Was just looking at the technical manual for the burner and it seems that the pump pressure setting for Kero is pretty much always the same (8 bar) for all flow rates and it is the selection of nozzle that controls the output. Given that the pumps are factory set to 8 bar and it's the same...

We have a Riello 40 G3B oil burner coupled to a warm air central heating unit. It has been acting up recently - first the motor stopped working a month or so ago; it had been sounding like a strangled cat on startup up for a long while, but replacing the capacitor did the trick and it was...

Thanks for the advice. I think I will give it a go. In terms of connecting up I assume I could split the flow and rerturn to the towel rail into 2 and use that as flow and return for the new pipework. To control I was thinking of somehow putting a thermostat option in - either a TRV mounted in...

We have two upstairs bathroom with tiled floors laid on plywood boards over the existing floorboards. In one of them a lot of the pipework to the hot water cylinders and towel rails runs under the floor and as a side effect the floor is always warm. In the other, there are no pipes and the...

We have two large(500l) cold water tanks with ball operated float valves that have started leaking due to ball valve not shutting off completely. Valves are about 6 years old. Rather then just replace them or some washer I was wondering if there were any alternatives that are more reliable...

I am in a rented flat which is roasting hot all the time and so bought a portable air conditioner. It needs to be vented to the outside. At the moment this is going via an open window, but as we are on 6th floor with a 3 year old it's not ideal from a safety view and there is also quite a lot of...

I had a similar problem with a white powdery residue being left behind on the plates after washing. At first I also thought about limescale, but was puzzled because we live in a very soft water area - there is no scale in our 8 year old kettle for example. However I have found the actual cause...

Thanks to everyone for your replies and advice. The reason for wanting RCD on the lights is to help reduce the risk of death by electric shock. In the past year there have been two occassions where I thought there was a risk of getting a shock from the lights - changing an upstairs light...

We recently had our old CU replaced by a new split load RCD one. The split part seems to mean ring main circuits are on RCD side and lighting circuits are on non-RCD side. I understand the reasoning goes "if you've just tripped your RCD, perhaps having touched a live conductor, you don't want to...

We are having a steel frame balcony constructed and want to cover it in wooden decking. The frame is made from T section steelwork and these would provide an open span of 870mm for the deck boards. I looked on the TRADA web-site...

Is the pump running (feel the casing to check for vibration). Does the boiler light up.

But if the hot is pumped and the cold not then it won't be balanced. Was hoping mains cold and pumped hot would be good enough match. I know ideally you pump both or pump the blended output from the valve, but both of those will require breaking into the tiles and messing about with floor...

Possibly an air lock on the boiler - I had very similar problem last night. Was solved by loosening the screw on the CH pump on the boiler to bleed it.

Can you supply mains cold and pumped hot to a thermostatic mixer shower. If so, do you need a non return valve on the mains to the valve; do you also need one on the hot and if so, which side of the pump should it go ?

If I replace the cylinder with an normal indirect one and add a new F&E tank where do I connect the feed and exp. pipes. I am presuming the feed could tee into lower pipe of the cylinder coil and the expansion into the upper, but does it make any difference or do they have to go down to the...

Thanks chaps (I assume you're chaps); I'll see how I get on with the Treloar and then maybe check the others out in the library.

You can always offer to restore his system to how it was before. tell him to shove it chris i was cought like that a few times other alt is you dont pay me for what i do you pay for what i know :cry:

Thanks Chris. Have ordered the Treloar book and one on IEE wiring regs. The WRAS will have to wait for a while. I think my parents will be OK though - as a child I had a chemistry set and tried to make stink bombs by mixing everything together and adding a load of vinegar. It didn't work and...
