A heating engineer suggested that in general external wall mounted condensing oil boilers give more problems than a floor standing external condensing oil boiler even of same brand. He suggested this might be due to manufacturers attempting to cram the same components into a smaller space. Any...

I was watching the video below by Which? about wood burning stoves. The still shown below shows the hearth.; it looks more or less level with the ground. I believe the hearth is required to be of a certain thickness to comply with regs, though the is 7 years old so perhaps different requirements...

If prepping a fireplace for a wood burner, would I be right in thinking it's best to install the brick slips against the 3 internal walls of the fireplace first and then lay the hearth into the fireplace after this. Otherwise, if the hearth is positioned first, then when the brick slips are...

Thanks for that. I'm not a plumber so I'd just assumed all the pipework would all have to be copper in a sealed system. Interesting that certain pipe/fittings manufacturers may produce plastic pipes/fittings that can be used in a sealed system.

If a sealed heating system (with unvented hot water tank) is put in place can: a) either plastic or copper pipework be used? b) since system is "sealed" does this make it more complicated than it would be otherwise to either remove/replace a radiator to the system in the future? Thanks.

From what I can see the primary difference in these two boilers is that the System version is that "System models are supplied with a factory fitted expansion vessel, filling loop, pressure gauge, automatic air vent, pressure relief valve and high efficiency circulating pump enabling the boilers...

I can only think of two which start with a W. These, and of course WB. What other brand do you prefer?

Given that there's only about £100 difference in price in these two external combi oil boilers, and both are physically the same size, I guess may as well just opt for the second one, the E26C which has a higher flow rate of 22 L/min (compared with first option of 18 L/min). House has 3...

What minimum height off the ground would a home heating oil tank have to be to allow gravity feed? Thanks.

I just had a look at the Quickslide, VS express, R9 and Rose Collection websites and yes they don't appear to have horns on the top rail of the lower sash either. Disappointing if wanting sashes to look as original as possible.

I had a look at the Victorian Sliders website. The upper sash does have horns on the lower rail and so are visible externally; however, the lower sash does not appear to have horns on the upper rail and so there are no horns when the window is viewed internally. If they're wanting to keep...

Would anyone be aware of any other brands of uPVC sliding sash windows which have continuous run through horns, other than the two below? Thanks. The Rose Collection https://www.sashwindowsuk.com and R9 sash windows That is, in order to avoid an obvious joint where horn meets rail such as below.

That's interesting. If I look around my local area I see many 1st floor bedroom windows in residential houses which have casement uPVC windows with top openers only and would not allow escape. As a result I'd just assumed that only one escape window was required on the 1st floor; I'd also...

Presumably the means of escape from any habitable room could be a fire escape window located in any one room of the 1st floor of a house, and not that each room on the 1st floor has to allow escape? (I'm referencing only a standard 2-storey house).

Thanks. Yes, well one window upstairs would have to open fully as a fire escape, though would this be restricted to one window upstairs? Presumably people don't have fully opening windows such as this in a 1st floor bedroom that would be used by a child?

There are obvious safety issues with regards to having windows such as those shown below on the first floor of a house. I was wondering if anyone had any thoughts on safety issues? Should this type of fully opening window only be installed on the first floor if the bottom of the window is a...

I guess that is non-hydrated lime. I had looked lime up on my local builders merchants website and they only had hydrated lime, but easy to get sand and cement.

To achieve the lime mortar does that simply mean adding hydrated lime to a sand/cement mortar mix? Out of curiosity, what is the benefit of adding lime?

Is mortar or a tile adhesive used to adhere brick slips to the walls inside a fireplace?

What tools would be required to produce some brick slips? I'd only be producing 100-150 slips as a one-off DIY job, so I wouldn't require high end equipment. I've cut through some bricks in the past with an angle grinder in order to cut them in half, but the finish of the cut is not of a quality...
