Week89 - 23Jun 2003

Progress this week

This week with the main bedroom complete, I set to work on digging the trenches for the Heat Pump. In case you have forgotten, the heat pump works like this:

The system is widely used in Sweden (where mine was manufactured) and through much of Europe and the USA. It is 350% efficient i.e. for every KW of electricity used to pump the water, compress the refrigerant etc - it produces 3.5KW of heat.

This week I start digging the trenches.........

I start digging with a 1.5ton digger...
progress is reasonable but I realise a bigger digger would be much better
so I call my frindly Plant Hire company and upgrade to a 3.5 ton version
progress is then much better.
The biggest problem is managing the volume of soil
