Did you turn the power off to the boiler? If you did then I know whats happened. I would say that one of the seals on the plate Heat exchanger is leaking and it will be the hot water outlet o ring on that heat exchanger. Your boiler has a pre heat for hot water, which means the...

The most likely cause of a HF code is a problem with the detection electrode and or the detection lead. 'HF.' is another code that can occur. The DOT is significant. 'HF.' means that a flame has been sensed when the gas valve is closed which means you may have a fualty gas valve that is...

Tis the time of year for frozen condense pipes. If F2 is a flame failure code, then this could be the problem. Regards

Dont be concerned about the Logic boiler range. They are proving to be very reliable. I have been fitting mostly the combis over the last year or so and my customers are very happy with them. The Logic system+ has a 5 year warranty. There is a lot of negativity surrounding the older Icos...

Go direct to Vaillant. They will give you a difinitive answer on the availability on parts. They may even offer a fixed price repair. Sine 18's are getting on in years. They are or were very good boilers IMO. Regards

If your Isar shows a 'd' or 't' for most of the time then the boiler thinks it has a demand for hot water. The reason for this is that Isars dont look for a flow of water to switch the boiler on for hot water it looks for a drop in temperature. You are probably aware that you have a pre heat...

Thats incorrect. The gas valves for these boilers are 'FACTORY SET' and dont need and should never be adjusted. There should be a DC supply to the gas valve of somewhere between 150 & 339 VDC. The res should be 4.2 KOHMS between the outer two pins. Regards

Ideal Logic range are all 700mm high, 395 wide and 278 mm deep. Comes with a 5 year guarantee. They have Heat only, system and combis available in the range and all of the different outputs are physically the same case size. I have fitted all types so far (mostly combi's) in the last year...

Installers wont be able to specify B rated boilers from October the 1st 2010 onwards. However, installers can continue to fit band B boilers until April 2011, providing the order was taken before the 1st of October 2010. Oil- fired combination boilers are an exception to the rule. Its...

The pressure on the guage should be somewhere between 1 and 1.5 bar. There could be many reasons for low system pressure. My advice would be to re pressurise the system and keep an close eye on the pressure over the next few days to see if it drops. If it does drop and you then have to keep...

There is a cat that is using my back garden as a toilet on a daily basis. I have even had to fence off the lawned areas to stop my young nieces and nephews from playing on it. Whats the best form of repellant for cats? I have used pepper, but it washes away with rain. I have seen motion...

Isar's have a hot water pre heat facility that fires the boiler up periodically to heat the plate heat exchanger up. If for example you are not using anything (heating or hot water) you will find that the boiler will and should fire up every hour and a half or so. You cannot switch the pre heat...

Latest quote is over 900 quid. Its worked out by rateable value, which is rather unfair. IMO it should be done on turnover not rateable value. We have a large club but also a large car park and rear garden. We struggle at times with numbers who drink in the club and lose buisiness due...

Sorry if this is the wrong place to post this but i have a satelite tv question. The social club that i run is having a few financial problems and cant afford sky sports through sky as it cost us nearly £1000 a month. Does anybody know of a legal sports broadcast via satelite that would...

The internal fuse is a 3.15 amp fuse. Regards

As 5tIMES said, dont trust an electrician working on a boiler. H n is definately reverse polarity, its the only reason this fault comes up. You wont need a new boiler. Get a second opinion from a registered gas installer who will check the polarity at the boiler. He will find 230VAC...

Of course, all people that have fitted Logics MUST work for Ideal, because for what other reason would we fit one :roll: Try one, then comment and see what you think afterwards. I dare you !!!!!!!!!!! :lol: Regards

To slag off a boiler as crap without installing one is very harsh. IMO all boiler manufacterers have had problems in the past and we have all probably been stung by a boiler that has let us down badly. I could name other boilers that have let me down but i refrain from doing so as i am an...
