I’m you know a man or woman who is!
I’m Getting A New Hydrogen-Ready Boiler
The pump in my current nine-year-old boiler has died and it needs to be replaced.
The plumber gave me two solutions.
- Put a new pump in the old boiler.
- Replace the boiler with the current version of the old boiler.
Note.
- The plumber said the new boiler would be hydrogen-ready.
- I seem to remember the same pump failed before.
- The pump had failed because of a water-leak into its electrics.
- Was the previous failure of the pump caused by the same water-leak?
- Fitting a heat pump in my house would probably cost more than I could afford.
- The new boiler would come with a ten-year guarantee.
As an engineer, I can see the following scenarios for heating my house and providing hot water.
1. Keeping Calm And Carrying On
This means that the current arrangements for energy continue.
- There would be no compulsory heat pumps.
- There would be no change to any of my hardware, after installing the new boiler.
- I would continue to get gas for heating and hot water delivered through the mains.
The new boiler solution should give me ten years of reasonably trouble free-running, so long as the gas was natural gas, hydrogen blend or hydrogen.
2. Keeping Calm And Carrying On But My Energy Supplier Switches My Gas To 20 % Hydrogen-Blend
This means that the current arrangements for energy continue.
- There would be no compulsory heat pumps.
- There would be no change to any of my hardware, after installing the new boiler.
- I would continue to get gas for heating and hot water delivered through the mains.
- The gas pipe into my house would have to be checked for compatibility with hydrogen-blend. But then I encountered no problems when switched from coal-gas to North Sea Gas around 1970.
The new boiler solution should give me ten years of reasonably trouble free-running, so long as the gas was natural gas, hydrogen-blend or hydrogen.
3. Keeping Calm And Carrying On But My Energy Supplier Switches My Gas To 100 % Hydrogen
This means that the current arrangements for energy continue.
- There would be no compulsory heat pumps.
- There would be no change to any of my hardware, after installing the new boiler.
- I would continue to get gas for heating and hot water delivered through the mains.
- The gas pipe into my house would have to be checked for compatibility with hydrogen.
The new boiler solution should give me ten years of reasonably trouble free-running, so long as the gas was natural gas, hydrogen blend or hydrogen.
4. Switching To Some Form Of Heat Pump
- This would mean that I would go all electric.
- My house is a concrete lump and a guy I trust, said it would be difficult to fit a heat pump.
- I am suspicious of scientific and technical solutions proposed by politicians.
I’m not saying, I’d never use a heat pump, but I will take a lot of convincing.
5. Switching To Some New Form Of Electric Heating
I have seen two companies, which use the excess heat from a data centre to heat water for central heating and/or hot water for domestic needs.
- heata is a spin out from Centrica, that provides hot water and saves you money on your utility bill.
- thermify is a startup from Wales, that replaces the gas boiler, with an electric one.
There are probably other similar systems under development.
From my knowledge of computing and electrical engineering, I believe devices like this could be new form of cost-efficient electric heating.
Because my house has three-bedrooms, I would need a thermify, for both heating and hot water, but a heata working in tandem with my gas boiler could probably keep me in hot water.
I would feel that large blocks of flats or offices could have a data centre in the basement to provide heat for the building.
I would also suspect, that there are other devices out there, that work on different principles.
My Decision
I’m fitting a new boiler, as that should give me ten years’guarantee-backed and trouble free running and future-proof me for all possible government decisions, except saying that everybody must fit a heat pump.
When, this new boiler pops its clogs, i would hope, that some clever engineers have come up with a plug-compatible electric replacement for the new boiler I am about to have fitted.
Tiny Data Centre Used To Heat Public Swimming Pool
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The heat generated by a washing-machine-sized data centre is being used to heat a Devon public swimming pool
These three paragraphs outline the story.
The computers inside the white box are surrounded by oil to capture the heat – enough to heat the pool to about 30C 60% of the time, saving Exmouth Leisure Centre thousands of pounds.
The data centre is provided to the council-run centre free of charge.
Start-up Deep Green charges clients to use its computing power for artificial intelligence and machine learning.
Note.
I find both of these interesting applications.
The Neighbourhood Leading A Green Energy Revolution
The title of this post, is the same as that of this article on the BBC.
These are the first two paragraphs.
An ambitious target of using hydrogen to partly power homes in the UK within three years has been set by the National Grid, the BBC has learned. On the east coast of Scotland, a small neighbourhood is playing a key role in this energy revolution.
From next year, about 300 homes in Buckhaven, and Methil, in the area of Levenmouth, will be powered by green hydrogen gas in a project called H100. Customers will be offered free hydrogen-ready boilers and cookers in the scheme, which will initially last five and a half years.
I described the H100 Project in ‘World First’: SGN Launches Bid For 300 Green Hydrogen Homes Project In Fife.
This is the home page of the H100 Fife project web site.
This Google Map shows part of Buckhaven.
Note the wind turbine, that will produce the hydrogen is in the South-East corner of the map.
Is Thermify The Ultimate Zero-Carbon Boiler?
In The Sunday Times today, there is an article, which is entitled Tech Is Putting Net Zero Within Reach, which lists several ideas to help us achieve net zero.
The first is the best idea, that I’ve seen this year.
When you talk using a phone, tablet or computer to your family, preferred social network, bank or company, you are probably talking to or through a server somewhere on the Internet.
These servers are often a bank of computers and they use a lot of electricity and give out a lot of heat. So they are often located in unusual places like Iceland. Someone has even suggested putting them deep under the sea.
Under a section entitled Computer Power, the article in The Times introduces Thermify.
The Welsh company has combined a computer server with a heat exchanger to replace your gas-fired boiler.
I suspect all of these servers fit together just like data centres do all over the world.
It would be ideal for my house, as I only use gas for heating and hot water and I have solar panels on the roof and under-floor heating using hot water.
I shall be contacting the company next week.
Green Hydrogen Searches For Industrial Outlets
The title of this post, is the same as that of this article on E & T Magazine.
It is a detailed look at the uses for green hydrogen.
A few points from the article.
- Like fossil fuel hydrogen can store energy for months.
- Less that 10 % of green hydrogen will be used for energy storage.
- Hydrogen has a poor round trip efficiency, if you create it with an electrolyser and then convert it back to electricity using appropriate technology.
- Heavy transport may account for 25 % of the use of hydrogen.
- Industrial and home heating applications could account for the use of another third.
- One of the biggest uses today of hydrogen is in oil-refining to make low sulphur fuels.
- Steelmaking could be a big user, but there are many different methods and some have problems.
- Cement making could be a good use of green hydrogen.
The article is a must-read and it makes you think.
OVO Energy To Lead Major Zero-Carbon Heat Trial
The title of this post, is the same as that of this article on Current News.
These initial three paragraphs explain the project.
OVO Energy is to lead one of the UK’s largest ever zero-carbon heating trails, thanks to a £4.2 million grant from the government.
Kaluza, Sunamp, Retrofit Works and Parity Projects will work together with OVO Energy to install and operate zero-carbon heating systems worth up to £15,000 in 250 homes.
Mitusbishi’s Ecodan air source heat pump and Sunamp’s thermal batteries will be installed in the homes, creating electric, zero-carbon heating systems. Additionally, the homes involved will have up to £5,000 worth of energy efficiency improvements made.
That sounds like a sensible project to me, as we need to be zero-carbon in everything we do and heating is the largest source of emissions in the UK with twenty percent.
