How to turn the water temp down

[MAV84]

hello everyone, my name is mav, i've stumbled upon this forum in the hope to get some help,
My problem is that the water has always been really hot at the flat, i was wondering if anyone knows how to turn the temp down on this type of cylinder boiler, i dont know what its called but have found a pic that pretty much looks like my one in the link below,

you should have a cylinder stat on the cylinder, or near the cylinder. set it to about 55-60 degrees

Hi mate thanks, i've changed the link as i inserted the wrong one, if you could look at the link Hot water cylinder image by kkc35348 on Photobucket

mine is pretty much the same with the a wire coming out the bottom and one out the top, where exactly am i looking to turn the down? there is nothing near the cylinder to turn it down so i assume its on the cylinder somewhere, i think its quite old, it has a mint green cover on it,sorry i've not a clue, any info would be much appreciated, cheers

is it linked up with your heating system ? or heated up by immersion heaters ? e.g do you need the heating on for hot water or do you just flick a switch ? type cylinder stat into google see if you see anything familiar or you can change the temp on the immersion heaters which is the thing with the wire coming out of it to the switched spur.

stored water should be set to 60-65, any lower can potentially cause a legionalla problem

hi there, the heating in the flat is run on electric, it's just for the water, i googled cylinder stat and i dont recognise anything barring this pic, my boiler is the exact same colour if this helps? its not the best of pics but cant find any others..thanks

The thermostat is inside the cover of the immersion heaters. It should be set to around 60º

If you think you can do this yourself this is how it is done but if you are not sure, get someone in to do it for you.
Turn off the power to the heaters. Remove the small nut holding the cover in place and remove cover.
Inside looks like this

The thermostat is the blue part on this picture (yours may be a different colour but will look similar) and the adjustment is the white bit in the middle of it.
Use a small screwdriver to set the thermostat to 55 - 60º.
Replace cover and secure with small nut.
Turn the power back on.

go to the other link i posted there and you'll find how to do it there, and set it to 60-65 degrees as kirkgas said

cheers guys for all your help, mine has one top and the bottom of the cylinder, are they both for temp control? also do i have to turn anything off or drain before adjusting the temp? thanks guys

edit-sorry i just see that i have to turn off the power!

you only need to turn off electrical supply, you'll find some info on that site about the 2 immersion heaters

 

[kirkgas]

if you have 2 immersors you will find the lower one is on late at night powered by off peak(lower tarriff) electricity to heat the whole tank, the higher one is for boosting hot water during the day if you have used up what was in the tank, this uses peak tarriff so should be used as little as possible as it is a lot more expensive, you should only be using one or the other at a time

thanks for your help, how do you determine which one is used more?

Also is it the top one that has to be adjusted for the temperture, or both?

edit- i just see on that diagram that there is just one temp control even if there is 2 elements! is it the top one that has the temp control?

cheers

Thanks for your help and for the diagram, its very helpfull.

i know this is off topic but i have a power shower that wont power up, it has a pull cord next to it to give it power which is fused, when i pull the cord it does turn on, but when i actually go to turn the power shower on, there is no lights or anything or the actual power shower unit it self ? is that any basic checks that i can look at? thanks

If it doesnt work at that its a job for an electrician.

Do not set your immersion heaters under 60 degrees or it can cause legionella. If you want to reduce the temperature at the taps you need a thermostatic mixing valve under the sink.

Hello there thanks, so if the temp is already set at 60 degrees does that mean that I need a mixing valve under the sink? Will I need a mixing valve on all taps if that was the case? But if the temp is high, should it sort out the by turning it down to 60 degees? Thanks for your help

 

[GQuigley67]

the temp is more likely 70 if you find it very hot, have you checked it yet ? if so reduce it to 60 and if still too hot then mixer valves are your best bet but they are not ideal imho they are big and hard to hide, they are good if they are hidden away but not if its behind your basin for instance

if set up properly the bottom one will be on every night on off peak, with the top one only coming on when you press the boost button, they should both be set to 60-65 if the hot water is too hot in the morning it must be the bottom one that is too hot, if it is when the boost has been used then it must be the top one

Hi, it says in the diagram Immersion heaters | DIY Tips, Projects & Advice UK | lets-do-diy.com to put the day time to 50 -55 degrees if i have 2 elements which i do?

 

[MAV84]

Hi there, I've just checked the top element and it was on 85 degrees!! The bottom element was on just over 55 degrees! I've now adjusted the top element to 60 degrees, it still felt quite hot but I'm assuming that temp won't adjust instantly?? Thanks for your help on this everyone

 

[GQuigley67]

85 degrees ? must of been scalding hot.

the temperature will cool eventually, changing the setting on the immersion heater just means once the water reaches 60 degrees the heating element will switch off, and when the water drops below 60 degrees it will switch back on and so on.
