Pulsacoil 2000 - leak

Hi

We noticed a small pool of water at the base of our Pulsacoil 2000 yesterday. I couldn't trace the cause of the leak but did notice various signs of previous leaks. None seemed fresh so we dried out the cupboard as best we could to see. There were no further signs of leaks throughout the day, however this morning the puddle was back. Again there's no signs of any leak from any of the outlets, it does seem to be coming from the base of the tank. I also noticed that the circuit board LED indicates that the pumped return thermistor has failed, and we did find the header tank extremely low on water around a month ago.

Does this sound as if the tank has failed?

I understand that this is a terminal fault. If so, would you recommend replacing with the ETS 160 or a new Pulsacoil?

Thanks

I would try leak sealer (from fernox)firs before i would go for an new Boiler, if this works, well spend £25 as a new Pulsacoil for £1200 +VAT +fitting, and of course new sensors as you mentioned.

Thanks for the reply.

I've spoken with a local plumber who has experience with other flats in our block and he said that it wouldn't be possible to access the leak to fix, which is what I also felt after looking over the boiler. Do you have any advise as to how to get to it?

He also confirmed my suspicion that it is likely to have to be replaced.

What does anyone recommend as a better replacement?

The capacity of our current system is 140L I think.

You cannot repair the leak as the cylinders sits behind foam and to access the leaking area you will have to take the entire system apart. This is next to impossible. Your best option is the Pulsacoil BP150.
