Nest E vs Nest 3 Thermostat: A Handy Guide on Choosing Between the Two

nest-e-vs-nest-3Heating and cooling costs can be the most expensive utility in your household.

During winter months, heating costs tend to skyrocket forcing residents to either spend more on their utility bills, or sacrifice comfort for affordability by leaving the temperature at a more moderate setting. Smart thermostats can help with this challenge by saving you money and offering a level of convenience.

In this article, I’ll discuss the advantages of using a smart thermostat and the difference between the Nest E and Nest 3rd Generation.

But first…

What Makes a Smart Thermostat “Smart”?

The Nest Self Learning Thermostat is not only easy to install, it’s easy to operate. This is because it does all the work for you. All it requires is a quick setup, which most users can complete in less than thirty minutes (professional installation services are available if you prefer). Users just answer a few easy questions and Nest starts learning.

The system is automated, so you can set it to what temperature you want and what your schedule is. The thermostat adjusts for your particular type of system (forced air, dual pump, etc.) for optimal performance. As a bonus, the system learns when you’re away and automatically adjusts itself to save energy.

Nest personalizes its features for you. After it learns about you and your home, Nest Sense™ automatically balances comfort and energy savings. If you tell the system that your wake up time is 6 a.m., Nest will kick on and adjust to the temperature of your preference by that time.

Effortlessly Set Your Temperature From Anywhere

For your added convenience, the Nest system comes with built-in Wi-Fi for easy management from your phone, tablet, or PC. The advantage of any smart device is the internet connection which enables you the ability to change the temperature from anywhere.

Adjust your settings while you’re away, check your schedules, or view energy usage over a period of time. The easy to read interface makes comparing energy savings simple. As a bonus, Nest will also send you an email each month detailing your usage and how the changes are affecting your bottom line.

It is an energy management system that works for you. More than a standard thermostat, the Nest is as simple as plug it in, tell it what you want and let it start learning how to save you money. Lowering your thermostat a few degrees from your usual setting can translate into energy savings.

Attractive Design and Easy to Read

Visually the Nest is not only easy to use, but it is also attractive. Simple turns of a large convenient dial display make it easy to read with uncomplicated numbers on the display screen.

An icon of a leaf will appear when you’re saving money on energy to help guide you towards better habits. As you set your preferences over time, the system remembers and begins automatically adjusting to your needs.

Best of all…

The designs are sleek and unobtrusive. Both thermostats are aimed at saving you money but have a few distinct differences.

Let’s look at a side-by-side comparison of the two Nest thermostats.

Comparison of Nest Thermostat E and Nest 3rd Gen

central-nest-comparison-tableThe Nest thermostats are proven to save you money. According to two independent studies and a third study performed by Nest – from “real homes with real families and real thermostats,”

“On average the Nest Thermostat saved 10% to 12% on heating and 15% on cooling. Based on typical energy cost, we’ve estimated average savings of $131 to $145.”

The energy savings are expected from automatically adjusting the temperature when people are not home or sleeping at night.


Both thermostats, the Nest E and Nest 3rd Generation are designed to keep your home comfortable and save you money.

SWEP plans factory expansions

SWEDEN: Heat exchanger manufacturer, SWEP, has announced plans to expand its plants in Landskrona, Sweden, and Kosice, Slovakia, in order to meet increasing market demand in EMEA.

Construction work started in Landskrona at the end of November. New production equipment will be installed this summer, with all lines being optimised in the autumn. In addition to the production area 500m2 of new office space will also be built.

The 3,000m2 expansion in Kosice is planned to start early next year and is intended to be fully operational in the second half of 2022.

Commenting on the investment, SWEP’s general manager EMEA, Fredrik Paulsson, said:

“Renewable energy sources and more efficient energy use are absolute musts. SWEP’s heat exchanger technology plays a vital role in the conversion from old, non-sustainable sources and inefficient technologies. By expanding our production in EMEA through additional capacity equipment, such as press lines, furnaces and automation, we will significantly increase our abilities to serve the market. We are here to grow with our customers. With optimised operation flow, we become more flexible towards meeting demands, and thereby less vulnerable to unpredicted events.”

China urged to strengthen crackdown on CFC11 emissions

CHINA: Reported to be the source of a rise in emissions of banned CFC11, a crackdown by Chinese authorities is said to have located only three small illegal CFC11 production sites.

In 2018, the National Oceanic and Atmospheric Administration reported an unexpected rise in the banned ozone-depleting refrigerant and foam propellant CFC11. Fingers were pointed at China as the source. This was later supported by the Environmental Investigation Agency’s (EIA) report, Blowing It, which revealed evidence of the illegal use of CFC11 in China’s polyurethane foam sector.

Clare Perry, EIA’s climate campaigns leader applauded China’s ongoing enforcement efforts and that the latest atmospheric data indicates emissions were starting to come down as a result, but added: “There remain significant uncertainties in what has actually happened and the effectiveness of the enforcement actions so far.

“China has located only three illegal CFC11 production sites, with relatively small capacities which could not account for the level of illegal CFC11 production estimated by the Montreal Protocol’s technology experts (40,000-70,000 tonnes per year).

Perry was reacting to a report in Nature magazine today, which looks at the potential delay to the ozone hole recovery caused by unexpected CFC11 emissions. The paper, Delay in recovery of the Antarctic ozone hole from unexpected CFC-11 emissions, by researchers at the UK’s University of Leeds, examines the potential damage done. According to the paper, the delay could be as little as a few years if immediate action to stop the emissions is successful – ranging to as much as 18 years if emissions continue unabated.

Although agreeing with the authors that the worse-case scenario of an 18-year delay in the recovery of the ozone layer was unlikely, Perry said: “On the other hand, the likelihood of immediate effective action to stop the illegal emissions resulting in a delay of just a few years is a rather optimistic scenario.

“A fundamental problem is that we don’t know the actual CFC11 production level and the amount now contained in new foam materials – the “bank” – which ultimately will most likely leak to the atmosphere.”

The 2018 EIA report estimated this bank of CFC11 in the foam products created up to 2017 could be equivalent to almost four billion tonnes of CO2 (830,000 tonnes of CFC11).

“We are urging China to strengthen and enhance its enforcement efforts and undertake comprehensive testing of foams to better understand the situation,” added Perry.
