yes boiler now works ok. when the hot water is on its fairly quiet.when the central heating is on after about half an hour it does a lot of banging and rushing water sounds from the boiler then tales off and on. i have opened the by pass valve a touch more to see how it went seams about the...

could be, i seam to remember years ago before i did any work on the system that the valve was closed. if i do close it will that cause a problem.having tried to have a closer look it does look like it goes to the water mains ? (so a constant feed )also what if the valve is kept open ?

hi, i have a myson boiler approx 18 years old. has worked fine all this time, had a few spares thermocouples, thermostat 2 x controllers and 3 way motorized valve. i have just fitted a new 3 way valve (actuator only) and noticed a 15 mm dia copper pipe with a shut off valve. this pipe is...

yes just had a look at it. its a danfoss type hsa 3 it does click and makes a slight buzzing noise when i turn on the system. there is a metal lever type arm on the side this moves the plastic valve a quarter of a turn and then half a turn. it always returns to the original position . hope this...

is this the 3 way motorized valve this is the part what sends the hot water to the water heater tank or to the radiators it has 4 wires from it

hello, i have a open vented c/heat system its approx 18 years old but worked ok for this time. recently i bought a new controller (potterton e 2001 whatever) this as worked fine but just recently the boiler will work and heat both the hot water and cent heating without the controller asking for...

hi me again could i install smallish fans on the north side to blow air over tto the ridge etc

hi this condensation is only on the north facing roof ?

hi, still got abit of a prob in loft wit condensation. the loft is insulated with 50mm kingspan with a a 50mm air gap between that and the roof felt/tile for the ventilation. the insulation covers th roof section but comes approx half way done the roof were i created side walls again with...

hello, i have a myson boiler for central heating and hot water. it is an open vented system with emersion tank and 5 rads. the problem seams to be the rads get very hot to touch, they all have thermo valves fitted but still get very hot even when i turn the setting down ? the boiler does kick on...

i do think because the gap is now approx 60 mm it has made a difference,it does worry me that once i finish it off with the vapour barrier and tongue and groove the condensation will return. just have to suck it and see

the condensation prob i had in the loft has gone for now, i removed the kingspan from the roof and it compleatly dried out , when using the shower i have closed the door and opened the window. i have since put the kingspan back but incresed the airgap from 35 mm to approx 60 mm and taped up the...

the problem we talked about it (that the door we wanted would only fit that size because of the leaded glass in it ) knocking the plaster back is not a problem as we are getting rid of the artex finish and replastering any way , just wanted to know the correct way of going about it.

what i mean is the plaster on the inside. lets say the new door is 800 wide. the gap between the brickwork is 810 wide thats ok but the inside plaster to plaster is approx 800. the company installing the door say that the hinges on it wouldclash with the internal plaster (they are hinged on the...

next week i am having anew upvc front door fitted. the prob being the plaster (artex) needs to be cut back by 40 mm so the door will fit, it is a wood frame house so i will lose the insulation gap around the door. once i trim it back can i just skim over the brick is this ok or do i need to any...

cheers thanks 4 that. i think i will add polythene sheet between the t and g and the kingspan, the kingspan is a good fit between the rafters but warm air could be getting through(a few small gaps where i cut them and butt up to each other)

hi this condensation prob in loft, just riped the kingspan off i only got 30 mm air gap dont think this is enough ? shall i increase it to 70 mm and see how it goes ?

yes i got same problem but only on the north facing roof ?

hi still got it bad on north facing roof when using shower kept window open to extract the warm air, pretty cold last night and quite a lot of water drips etc. still thinking to make the air gap in the roof bigger say 70 mm (its about 30mm now)and install polythene sheeting between the kingspan...

hi me again no condensation in the loft near the eaves (this part not insulated roof kingspan) but some condensation in between the kingspan and roof felt. got approx 40 mm air gap should i increase this gap for better air flow ?
