    combi conversion

    As you have microbore pipework to your rads, (either 8 or 10mm?) the combi would certainly need to be connected to the main circs, (or new circs fitted of course) so your most probable locations are either where your cylinder is currently or your boiler, Cylinder location has the benifits of...

    Can you turn a flue ?

    I'd definatly get another quote for a boiler though as BG's quote seems a little steep *shrug* I haven't seen the job, mebby it justifies 3 grand, another quote can't hurt thou.

    Viessmann boilers + Can I do all the work apart from the gas

    doitall: pathetic isn't it, we are only competent when there is a middle man, I'm going for my indervidual corgi this year as I'm getting a little annoyed that I'm not corgi registered if I look at my mothers boiler.

    Frost Stat

    check the frost stat for operation, see if it has just been set too high and needs turning down a little, you can just disconnect the stat for normal boiler operation, howerver a speedy replacement would be a good idea. A frost stat fires up the boiler when its ambiant temp is a few degrees...

    Sime with explosive ignition.

    I honestly can't remember, but last time I was there I checked the pressures with the data plate (which is in italian) and all seemed fine. No pilot, it ignites on the burner bar, (checked electrode gap, spark lead continuity)

    C/H Pump over tightened screw?

    No. A tweak tighter then when the water stops It'll be hard to get it out again.

    Got a working gas cooker? check the meter isn't an empty prepay (my most common fault when going to (until recently) uninhabited flats.

    Sime with explosive ignition.

    I have a 5 Year old, Sime Family RX55CE IONO, I've been told by Sime they don't make it, eventually got through to the technical of the actual manufacturers who said it was a gas valve fault (not ramping correctly), (I'd had already checked & cleaned the spark electrode, jets and leads) and...

    boiler over heating

    for two different things, you also have a room stat as well, 3 different temp settings? and one on each of your radiators? 10 temp settings in your average house, obviously they all control different things ;) TRV: Sets the temp of the room at which the connected rad will shut off. Room...

    Purpose of Gate valve on hot-water tank

    No. it should be cracked open by the installing engineer who should remove the head from the gate valve so that it can't be tampered with. Open it too much and you will loose a large percentage of your flow through your rads/cylinder, close it and increase the possibility of kettling and...

    fitting a new h/w cylinder

    and indirect with a cold water storage tank attached to the top is a combi cylinder, does it currently have an indirect cylinder fitted? (fed with two heating pipes a pipe from the water tank up in the loft and a pipe on the top to your taps) A direct replacement isn't too hard as long as...

    High pressure on combi boiler

    Radient were a bit (read: considerably) crappy to work for from what I remember. I'd see ph's bet because a flat xvessel doesn't affect the pressure switch, which was your complaint, not the boiler's pressure raising wildly when hot. (at 2bar it should be mainly full of water anyway) You...

    bury pipes

    People seem to be in two camps over warm air heating... some of my customers adore their 30yo warm air system, I also get others who have just moved in and hate it and want it replaced (I've only had one so far that lived with it for many years and wanted it replaced with a wet system, to my...

    Worcester 24i -V noisy after powerflush & new pump - Lon

    Good analogy but I'd have thought it closer to DVT followed by a stroke. (as a sidenote) I've always found as long a suitable chemicals are used with my good ol' Kamco, it'll shift anything, but I'll look into vibration methods as I can understand how this would speed up the flush, which...

    High pressure on combi boiler

    As long as it isn't firing through the PRV, I wouldn't worry about it too much, I can't remember a radient model with a gauge, (as far as I remember they all had an electronic display which just tells you if the pressure is between <0.7 / 0.7-2.0 / >2.0) Check that your filling loop is...
