This post describes how to make a condensation free bathroom mirror using an automatic mirror heater. See the one I made in 2007 here. Look carefully and you will notice the condensation around the edge but not in the central heated area.
Without a heater it would be impossible to use the mirror without first wiping it with a towel. Cold mirrors usually mist over again after wiping.
We are all trying to reduce energy costs and CO2 emissions by choosing modern alternatives to incandescent lamps. Here are some lighting charts to help you select the best lamp for your situation. Since the decline of incandescent lamps there have been many alternatives made available based on fluorescent tubes bent in many ways to condense a long tube into a confined space.
I had my first Philips SL prismatic Compact Fluorescent Lamp (CFL) lamps soon after they came on the general market back in the 1980’s. I only recently sent my last one to recycling after deciding that even my shed could do better than have one of those long time warm-up devices.
In the early days of low energy lighting there was nothing better than the good old fluorescent tube, usually confined to kitchens and garages in the British house. I still had two twin fluorescents in my kitchen until 2015. If you want the room lit without shadows that’s the way to do it. After much searching in 2003 I found some streamlined fluorescents fit for the modern era to replace my old fluorescent ‘chunky boxes’. Unfortunately they went off the market and I struggled to find a decent looking replacement that didn’t cost a fortune. There were some problems with the ones I used. They had a self destruct mechanism built-in. The plastic fixings for holding the wires in place on the frame all deteriorated under the ultraviolet light given out by fluorescent tubes. I replaced them with zip ties but they suffered from the same problem.
To get back to the point of this article, which is to advise on the brightness of replacement lamps, I have chosen to publish a chart by which seems to relate to the UK/European market and another by which relates to the American market and appears to suggest their lamps emit more light than European lamps, e.g. UK/European 100W ≅ 1300 lumens, American 100W ≅ 1600 lumens (see A USA Lighting Chart).

This article advises how I have replaced a Mira Shower thermal switch in a MIRA Sport 9kW Thermostatic Shower on several occasions.
Originally I installed a MIRA Sport 9kW Thermostatic Shower as part of a new bathroom and had it tested and certified by a qualified electrician on 1st May 2007. I was very pleased with it and it worked well for three years until June 2010 when it developed a fault.
I found that in the middle of taking a shower the water would go cold for a few seconds and then get warm again. On the first few occasions I wondered if cold water being drawn off by other taps and appliances was lowering the water pressure to the shower and so causing it to operate incorrectly (although the low pressure light was not illuminating). As the days went by the problem got worse and my wife ended up washing shampoo off with cold water. I knew then that I would be in bad books until it was fixed.
I had to determine if this fault could be fixed or if I would have to replace the entire shower unit. For this I needed to take a look inside the shower unit.
In the northern hemisphere solar panel orientation is unsuitable because they mainly point south. This enables them to generate the most electricity when the sun is highest in the sky and is shining straight down (or as near to that as possible) on the surface of tilted panels. This approach does allow the panels to generate the greatest possible amount of electricity, but not at the best time of day. This is because there are problems connecting intermittent sources of electricity to the grid. It seems midday electricity isn’t required so much as afternoon electricity. (I’m not sure what is required in the morning.)

This post is about the Ring Automotive Air Compressor RAC900 which is an excellent pump for inflating anything with a Schrader valve, (e.g. car tyres, bicycle tyres, etc.) or balls, airbeds, etc. (3 attachments are supplied). It has to be powered by a 12 volt (30 amp peak) supply such as a car battery (not provided). So to use it with a car the bonnet must be opened and the battery cover removed to expose the battery terminals for connection. I don’t think it would be safe to connect it to a cigar lighter socket. It does come with an inline 30 amp fuse.
A few weeks ago I passed a friend in the street who was inflating his car tyres on his driveway with a Ring Automotive Air Compressor RAC900. He was very eager to show me his new tyre pump which was powered from his car battery. He explained how it had the following advantages over other tyre pumps:
It inflated tyres very quickly.
It had a built-in pressure gauge.
It was very well-engineered.
It came with a long yellow curly plastic pipe to reach all tyres on a car.
It was very quiet compared to other 12 volt air compressors I have heard.
