Heat Pump Installation

My most vivid memory standing out on that day full of disruption and commotion which also was the second day of the new lockdown was The Calm One trying to find his mask before he sprinted down the hallway leading to the bathroom from which one of the two workers, both Moldavians who live in Paris, the epicentre of the Pandemic, had cried out while handling a major leak from an ancient toilet tank fastened high up on the wall caused by certain pipes just removed in the sous-sol. Before The Calm One could locate his mask, the installer called out again, and The Calm One flashed out of sight. Soooooooo, there were two unmasked people, strangers to each other, in a small, unventilated space. I cracked open the bathroom door and dangled the city-issued blue jobbie inside, robotically uttering mask, mask, mask, mask, mask, until it was grabbed. In three days time, fourteen days, the recommended time for quarantine if one suspects exposure, will have lapsed. Despite not having any covid symptoms as of yet, our oximeter is never that far away. The workers arrived masked, but soon discarded them. They mostly worked in ventilated spaces like outside and the sous-sol with its front and back doors opened, but still. The two men did a fabulous job in about eight hours. When first staring at the tangled mess of dusty pipes covered in ghostly, insulation strips dangling from our thirty-five-year old gas system that was in place when we moved here ten years ago, a long, tortured series of ooh la las came from the installers. They agreed not to place the outside unit on the side of the house closest to a neighbour as was originally planned because it makes a noise like a loud fan along with the air getting pretty blown about from time to time. However, the change in plans meant more work for them because they had to drill through two rooms to get to the side farthest away from other houses.

The jumbled mass of pipes/valves were replaced. The old boiler and water heater were removed. We were told that our old gas system was way more powerful than needed, spewing out more gunk than was even necessary because all those decades ago gas was cheap.


The spanking new HUGE water heater was put in a corner.


To the left of that went an evaporator, and to left of that . . .


. . . a compressor that is connected to . . .


. . . to the outdoor double fan condenser in the east garden, essentially a reverse refrigerator. A refrigerant runs throught all parts of this system. Our upstairs which is where we live (our home is a pavillon sur sous-sol, a common abode in France) is heated via the heat pump set-up through existing water radiators. This arrangement also heats the water for the kitchen and bathroom. Part of the deal was our getting an induction stovetop to replace our gas cooker which once installed will allow us to cancel our gas service.


A most lovely rosemary of the hedge type had to be hacked down to make room for the outside unit.


The mass of aromatic foliage will be composted eventually.


Fortunately about two months ago I took two rosemary cuttings which have rooted well. Our household will not be sans rosemary!


A very plain, straightforward thermostat was affixed to the centre hallway wall of our upstairs living quarters. My goodness, everything is so much more comfortable, very much like being in a luxury hotel providing tons of almost instant hot water with pronounced pressure along with a stable temperature in all rooms. I am glad that this government subsidised program approved us as participants; acceptance took about four steps spaced over several months. The part of the expense we need to pay is in the form of a loan with a moderate rate of interest which can be paid in full if we wish before the final scheduled payment. Our Total Conversion To Alternative Energy Project which now includes the completed installation of photovoltaic panels (no government subsidy, but an interest free loan) and the heat pump will continue with our getting a storage battery in due course. Following that, if required, we will get more photovoltaic panels.  Though our motivation for our grand project at present is to reduce our monthly utility bill, the eventual goal is not only to get off the grid but also to earn income by selling surplus energy back to the sector.


See you next week!
