On Monday, 28th January (Day 19), a new team of workers began with the installation of the ventilation system, and with the further insulation of the roof. In modern houses built here in the North, air does not get exchanged by periodically opening all windows or some such. Also, the houses are built nearly completely air tight, and therefore ventilation must be enforced. This happens through a series of large pipes installed above the ceiling under the roof. Modern ventilation systems include heat exchangers, which use the outflowing warm air to pre-heat the fresh air from outside and thereby conserving energy.
all that hose pipe on the floor, which forms the floor heating. The photo above shows the distribution point from which hoses branch out into every room, and also the return flow is coming back together here. Controlling everything is a series of valves, one for each room, which are remote-controlled from thermostats in the rooms. The ball of electrical cabling is visible behind the folio, and so are red and blue valves for warm outflow and cooler return flow, respectively.
The next step is to fill the entire floor area with very liquid concrete to make a smooth, even surface, which will eventually be covered by the flooring.
A lot has happened in the past week, but due to time constraints, blogging daily was not possible. Normal service will resume this week – we hope.
