- In this review of the Worcester Bosch 4000, we review the latest Worcester Bosch 4000 combi boiler with Allen Hart. The Worcester Bosch 4000 is one of Worcester Bosch's most advanced combi boilers that features an easy-to-use digital display, high efficiency, and a more compact design.
Fantastic guys. This video was so informative that I have just purchased one and looking forward to my insterlation |Tuesday 23/07/24 ..
That's great to hear Mark!
Good video, Thanks for coming.
Thanks Allen, it was great to hear your thoughts on the 4000!
Learnt so much from this ordering one from you today!!
Hey Mandy, glad you found it useful - thanks for watching!
Very good informative video I own an 42cdi classic very pleased with mine so far .
Certainly no plastic in the packaging. It's all used inside the boiler
Thanks guys you are very knowledgeable bunch and that’s appreciated. Recently attended this training. About to purchase a Bosch unit for my house and came upon your video.
Aurora colorado viewer here. Greeting’s amigos.
Great to hear from you all the way from Aurora Colarado - thanks so much for the feedback! Are you looking at purchasing the Worcester Bosch 4000?
@@Heatable You’re welcome ! Yes I’m purchasing a Worchester 4000 today. I recently signed up for abc program at Bosch thermotechnolgy from Bosch.
I’m looking to start offering this product instead on navien, rheem, or others. Recently attended specific training on this product and will have more training trough the year.
You guys are awesome! Keep the good work going.
@@pacificairsystems9683 It's definitely worth having the training if you're looking at potentially offering it to customers. Also, don't forget to subscribe if you like the videos!
Just had ours installed. Why is it so loud? Not only the general sound of the boiler, but also the noise of water flowing through the pipes? One of the selling points of this boiler is that its meant to be quite. How is it that boilers 15 years ago made less noise? The old baxi we had would switch off immediately after turning off the tap. This takes about a minute. Having just spend thousands of pounds, i'm not sure what to do.
How do you switch the bloody thing off? My Comfort plus II rf thermostat has failed and I can't get the heating off.
Good video lads. Impressive how low the thing modulates to. Would have liked to have heard some info on the weather comp control side of things. Good video nonetheless, i would consider this as a replacement when my greenstar classic kicks the bucket.
Cheers Rodger. For your sake, we hope it doesn't kick the bucket too soon.
im getting one of these installed in a few days. old boiler was a good 25 years old and has provided no heating for going on 4 years
Hey, thanks for the comment! How come you waited 4 years to get a new one?
@@Heatable it took me that long to save for one along with installation costs. If my mortgage hadn't doubled then it would have been sorted a few years ago
Any improvement on the flow valves that continually pinhole
I’ve come home, and brushed against my radiator and it’s on. I’ve just had this boiler installed. I don’t know how to turn heating off. I just want hot water. Alan where is the vid for the controls…I really enjoy these vids, making me want to become an installer, at 47 another career change is out of the question though.
Hey Kate, what control do you have?
hi..what do i do if the mains pressure is not that great and dont have the space for a cylinder for a system boiler?
It feels very much like Worcester Botch watched one of Allen's old videos then decided to copy the layout of a old Baxi boiler with everything in the correct place to gain easy service access.
I hope that the Worcester Botch training and product course didn't lobotomize Allen and now he praises the hell out of Worcester Botch's products. I would never choose another Worcester Botch product on principle alone.
As a victim of previous sales hype and my terrible experience of having one of their combi boilers, I would never
pay good money again to that company.
Great video, I was totally sold on a Veissman 100 as the modulation ratio is impressive and Wochester don’t market their ratio anywhere, so I had no idea it could modulate down to 3KW. I currently have a Baxi Platinum which has a manual adjustment down to 10KW which is way too much for my house.
It's definitely one of the best features, the 4000 could be a good option if your current 10KW is too much!
I have the 4000 15kw System boiler and it modulates down to 1.9kw. When it's about 10C outside that's what it ticks over at.
OK if you live in a one room flat, but 3Kw won't be of any use if you live in a 3 bedroomed house.
