During the oil crisis of the 1970s, it became common to install electric heating in smaller detached houses and residences. The first generation of electric radiators used a bimetal thermostat, which controlled the heat very irregularly, with a hysteresis of up to 6 degrees. Today, there is a new generation of oil-filled electric radiators on the market. According to studies conducted by LVI with independent partners, you can save up to 20% on energy costs by switching from old electric heating radiators to modern electric radiators with electronic thermostats. The accuracy of an LVI Yali Digital oil-filled electric radiator with an electronic thermostat is better than +/- 0.15 degrees. In today's buildings, with proper insulation, electric heating is a smart choice. This is because the energy requirement per square metre has decreased drastically over the past few decades. Direct electric heating produces heat directly in a room and is directly connected to the main power. This makes its installation very affordable. And, electric radiators do not lose any heat into the ground, which is always the case with, for example, underfloor heating.
Oil-filled radiators can be set at a lower surface temperature, which prevents the air from becoming dry and dust from circulating. In addition to this, oil-filled electric radiators do not emit any unpleasant odours. Lowering the temperature a few degrees during the night will allow you to save a lot of energy. As a rule, every degree you lower the indoor temperature below 21 degrees will save you 5 per cent on your electricity costs. Modern radiators with electronic controls can be set for automatic reduction (night).
It is not uncommon for energy-efficient houses to have problems with downdrafts and floor drafts. However, the proper use of energy will provide both a low energy consumption and a high level of comfort. Recent findings show that the installation of small electric radiators can provide a high level of comfort in passive houses, without increasing energy consumption.
Air heating from heating cartridges in conventional passive houses is insufficient for preventing downdrafts from downward airflows, which form even when triple-glazed windows are installed. However, convection from wall-mounted, oil-filled electric radiators, with their upflow of heat, augments the distribution of heat in a room.
Oil-filled radiators, with a low output of 200-300 W, act as an excellent supplementary heating source in passive houses. Smaller heating sources in the form of radiators provide a more uniformly distributed temperature, both through radiation and convection. Through convection, radiator heat provides an upward flow of heat, which quickly distributes the heat to every corner of the room.
Passive houses are actually houses that are air heated by heating cartridges, which is why, from a strictly physical-building standpoint, they do not always function as desired. When electric radiators come on, the floor temperature is improved. The residents appreciate having the ability to set different temperatures in different rooms, which is not possible with air heating.
Most second homes are heated with direct electric heating. Older radiators, which alternate between being very hot or cold, most likely have a bimetal thermostat. If you want to have a more even temperature and the possibility of saving up to 20% on energy costs, you should replace these radiators with modern oil-filled electric radiators.
With the new Touch E3 control system from LVI, you can easily control Yali Digital, Parada and Ramo radiators. Touch E3 helps reduce heating costs by simply controlling the heat in your home. You can, for example, maintain a lower indoor temperature when you are away and come home to the perfect temperature. Another feature of Touch E3 allows you to see your energy consumption in each room/zone. With the CleverTouch app, you can increase and decrease the indoor temperature from your smartphone.
Heating a house accounts for approximately 80% to 90% of the house's energy consumption. There are several ways to lower heating costs in a second home. The simplest way to reduce costs is to add extra insulation and seal the doors and windows.
In order to prevent moisture and frost damage during the winter, the radiators should maintain a temperature of approximately 10 degrees. Most of LVI's electric radiators come with a separate frost guard setting. This helps keep the temperature at around 7 degrees. Each degree of heat is equal to roughly 1,000 kWh. An air-source heat pump can also be an excellent complement during the winter.
