Along with our new boiler, we also got a new thermostat – a Nest Learning Thermostat. I’d actually bought it in January, in the hope that it could be fitted to our existing 1970s central heating system. With both Christine and I being on maternity and paternity leave respectively, we were at home most of the day and so the heating was on almost constantly – I hoped that a better thermostat would cut the amount of energy required. Alas, the fitter who came to install it told us that our system was too old – he could fit it, but it would only power either the hot water or the heating, and not both at the same time.
Now that we have a more modern boiler, we could also make use of the new thermostat.
The previous thermostat also dated from the 1970s and was a basic model that, theoretically, would heat the house until it reached the set temperature and stop. But I’m convinced that it didn’t do the latter – the heating would still be on even when it was utterly roasting. With such an old system, the fault could have been in any one of several places. Either way, it’s not an issue now.
Whereas the old thermostat was upstairs, we’ve fitted the Nest in the dining room. You can install it using the standard thermostat cables to your boiler, or there’s a micro-USB socket and an AC adaptor included. We decided to go for the latter, in case we want to move it somewhere else. It’s quite easy to fit to the wall and the backplate even includes a spirit level to help you align it correctly.
The Nest offers several useful features:
- It learns how long your heating system takes to warm up. So if you want the house to be warm by 7:30am, you tell it that, rather than telling it to come on at 7am in the hope that your house will be warm enough by then.
- You can tell the thermostat that you are away, allowing it to maintain the house at a cooler temperature, thus saving energy.
- Your thermostat can be managed using official apps for smartphones or tablets, or on the web.
- It has a motion detector, so the display turns off when no-one is about. It can also turn your heating down if it detects no motion in the house for some time.
- Integration with IFTTT and other smart home technologies.
Whilst it’s been a warm couple of weeks, thanks to the Nest our heating has only needed to be on for an average of 30 minutes per day. I’m hoping that it will save on our energy bills – my mother-in-law has one, and she credits hers for halving her gas bill.
