This boiler is very good . Saves money. Our old boiler was using £2 per hour. This uses 6kw 42p an hour. Hold both water and heating button 3 secs. Then info then boiler . Range rate max power usage to 50%. Job done.
In your video you mentioned it should be showing max output at 30kW not 24kW. The reason is because the central heating output is 24kW, the 30kW part is the hot water output, hence why it's called a 30kW model.
Yay, a positive comment! Makes a change from complaints about materials and build quality. Can't say I have any real complaints as an end user so far, other than I had to "reboot" it a couple of times when it randomly decided to deliver lukewarm water but that hasn't happened in months now.

Your heating is controlled by the main house thermostat. Why would you turn on the heating if just one radiator is open (which is part of plumbing design for house heating)
Got the easycontrol ct200 and my heater is staying on all the time. I changed the temperature and everything still stays on. Only way to turn it off is to disconnect the key o the termostat.
Had one installed yesterday. No thermostat or heating controls installed yet. How do you turn the heating on/off at the boiler? Frustrating as currently the heating comes on when we don't want it to so set temp at 30 degrees. Rads still get warm though. Following on from the above. You need a separate control panel which turns boiler on/off, set timer etc. This was installed by an electrician a few days after the boiler was installed

Hi, I had one recently installed. It’s quiet as a mouse when the heating is on but when the hot tap is on the boiler makes a crackly/spitty type noise but there are no leaks anywhere?
Hi. Have you made much use of the 'Quick Tap' feature? It supposed to help save water when you want hot tap water. Just wondering if you find it effective? Many thanks.
I've tried it, but I'm not sure it makes much difference. Typically the hot water isn't taking too long to come through anyway so it's not needed much, especially if someone used hot water in the last half an hour or so and there is residual heat in the heat exchanger.
Very Good. The electronic water softener works by using a magnetic field to alter mineral crystals inside the water. It is a mostly untested technology that gives mixed results. They are somewhat similar to water descaler in principle. They modify mineral crystals instead of replacing them with salt.
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.
It's strange because I don't find ours to be on obnoxiously loud. It's only behind a thin cupboard door. I haven't noticed water flowing noises particularly. The main new noise is the whirring and clunking of valves when it switches between heating and hot water modes.
@@RobFisherUK Its settled down now, noise isn't an issue. The issue we are having though is hot water to the taps takes an age. Its fine for showers and baths, but for the taps, it seems to take forever.
@@orpheusjones7313 seems odd. Once you turn on the tap it should fire up within a few seconds, heat exchanger should get warm in 10 seconds, and after that it's just how long it takes the water to get to you. I tend to not turn the tap on full blast straight away to make it easier to heat the heat exchanger. But it shouldn't make that much difference. I'd just check it's actually firing up when it is supposed to.
@@RobFisherUK Thanks, it fires up because you can hear the flame. The installer did change some settings, like 0 second delay to switch between hot water and heating, i wonder if its that? Either that, or i'll have to get them back in, 50 seconds for warm water from a tap seems too long.
@@orpheusjones7313 the only other setting I remember is the delay before switching heating back on after using hot water. I'm sure it prioritises hot water however you set it up. You say the shower works fine but the tap doesn't. If they're next to each other I can't see a reason for it. A tap in a different location might just have a longer pipe run. Otherwise, yes, might be worth asking the installer.
Bob how do you turn the heat on/off by the main boiler. i.e just turn the heating on and turn it off ? I find the wireless thermostat hard to set and can only turn heat for 1 hour by pressing the booster button
If you can't be bothered with the (presumably Hive) thermostat, just try to get it into manual mode. Then it behaves like a normal thermostat. I don't think you can really control the heat from the boiler panel.
My new 4000 boiler is making continuous noise whenever we turn the hot water tap on. it is so loud, it disturbs anyone sleeping anywhere in the house. It is much louder than a boiler should be. Even my previous 15 years old boiler didn't make this much noise.
Interesting, thanks. I just went and read an article about it. I'll check the settings later. I have 6 radiators. 9kw sounds pretty low, though. I guess the boiler will just run for longer at that lower output, but overall that works out more efficient. Does that sound about right? Presumably there's no harm in experimenting.
If you can remember your old back boiler model and check the specs typically, it would of been set mid range usually 3 settings between 8 12 15kw depending on the heat loss of your property 9kw wouldn't be far away you'll be surprised. Plenty of apps and tools online to work out the property hestloss calculation 👍
Currently depending on the temp it will ramp upto 24kw and modulate down to the required output depending on flow temp and room temp cycling on and off. Range rating will cut down on the cycles and save on your energy bills
@@RobFisherUK 9kw is the average in a house , I think you can only turn it down by 50% though , ie 12kw. It’s more efficient to rate the boiler to match the heating requirements. Did you do it after ?
That's the main thing missing from this video. I have the Hive thermostat. The noise when it's just heating is quieter than max hot water flow. You don't really hear the heating pump and it's putting out less power just for heating. There are a few extra whirrs as valves change position when switching between hot water and heating.
Hi Rob, I'm desperately trying to work out how to switch the heating off on mine! We have the Easy Control and have turned everything down to 5c but still seems to be heating radiators etc. I just wanna turn it off completely as its still using about £5 per day. Any ideas?
I have the Hive controller so I don't have any experience of it. But if you turn the heating off and radiators are still warm that could be an installation problem.
All fine. It's needed a "reboot" twice, where it seemed to not want to deliver full power and showed an error code about a temperature sensor. But turning off and on again fixed it and it hasn't happened again for months. First service is coming up soon; not expecting any trouble.
Yes. The limitation is your mains water pressure. Ours isn't particularly high so the flow reduces noticeably from each tap when running multiple taps but that's the case with the cold water, too, it's nothing to do with the boiler.
My housing association put me one of these in a few months ago. I'm on a water meter and my recent bill shows my consumption has increased my bill by £60 a year! I preferred my old boiler which was so much cheaper than this, it's ridiculous!
I'm not totally sure how the boiler affects the water usage. Do you find you have to run the tap a lot more to get hot water? If so, you can run the tap for a few seconds and shut it off. This should tell the boiler to start heating. Give it a few seconds to heat up and then turn the tap back on.
Riverside have put me one in to and I'm ready for ripping it off the wall bring back my old one without all this wifi shite on the wall I preferred my dial now heating is coming on when it's off on thermostat but boiler is heating up and heating on I don't know how to get it off !

I had one of these fitted a few weeks ago by BOXT - I live in an open plan maisonette in a conversion and the boiler is on a party wall - that fan noise each time you turn the tap off or the heating stops is quite loud on my boiler - I really don't want to disturb the neighbours - does anyone know if there is a way quieten the fan or shorten the length of the overrun or better still turn it off completely - I am thinking of getting an independent engineer in to optimize the settings, etc. because BOXT and Worcester Bosch have not been that helpful - the boiler was good value but I guess they cut corners quite a lot to keep the price down

I'd talk to your installer. Maybe it's an option in the service menu somewhere or maybe it's trying to tell you something's wrong. No beeps from mine, anyway.
Hot water discharge is horrible. You open the tap and it immediately scolds your hand even with preheat setting turned off.
Can't you turn down the hot water temperature? Presumably you don't have mixer taps?
@@looktothefuture84 Apparently, yes you can reduce the temperature of the hot water that comes out of your water taps.
But you have to do it through the controls on the boiler itself.
The Boiler's instructions manual should tell you how to do this.
I hope this helps you.
This is for the Worcester Bosch Combi Boiler Greenstar 4000 Model.
I also have one of these Boiler's that was recently installed in my home to replace my old boiler that was 17 years old.
