thank you all very much indeed for very helpful advice. the area is about 65 sq m, divided into two aproximately equal areas on either side of an arch. plasterboarding would have been a good idea if not for the original plaster coving which is quite wide. since i understand now that...

We have removed woodchip paper from a lath&plaster ceiling with the intention of skimming over it. Now it appears that there is another layer of thin paper over the lath&plaster, which is very adherent and difficult to get off. I guess it is some form of backing paper. Could we apply a coat of...

dear AlanE and Onetap, many thanks for showing interest in my problem. the pump receives its power via a time-delay switch (to keep the circulator going for a period after the burner has gone off). when the pump had turned itself off after a normal start, the switch was still relaying...

I have a grundfus UPE 40 - 80 F 250 circulator for the central heating. it comes on fine but turns itself off for no apparent reason. ? overheating does any one know if it possible to repair them? many thanks

currently i have a Grundfos UPE 40-80F 250 circulator pumping my central heating system and also the heating coil in the cylinder. recently both heating and hot water are not quite good and i have now noticed that the pump is not always coming on (it has an led indicator showing the level) when...

many thanks again, bigburner yes we do have a rather large gas meter. the boiler gives me hotwater as well and there are two tanks in the loft. we bought the house recently and i am on a steep learning curve as far as these matters are concrned. thanks again vsr

yes i was thinking of economy of running, but am worries that the outlay will be large and payback time will be very long. i am sorry that i do not know what any of 'DHW', 'Vented cylinder' or 'U16 meter' are :(

dear bigburner, you have been most helpful. am i correct in thinking that i could do exactly as you suggested in terms of zoning/control (actually get a qualified person to do) while keeping the existing boiler ? the exisitng pump is a Grundfos UPE 40-80 F 250. many thanks VSR

unfortunately the system is not zoned. however, it would lend to have four zones, one of each floor. what would be the best way of zoning? a separate pump for each floor, with a multi channel control or a single pump (as it is now) with a motorised valve for each zone? the feed and return system...

sorry, the symptom is that several radiators remain cold.

dear fluffster and paulbarker, many thanks. it is a large house on four floors with around 35 radiators. how would the type of house effect the choice of boiler, would you please say? my existing boiler was only installed 5 years ago and had been serviced regularly. it is quite possible that...

many thanks indeed for everything you said, paul barker. i am sorry, but i did not understand the reason for cutting out a couple of feet of pipe and renewing it. also how would one knoe if infact there are blockages within the heat exchanger?

i currently have a hamworthy purewel 60kw boiler in working condition. recently some one suggested that i would be better off replacing it with a more effecient one. any one has any ideas about which model would do best instead and its cost? many thanks. vsr

i intend to use sentinel X800 to desludge my central heating system. will there be a problem if i left the chemical in for a whole week? my boiler has a cast iron heat exchanger and the pipework is old copper. many thanks vsr

dear all, in my new home, hot water taps appear to come off a circuit through which hot water from the storage cylinder is continuously circulated. this has the advantage that even with the cylinder in the basement, a tap in the second floor gives hot water without a lot of cold water first...
