OP what kind of heating do you have in the flat ?

HiYa southcoastrgi,

- see the pics he posted here

HiYa espresso,

- its a 'system' not a stand alone
- they run from 6-12kW
- wet rads flow rate supply of around 10 litres a min
- they have a 3 bar safety valve on the pressurised one
- and the one in his pic has a PRV overflow so its pressurised

Where did you get the 2kW "Aztec Gold" from ? they are only half the hight of a normal install and that looks full size. I've downed the pics and can see no reference to kW size but all the 'system' boilers all need a service supply of 100A / phase.

Wrong again Richie!

The boiler above the Megaflo is a Trianco Aztec gold system boiler rated at 2kW.

As previously stated, it is obvious from the pictures that the cables are not capable of supplying more than 3kW, definitely NOT 6-12kW!

Details of the Trianco Aztec gold 2kW can be found here.

I don't see how your incorrect guesswork can help the OP, who should be using the programmer to control the boiler and not use the "Hot Water" switch which is for the back up immersion heater.

thanx Richie i have seen the pics

however that is a single channel prog so either the OP has electric heating & the boiler is just used for the cylinder or is as below, however there are other things that don't add up, there is only one immersion wired so it's not true econ 7 if at all, if the programmer time is correct then the immersion isn't wired to econ 7 or the red light wouldn't be on at that time of day.

so until the OP comes back with more info, looking at those pics i would suggest the boiler is bigger than 2kw as it appears to heat the rads, the megaflow is a direct model (not indirect) & is only heated by the bottom immersion (as i can't see a zone valve), only wired for normal mains supply not econ 7 as the bottom immersion would normally be for econ7 & the top one (not wired) would be for top up connected to the switch in the pics, if this is correct then it's a very expensive set up to run

Hi guys,

Thanks for all of the replies. I had a read but half of that went over my head. What do you need to know from me?

The radiators are not electric, they're driven by that boiler (Which is electric). I triggered the timer panel the other day and the radiators got hot.

So from what I can understand from the conversation, the top boiler is for heating only and I have to use the immersion for hot water?

Also my electricity meter says "Economy 10" on top of it.

- I know you said that already - I asked you how you know its the The boiler above the Megaflo is a Trianco Aztec gold
- so how do you know, guesswork can help the OP

it is obvious from the pictures that the cables are not capable of supplying more than 3kW

- I don't see how your incorrect guesswork can help the OP

it is obvious from the pictures that the cables are not capable

- I said they run from 6-12kW, I did not say it was a 12kW
- unless the flat was owned by Richard Branson its liable to be 6-11Kw
- a two bedded + water will be fine on a 9kW
- a 9kW will be a cable size 6 and an 11kW will need a size 10

using the programmer to control the boiler

- I agree with

Most of your other stuff is adversarial, proven wrong and there's no need for it is there ?. You are turning into a grumpy old sod espresso!

OwDo southcoastrgi,

thought the coffee man had disappeared off the face of the earth

- we can but wish, he used to be ok, now he's just cobby and he gives my keyboard toothache

not true econ 7 if at al

- agreed, but still a cheap rate night / day variable

bigger than 2kw

- agreed, but E7 E10/12 or any variable s/he will still have separately wired standard 3 kW immersion element for the summer, it looks to be a standard E7 / E10 wired cylinder with the usual 'boost' safety.

EDIT - as I took the bairns home s/he posted so s/he is on E10, I assume the wet rads are off, and its a timed or otherwise 'boost' element for summer use.

The one at the bottom marked 'water' runs your hot-radiator~water and the one at the top marked 'boiler' runs your hot~tap~water.

E7 means 7 hours of cheap leccy and 17 hours of expensive leccy

E10 means 10 hours of cheap leccy and 14 hours of expensive, on and off times vary slightly by provider but are something like midnight to 5am, 1pm to 4pm and 8pm to 10pm.

Hi guys,

Just moved into a new flat (Renting) and i've discovered that im on Economy 7, with what appears to be an immersion heater.

I've taken pictures of the heating system I have, so that its easier to understand what I'm talking about.

icloud.com/photostream/#A359UlCqT5u1q

My estate agents and landlords are terrible and its easier to ask on here than try to get them to explain what the best way to use all this is.

If i switch on the "Hot Water" switch i assume the immersion comes on as I am able to use hot water, leaving it off means that the hot water runs out after a day/day and a half and doesn't come back, so that must be the immersion. No idea if i'm supposed to leave the switch on all of the time or just a few hours each day

I'm assuming the boiler above it is for the heating only? I changed the programmer panel to "On" and the radiators came on.

Also the black opening pictured is dripping and it says that I need to reduce the air gap in the tank if that happens, the instructions are also pictured but i've no idea which each of the taps/valves mentioned are! If you think you can help, perhaps I can PM you a link to the photos.

Any help would be greatly appreciated.

It appears the programmer only operates the boiler, which you say provides space heating only.

I would suggest turning off the boiler switch until you need it. Leave the programmer switch on - it only uses a tiny amount of electricity and may have a battery back up which won't last long if the power supply is turned off.

A shame you don't appear to have a timer on the immersion heater which is operated by the hot water switch. This only needs to be on a couple of hours a day at most (unless you use a lot of hot water), preferably during the cheap rate period of supply.

As you are supplied on E10, you need to understand how this works exactly (different suppliers have different systems). Perhaps the immersion heater is on a low rate only circuit?

The photographs identify the boiler, it is not guesswork.

It is obvious from your posts that you are guessing and have not helped the OP at all.

- I said they run from 6-12kW, I did not say it was a 12kW

- a 9kW will be a cable size 6 and an 11kW will need a size 10

The Aztec Gold boiler is not available rated at 9kW and there is no 6mm cable in the pictures!

Wrong again Richie but you are either simply showing your total ignorance or just trolling again.

The "Hot Water" switch controls the Megaflo for the hot water supply.

The "Boiler" switch along with the programmer control the heating.

MattCheetham

Well i've turned off the "Boiler" switch for now as you're right. I won't be needing the radiators in these temperatures!

Strangely, turning off the boiler switch and leaving the programmer switch on results in a flashing battery light on the programmer display. Presumably its power comes via the boiler which is strange.

Yeah its a shame the immersion doesn't have a timer as that means I now have to remember to turn it on and off at the right times. That could take some getting used to.

I'm going to give the electricity company a call back tomorrow and ask about the times for economy 10.
