GLEDHILL PULSACOIL 2000, PULSACOIL 111 OR PULSACOIL 3 AND PULSACOIL A CLASS REPAIRS
THE PULSACOIL 2000 IS A LARGE THERMAL STORE WHICH IS DESIGNED TO PROVIDE AN IMPROVED METHOD OF SUPPLYING MAINS PRESSURE HOT WATER , UTILLISING CHEAP RATE ELECTRICITY.
MAINS WATER IS PASSED THROUGH A PLATE HEAT EXCHANGER WHICH ALSO CARRIES THERMAL[HOT] WATER ALONG SIDE IT, A PUMP SPEED CONTROL BOARD TELLS THE PUMP HOW FAST TO PUMP THE HOT WATER AROUND THE PLATE HEAT EXCHANGER FROM THE STORE, DEPENDANT ON THE DEMAND ON THE FLOW OF HOT WATER REQUIRED AT THE TAP.
SOME OF THE MORE COMMON FAULTS FOUND ON A GLEDHILL PULSACOIL 2000 ARE:
1. FEED AND EXPANSION TANK EMPTY, GIVING LOW WATER CONTENT TO THE STORE, WHICH WILL EITHER DAMAGE THE UPPER IMMERSION HEATER, OR CAUSE THE OVERHEAT THERMOSTAT TO TRIP OUT. YOU MAY FIND THAT THE RCD/RCB ON YOUR MAIN FUSE BOARD HAS TRIPPED AS WELL. THE FEED AND EXPANSION TANK is NOT USUALLY FITTED WITH A MAINS SUPPLY TO AUTOMATICALLY TOP THE TANK AND THIS IS USUALLY DONE BY BUCKET !!! ALWAYS CHECK YOUR FEED AND EXPANSION TANK TO MAKE SURE THAT IT HAS WATER IN IT TO SUPPLY THE STORE.
2. FAULTY OR STICKING PUMP.
3. DHW PUMP SPEED BOARD IS FAULTY
4. DEFECTIVE DHW OR PHE SENSOR FAULTY. T1 [DHW] T2[ PHE RETURN SENSOR].
5. THE PUMP SPEED CONTROL PCB WILL SHOW FAULTS INDICATED BY FLASHING L.E.D LIGHTS.
6. LEAKING/ DRIPPING HEATER ELEMENTS, MOST COMMON TYPE ARE SKEL TYPE WHICH WERE ORIGINAL EQUIPMENT WHICH LEAK FROM THE THERMOSTAT HOUSING, AND USUALLY LIMESCALE BUILDUP ON THE INTERNAL SURFACE OF THE HEATER ELEMENT IS THE USUAL SUSPECTS [ IVE HAD SEVERAL IMMERSION HEATERS THAT HAVE FALLEN APART AS I HAVE TRIED TO REMOVE THEM !!!
THIS WILL CONTINUE TO LEAK ON TO THE ELECTRICS AND THEN TRIP OUT THE O/HEAT STAT AND SHUT THE STORE DOWN. [ AGAIN MAIN RCD/RCB MAY HAVE TRIPPED ON YOUR FUSE BOARD ].
THIS IS NOT THE TOTAL AMOUNT OF FAULTS THAT CAN BE REPAIRED BUT JUST A FEW MORE COMMON ONES I HAVE COME ACROSS OVER THE YEARS.

gledhill pulsacoil 2000 repairs; customer complained that they had no hot water pressure at the tap. mains pressure was good,but was in a very hard water area, plate heat exchanger was very scaled up and needed replacing. fitted an inline scale inhibitor and replaced plate heat exchanger. left in working order, with a very happy customer !.

pulsacoil 2000 repairs,customer complained of lack of hot water and fuse continually tripping out overnight, they had been reseting it every morning for 3 weeks with no hot water.found that the bottom immersion [ off peak] was leaking onto thermostat and every time the off peak electic kicked in it would trip the breaker on the fuse board.top immersion was defective due to feed and expansion was not loaded with water and had lost its water due to bottom immersion leaking and not able to replenish itself .i ended up replacing both immersions and adding fernox inhibitor to store, refilled system, tested. another happy customer with hot water.WITHAM,essex.
gledhill pulsacoil 2000 repairs, customer complained that they had very limited hot water. found that the off peak immersion was leaking and had tripped out the breaker on the fuse board. drained down and added sentinel x100 inhibitor and fitted new 3kw immersion heater, reset breaker, refilled and tested, left in working order. boston, lincolnshire.please note "tea cup "
gledhill pulsacoil 2000 feed and expansion tank.check the water level, it should be just in line with the ridge on the tankwhich is approximatley 8" from the bottom.this tank does have a cold water mains supply to it so it will top itself up if needed, many tanks need to be manually filled usually by a bucket.auto fill is ok as long as the ballvalve has not seized! a common problem for the pulsacoil 2000.
GLEDHILL PULSACOIL 111 REPAIRS : customer had complained that there was never enough hot water to have a full bath. found that off peak immersion heater had tripped out and tripped the breaker on the fuse board. customer did not know that there is a boost immersion available to give limited hot water. drained store down, added sentinel x100 to store , fitted new immersion and refilled and tested,left in good working order. note that this pulsacoil has no mains supply to the feed and expansion tank and so had to be refilled via a garden hose of the outside tap.SAFFRON WALDEN, ESSEX. THE SPIKE
pulsacoil 111 repair, limescale build up has affected the thermostat rod and arcing across the thermostat, making it run continuously and making the store water boil .replaced immersion and added inhibitor to store. BASIN APPROACH, E14.
probably the worst damage to a pump i have seen in over 27 yrs in the trade !!!!, caused by a leaking pump valve. as soon as the pulsacoil 3 was switched on it would trip the breaker on the fuse board, replaced leaking pump valves and pump. HARROW / STANMORE AREA.
