New Book "Build It"

[surreyarborist]

I have been givern a book by one of my clients (how kind)

 

DIY projects for Farmers, Smallholders and Gardeners.

 

There are over 50 projects to make and i like the way in layman terms Joe Jacobs describes how to go about it and the sciece behind the projects, ie the methane digester (not for the faint hearted)

but the chapter that got me really interested was "Installing a ground source heat pump" anyone with a digger will be making good money out of this one.

trench required min is 1.25m deep 1.25m wide and 30m to put the "Slinky" pipe in.

If you Google Kensa engineering they have a website which explains it in far more detail

The heat pump comes the size of a fridge and apparently for each unit of leccy you put into it running the pumps you get 4 units of heat

i surpose its like have a 4 bar heater on and only paying for 1.

With a log burner as well i reckon its the way forward.

I have no connection at all with the above company or the guy who wrote the book.

Btw its the ground which cools the refrigiant fluid into a liquid ready to be compressed into a gas in the heat pump unit which gets hot when it is compressed into a gas.

the ground source heat is really good

the farmer who built his house in a barn reconds he pays something ridiculously low (can't remember exact figure) as he has such a large system

the only expensive part is the industrial heat exchanger
