ASHP and micro-harvests

When it comes to plumbing, electrics and heating in the home it may all be in Mandarin for the level of understanding I have. Husband makes it sound very logical and simple, and clearly finds it amusing that I either panic or glaze over when he tries to explain how electrical things work.

Yesterday we had the plumbers in to install the Air Source Heat Pump system for the house. This is a core element in heating the house as economically as possible, something that is becoming increasingly essential.

We now have a plant room with hot water tank, expansion vessels, underfloor heating pipes and outside, mounted on a concrete slab, the ASHP unit.

To me the assemblage in the plant room looks like something out of a gothic horror novel, all those pipes and valves and control panels. A local friend described it as looking like “a steam train mated with a brass band” which made me laugh out loud.

The electrician needs to come next week to complete the installation before we can crank it up and start testing it.

But it’s progress! Once it’s in and working we can lay the rest of the flooring, which will be another major milestone.

Whilst the install operation was underway I hid in the Polycrub.

There’s always something happening in there at this point in the growing year and the tomatoes and squash are now so large that I can hide amongst them quite effectively.

Every morning when I open up the tunnel to water the plants I pick as I go, a sort of micro-harvest. A few ripe strawberries, a handful of peas, a few bunches of coriander, dill , parsley, some lettuce. It doesn’t seem like much, but soon it will mean that we won’t have to buy those things.

Once the freezer and dehydrator are up and running, we’ll be able to store surpluses. At the moment we share any excess with our friends and neighbours.

It’s like receiving a gift every day.

It’s so satisfying to feel that you’ve grown this yourself, and that it will be on the table by supper time. Small steps towards self sufficiency.

Cold, starry nights, and concrete

As we move through November we draw ever closer to the winter solstice and the darkest, longest night of the year. The constellations of Orion and the Plough are clear and bright in the dark night skies, and we start to sense the breath of winter across the croft.

Starry skies

It’s time for warming stews, winter berries, warm spices and the comfort of thick socks and jumpers in the caravan. The fire is on most of the time now.

And time for concrete. After months of let downs, delays, finding new solutions and a new supplier, we at last have a firm date for the arrival of the liquid thermal screed to go over our underfloor heating pipes in the house to make our floor.

Pouring thermal screed

It’s coming next week. It’s taken us a whole year to get to this stage and this is a big milestone for us. Once the floor is hard and dry enough to walk on, some weeks down the line, husband will start the MVHR duct installation and electrical wiring in preparation for plasterboard installation early in the new year.

I try not to wish my life away by focussing upon this time next year when we will be dry and cosy in the house. I’m conscious that although it’s what I want, that every day is precious, and that it’s still a long journey to get to that point.

We may be in a cold and drafty caravan which causes a sharp intake of breath before getting dressed in the mornings (with as many layers as we can) or a leap into the shower squeaking at the exposure of skin to cold air before the hot water hits, but this way of life also has its blessings.

We are very aware of, and very close to nature and the elements. The night skies are remarkable at this time of the year. The storms are elemental. This year has been one of reconnection with the land and weather after many years of numbness caused by urban living, and it’s been remarkable.

Opening the caravan door and listening to the rushing of the burn over the croft on a crisp, starry night, perhaps with the occasional hoot of an owl is a wonderful experience. There are no other sounds. The silence is profound.

When the storms hit and we are tucked up under warm quilts or blankets listening to the wind tearing across the croft, or the rain lashing the windows, it does also instill a very real sense of well-being and cosiness. We are grateful that we’re not out there in the teeth of the storm like so many have to be, and very aware of its power.

We count ourselves as very blessed.

Life is good.

We have underfloor heating pipes…

Things are progressing slowly but steadily now. We now have a flooring membrane throughout the house laid over the insulation sheets and edged with foam strip to allow for the screed expansion.

Exciting times, although the smell of the plastic was overwhelming for a bit!

We had originally thought to use a grid to lay the pipes onto, but as we’re tight for depth to the window base, husband decided to lay them free-form to save a few millimetres extra for the screed.

The cryptic markings which appeared mysteriously overnight apparently direct the traffic for the underfloor pipe layout.

These will be laid throughout the ground floor with the exception of the small room that we plan to use as a pantry, which we want to keep as cool as possible.

With a bit of luck we should be ready for the screed in the next few weeks.
