Footings almost all dug now

View attachment 843714View attachment 843715

You can see how they are stepped down so they are on firm ground

2ft 6 " on bed rock are they?

 

[Speedstar]

Any reason for more than just ground source for heating and water ?

No I think that and solar thermal is all we need, don't like open fires and no need for a back up boiler

Some of the footings have 450mm of concrete in them on to rock so it is not going to move

 

[Speedstar]

All concrete in the footings is now all

Do you use Local Authority Building control or private Building inspector there in Scotland?

Just asking as I was speaking to a company down our way and he was telling me about people using both . I thought the ground source would be more than enough in a new build house ?

Yes in a new build with all that insulation it should not take a lot to heat it, ask me again a few years time for the answer as i am unsure about all this but going by the ones we have looked at it works great, just need some better weather to get it wind & water tight before winter is here for real

How many meters of pipe are you digging in ? Or is it borehole ?

in total about 350 meters of pipe in the ground in 1 meter deep runs , all laid in straight lines , hope to have start with this in the next couple of weeks, a good bit of work for the digger

A nice 4ft wide bucket and you'll get the pipe up one side and back down the other from what I was told ?

It’s how we did ours, 4 foot bucket on a CAT 312, digging in some clay and then sand and gravel the trenches were a bit wider anyhow which was a good thing. Dug all the trenches before lunchtime on first day and used the sand to bed and cover the pipes. The lads laying the pipes would not believe us that we were ready for pipes! They were used to three tonners on projects!!!

do ground source heating pipes need to be put in level? or can they follow ground contours?

Check with the GSHP guy before you install the pipework - I know of one that had to be extended because they put them in on a bed of sand - they need decent heat conduction, so should have been on wet soil/ clay or the likes. The sand acted as an insulator and reduced the effectiveness of the ground loop. Think I'd be adding a good dollop of well rotted dung if it was me!

That’s interesting as ours were covered with sand as you would with water pipes to get a 100% cover and to protect the pipes from stones and gravel etc in the spoil. We would of had to buy in sand according to the suppliers and installers but fortunately hit enough as we dug. We knew there was sand and gravel here as there’s a quarry just over the road and another two or three mikes away!!

Ours actually go uphill to follow the field, if I knew what I know now I would of actually send the insulated pair of pipes across the yard and gone down another field right through a very wet patch covered in rushes!!

If you have a pond or stream available they can be used instead of a field normally with far less piping.

I'm guessing a slow running stream ?

Would think faster would be better - if you can get more water flowing, there’s more heat to extract without freezing anything. Best would be a big loch that catches a lot of sun.