@@Gary-Seven-and-Isis-in-1968 of course it will….on milder days you can keep a 4 bedroom house at 21degrees with 3kw. It’ll take more to get it to 21 but once there all you need is to replace the heat lost. At -2 outside my house needs about 7kw to maintain 21degrees.
What I would like to know and I have asked the same question even Worcester no replies yet the wifi easy control that comes with a table mount and a wall mount the table mount is pre wired to the 13amp plug and the wall mount comes with a 13 amp plug but the wall bracket needs to be connected, the question is does the wall mount have to be wired to the plug or to the boiler. Withe the RF wifi key . If it as to be wired to the boiler how does the table mount work .
Hey, the Bosch Easy Control thermostat requires a direct hard-wire connection to the boiler when it's mounted on the wall. However, if you're using the Easy Control on its stand, it doesn't need to be hard-wired. This is because the stand includes a specially designed transformer built into the plug, allowing you to simply plug it into a standard electrical outlet for power.
7:30 I'm still not convinced about range rating: why would I care about setting the max output if it's automatically going to modulate down anyway as soon as it detects the flow temperature rocketing up?
For that matter, I'm not sure why cycling is bad. 6kW at a 50% duty cycle is surely identical to 3kW.
Hey Rob, thanks for your comment. Range rating sets the upper limit for your boiler, ensuring it doesn't operate beyond what's needed for your home, which can improve efficiency and reduce wear. While modulation adjusts the boiler's output within that set range based on real-time demand, range rating ensures the boiler's top-end is appropriate for the property. Regarding cycling, frequent on-and-off actions can wear out components faster and can be less efficient than steady operation. While 6kW at 50% duty does provide the same average output as 3kW, the continuous operation at 3kW offers more consistent heating and can be more efficient.
@@Heatable Many thanks. It sounds like what we're doing with the range rating/max output setting is giving the boiler a clue as to what is likely to be needed so it doesn't start out full blast unnecessarily. As a computer programmer I can imagine automating this by giving the boiler a memory and having it learn how the CH water temperature responds and remembering for next time. But that's because I like to over-complicate things!
Good video thanks
Question for heatable, Allan or any experts. I had this boiler installed last April from British Gas and nothing but problems. The PCB board had to be changed after six months but the major issue that can’t be fixed is the flue leaks from the outside. British Gas state this is normal for a condensing boiler but my old boiler was condensing but never leaked. Worcester state it shouldn’t leak and not been very impressed with their follow up as they sent an engineer that stated there’s a fault but there’s not but he can’t find the fault. Should the flue leak?
Hi Dev, sorry to hear you're dealing with this. You're correct, your flue shouldn't be leaking. We recommend you get in touch with a reputable local installer for a second opinion to see if they can find the issue.
@@Heatable thanks for your quick reply on this
@@devbhari5480 Hope you get it sorted!
Hi heatable no it’s got worse as British Gas are now insisting a plume kit be fitted. Worcester we’re going to send a senior technician but based on the advice of a plume kit from British Gas have confirmed a plume kit is the only way forward. I’ve asked Worcester directly should the flue leak and they will not answer the question. Really bad from both
@9:06 you say the 4000 will fit on the "I junior jig" the 4000 will not, as the I junior has 2 small hooks at the top the 4000 has one central hook, its the screw fixing footprint that is the same. (but you get the jig with the boiler). 14:55 the gauge in the boiler is NOT for the customer, as will break the combustion seal. (could not see the easy control as an option on your website?). you can install the PRV pipe via the new jig before hanging the boiler - I have never had any issues. good video tho very informative :)
Hi Daz, appreciate the helpful feedback. In future videos, we'll try to be more accurate when it comes to fact-checking.
@@Heatable keep up the good work tho :)
I am from Kashmir india How much does it cost fully here
Ahbal 😂
@@adelfaragalla3621 i need it can someone help me to get it
But no Opentherm.
Can someone please advise. Ive just had thos boiler installed the 30kw and the engineer did no range rating. Ive had a play myself and can see where i need to go to do it. I got a question - the way i see it range rating limits how fast/hard the boiler works to get the CH up go temp. So being lower it will get to the desired temp but at a slower pace. Am i roght in thinking this? If so its saying on electric rather than gas? Can someone please tell me a rough guild on what percentage you would range rate for a semi detached 3 bed with living room, kitchen & conservatory (9 double rads in total)
In this day and age i want to get the best out of my boiler and saving on the bills.
