PCB in question has marked on it EP1L0G02V10 and the smaller general board is marked up as EP300PW02V13 with the usual rectifier bridge on board. If it was just a resistor or separate component then one would expect a complete failure of the settings not just the very last one on only hot water.

My Potterton EP2 central heating time switch has come up with a classic problem now. CH settings fine and all work ok but the HW setting for ON/Off 3 will not allow me to go past 3.30 pm off time? Originally set at 4.20 pm and after a few years use wanted to change it to 3.30 pm but once set...

Thanks chaps for all your help in SDS Hammer Drills. Will go for the Titan for the big heavy stuff and have used my new Makita for the small hammering. Tried the Makita on my garage concrete floor and the bit went through in 30 secs compared with my normal percussion drill which went through in...

Hi Blub Have gone with the Makita HR218FT from Axminster Tools as they put in some drill bits and the FT model comes with the quick change chuck. Some companies sell £40 cheaper for the non FT model but then I would have to purchase the 3 jaw chuck separately plus some SDS drills to play with...

Thanks Blup Have not bought a new Makita power tool for over 20 years so did not know if their quality has gone down hill since they are no longer made in Japan to my knowledge. Most tools I have will last my lifetime (3 Makita power tools) but have seen some real rubbish being sold form China...

Will be doing some DIY work in the house removing floor tiles and also putting in some new cables in the kitchen which will need to be chiselled out. Also cleaning cement of patio slabs for re cementing outside. My question is should I go for a SDS plus hammer drill like the Bosch GBH3-28DFR or...

Thanks sparkymarka Will also have a look at the Premier 24 kit panel you have suggested. Think the metal box panel might be best instead of plastic. Just out of interest is anything from Texecom made in the EU or does everything come from that lovely place across the sea China? FlyingBrick

Thanks sparkymarka Anybody with thoughts on other control panels to look at in the middle market for home use. Happy to pay a bit extra than the cheaper bottom end control panels put into large housing estates. Looking for a reliable unit that will match the old XM6 but with the possibility of...

I installed a Optima XM6 control panel back in 1993 and put in Texecom Reflex Quad PIR units around the ground floor and garage which has run over the years without any problems apart from the usual battery replacement for the unit and the bell housing outside on the wall of the house. This unit...

Have been looking at the Neff B57VS4NOB oven and the Neff C17MS32NOB combination microwave for a customer. She went to the John Lewis website to look at the reviews and Mumsnet and they came back with terrible reviews about the touch screen and software problems. Nearly all the JL users had...

Microwave part of the appliance blew the 8.0 amp fuse inside and checked out the HT cap which was leaking badly, this in turn had cooked the HT transformer so when only half the mains voltage was applied with a variac it started to cook nicely at 10.0amps checking the HT voltage with a HT probe...

Thanks everybody Have been looking hard on the internet to locate a flow meter that does not cost the earth and can be used up to 80* centigrade for hot water. Also wanted the flow meter to set up my soft water system a Permutit timetronic 307 using tablet salt for regen as it does not have a...

Hi Gaswizard It was the heating engineer that put in the new boiler and left a seized isolation valve round the back of the 140 litre copper tank that had been used as a bypass valve. Still waiting for a certificate from the engineer that put the system in on the 21st December last year.

Thanks Bernard Could not believe the price for these mechanical devices, ok in industry but for a domestic CH system at home ouch. Just wanted to get some idea of flow rates in my system for setting up with a new boiler and pump. Would have liked to install one to keep tabs on flow rates but...

Have been looking for a flow meter that can be connected to an open vented boiler to measure the flow rates. There seems to be not much in the domestic market. Looked at the expensive RS spares website and for a hydraulic flow meter 10-100 l/min they were priced at £447.00 each? Could any...

Thanks D-Hailsham Next week will take off the TRV heads to make sure nothing is pressing down on the valve spindles. Have 14 rads to set up as the original bypass valve was seized and not changed. There is now a Danfoss AVDO ABV installed in the bypass pipe as the engineer had not replaced this...

Apologies for asking the question. But having had a gas safe engineer install the boiler and not balance up the system or set the bypass valve I was trying to understand how it all works. My thoughts were that if the thermostatic valves were set at a position lower than full on then the valve...

Thanks Agile info the info on hot water priority. Have now realised why the plumber did not take out the faulty bypass valve. It was positioned directly behind the insulated copper tank in the airing cupboard with a gap of only 7inches to the wall. Also the bypass 15mm pipe was sitting in...

Having had a new boiler installed and looked up the information on balancing the radiators in the house could somebody explain to a beginner why you balance them up with all thermostatic valves on max? i.e. My Westherm on position 5. I understand the balancing of the system for the required...

Thanks Tony for the information. Appreciated. Went into the FAQs section for balancing rads and that gave a 12 C differential that I used. As in my previous email I have not closed the manual bypass yet as there is a weep at the spindle end and the slightest movement to turn it around starts...
