GSHP have, over the last decade, declined in popularity because of the higher initial cost for only a tiny performance improvement. We also tend to have small gardens in the UK, do borehole drilling is best for most people. The UK has very mixed geology and drilling easily in one place may become really hard just a few miles away. Even down here in Cornwall, with some of the best understood geology in the world, and a £1m to play with, the Jubilee Pool project went disastrously wrong.

So do we. They you would waste less time on here trying to become a Mod.

Or part of the true cost of having pets. https://www.amazon.co.uk/Time-Eat-Dog-Sustainable-Living/dp/0500287902

We have a similar thing here, just the rates are different. There is often schemes set up to trade home grown, last I saw was a Blockchain system. Non last long as energy is way too cheap.

Like Dash Cam, home security cameras will also pick up your own bad behaviour. Today, while enjoying a coffee, the shopping centre security man went to the lavatory. I noticed he had a Vest Cam. Hope he turned it off.

How is that done then?

Not as simple as that. Ideally you would need to add extra insulation, which is hard after a building is sitting on it.

Welcome. Have you checked for leaks/cracks on the outside? Downpipe and gutter problems as well. Also is it possible the roof has failed and water is getting in there, then finding a path to the wall. What construction type is your building?

Yes, those ones may well be, they were less than a quid each. They work OK.

Here is the code I use. Just change the 28-xxxxxxxxxxxx number to your sensors number. You can add more sensors by just copying and pasting in the part relating to the sensor while incrementing the number by one. Then add the sensor number to the "writes to data file" line. #!/usr/bin/python #imports necessary libaries import os, time, datetime #load drivers os.system('modprobe w1-gpio') os.system('modprobe w1-therm') while True: #Sort out the time format dt = datetime.datetime.now() runday = dt.day dt.day == runday #sensor 1 tfile = open("/sys/bus/w1/devices/28-0306979462ca/w1_slave") text1 = tfile.read() tfile.close() temperature_data1 = text1.split()[-1] temperature1 = float(temperature_data1[2:]) temperature1 = temperature1 / 1000 #sensor 2 tfile = open("/sys/bus/w1/devices/28-031097946bbc/w1_slave") text2 = tfile.read() tfile.close() temperature_data2 = text2.split()[-1] temperature2 = float(temperature_data2[2:]) temperature2 = temperature2 / 1000 #sensor 3 tfile = open("/sys/bus/w1/devices/28-030197941c13/w1_slave") text3 = tfile.read() tfile.close() temperature_data3 = text3.split()[-1] temperature3 = float(temperature_data3[2:]) temperature3 = temperature3 / 1000 #sensor 4 # tfile = open("/sys/bus/w1/devices/28-03149794263a/w1_slave") # text4 = tfile.read() # tfile.close() # temperature_data4 = text4.split()[-1] # temperature4 = float(temperature_data4[2:]) # temperature4 = temperature4 / 1000 #opens and reads the time ts = time.time() #sets time to UTC and dd/mm/yyyy hh:mm:ss format UTC = datetime.datetime.utcfromtimestamp(ts).strftime('%d/%m/%Y %H:%M:%S') logfile = '/home/pi/monitoring/data/1wire-%s-%s-%s.csv' % (dt.day, dt.month, dt.year) #creates and opens or appends data to file tfile = open(logfile, "a") #writes to data file tfile.write("%s"%UTC + ",%s"%temperature1 + ",%s"%temperature2 + ",%s"%temperature3 + '\n') #closes data file tfile.close #sleeps for (n) seconds until next reading time.sleep(25)

From my comic a few weeks back. HOME HEATING Many uses for hydrogen are mooted, but some are far from guaranteed to materialise. One is decarbonising home heating, with proponents arguing that countries, including the UK, could repurpose existing gas pipe networks to carry hydrogen and swap natural gas boilers for ones capable of burning hydrogen. Leeds in the UK has been mooted as an early candidate for switching entirely to hydrogen instead of natural gas for heating and cooking, with a 2016 report by the local energy network finding the idea “technically possible and economically viable”. In November, the UK government said it would support a village-scale hydrogen heating trial by 2025. Sceptics say it would be more efficient to use renewable electricity directly with heat pumps to warm homes, rather than losing energy by converting it to hydrogen first. A recent report by Jan Rosenow and a team at the UK Energy Research Centre concluded that there is so much uncertainty about hydrogen’s role in decarbonising heat that other options should be the UK’s priority in the next decade. These include networks that pipe heat to many homes from a large, central source such as an industrial plant, energy efficiency improvements and heat pumps.

Wow, a piece if kit you can't get fuel for. Unless you want to pay £10/kg for it.

Or Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over. or

Yes, fit the 3P now. You will loose a bigger difference in timber offcuts and dropped screws during the build. And if you like making things in a workshop, 3P machines are cheaper.

Made a little one earlier.

So nothing really changed then, so what did you use in the old place? You could replace some radiators with skirting radiators.

Probably not going to happen, it is very mature technology. You should be doing that anyway, but think of it as energy usage, rather than gas usage.

Do you know how much hot water you currently use? It is not hard to measure it.

Will you be trying to improve the airtightness at the same time? Depending on house layout and heat load, have a look at Air to Air Heat Pumps. What are you doing about DHW heating i.e. stored HW or instantaneous (like a combi).

These are the two, Jim and Barry, that blew me away in the 1970's

Hope they shave

Are these your invisible friends.

I don't see why not if the compression strength is enough. A quick interweb search throws up 0.5 MPa for Foamglas. Brick seems to be between 0.28 and 2.8 MPa. There is more to it than just compressive strength. Thermal expansion and failure modes spring to mind. I do like the idea of making a house out of it because the thermal properties are so good. 0.038 to 0.055 W/m.K for foam glass, and 0.15 to 1.6 W/m.K for brick.

That is an interesting question. I think someone, over at the other place, looked into the marginal embodied energy and CO2 differences between insulation types, and seem to remember that someone on here did something similar between wall types. You can get decent raw data from Bath Universities' ICE database.
