Week 4, Day 2:
- More progress removing soil from around the foundations, down to the level required for the concrete ‘oversite’.
- Connecting the GSHP collector pipes together at the manifold chamber.
- Digging a trench for the GSHP pipe tails to cross under the house and running them from the manifold to a location under the utility room.
Week 4, Day 2
32mm GSHP collector pipes connecting to the manifold enclosure which contains filling connectors and balancing valves. The upper collector pipes are the ones which run straight along the inside edge of each trench and carry the flow to the house; the lower ones are the slinky loops. All pipe joints outside the manifold chamber are made using electrofusion connectors.
