BAXI BERMUDA CENTRAL HEATING

don't do a powerflush, they're a bluff at best with no quarrantee, you've got a physical blockage and the first place to look is the 'dumb' valve, its a little one way valve that looks like a brass couplling, its reason is to stop circulation in the summer to the rads but can often jam, second place to look is the pump valves they might not fully open,
if it was the heat exchanger the water would not work either so its not that,
powerflush work is satans work, get thee behind me,

 

Definitely a circulation problem. The pump could be running slow. I had one from new like that once. Ever thought of replacing it. They are really yesterdays technology and make noises in your living room.

 

Tom you cant powerflush a gravity system, Ill let you figure out why.

 

ever heard of blanks dave? or are you thinking primatic,, even a pumped system you need to blank the tank,,,but wait a minute I don't do conman work how would i know anyway,

 

Fire them all the time

 

Amazing how many people still have a Baxi Bermuda boiler, I had one here when I got this house,it been in use for 25 years or so, so first job I did was to rip it out & fitted a Vaillant ecoTEC Plus 824 combi boiler.

Scrap it is my advice.

 

I have a Baxi bermuda in my first floor maisionette. I heard that they may have to replaced ..

 

thats because the old boilers where british made and extremely good quality boilers but the gov't, not the boiler makers decided that they were too reliable and not what this nation needed as they were not helping the unemployment figures, so they made new laws to create jobs in the boiler manufature and spares 'n repairs, like maggie thath invented globel warming to close all the mines, the gov't of the day invented inviro friendly green condensating boilers that need massive amounts of service ,repairs and have took the boiler sparea industry from a corner shop in the 1980's to a hypermarket today, most made in china and as reliable as a drug addict,
if you've got a back boiler keep it as long as you can,

 

Tom is prattling tripe as usual. He uses lead pipe you know. The old cast iron boilers are hopelessly inefficient. They are about 55%. Get a new condensing boiler like the Intergas, with few moving parts, and your bills will drop 35-40%. Getting open flued boilers out of the house is a great thing - they are dangerous. This cast-iron lump should be ditched ASAP.

 

Eeee Walt you know I am a straight shooter,where's the old sludge bucket Walt gone who loved the proper tripe, anyrode you don't have to take my word I can produce facts not percentergages,
how big is the boiler spares market today,,,,,answer massive
how big was it in the 1980's......perhaps 10 shops nationaly kerrr ching,

open flued boilers provide a constant flow of air from the outside lower to the outside higher, there's no better way of ventalating a property, houses built post war with chimneys will stay with us till world war 3, new builds with wrap round insuation and no ventialtion will fall down of their own accord inside my lifetime and that's a good thing, because they're are a breeding ground for vermin,lice,mould and everything that humans need to keep away from,

 

Mr Plum, there are far more boilers around than there were in 1980. There are also more cars and more car spare dealers as well.

My God Tom is on about using a dangerous boiler instead of an extraction fan. My God. If the flue blocks the occupants can die - stone dead.

 

who mentioned ex tractor fan? no I sir, but that's a very fair point about car spares, they too noticed a market for adding working parts with self time obsoetetion as standard, any old anglia or cortina could be fettled by your average diy person but now you need a fault diagnostic machine at £sssssssss,
well spotted Walt,

 

Mr Plum, old cars polluted like hell and were slowly killing us. Did you know that? tsk, tsk.

 

ALL cars are pollutive now there's more of them faster and heavier, anyone in the wrong side of a rangerover doing 100mph is spared the slow death of pollution's

 

No mate it won't be a single pipe system, well I'm 99% sure it won't, have a look for that dumb valve, usually close to the boiler in the boxing in against the chimney breast is a good place to start,

 

If it is a one-pipe system lower the pump's speed. If the speed is too fast the flow runs right past the rads and only circulates in the one pipe. If it is still on the lowest speed throttle down one of the pump isolating valves.

 

Kyote, on the CH setting your boiler fires up, gets real hot, and then shuts down and starts 'cycling'?

And you have access to the 'flow' pipe from the boiler, which also gets hot? And this pipe goes to the pump - how hot does that get, on either side? And then to the NRV? And then what?

Do you also have access to the CH return pipe to the boiler? How does that feel?

This new pump - is it fitted the right way around...?!
