Energy Crisis: why heat pumps with home energy package?


Let’s imagine you’re a homeowner in 2022. You might live in England, France, or any other European country, for that matter, and you’re concerned about the potential energy crisis. Not only have energy costs become volatile but your purchasing power has also been hit by inflation. In addition, you have concerns about climate change and the environment. But what if there was a heating solution that could enable you to become less reliant on fossil fuels, save money, AND be more eco-conscious? This type of solution would soften the impact of unreliable energy prices, keep you in compliance with new environmental laws, and give you complete control over your energy consumption. Let’s take a look at this very solution together.

Heat Pumps: for 1kWh of electricity, get around 4 times the heat!

Maybe you’ve never heard of heat pumps before, or maybe just a few times but you’re hesitant to invest in them because of their high initial costs. However, they might represent your best heating option for riding out the upcoming years of growing energy insecurity, and here’s why.


1) Heat pumps are a smart financial move

Since you might be skeptical about heat pumps because of the required upfront investment, let’s take a look at them from financial standpoint. In many European countries, government funding opportunities such as the Boiler Upgrade Scheme (BUS) in the UK or MaPrimeRenov in France exist in order to lessen the economic burden of heat pump installation2). Not only that, but with the recent surge in energy prices, heat pumps have the primary advantage of being reliable and cost-efficient. They even pay for themselves in the long run because they consume less electricity. Your energy bills will be lower, which means you won’t depend as much as your neighbor on fossil fuels3). An explanation, you say?


2) Heat pumps are super energy-efficient solutions

Heat pumps produce up to 4 units of heat per unit of electrical energy consumed1), which makes them one of the most energy-efficient heating solutions available on the market. Higher efficiency translates to lower costs. Are you wondering how this is even possible? Heat pumps extract heat from the surrounding ground or air, then transfer that heat indoors. Meaning that they don’t produce heat directly but rather relocate it. 


3) Heat pumps are eco-conscious heating solutions

The secret to heat pumps’ efficiency lies in their energy source: 75% of their energy comes from their surrounding environment while the remaining 25% is supplied by electricity1). That’s also why heat pumps are referred to as “low-carbon” or a “way to decarbonize your home” and are a preferred HVAC design for nearly zero-energy houses. Let’s take a closer look at heat pumps as an eco-conscious heating solution. In this chart, you’ll notice that heat pumps emit the least amount of CO2 among the most popular heat energy sources. In particular, when a heat pump is powered by renewable energy such as solar or wind energy, its annual CO2 emissions approach zero.

Heat pumps, solar panels, and ESS: the ultimate zero-emission strategy

The performance of heat pumps may have convinced you, but you’ll notice that 25% of energy is still coming from electricity, meaning you’re only 75% self-sufficient. To achieve complete energy self-reliance and zero-emission heating, you should definitely consider combining heat pumps with solar panels and ESS. Let’s examine why. 


1) Solar energy is the cheapest and most used renewable energy

To begin with, you might wonder why you should choose solar energy. Solar energy is cost-effective. It’s not only the cheapest renewable energy*, but also one of the most commonly used. From a more practical standpoint, solar panels are flat with no moving parts, which makes them silent, discreet, and easy to maintain. Furthermore, solar panels are built to withstand extreme weather conditions. They’re reliable and long-lasting. Electricity loss is also prevented thanks to the proximity to the energy source.

2) ESS is key to managing your solar energy and heat pump combination

Unfortunately, solar panels have an obvious limitation. Solar panels rely on the sun to produce energy. In other words, the energy you’re producing during the daytime needs to be stored in order to use it when needed. That’s where ESS (Energy Storage System) products come into play. With ESS, you can safely store electricity for future use. In addition to safe storage, ESS also functions as emergency power in the event of a blackout and optimizes your energy consumption by using stored energy according to peak hours. This means that you’ll be protected from blackouts and energy price surges from the main electricity grid thanks to the energy stored from the daylight. Not convinced yet? Recent improvements in battery cell technology and dropping ESS prices make it the perfect time for you to become energy self-reliant. 


In particular, combining your solar panels with the LG THERMA V air source heat pump and an LG ESS enables you to maximize your savings thanks to a smarter and greener operation system. Sure, an ESS can store energy, but what about the surplus energy that can’t be stored? LG ESS has a strategy for that. When the ESS is fully charged, a signal is sent to the heat pump and the excess electricity is used to heat the water or buffer tank. This accumulated heat works as heat storage. Therefore, because LG ESS communicates with the LG air source heat pump, your surplus electricity is automatically used to increase the set temperature of your heat pump as well as that of your water tank so that the heat can be stored. On the other hand, when the available energy is low, LG ESS communicates with the LG air source heat pump to lower its set temperature or even to turn it off completely. This strategy to either save energy when the energy storage is low or store the heat when there is excess energy sets LG ESS apart from other products.

3) Energy production and consumption monitoring through LG ThinQ

We previously mentioned how heat pumps automatically adjust their set temperature according to signals sent from the ESS. However, even though ESS and heat pumps work in accord, you should be able to monitor your energy use as you wish. Therefore, LG created the LG ThinQ app to meet this specific need. It enables you to monitor, control, and manage your energy, wherever and whenever. The stored energy levels and operation modes of the heat pump, energy levels and charging status of the ESS, and more can all be verified in real-time. This app also connects with any other LG smart home appliance you might already have so that you can manage everything in one place. Besides, if you have any issues, the app allows for quick and simple system connectivity for your peace of mind.
