17.03.2026 Air-air heat pump Pt.2

 ~?~  

 Tuesday 17th 36F/2.2C [6.45] Light overcast with a tobacco filter in the east. 66F/19C in the room. 57F/14C in the greenhouse.

 Up at 4am. Wide awake. No visit to my friend today. 

 Watching videos on heat pumps. Moving furniture to make room for low level and floor standing indoor units. My original idea avoided sitting in "the wind" but directed the heat to the open stairwell. That would leave the main sitting area in the cold. 

 While a low level unit could blow warm air along the floor from the wall near the TV. Towards the computer desk, TV chair and the bed. Where it would rise by convection to form and circular air flow.

 A long time owner of a heat pump said that high level units struggle to match the heat required. Due to stratification. While his low mounted unit kept an entire upstairs room arrangement warm. Consisting of a living room, office, bedrooms and bathroom. Good to know.

 My original drawing is horribly out of scale. This end of the L-shaped room is far more roomy than it appears. So I have now redrawn the east wall to better match reality. Still not to scale!

 The outside heat pump unit coincides with where I keep the three, recycling, wheelie bins. Not a problem. Plenty of room. I have discovered that the heat pump's mains plug must be earthed. The nearest sockets indoors are close but not earthed. They date from a period where Denmark did not have earthed sockets and plugs. 

 However, the plastic water supply pipe lies close to this wall. The storm of '99 brought down a telegraph pole with TV aerials mounted. This broke the buried water pipe at its base and it had to be rejoined. So hammering an earth rod in just there might be risky. I might have to dig down to expose the pipe's exact position. An earth rod would be far simpler and probably cheaper than indoor rewiring back to the consumer unit. Which in on the other side of the house.

 9.30 Sunshine. I drove into the village to shop. Having run out of essentials. I'll ride in again later. When the pharmacy is open.

 12.00 Back from the chemist. I have to have an annual checkup at the doctors. Twice, next month. MOT and service. 

 Dinner was chicken, mushrooms, tomatoes and chips.
