I have been working on diy projects for a while. Thought about saving energy etc. and i got an idea. Most of our a/v appliances have tranformers to give dc power to the circuit boards . so i thought about saving energy by hacking my tv to test my idea. I found the main power supply and tested the dc output and found it to be 12vdc. So i took apart a pc power supply. ...

Does anyone have any tips for a good brand of energy saving washings machines or dishwashers available in the West Midlands?

Thanks in advance!

 Post subject: Cavity wall insulation when building blocks are insulated?
PostPosted: Thu Jul 13, 2017 9:03 am 
Hello :-)

Just a quick one...

I live in a private 3-storey apartment block and the managing agents are in the process of arranging cavity wall insulation. Presumably, the cost of this will eventually be passed onto the residents.

According to the NHBC Home Owners Information Card still in my possession, the type of wall insulation used was 'Thermal bond block' when Tay Homes built the place ...

 Post subject: Sunamp Blogger Asking Some Questions
PostPosted: Tue Jun 20, 2017 9:39 am 
Hey there,

I am new to this forum and was hoping to ask a few questions.

I am student on an internship at the company Sunamp, a company who produces heat batteries which are similar in concept to the Tesla electrical storage device but instead stores heat instead of electricity.

They are a growing small and medium sized enterprise (SME) and are growing in size. They have taken me on board to promote the company ...

 Post subject: REAL Green Energy?
PostPosted: Sun Jun 11, 2017 7:19 pm 
Green/Renewable energy is becoming more widespread and I don't want to debate whether that is good or bad and the reasons behind it. What I'd like to hear thoughts on is what I call REAL green energy, which to me is alternative energy sources that are actually useful but also cost effective.
For instance, you can cover your house in solar panels if you want, but the actual payback period on that is so long ...

 Post subject: Wind turbine
PostPosted: Sun Jun 11, 2017 10:56 am 
Just wondering, have any of you (or folk you know) got a "wind turbine"
If you have, which one any good etc?

I was thinking of getting one just to see what they are like, I also know that despite what you may think they do need a fair bit of wind to make electricity, and this wind needs to be constant if its to be of any use, so all I was going to ...

...of energy saving.

We've seen recent reports of 'smart meters' being responsible for not-so-smart readings that have left some owners wondering why they've received bills in the thousands of pounds instead of their average normal usage. Well researchers in the Netherlands have been testing smart meters for accuracy and found that errors range from -32% to +582% :shock:

Conveniently (???) the error on the side of the ...

 Post subject: Bulbs, power, lumen, and savings how do you know if coned?
PostPosted: Fri Feb 03, 2017 11:54 am 
This is nothing new, around 1992 I was working on the build of Sizewell power station and my boss decided to use fluorescent tubes to light the tunnels, all were 110 volt units at ratting of 58W so quick calculation just over 1 amp for two tubes, so supply was 16A so 32 lamps would be just over the limit, so decided to fit 25 lights to each 16A supply.

Lights fitted 2 hours latter ...

 Post subject: Adding extra loft insulation beyond 270mm
PostPosted: Wed Jan 18, 2017 8:36 am 
Hi everyone.
My house built in 1972 had fibreglass insulation between the battens, I guess 100mm.
The previous elderly owner then used the government scheme to top it up to, I believe, 270mm. They also did cavity insulation. So currently, I can't see the battens, but I checked that they didn't block the ventilation around the heaves.
I see on Gumtree someone local selling few rolls of 100mm thick fibreglass. Would it be a good ...

 Post subject: Hole in the plaster board for stop cock letting in cold
PostPosted: Thu Dec 01, 2016 8:42 pm 

I've just moved into my first home and I'm in the process of trying to fix all the things that are broken. One of the biggest problems is that the previous owner seems to have cut a hole in the plasterboard by the front door to access the stop cock and value. This is now letting cold air pour into my home.

As a short term fix, I've stuffed it ...
