Hi Eric - thanks for the reply. The problem is we've used this boiler for 10 years and it only started this a couple of weeks ago, so something has changed. My question really is what could have changed/be malfunctioning to cause this effect? For what it's worth there's also a pump on the hot...

Hi I'm fairly handy but don't know boilers so well so please excuse me for any schoolboy errors here. We have a De Dietrich (model F67110**correction** - apparently this just means a French-made model. There are 2 "type" numbers on it: GT/GTM/GTU 1104V and MT 130) oil-fired boiler which...

I've taken oilhead's point about pumping it out without moving the tank which makes sense and will reduce any risk of damaging the tank. The only laws that apply here are in relation to disposal of sludge which I'll do properly by taking it for treatment. But the cost of that is about €50...

Thanks Oilhead. Can I ask what you mean by "A contractor with the right equipment would get most of it out before putting any spray into the tank"? Do you mean there is an alternative treatment that involves not using a power hose? If so, what would it be? thanks

Hi Apologies if this thread is in the wrong section but I hope it comes under the "central heating" header. I have a plastic domestic fuel tank (for our fuel boiler), 1500L which needs cleaning. The quotes are coming in ridiculously high so I'm considering doing it myself. The tank has 4x 7cm...

For the record, in case anyone else finds this thread, I set up the system with both fuel boiler and electric emersion heater joining the hot water supply tap for the house. Works a treat. Mix is roughly 50/50 and we can turn off either boiler to make it 100% either system. Gives our system a...

gasguru - why do you assume it would be unsafe? What is the worst case?

Thanks for the comments. Yes I could see taps working in certain situations but the aim here would be to have the water heated by 2 different sources (roughly 50/50) rather than just one or the other.....

Hi This is a theoretical question for now, so no need to worry about the "whys" of the situation! If I have an existing fuel-fired boiler providing the hot water to a tap, and I "T" in another pipe (to the pipe going from the boiler to the tap) supplied by an emersion heater, will the water...

I would guess glued....it was sold with the backing on it so is intended to be a single item....

Because the mirror is flat-backed so anything I'm going to attach it with is going to have to stick out from this flat back - whether hooks, a clip-system attached to the wall etc.....It's just about flush to the tiles when I hold the mirror against the plaster (the mirror will then be...

Yes I know screws are the conventional way to mount mirrors if they are taking the full weight, however given the mirror will be adequately supported from below by the tiles, all I need to do is "stick" the mirror to the wall - the glue/adhesive/something else will only be stopping the mirror...

Hi As the subject says really, I have a 1cm thick wooden-backed mirror - when I say wooden it's the type of painted chipboard (I think) you'd get in a flat-packed wardrobe - which I need to mount in a bathroom. I picked the wooden backed one because it leaves the mirror pretty much flush...

Hi There I'm considering insulating my attic floor to save energy etc. However my house has 2 floors with 3.8m (about 13feet) high ceilings on each floor, so my question is, will attic insulation make any real difference or is it just going to keep the top of the room (which is too high to...
