Worcester Bosch ECO button - what is it and what does it do?

[@RPKGameVids]

The eco button will always be 'on' on my boiler from now on, thanks for the information!

[@AlabamaTree]

Thanks for this. I was always wondering why the boiler was starting up a few times a day on its own.

[@mazwooding2621]

That was inspirational! :D That was I was looking for as well. Simply perfect! You save my family this winter from freeze to death. Thanks bro :)

[@stuartsinclair6269]

Yes, I’ve timed mine, with it off the kitchen tap takes 8seconds to get hot water, put the button on it takes 18seconds, so always mine is left off in the long run it’s better saves you money, less water less gas because you have received the hot water already

[@kerneldave]

So now after seeing this I will keep the economical button (eco button) on. Thanks for explaining.

[@kkg108]

do you use eco button when using central heating?

[@greenfeather50]

Thanks. My boiler was serviced yesterday and they must have turned preheat on. Boiler is in the bedroom so kept waking us up all night firing up. Couldn't for the life of me work out how to turn it off. Must bear "press and hold" in mind for any similar future situations.

[@rabbbie99]

Thanks I never knew what this eco button did . I was thinking that something was wrong with the anti frost function on my boiler causing it to come on at the wrong temperature intermittently. Sick of getting woken up through the night by my boiler firing up in the attic above my bed. Hopefully I'll have peaceful sleeps now.

Perfect, the exact explanation i was looking for , thanks

Excellent! Thank you very much. A very clear explanation. 😅

[@davidgarfoot3436]

i had a smart meter fitted noticed was using gas but nothing switched on then realised why now so switched it off worked out going save me about £10 a month now so i typed pre heat switch how to turn off and this came up cheers

[@pfvirus]

What if you have a water meter, and every time you want hot water, you wasting few litres/gallons of cold water before it become hot. Is that really an Eco solution?

[@djhatstand7312]

But then the preheat function will be using your gas and electricity numerous times a day to keep the water hot ready for when you turn the tap

[@sheilaaynsley9440]

@@djhatstand7312 I have a Comfort II programmer, in summer I set the times when I need hot water, like first thing on a morning. In winter when the heatings on I switch the water to Eco mode. I'm also on a water meter.

[@glenc3249]

Negligible mate. Over ten years, you'd be lucky it cost you the equivalent to a round of beers at the pub. You would just press it if you were going away on holiday; unless it's a winter holiday, leave it off and prevent your pipes freezing.

[@globeheating1684]

This function isn’t about storing domestic hot water like say a small hw tank. It keeps the water in the boiler hot that is used to heat the passing cold water through the boiler when a tap is opened . this function’s benefits is massively outweighed by its negatives. It reduces boiler life and uses more gas in most circumstances

[@winstinwin7650]

So are you saying eco is good or bad? I can’t decided what to set mine to???

[@miketait1640]

Likewise..nice clear explanation. Wondered what that green button was for.

[@YorkieKilla]

Should I still have my boiler on the timed setting while using eco mode? Is it wasting money by having it on the timer as well as the eco mode?

My Worcester combi boiler is taking a minute and a half to get hot. It’s a nightmare. Everything is turned to full heat too, I’m sick of washing up in cold water because I can’t keep waiting for the water to heat, plus I’m on a water meter :/

[@robdangerfield7129]

I have been turning this on. However, I am waiting a ridiculas amount of time for hot water. I say hot, I mean usually luke warm. So, I decided to switch the button off. Problem is, it keeps on coming on everyday. It seems to default to on.

[@vsgP7117]

Thanks for the Eco button! How about the White Key which should be off by turning to Off position whilst repressurising it? The video Inwatch says turn to On position facing to the Left position before pulling the key off downward from the boiler. I did so what it says turning it to On but what happens next the Arrow goes higher to no 2 when I have just set it on 1.5? So I turn the White key to Off!Please Explain, thank you very much for your Vlog.

[@brad_mcallister]

Holy shit that was interesting and useful

[@stephpowell7648]

What is the model/make of the boiler in the video

[@terrythurkle9118]

I hope you can help. Iv just moved into a house that has a greenstar 28cdi. There doesnt appear to be a thermostat anywhere! Not on the front of the boiler, not on any walls. All we have is radiators which we can individually turn up or down but when their off the boiler is still saying 56 degrees.

[@russellbardsley8583]

My combi isn't on eco & wastes loads of water before it runs hot ! All other boilers have had a filling loop which is easy to use,but the Worcester has the filling key ..

[@grapewater123]

What model is this ? Does it have a holiday mode feature?

