Hi Chris & John, thank you for your replies, here goes.... The price quoted is inclusive of VAT and the earth bonding will be to water only (already existing) as we don't have gas over in the Hebrides. We had a new meter installed in April along with new wiring from meter to CUs so we will be...

Hi, We moved into our house 3 months ago and the wiring into the consumer units (domestic & storage heating - no gas in the area!) looks like a nest of wires. There also aren't RCDs on either of the CUs, what's on each CB in the domestic CU is very random and we'll need 10-way boards anyway...

I don't want to cut the ceiling as it's also very difficult to get to a osition above the expansion tank. What I'm going to try to do is remove the cylinder overflow from the top of the tank so I can get the lid off then make like a contortionist to replace the valve. Would bending it down help...

Hi John, thank you for your thoughts! I have no mixer taps at all so the fault is with the header tank. There isn't a service valve although it is going to be something I plan to do in the future, as well as replacing the float valve. I don't know who put the tank where it is but there isn't...

Hi 45years, may I ask what your suggestion is based on? The header tank doesn't always overflow, just sometimes, and I don't know why? Would reducing the water pressure help? I could partially close the stop cock downstairs? Is there any way I could check to prove that it is actually the...

Hi, I have noticed that my hot water header tank has been overflowing and venting down the side of my house - I'd like to stop this but can't for the life of me figure out why it's doing this! Firstly, the header tank is situated in a utility cupboard upstairs as there isn't enough room in...

HI all! I'm trying to sell my old house which the surveyor has listed as of Dorran construction. We'll not mention that the survey when I was buying made no mention of it being Dorran and, in fact, stated the house if of 'Standard Block and Render' construction. Moving swiftly on... I have...

Hi Lectrician! Finally, sense - can you work for nPower please? Right, we have a teleswitch (Horstmann Series 2D) and the engineer even put a sticker on it saying that it was a teleswitch. We previously has prepayment Total Heat with Total Control (8 hrs cheap heating in any 24hrs, split...

Just had a thought - is this actually set up for Economy 7? The storage CU has just came on at 2155, way earlier than I would have expected. I also have no way of getting night rate on the domestic CU as it doesn't have a toggle between 'day' and 'night' rates on the meter. I have a horrible...

Hopefully these pictures are of some use. Please can you correct me if I have the following things wrong: We were told that, with this arrangement, at the appropiate time, the radio switch would - 1. switch to the cheaper overnight rate and, at the same time, 2. provide power to the...

The connections between the radios switch (Hortsmann Series 2D type NU045-9003) and my meters (Landis Gyr 5258K) and my consumer units (domestic & storage)

Hi all! I’ve just recently had my prepayment meter replaced with an Economy 7 credit meter on nPower. I would imagine that it would provide power to the storage heater / main immersion heater consumer unit under the control of the radio teleswitch, giving 7 hours of heating sometime between 2200...

Snug, thanks for telling me that, I tried it and it made no difference. However, I did turn the speed of the pump down from 3 to 2 which seems to have sorted it. Any reason why it woudl thud when hotwater is selected on speed 3 but not thud when heating is selected on speed 3? i can see that...

Can anyone help? The thump only happens when I've had the central heating on and, once it's off, when I turn the hot water on. There is what appears to be a bleed screw by the inlet to the hot water cylinder, have opened that until water comes out then re-tightened it leaving only the holes...

Good Morning! I've noticed recently that when the boiler comes on to heat the hot water, if the three-way valve has been to heating, that there is a thumping in the pipes as the hot water starts flowing. I've got a header tank in the loft so would that be causing air to get into the system...

Thanks for your replies, I wouldn't touch the boiler as I know nothing about gas apart from you cook with it and use it to get warm - and it's best to leave to the professionals! When I get it serviced I'll mention it and get the burners checked. Thanks again!

Hi all, Just had the boiler (Baxi Bermuda 401) on for central heating and my girlfriend sitting in the living rooms says it made two small popping noises after it'd been around 10 minutes. The boiler appears to be operating normally, ie blue flame, pilot lit as normal and cycling itself on...

Hi Alistair, I think their may be some insulation as when I drilled through to install the outdoor tap it appeared that their was some polystyrene attached to the inner face of the outer brick wall. I don't know how efficient this is alone and don't know if this is cavity wall insulation - I...
