Re: I don't see any lintels in my house

...and, assuming metal ties have been used to tie the inner wall to the outer wall, this explains how I managed to burn out my mortar removal tool when I was trying to repoint.

Re: I don't see any lintels in my house

Yes, I suppose there would be; the window's only in the outer skin.
The mortar in the brickwork above the one window is cracking, but it's only between the bricks of the soldier course.

I don't see any lintels in my house

Hi. When I bought my house, all but one windows were double-glazed. I got the one remaining window measured up and the fitter came to install it. First thing he did was knock out the existing wood frame. I noticed that it seemed to be build in the fabric of the house and that there didn't appear to ...

Concrete Paver as a BBQ Fire Base

Hi. I'm planning on rebuilding my brick barbecue. In the last few years, I've gone through two steel firetrays. They get heated, cooled, left out in the rain... I'm not surprised they burn out. I've noticed that some folk pour their own concrete fire trays. I have sourced a 900x600 50mm thick concre...

Re: Smart Technology - Are you Getting any use From it?

I'd have to say "no". This is absolutely not a consumer-ready solution. As far as being ready for a commercial enterprise, well, it would need to be a large enterprise to retain a full-time specialist. 737-MAX. Yes. Unfortunate. A pilot's eyes should always be able to take over from a pair...

Re: Smart Technology - Are you Getting any use From it?

Home Assistant is a very good web interface, but other than adding instruments, I find it very difficult to understand. In fact, I have an MQTT postprocessor in Python which reformats the topics for me to use in Home Assistant, because I can't be bothered figuring out the jargon!

Re: Is Radiator Balancing Really Necessary With TRVs Installed?

OKay, I switch the heating off for a couple of hours, and let it cool. Then I opened up the TRVs (except one I forgot) switched it on and estimated which rads heated up the quickest. I turned the two very hot ones down a quarter on the lockshields, then the next 3 down a little nudge (there are 12 r...

Is Radiator Balancing Really Necessary With TRVs Installed?

Hi. My home has Thermostatic Radiator Valves installed on all the radiators. the system hasn't been serviced in a while and I drained it down, filler it up with a flushing agent, drained it, flushed it with clean water and finally refilled it with an antioxidising agent. One reason for doing this wa...

Re: Smart Technology - Are you Getting any use From it?

Wish I'd seen this post some time ago. Could have contributed. these are all great points. But there's more. Yes, the "standard" which underlies these devices doesn't tie them all together well. (Or at all, in some cases.) Importantly, everyone will have different expectations, and you'd n...

Re: Basic Central Heating Operating Principles

Of course, this assumes the radiators are in "series". My old house had microbore pipes running from the boiler to each radiator, making them effectively "parallel." This type of setup might also answer your query.

Re: Basic Central Heating Opperating Principles

Not a clever stopcock, rather each radiator has a bypass pipe. I have one or two radiators which are quite high above the wall, and each has a pipe running from one end to the other and the radiator is attached to it by T-pieces. As such, when the TRV, or the lockshield valve is closed, the preferre...