[@castledene2000]

I have a Worcester Greenstar Eco boiler, after the boiler was service the radiators started to warm up even thought the room state was down to 12 degree. Worcester Tech stated this was due to the preheat and I was to press the eco button which I did, the digital display stated eco for 2 days the rads didn't warm tp my knowledge it may have done when I was either asleep or out, but now it has started again (Boiler only fires up for approx. 5 mins, then shuts down. Any ideas why? I can understand the preheat for hot water but why rads and anyway it shouldn't be on preheat.

[@michaeldunne9431]

Is your boiler installed in a garage or loft? It could be frost protection in the cold weather.

[@michaeldunne9431]

And not wanting to offend you, but are you sure it hasn't dropped below 12 degrees in your home? If you gave a standard thermostat you should hear a click as you turn it, that is the temperature it's reading. If you have a digital thermostat you should have a 'actual' temperature as well as a 'target' temperature

[@castledene2000]

I think it was a faulty room thermostat, which I have had changed. The temp in the house wasn't lower than 15 degrees. So far all seems OK. Thanks.

[@lawrenceogden2162]

good watch never knew that

[@EclecticBadger]

Oh the irony - that to turn something OFF you have to turn an LED button ON (I had to double-take the manual to work this one out too).

[@michaeldunne9431]

You are turning preheat function off, but economy mode on, hence the green light. On the newer models it will show on the digital display either 'preheat' or 'eco'

[@Reikiloz1]

Eclectic Badger in

[@vsgP7117]

Eclectic Badger that was what I thought I turned that green button to off. Now I watched another you tube on how to repressurise the boiler After bleeding the rediators; demonstrator said the White key must be on Off position whilst bleeding so it means after turning back the water button to Off position the White Key should be on On position, am I right?

[@EclecticBadger]

@@vsgP7117 for the 'internal filling loop' (the one that needs a key): Before using the key you would bleed the rads of air first. The existing pressure in the system will force the air out of the rad, resulting in an obvious pressure drop on the gauge. Next, close off all radiator bleed valves before re-pressurising as normal: Ie. insert the key, turn from closed (off) to open (on), then slowly open (turn on) the mains water supply valve letting water in until the gauge reads 1.0 bar. Once at the correct pressure, close (turn off) the supply valve, then turn the key from open (on) to close (off) and remove. If you over-pressurise, making sure the water supply valve is closed (turned off), and the inlet key is also closed (turned off/locked), bleed water from the nearest radiator to the boiler until the gauge falls to within the 1.0 to 1.5 bar range.

[@oldcargeezer]

My ECO won't stay off. lf l turn it off it comes back on the next time the boiler turns on, so you can turn "ECO" off in the evening and the next morning when the boiler comes on, it's back on ECO lt's actually quite annoying as we would like the instant hot water facility.

[@samrawlings2764]

Hi i have this boiler is the blue light meant to be in permanently as our other boilers only ones on when using the hot water ?

[@lillianflorence6056]

Yes blue light always on, always and green ,, eco light

[@Barney29508]

I have my 40cdi switched to eco. Should I be able to hear anything at all from my boiler? In the depths of night I hear the "hum". I'm a light sleeper! Once I hear the hum I can't get back to sleep. I check the boiler and although the eco button is green, something is obviously switching on and whirring away, perhaps a motor or a pump, I'm not sure. But if preheat is off by virtue of eco switched on, should it be totally silent?

[@Martindyna]

This may be the pump being run for about 5 seconds every 24 hours as an anti seizure measure, certainly older Worcesters used to do this.

[@tomwheat1853]

I dont mind the delay as i know its saving gas

[@HumberFlyer]

but don't forget it will use a lot more gas each time before any decent hot water comes out of the tap

[@SE09uk]

With DHW if you run the tap slow will the water be hotter that at fully open In other words is it safe to run a on tap mixer shower on a boiler like the 28i on out 28i if you ran the hot tap on low the water was a lot hotter that fully open

If you don't have to filling loop built into the boiler then you will have a external filling loop. If you have a combination boiler this will usually be on the pipe work below the boiler. If you have a system boiler it may be in your airing cupboard.

[@zenithnine]

did you get it working. I just been through this with mine and wasted a day before I realised what was going on. Think it only tries to resync the thermostat to the bolier in the first 20 seconds after the new working batteries are put in. If after that it hasn't found the signal then it gives up trying. I ended up taking thermostat off wall and up to the bathroom where boiler is, then i put the new batteries in , then i could watch the lights on the boiler. It finally found the signal and synced, then i could take it back to the hall and put on the wall again.
