The problem with this is that a lot of people will think he is an 'expert' and will be put off from using MHRV. They may also think because it's not worth installing MHRV it's not worth building airtight.
We've had a Harveys, a Kinetico and a Twintec over the years. The only one to give any problem was the Twintec although I liked it because it had a see through cover over the salt container. Wrekin Water Softeners do their own version.
Why not discuss polytunnels. I built one once as a temporary store for a classic car and there's plenty said on here about classic cars. What's the question?
We fitted Schneider Lisse because we liked the look of them and the reviews were good. The light switches are good in that they have a loop-in terminal built in.
Does anyone know of a supplier of flame retardant meter boards? Online I could only find CEF and they didn't reply to my email and in a CEF store I was told they couldn't get them.
Our BCO and the Highways Dept. allowed us to discharge roof drainage directly onto the lane because of the very variable water table level. There's not much point in SuDs down here, the lane is the drain.
In 1970 when I first started at the MOD I programmed in a language called MIRFAC which was run on an inhouse built computer called COSMOS. IIRC I took the instructions over to the ladies in the computer centre who punched out the cards and ran the code. Cards then changed to paper tape. COSMOS was replaced by an ICL machine running George4 I think, it's all a bit vague. I remember the calculators were electro-mechanical and when the first electronic ones were bought soon after I joined they cost a fortune and the following year they were half the cost and could do twice as much.
I always thought they were a good idea because they put the hot water into the top of the tank and heat the tank downwards. They also did the solarsyphon.
