If you have a zone thermostat check to see its up, and if you do have one and it is up your downstairs valve actuator (auto valve) may be faulty. (thats if you have any)

Hellrazer

You sure theres no pump?I dont know how can it be gravity fed unless your boiler is upstairs?

Id the same problem and it turned out the fuse in the pumps plug was gone.Replaced it and it worked straight away.

Maybe the rads need bleeding upstairs, its sumer anyway, its air-conditioning your supposed to be needing not heat, although with todays weather, i'm afraid the opposite is true.

Sparky...its an older hose so i dont have zone heating (would be nice tho!)

Hellrazer-- to be honest dude i dont have a clue...i dont recall ever seeing a pump. the gas fired unit is in the kitchen....so perhaps its part of that unit...

tried that boss...need it cos we have an 8 week old nipper and i dont want the little tyke freezing his wotzits off!

Sparky

did you blead the rads from the boiler onwards because there could be a gap of air trapped between your rads. Other than doing that there needs to be a pump somewhere and if so the fuse in the spur outlet or plugtop may be blown.

Adam

Probably an airlock, unfortunately i'm really no expert on how to remedy such a problem, or even establish if it is in fact the problem!

sparky i will check around and see if i can find a pump...i rekon it could be a fecken air blockage...

It looks as if you may have to call de plumber, watch them carefully if you do, they will try to rip you off so be careful.

Tbh, i would think it would be in the boiler, but ive seen some installations where a pump is used as a shunt to boost the pressure if it has to go far.

Is your boiler a poterton.

Sorry to get back to you so late.

ther eis buger all in the hot press other then the tank and the usual valves...and i do have the 2 cisterns in the attic (ie the uaual big cistern and a much smaller heating system one)

Sparky

can you get a model no. like proforma 24, 28 etc.

Fallschirmjager

Sparky its a netaheat profile -- no numbers its about 15 years old...

Sparky

Tbh ill have to assume that your boiler circulating pump is working if there is heat upstairs, your most obhious problem has to be a packet of air in your system downstairs, taking into account that the rad valves are open i think you should get a bucket and your vent key and blead the rads till your satisfied that there is no air, in my heating system i found air trapped after letting out at least 3 cups of water from one rad, do all the rads and failing that, if your rads are old there may be a grime blockage from age of the radiator.

thanks Boss...i owe you one....having read a lot on the web (god bless google) and the directions here from yuor good self -- i will give it a go...

thanks again...

Sparky

Sure no problem, Anytime.

seanogal

The problem isn't sludge in rads.If it were, only the bottom of the rads would be cold.The pump should be close to the boiler.I don't think an air blockage would block all the heat in the rads altogether.

Victor

Did someone turn off a valve?

Don't keep babies "hot", if anything a little cool.

Kernel

Someone in DIY / Gardening is guaranteed to solve this. They're a handy bunch in there.

deecom

sounds like the pump to me, same thing hapened, the thermostat had stop working, (never turning on) Should this not be in diy btw. Good luck with it, anyway its summer dont you know!

Fallschirmjager

Gentlemen,

as it happens you are all right to one degree or other....

i found the pump ( it was above the fecken potterton -- ahem in a big box -- which i might add was very vell hidden... )

i did what Sparky and the odd guy on google recommended -- give it a fecen good thump...twiddle the unual knows on the maching that go ping etc and BINGO..the rads are hotter then my embarrassment

Deecom..you got it it is summer -- isnt it ?? not in my gaff..had to tusk me trousers into me socks in case i lost me equipment!

Victor ...no chance the little tyke could be hot....

seanogal..u were right about the rads but i was concerned it was that cos the last guy who serviced pumped some crap into the system so i was afraid it was something to do with sludge but fortunately not.


well -- my thanks to you all -- saved me a packet there...i expect the pump will pack in but at least i now know where the little puppy is!

GENTLEMEN I SAULTE U !!!

if ther eis an admin here..u can close this thread dude...thanks
