    The oil supply is separately earthed back to the house distribution from the oil cut off valve.

    Run boiler electric cable through cavity to outside.

    I meant 'through the leaves' to mean through the cavity in conduit. Is this acceptable?

    Isolating switch for external oil boiler

    We are having a new oil boiler outside. Fitter says put rotary isolator switch nearby. So we have one from Screwfix CPRSD425. My questions are 1. Can the existing internal boiler cable from the controller which is a ordinary 1.5mm cable be rerouted into the isolator through the cavity wall? 2...

    Run boiler electric cable through cavity to outside.

    Isolating switch (IP65) outside with the control flex within a plastic conduit. The job is to move the control cable for the boiler from inside (old internal boiler) to new external boiler direct through the leaves sealed. Is that OK? Should I uprate the flex (although it is effectively a...

    Coal bin opening door

    I have a plastic recycle bin (UK type with green lid if you know what I mean). I want to use it to store solid fuel pellets for my burner. Got to make a sliding (up) door at the bottom to dig out the fuel. I know I need a 'flap' inside to stop the pellets jamming up at the entrance but not sure...

    Porch Roof Size.

    I want to build a porch roof over my front door. It's a peak with ridge. How deep must it be from wall to end of batten if I use Marley concrete tiles (I think their about 420mm long x 330mm). I am aiming being about one metre deep but must adjust for tile width. Thanks.

    Porch Canopy Design.

    Trying to think out a design of a canopy but made up with UPVC Facia and commonly available products. Has anyone done this and can give an idea of the design? I want it peaked so the rain does not drip at the front. I intend to use glass for the roof part. Thanks for any pointers.

    Feed to outside oil boiler.

    The boiler spec asks for a proper protected outside electric supply. I take it the house ring will suffice with a cct breaker socket and plug. Will it be OK to make use of an existing socket and run a cable through the wall to the boiler or does the isolation switch need to be outside. Note the...

    Cold feed dribbling.

    AHHHH, I see! The gate valves I have on the output of my cold tanks do close but they get clogged with scale. One of them did close off fully again when I operated it a number of times. The other persists in leaking. Yes, siphoning then If I close off the cold feed valve nearer the hot tank that...

    Cold feed dribbling.

    If I close off the cold feed in the loft (feeds hot tank floor below and bathroom) it dribbles and eventually lukewarm water comes out. If I let that run long enough there is an air lock in the hot feed when I restore the cold. Am I right in thinking that the dribble is water coming up from the...

    UPVC Patio Door Security

    I have French Doors. The main door locks OK. The second door (usually closed) has a lock and key but does not lock. Even with the main door locked, although it keeps the second door from opening, the handle on the second door can be pushed down. So it has a mechanism to keep the door in place...

    Gate Valves

    Are they directional? It says on the packet to follow the arrow. But there is none and it looks symetrical inside to me!

    Situation of CH header tank

    At what height should it be relative to the main water tank in the loft. I was thinking if the HWTank got a leak in the coil and the CH header was below (like placed on the same joist level) the main water tank then water would flow into the CH header and spill (probably faster than the overflow...

    Need to move oil boiler.

    U10-17-11-08-58-R321 Here is my current flue stack belching fumes into the garden. I want to put the boiler against that wall (in a utility housing). And then take the stack up to the roofline. Would prefer a black finish. I think these are insulated pipes with air in at the bottom. The boiler...

    How can I prove cylinder coil leak?

    HW Cylinder. Thanks. Thinking about this as the CW tank in the loft is on the same platform as the small CH filling tank then if there was a leak in the HW cylinder coil this small tank would overflow due to the water level in it being far lower thn the CW tank next to it. Am I right?
