The latest boiler problem to develop on my potterton performa 28i is that it requires resetting but there doesnt seem to be a pattern to the amount of times it requires re-setting. The boiler has never had to be reset in the past. During last week there were three mornings when the boiler had...

ok to be exact the guide says check elec and tube connections, check for blockage of pressure tubes, restriction in flue and check venturi - if not any of these change pressure switch

how can you tell if the venturi is no good? - is there a test you can do?

i understand what you are saying but I am an engineer by trade and to remove two screws, three elec conns and two tubes and replace the pressure switch why would I need to call someone out. If this doesnt work then I would call someone out.

Hi, I had to drain down my system yesterday to remove a rad. When I re-filled the system the boiler would not fire up. The fan neon light was flashing - (fault guide says problem with air pressure switch). I opened up boiler to find the band clamping the fan outet elbow to the flue had...

Hi, I have run two armoured cables between a new detached garage and the house. I would like to know the correct terminal boxes/glands to use to route the cable through the house wall. Do you use water proof boxes on the outside and then strip away the armour and only route the cable through...

I didnt realise I had so much concrete to go through - so thought about plan b!

I have tried to route the pipes today down inside the house and then out to the brown soil pipe in the channel I have dug. I have hit a problem that I have about 8" of concrete to go through. What is the best method if I take the pipes out at floor level and then drop them down to the pipe...

thanks I think this sounds the best bet

Hi, I am having a detached garage built and I want to run a cold water pipe and CH feed and Return to the garage through an underground trench. The trench is around 4m long between the house and garage. I have dug down around 3 to 4 foot deep and plan to run the pipes inside some brown soil...

I did originally plan to supply the current consumer unit - but since reading threads it looks like a better option to insatll another consumer unit and just power this.

Hi, Can you tell me how to calculate the size of changeover switch for my generator. The generator outputs max 2.8KVA rated at 2.5KVA - 240 volts. It says 16 amp output socket Can you tell me the size of switch I require - I was looking at the TLC changeover switches - I presume 32A...

Thanks for the link. - Do you get switches with a power light built in so you can see when the main supply is back on?

manual - its only for a back up supply as we do get power cuts from time to time - The generator isnt that big and we woul donyl use it to run ch pump couple of lights etc. What the difference between switching off circuits you dont need through flicking the switch on the consumer and fitting a...

Hi, I am trying to track down a transfer switch so I can connect my generator to my house supply. I have been searching on the net but havent found my options. The only one i can find is a briggs and stratton with a 13 pin plug socket on it. Its quite large and I dont really want it to be tht...

I am building new. The plans are passed but we didint need building regs as the garage is under 30sq meters. The building is going to be a garage but its going to be built with a cavity wall and insulated as best as possible. We plan to use the room as a kids play room in the future - kids only...

what regulations are their about the ch feed and return pipes leaving the main house and going underground. I suppose the best way is to take them down in the house first and then out through footings. Can you go out the wall and then down? - I suppose the only risk here is that they would be...

Top man Dave thanks

Hi, I want to check my HW diaphram is ok as the taps have to be on full before the boliler kicks in. Can you tell me what I have to do before I can remove the cover to check it - drain down sequence etc. I have changed this in the past but cant remember the sequence of events.

Hi I didnt end up fitting UFH - I went with myson kickspace heaters in the end.
