A chiller is basically what a dehumidifier is hence why its got a condensate drain. In larger installations the amount of dehumidification is controlled to suit the type of produce being stored as if excessive moisture is removed you get dessication/ drying of the produce etc - normally its...
I'd try the cotton wool and superglue trick Take the plugs out and pack the holes right with cotton wool and then apply superglue to the cotton wool, the thin type not the gel. It will react quickly and form a solid mass. It gets hot and may well give off fumes. Avoid breathing these! When...
I've had a festool midi one for years the plastic bit for the hose cracked and so did the plug connection plate where you connect power tools. I gave a loan of it to someone a few years back and it was returned with a knackered speed control knob due to ham fisted borrower I think more than an...
Normally when making up patterns shrinkage has to be accounted for as metal cools. If the frame is circa 6 foot long then shrinkage would need to be factored in.
I work with some architects in Edinburgh that do a fair bit of work in refurbishment of old buildings in Edinburgh such as Drummond Place, Atholl crescent and Melville St etc. I can ask them where they source such items if you want. I seem to remember new cast iron parts being sourced for...
I'm slowly getting the house insulated enough for ground source as I'm on oil but no point financially at the moment with the likely hikes in electricity costs coming our way.
Even if I installed a GSHP with a pretty decent COP of say 4 or there about, it would still cost more to run than the...
I would stick with the biomass short term and concentrate on insulating the place.
Its worth doing heat loss calcs to see what size heat pump you need. Ideally if you can do the heat losses to BS EN 12831 as that's what the MCS installers have to base the sizing on. If you can and intend to...
The ground won't freeze unless someone makes an buttocks of sizing the boreholes. Freezing ground is a result of trying to extract too much heat out of the bores.
Wet area with high water table is good as any water movement near the boreholes will improve heat transfer