Another thing i was thinking if you could range rate it to the lowest and turn the CH temperature up high does this kind of counter balance it? Im probably looking at it wrong but i just want to know, understand and get the best out of it. The CH is currently set at 60% and 60°c, rads are not boiling hot to touch but are okay for now, but come the colder weather do i turn up both range rating and temp.
Sorry for the questions
Thanks
Hi Christopher, range-rating your 30kW boiler means adjusting its maximum output to suit your home's specific heating demands, which can result in energy savings by preventing the production of excess heat. A lower setting will cause the boiler to heat up more slowly, and while it does affect gas consumption, it won't save on electricity unless you're dealing with an electric boiler or an integral electric pump.
For your semi-detached 3-bedroom house with a living room, kitchen, conservatory, and 9 double radiators, a rough initial estimate for range rating could be based on the guideline of approximately 1.5kW per radiator, which would mean a starting point around 13.5kW or 45% of your boiler's capacity. However, the ideal percentage for range rating is really determined by the house's specific heat loss, which can only be accurately gauged with a professional assessment considering factors like insulation quality, window types, and radiator sizes.
The current setting of 60% range rating and 60°C temperature might be fine for the current weather, but as temperatures drop, you'll likely need to increase both the range rating and the boiler temperature to maintain comfort. It's not very efficient to just turn up the CH temperature with a lower range rating; instead, it's better to find the right balance between range rating and flow temperature. The boiler should operate at the lowest possible temperature while still providing comfort, which not only saves energy but also maintains the efficiency of your condensing boiler.
When adjusting your boiler, observe how well your home maintains heat at the lowest setting that is still comfortable. Incrementally increase the range rating if necessary during colder weather. Also, make sure to keep the return temperature substantially lower than the flow temperature to confirm the boiler is running efficiently.
@Heatable thanks for the reply. Last question when looking at the range rating the highest percentage it goes up to is up to 80%. Is this correct?
@@sidboi19 This depends on which boiler you have?
@@Heatable it's the worcester 4000 30kw
@@sidboi19 Yes the highest rate range for this boiler would be 80%!
"It's a good choice in a move towards going greener" really mate???! 12.5 litres at 35 degrees????? What he means is that it can increase the incoming water temp by 35 degrees at a max flow rate of 12.5 litres per minute. Don't get expert advise from a plumber, get it from a recommended heating engineer, heat geek engineer map can help.
Do not buy a 25Kw as the output of hot water is only 9 litres per minute, you can hardly shower. Total disgrace!
I have a 25 KW and the hot water is really fast at heating and very hot - better than the Baxi duo-tech - I am here just to find out how to turn the damn thing down because the radiators are too hot too and the boiler makes a noise like a plane taking off - I've already adjusted the setting to 50 for heating and 53 for water
@@DrBiohazard Did you figure out how to stop the excessive noise? We've just had ours installed and its far too loud in my opinion.
Yeh, I got rid of some of the noises but it still sounds like a vacuum cleaner, especially when the heating stops or a tap is turned off - if you go to the service menu by pressing the rad and tap at the same time then go to settings>Heating>Max heat output - the % output can be lowered if you only have a few radiators - hope this helps@@orpheusjones7313
My parents have an electric shower, so the 25kW would be ideal for them as they only need hot water for hand and dish washing.
Boiler replacement is a rip off like for like is £1,200 plus just to fit it lmfao, he was trained on this boiler how by connecting a few pipes lmfao
Installing a boiler safely involves more than just connecting a few pipes - gas safe exists for a reason!
That's not a review. It's a sales pitch. Do not buy what he is saying. Trust what customers have to say.
Think your face is telling a different stories to what's said
We’ll work better on our facial expressions for next time
My Worcester Bosch 30 CDI is causing me financial hardship, no question! Heating engineer due on Monday 9.01.23, maybe he should become a lodger! ,
Alan just standing there looking bored not interested in what that dude is saying.
we'll tell him to look more interested next time 😂
