There wouldn't be any run off if you get it just right. You might end up with hard water scale all over your roof though! What about using the water in the butt with a pump? Run off doesn't matter then, it just goes round and round. Might end up with a steaming hot water butt thought ;-)

Or run the pipe, very long lengths of it, underground (while underground install 4" drain pipes to hold more water) and the temp will be the same as the mains water coming in.
Or run this pipe under your concrete floor, or under a 1st floor suspended floor, and cool that way. All for free, except running a pump.

just been saunad in my loft I am considering lo-tech solutions.

This is what the market traders in Prague do with their stalls. It did just seem to make puddles on the floor but I guess it must work otherwise they wouldn't do it?

Alot of pergola's here in Australia have this 'feature' and in the summer everyone tries to get under the bit with the most water coming out - it never makes it to the end of the run.
Works well

Difficult to resist a small gloat as I sit in my 'home office' with the air conditioner whispering the temperature down to a comfortable 22 degrees when the OAT according to the thermometer in the car is 34 degrees ... Yes, it cost a bit to have it installed, but through last winter it acted as a localised heater therefore not requiring the gas boiler on heating the whole house, and over the last few months has provided very efficient cooling, significantly enhancing productivity (if you disregard the time spent on mailing News groups gloating ... ) :) :) :)

I think the subject has already been done to death in the past Jim, but in a nutshell, the office - like many others have - is an 'extra room' on the end of the garage, about 11'x7' (always intended as 'workspace' right from the Architect's design stage) and I am very happy with a split a/c system (rated at about 2.7Kw ?) installed last year. In previous threads the general consensus seemed to be that evaporative coolers are a waste of space, portable units are not very effective, but are better than nothing, but a 'proper' permanent installation is the way to go. Others suggested that improved insulation, use of appropriate vegetation and other 'natural' measures were a preferable and lower cost alternative.
A DIY alternative to a specialist-installed system is available to suit a 'spare bedroom office' if you have a bit of free space available against an outside wall. It requires no "plumbing", purging, charging with refrigerant etc., merely a hole through the wall similar to that required for a tumble dryer for the warm air exhaust, then all the other gubbins is contained in one ready-to-go unit that is fitted on the wall inside.
Most owners of cars with automatic transmission would not go back to manual; most owners of cars fitted with air conditioning would not go back to one without. As for me, I now wonder how I ever managed over the last 9 years without a/c in the 'office' ...

I was in a building that was highly insulated with the windows with roof overhangs that shaded them from the sun. Windows were open to give through ventilation and few desk fans were on. The temperature was very comfortable as insulation keeps heat out as well as in.
Comncemrtrate on the fabric of the building and through ventilation. The last thing I want in hot weather is to sit in 20C inside. As the outside temp rises you acclimatise and can take higher indoor temps.

Course what the International Man of Muddle often forgets is the sodding humidity and that theres a heat gain from the equipment you need to have in the room Hence that's why I've got aircon and on a day like today I can actually work in the place.
Course when its 30 odd outside the fans that blow the air round that comes in through the windows manage to get that and the humidity down, don't they?.....

No machines with large heat outputs were around. Laptops and the likes. Lights were localised on desks. A heavy printer was in a separate room.

Humidity was not a problem.

21C!! In this weather that is cold. Laws should be introduced to stop people installing this crap in domestic homes. All is does is increase global warming. Go and get your building fabric sorted out: insulation, shading, ventilation with air drawn from the north side, air extracted at ceiling level to eliminate the hot pool of heat created by the thermals mass of the ceiling, loft fans to draw in cool overnight air cooling the loft ready for it to absorb the heat of the following day and draw out excessive daytime heat, etc. Look at how hot countries do it naturally..
A/C in the UK!! Madness!!

Well in this instance I'll agree with IMM! 21c is really cool. However as long as the RH is OK then I don't mind it being hotter..

So how do you get the humidity down to a tolerable level?..

It certainly is. 20 is even more cool.

Whereas I do.
I quite believe you don't mind it being hotter. The fact remains that I do and I always have. The only time I don't mind it being hotter is when swimming.

So you dress for the climate, as they do in hot countries. Sitting in a room of 21C with a full three piece suit on is silly.
