draining a pulsacoil 2000
Hi Mike,
Many thanks for your very helpful and valuable advice on this forum.
Recently I noticed a slow leak from the bottom immersion heater on my Pulsacoil 2000, so this weekend I changed it.
The real problem I had seemed to be just how long it took to drain the tank. In over 1hr it still hadn’t finished and in my frustration I finished taking out the immersion only to have the very hot last 5 – 10 litres rush out everywhere and make a nice mess!
I also noticed that the pipe in the header tank was quite corroded and it makes me worry that the system must be getting quite furred up. In replacing everything I did add some Sentenel 100x and at the same time installed a sight glass so I can now monitor the level of the header tank more easily.
My question is, if I need to drain the tank again, do you have any advice to speed up the process? I did only use the bottom drain and not the drain from the heat exchanger. Could I use a drill pump or something like that to help draw out the water from the drain? Is there anything I can do it make draining the tank a bit easier in the future?
Many thanks for your advice,
Rich

2 drain off = 2 hoses.
That's what I do.
Towel over the pump though.

Re: draining a pulsacoil 2000
Hi Mike,
Ah! Hadn't thought to drain off at both points. Thanks - great tip.
The immersion change solved the significant leak, but since the area has now completely dried, I now notice that there is a very small amount of water that appears to be seeping out from where the bottom pipe emerges from the store (around the rubber grommit). Can that be repaired? If what do you recommend I should do to cure it and it it can't be fixed....put up with it?
Many thanks,
Richard

Re: draining a pulsacoil 2000
Hi Mike,
Any options open to us? Can these types of leaks be soldered or repaired in anyway or....
once the leak gets worse do we have no option but to replace? It seems to just be the tinyest leak.
This unit is controlled by a Nobo Orion 512, which I think you have suggested in the past is not ideal. What would you estimate the cost for a replacement of the whole shooting match? Is it a Pulsacoil BP (athough loathed to use the same make of unit that has lasted just 7 years!).
Many thanks,
Richard

Re: draining a pulsacoil 2000
You could try a leak sealer.
Mixed reports / views.
What is the unit standing on?
Combi boilers anything over 7 years is a bonus!
Pulsacoil BP unit would go in quite easy.
Albion Mains flow would too, but more money.
The BP unit would be the one really.
You could open it up to find the leak, but it may be higher up and seeping down.
New unit I think!

Re: draining a pulsacoil 2000
Hi Mike,
It's standing on a plywood base, ground floor flat.
Do I take it that opening up the unit is a big job? I have the skills to remove and replace the rivets, but is it a major job to take a look? Just seems worth investigating before shelling out for a new unit! Can you estimate the cost I should expect for fitting a new BP?
Cheers,
Richard

Re: draining a pulsacoil 2000
The unit is full of pumped in foam.
You are peeing in the wind!
Chances are the plinth is not taking the weight.
Quarter of a ton (at least) when full !
I always put them on 6 x 2" Joists with 20 mm ply.
And I mean plenty of joists.
The added height is handy ref the pipe work underneath.
Look on here for prices, the BP 150 is the common one.

Re: draining a pulsacoil 2000
I have a rather inevitable feel about all of this though :-(
Oh, and lastly - any thoughts about a 'proper' controller ? - you previously mentioned doubts about the Nobo Orion 512, which controls this pulsacoil and the electric rads in the flat.
many thanks again!

Re: draining a pulsacoil 2000
The Horztman E 7 timer is good.
If you have only 1 consumer unit and the time for E7 has to be set.
Or if you have 2 consumer units;
1 for E7
1 for peak.
Then I would fit a 20 amp DP switch for the off peak.
And another 20 amp DP switch after which a timer with 30,60 or 120 minute selections.

Electronic 7 Timer
I would recommend an electronic timer such as Horstmann. We have installed hundreds of these and not had any call backs compared to other ones. You can buy them on-line via this link: Gledhill Pulsacoil 2000 Spares
Re: draining a pulsacoil 2000
Hi Mike!
As you can see from the date of our earlier 'conversation' we've had a good run without any problems :-) However (!) a new tenant in the flat coincides with new problems....
It seems the thermostat on the normal immersion has tripped and after a day or so of being reset has tripped again. I've had a look and it does not seem as though the immersion has gone (no evidence of water leaking) and an electrical continuity check of the immersion heater element does not indicate it has failed either. Would you recommend changing the thermostat as a first course of action? They have tried the booster immersion, but from what I gather it had tripped too, which makes me think something else is going on (unless it is a coincidence and the booster thermostat has gone too? And I don't really believe in coincidences!!! :-).
Your advice would be greatly appreciated.
Many thanks,
Richard

Re: draining a pulsacoil 2000
I would go for a set ( 2 ) of new thermostats, as long as the immersion are tested ok, No big fuss. 5 minutes jobrichardhealey wrote:Hi Mike!
