LOAD MANAGEMENT
All the advantages of the load management unit
“How much will I consume?”
This is one of the first questions those wishing to install an electric heating system ask.
If you are thinking about doing so, expect to hear that an electric heating system is inefficient and costly.
But don’t be put off: this is not true!
However, the topic of consumption deserves the utmost attention and must be managed intelligently.
HOW TO REGULATE TEMPERATURE AND CONSUMPTION
Customized sizing of the systems
All Warmset heating systems are dimensioned according to the real energy needs of the house. It will never happen that a system consumes more than is really needed, i.e. more than is REQUIRED BY THE HOUSE.
Limited consumption
Various solutions have been devised to limit the building’s energy consumption. Maximum energy consumption is limited and too much energy used at the same time is avoided; this results in a smaller control panel size, which translates into lower costs.
Temperature regulated in each room
The temperature is regulated in each room by a chrono thermostat or by a room temperature sensor in a completely independent manner. These instruments supply the input to the main load management control unit. Based on the maximum load set, the controller determines rotation of the loads.
Load management control unit
The load management control unit allows a reduction in energy absorption and consequently in the costs of using electric radiant heating. Moreover, the electricity meter is not oversized.
How the load management control unit works
Warmset has different types of load management, from the simplest mechanical types, to digital and home automation types.
Mechanical, digital, home automation: all the Warmset solutions
The basic operating logic of all load management control units is the following.
Based on the total load of the electric heating installed, the limit value of the maximum power that can be used by the system is set (taking into account the size of the electricity meter installed in the building). In the example, a radiant system with a total of 8.5 kW (with 6 kW electricity meter) in which the maximum threshold of 4 kW has been set is installed in a home. In this way, the sum of the loads cannot exceed the maximum threshold set (4 kW in our case).
The control unit gives priority to the coldest rooms (set point t° – room t° >1°C), heating the rooms closest to the set point t° set less. It does not switch on the heating in rooms with t° already at the set point. Upon reaching the set point t° of a room, the system recalculates a new rotation based on the set point t° farthest from the room t° (always giving priority to the coldest rooms).
When the various utilities are switched on, the system gives absolute priority to the utilities (washing machine, oven, dishwasher, etc.) by switching off the heating loads (under 4 kW), and keeping the maximum load below the threshold of the electricity meter (6 kW in our case).
The load management control unit can do much more!
Why settle for a load management unit when you can have a full integrated home automation system? In collaboration with one of the leading Italian industrial automation companies, we have created the home automation load management unit. In addition to managing loads, this control unit can communicate with the photovoltaic system. It supplies up-to-date data on production and coordinates with the control unit, to operate the electric radiant heating when the panels are producing energy, eliminating all operating costs. But the home automation control unit does much more! With the same system it is possible to manage the automation of lights, roller blinds, air conditioning units, gates and alarms. The initial investment is undoubtedly higher than required for a conventional control unit, but it allows unified control of all utilities in the home and significant savings in the connection and operating costs of the building. Energy control logic is optimized according to true needs and to external variables.
