HOLIDAY SEASON AND UNDERFLOOR HEATING.

 

We’ve had a mini holiday too and set off to visit the Grandparents at a lovely little holiday cottage near Loch Morlich with multiple trips to the Nairn and Loch Morlich beaches for sand obsessed Rosie. It was great to get away from the building site for a bit and spend some family time together.

In the meantime we have had some good progress in other areas. Our slate roof is complete and we finally have a wind and watertight house with loads of insulation. Our dormer windows have been clad with log profile timber and we have an electricity connection!

Our windows also have some lovely new framing. It’s looking beautiful and it’s great to see the exterior nearing completion. All that’s left is the frames on the big glass wall, guttering and doors. I’ve been giving the windows their first coat of Osmo UV protection oil today. It’s pretty much non stop painting here at the moment!

We have also had a visit from fantastic local heating company Black Isle Renewables who came by to install the pipes and manifold for our underfloor heating system. As a family who have lived in a caravan for six years with only a wood burning stove to keep it cosy, a central heating system was definitely one of the most important things to consider when building a house. Black Isle Renewables have been fantastic at offering advice and options and designing a heating system that works with our house and will keep us toasty all winter long.

We have chosen an air source heat pump to supply us with hot water and power the underfloor heating. The air source heat pump works kind of like a fridge in reverse. It extracts energy from the air outside the house and the heat from the air is absorbed by a fluid which is pumped through a heat exchanger. This fluid passes through a compressor, and is concentrated into a higher temperature, capable of heating water for the underfloor heating and hot water circuits of the house. The pump can extract heat from the air even when the outside temperature is below freezing so it should work really efficiently  even in the depths of a Highland winter.

The heat pump won’t get installed for quite a few weeks but the pipes have to be in place so the floor can be built on top. The pipes are then covered with a dry screed mixture of sand and concrete which protects them and helps distribute the heat. This is then sealed under a chipboard floor and then eventually a lovely engineered oak floor.

Below is a super nerdy video for anyone interested. It was really satisfying to watch the underfloor heating pipes being filled and tested. The liquid is a mixture of antifreeze and water and is coloured green so you can make sure there are no air bubbles.

This week our window framing will be finished off and I heard a rumour that the front and back door might be going in! As for me, I’ll be doing more painting and collecting a beautiful specially made slate hearth for our wood burning stove.
