Hi all I have a Vaillant Ecotec Plus 837, around 10 years old. The CH has been running constantly, and I thought originally this was a fault with the timer/thermostat (Drayton Wiser). I have disconnected the external timer (Drayton heat hub), and fitted a used Vaillant mechanical Time switch...

I'd appreciate some advice with wiring for a Drayton Wiser Heat Hub. I have a Vaillant ecoTec 837 combination boiler, currently controller by a Honeywell programmer in the hallway. On removing the Honeywell controller, it appears it's connected to the boiler with only 2 wires (a permanent live...

I'd appreciate views on the following please My father needs a new oil fired boiler to replace a very old one. The existing boiler is located centrally in the property, and is flued via what appears to be a stainless steel flue liner which routes up the original chimney. I would estimate this...

Hello all I have 2 lights in a room, switched by a single switch. I would like to be able to switch the lights independently of one another. I have unscrewed the light switch, and there appears to be 3 x twin and earth cables entering the box (presumably one for each of the existing...

Hi all, I have build a new stud wall and plasterboarded it. Should I do anything specific (before plastering) where the new wall meets the existing wall at right angles to stop cracks appearing? I was wondering if I need to use a flexible filler before plastering or something? Cheers

I need to lay a new plumbing pipe in my loft conversion, which will require me to lift up about a 4m run of flooring. The flooring is t&g chipboard, so I can't see where the joists are. Am I best off locating 2 joists and using a circular saw to take up a section between 2 joists, our do I have...

My Vaillant Ecotec 837 (c. 9 months old) makes a loud 'clack' sound when the CH pump overrun stops. Is this some sort of valve closing, perhaps? Is this normal, or should I ask my installer to come back and take a look? Thanks

I have an issue with my water supply. I have a combi boiler (no stored hot or cold water) and if a tap is opened (or toilet flushed etc) whilst showering then the shower slows to a trickle. This is extremely frustrating :x The problem is exacerbated by having a loft conversion with an...

I need to construct a stud wall which runs directly underneath an (existing) RSJ in a converted loft. How do I attach the head plate to the RSJ? The steel is already clad in in plasterboard - should I remove this to expose the steel in order to attach 4x2 head plate somehow? Thanks in advance

Strange question I know, but anyway... I'm redoing my bathroom and am buying a new wc. The existing toilet doesn't flush well, and seems to lack power. Can anyone make any recommendations as to decent syphon/flush mechanisms? My experience is that not all these are created equal! ta

Hi all, grateful for your opinions on the following please: 1. I have several uPVC glazed windows, a couple of which seem to have gone 'cloudy'. Close inspection shows that there appears to be moisture between the 2 glass panels. I am assuming that these are sealed units and therefore...

Hi, just wondered if anyone is able to offer a word of advice. I have the above boiler and thermostat combination, relatively new (<1 year) - and have noticed that sometimes the thermostat starts the boiler (as the room temp falls), only to stop it again a minute or 2 later. The CM907 makes...

I have a bit of a dilemma. I am just about to create a large-ish open plan living area in my house (36 square metres) and I would like to install a (warm water) underfloor heating system. The existing floor is a suspended wood floor (I should mention house is approx 100 years old) with a...

Guys, just moved to a new place. Boiler is a Vaillant combi about 8 years old. I've not been using the CH yet, other than to test it, and all seems ok- all the rads heat up. This issue is that 2 of the rads upstairs heat up when I'm drawing hot water. The effect is particularly noticable when...

Hi, I'd like some advice on laying an electricity supply to a garden shed please. Shed is standard wooden shed, and I would like a single light bulb, and a single mains power outlet socket. So the requirements are quite basic. I will not be using any high-usage items into the socket -...

All I'm ordering a new hot water cylinder from the manufacturer (as the dimensions I need do not seem to be available as a standard order). The manufacturer wants me to specify the tappings. There seems to be a choice of various sizes of "BSP" male and female fittings, along with...

Hi I have been quoted £450 by a surveyor to draw up a design for a single storey, sloping roof rear kitchen extension for my mid-terrace house. The price includes calculations for the dimensions/specs of an RSJ to support the existing back wall. I've been told no planning permission will...

I'm doing a bit of planning ahead here. I have a Potterton (conventional) gas boiler in the loft, which by the look of it is quite old. I'm not that comfortable with it in the loft, as I can't keep an eye on it. This probably seems completely irrational; as I'm sure most people don't...

I have bought 3 spotlights for my bathroom (IP65 rated), and would like to know the most appropriate way of wiring them in. I have existing wiring and pullcord switch in place from the old (single) bathroom light. I have bought a transformer for each light. Can I do the following: -...

I have just tiled my bathroom, and have been advised to treat the porcelain tiles with Lithofin FZ Protective Impregnator, which is supposed to make them easier to keep clean in the long term. Should I apply this to the tiles before grouting, to protect from the grout; or after; to protect...
