Ecombi > Off Peak Tariff



In the same way as the traditional storage heater, the ECOMBI system is designed to use the Time-Of-Use (TOU) or Time-Of-Day (TOD) low cost off-peak electricity.

How does Off Peak Electricity works

Most electricity providers offer heavily discounted rates for electricity consumed during off peak electricity times, giving you the chance to save money on your energy bill. Off peak electricity is provided during set times of the day when homes and businesses use a lot less electricity. Off peak times are typically between 11pm and 7am, but they can vary depending on the area.

What are Off Peak Electricity times?

Electricity providers would prefer to provide a steady supply of electricity throughout the day and night, because the turbines that generate electricity cannot be easily turned on and off as we need power in our homes. People generally use most of their electricity during the morning and evening. To encourage people to use electricity during other times of the day, many providers offer cheaper electricity during periods known as off peak electricity times. In homes, off peak electricity is commonly used to heat water and can also be used to power other heating appliances that are able to store heat when not in use.

How do you access Off Peak Electricity rates?

You have to contact to your local Electricity provider to get more details about Time-Of-Use (TOU) or Time-Of-Day (TOD) low cost Off Peak electricity rates availability in your area.


During the autumn, the cold winter and into spring, your heating system will have to deal with different temperatures. The operating of a traditional Electric Storage System is simple: storing all the heat possible while it is being charged, coinciding with the Time-Of-Use (TOU) or Time-Of-Day (TOD) low cost off-peak electricity tariff, and releasing it into the room during the rest of the day.

The greatest advantage of these traditional systems is their ability to provide a comfortable temperature at a really affordable price all day long.


In the case of Static Storage Heaters, also manufactured by ELNUR, the charge control is regulated by the “Dual Sensor” patented system. This system will switch the charging of the units on and off according to the temperature readings taken inside the equipment, inside the room and outside the home.

The “Dual Sensor” system of a GABARRÓN Static Storage Heater can help to cut electricity consumption by 15% compared to other static storage heaters in the market which do not include this system. energy consumption.

A Static Storage Heater normally uses the complete off peak charging period to load its core of energy at 100%. It will release this stored heat during the release period providing a 24 hours comfort.


In the case of Dynamic Storage Heaters (Fan Forced), the charging is performed in a similar way, but the main advantage of this system is how the release of the stored heat is controlled and the option of the stored heat being released when the customer really requires it. These storage heaters are ideal for large and open areas.

If the user manages the temperature optimally, storage heaters can result in an energy saving of 25%.

A Fan Forced Storage Heater will not use the complete off peak charging period because it will not discharge completely
the heat during the release period. It will only release the heat when it is strictly needed and programmed by the user.


ECOMBI includes an automatic charge adjustment. The temperature is continuously managed and the consumption assessed every day by the ESICC module. ESICC will define and adapt the charging and consumption during the off-peak charging period, taking into account the temperature needs established by the user in the room.

Another of the major benefits of the ECOMBI system is that, in the case of a sharp change in temperature or unexpected heat loss in the room, it can provide additional heat using a back-up heater.

The innovative ECOMBI System can reduce energy consumption by 35%.

When you use Dynamic or Static Storage Heaters on warmer days, you might find that the room is too warm and the desired comfort level is lost. This excess heat will be noted during the middle of the day, precisely when the temperatures are usually highest in a 24 hour day.

The innovative ESICC control module of the ECOMBI system automatically adjusts the charging, by assessing previous consumption and adapting to your desired temperatures. ECOMBI provides maximum savings in energy consumption.
