megaflo electric boiler problem.

[xs11ax]

Hi all

I was called in by a friend to take a look at his megaflo electric boiler which is only used for hot tap water. No radiators. He has been in the property for a couple of months now and has had no hot water since.

He had it looked at by a boiler engineer who told him it was a plumbers job and not his and then had it looked at by a plumber.

Plumber told him the boiler needs flushing and said it has no pressure gauge so needs a pressure gauge fitting on. Quoted him £200 plus parts.

I have had a look at it and checked the cables to see if their is a current going thru into the boiler which there is. the timer seems to be ok as well although i might be doing something wrong as i have no experience of electric boilers.

I thought the plumbers advice sounded a bit daft as there are no radiators used from this boiler just tap water so cant understand why it needs a flush. Also i have not seen a pressure gauge on any electric boilers i have looked at on the net.

So can anyone tell me if the plumber was right and if not what could the problem be.

Cheers all.

I think the plumber is talking out of his proverbial

There is no pressure gauge needed for a direct Megaflo as you say. They are also made out of high grade s/steel so should not scale up either.

If it is a really old one it will have a sacrificial anode fitted to help prevent scale as well. This may need replacing from time to time.

To me the most obvious thing causing this is the immersion element has gone, or the thermostat in it, especially if you have proved there is current/voltage going to it.

Why do you need more ideas? I would think Dave's reply is more than adequate.

well i have been scanning the forum and the internet in general and come across something about a safety cut off switch so i was thinking if there is anything else that we might have missed.

There is a little red button on the immersion heater that acts as an overheat cut out.

It will be obvious if this has popped out. If it has popped out it will have done so for a reason.

I forgot about this

i have been trying to find a manual on the net so i can locate the button but cant find a manual. can anyone tell me where the button is?

On mine (indirect) it is behind the cover for the thermostat on the cylinder there is a red reset button. Remember there is voltage behind the cover
