Let’s start by looking at a conventional heating system. You set the temperature, you decide the times to come on and off. Many people turn their heating off after bed time then on in the morning again. Maybe there is a holiday mode, a one or two week schedule to organise and summer winter time clock adjustment. With the possibility of more adjustment times the system may be capable of reducing excess use.
The reality…there are too many options, the menu’s confusing, it’s set once and left alone. Close enough will do because it may well be inefficient but most importantly it works.
You might feel shy to ask for help. Gas engineers are expensive. Setting a timer shouldn’t cost a call out fee but it does so it is left alone.
However most professionals fitting a conventional programmer/timer systems are not aware of all features. Reading the instructions is definitely required to make sense of it. If you can’t find the instructions, say when moving into a new home you have to look online for the right PDF to download. Then try to understand and implement.
Yes, It would be easier on an app.
Cold home after a holiday?
Have you ever returned home from holiday in winter to a cold house? Warming up the home takes much longer than normal. Why is that?
Because the fabric of the building is at ambient temperature after being left so long.
People create heat: breathing, moving, we expel energy. Remember house parties? How hot it can get in a crowded room!
After a long period of being off, turning the heating on costs more money. This is because the boiler is working harder to warm up more than just the air in the house but also the walls, furniture, insulation, carpet on the floor….everything in the heating zone.
What sensors are in a Nest Thermostat?
People affect the building’s temperature…the Nest will adjust for occupants before they even arrive.
Humidity can have drastic effects on heating. The Nest learning thermostat has a humidity sensor.
The sun light beaming through a window onto most conventional thermostats will give a false reading due to heat radiation. The Nest learning thermostat has a sunlight sensor.
Because the Google Nest Learning Thermostat is online it has access to more information such as the weather which it uses to create more accurate and effective heating.
Science behind the thermostat
The first law of thermodynamics is given as ΔU = Q − W, where ΔU is the change in internal energy of a system, Q is the net heat transfer (the sum of all heat transfer into and out of the system), and W is the net work done (the sum of all work done on or by the system).
The second law of thermodynamics states that the entropy of any isolated system always increases.
Thermodynamics is the study of the relations between heat, work, temperature, and energy. The laws of thermodynamics describe how the energy in a system changes and whether the system can perform useful work on its surroundings.
That doesn’t mean much to most people. Theres a third law too, but your Nest has worked it all out. Let’s explain why its relevant.
How does the Nest Thermostat do it?
After installation, the Google Nest Learning Thermostat will start….learning. It will learn how quickly the home heats up to target temperature and how long it takes cooling down to the eco temperature.
To save energy, the Nest Learning Thermostat will turn down the heating when there is no one at home. To stop the winter holiday super chill effect (as mentioned before) the Nest Learning Thermostat does not turn your heating off. It turns it down to eco mode.
This drastically changes things when it comes to warming up again. With an eco temperature holding the heat in the building a little, it means much faster warm up. Compensating for the weather, ascertaining the optimal time to turn on the heating as you approach home is calculated by the thermostat.
The actual function of geofencing, eco temperatures and money saving is all in the background. With your home cosy and at the temperature you like, it always remains the same from the occupant’s point of view. The home’s temperature is exactly the same when you go out as when you come home. Every time you go out, a previously missed saving has just been made.
One Thermodynamics algorithm you shouldn’t be without!
Remembering to turn your heating off before a holiday feels like a win. Once or twice a year, that’s great!
Remembering to turn down the heating and then turn it back up before you get home would need to be remote controlled and most importantly for it to realistically work, automated.
Do your part to be more green, save money, save the planet and make your home look good doing it!

What a thoroughly nice and decent guy. Had two thermostats installed and he did the job perfectly and was enthusiastic and helpful throughout. Really good value and a pleasure to do business with! Y Ekici19 November 2024Trustindex verifies that the original source of the review is Google. I cannot rate Mike more highly, 10 stars if I could. We have 3 nest thermometers over 3 floors with underfloor heating in the whole house but the pumps have been wired incorrectly (I think?!) so only 2 work, so instead of one thermometer heating each floor, one thermometer heats two floors and one doesn’t work. Mike came round and explained the problem, explained what we had to do to isolate the problem (turn off each of the 10 pipes individually to work out which heats which room) and then call him back to sort out the final re wiring if we need. This will take us about 14-16 hours because of how slowly underfloor heating works. If he wanted he easily could have said he’ll come round and do it and charge for that many hours. What a true professional and so so honest and helpful. We couldn’t believe it and it’s so rare to find. He didn’t even charge the full call out rate!!! Thank you so much Mike. Our wallet really REALLY appreciates your honesty. A. K22 October 2024Trustindex verifies that the original source of the review is Google. Fantastic experience from Mike end to end from his first initial call to his installation. Professional and friendly! B13 October 2024Trustindex verifies that the original source of the review is Google. Great, professional and fast service. Ellington McDonald5 October 2024Trustindex verifies that the original source of the review is Google. Mike resolved my issue with my Thermostat, without coming here or even charging me... there are still good people in this world 🌎 Don't give up hope 😊
