On the basis of the temperature signal from temperature sensor 20 and the velocity signal from the speed measuring element the microcontroller 19 can therefore determine the momentary flow rate and the associated temperature of the liquid flowing in the pipe. On the basis of the flow rate and the temperature the microcontroller 19 computes the momentary power (energy per time unit) flowing into floor heating system 1 via warm water feed pipe 2. In another embodiment shown in broken lines in figure 1, heat meter 14 also comprises a second temperature sensor 22 which is placed in return pipe 3.
  • second temperature sensor 22 is connected to microcontroller 19 and provides microcontroller 19 with a signal representative of the momentary temperature of the water in discharge pipe 3. If it is assumed that there is no loss of water in the conduit system, the flow rate of the water supplied in feed pipe 2 is the same under stationary conditions as the flow rate of the cooled water in return pipe 3, so that a separate flow rate meter in return pipe 3 can be omitted. The two power associated with supplied water and the power associated with cooled water are subtracted from each other in this embodiment in order to compute the supplied heat.
  • Heat meter 14 is also provided with an LCD screen 23 on which can be read in known manner, among other information, the momentarily supplied power, the (accumulated) power supplied over a determined time interval, the feed water temperature, the discharge water temperature, the temperature difference, the water flow speed, the momentary flow rate in the water feed pipe and so forth.
  • Heat meter 14 is suitable for invoicing purposes, which is understood to mean that for the supplier of the warm water it keeps track of how much heat is supplied to a user and the cost which can be billed for this supply.
  • Such heat meters 14 are often, though not always, already present in district heating networks (systems with individual warm tap water as well as collective warm tap water (IWT/CWT) and in apartments with a shared CH apparatus) .

  • Control valve mechanism 32 is arranged in feed pipe 2 and can adjust the flow rate of the liquid flowing in feed pipe 2 in stepped manner or in continuously variable manner. Such control valves are generally known and a detailed description thereof is therefore omitted here.
  • the control valve can also be arranged in return pipe 3 instead of in feed pipe 2.
  • control valve does not hereby change, although this can be recommended because the average temperature of the return water is lower than that of the supplied water.

  • temperature sensor 8 is connected to microcontroller 19 or microcontroller 27, and provides to microcontroller 19, 27 a signal representative of the momentary temperature of the water in pipe 7.
  • Microcontroller 27 of control unit 26 receives via input terminal 29 a signal from heat meter 14 which is representative of the power being delivered at that moment to the heating system. Microcontroller 27 likewise receives a signal from thermostat 34 via input terminal 30.
  • Thermostat 34 is arranged in a random room, usually for instance the living room, of a dwelling, and comprises a temperature setting button 40 with which the user can set a desired temperature (T 1 ) .
  • Thermostat 34 also comprises a temperature sensor 41 with which the temperature (Tj of the ambient air of thermostat 34 can be measured. This temperature is representative of the temperature in the relevant room.
  • thermostat 34 When there is a difference between the temperature (Tj measured by- sensor 41 and the set temperature (T 1 ) , thermostat 34 generates a signal representative of this difference to input terminal 30 of control unit 26. On the basis of this signal and on the basis of the signal at input terminal 29 thereof, this signal being representative of the power determined at that moment, microcontroller 27 of control unit 26 computes how the set temperature (T 1 ) can be reached, as optimally as possible energetically and with maximum comfort for the users, by adjusting the flow rate through feed pipe 2. Once control unit 26 has determined which flow rate is at that moment desirable, it sends a signal via output terminal 31 to control valve mechanism 32 which places the control valve in the desired position. In the shown embodiments the circulation pump 9 is also actuated by control unit 26.
  • valve mechanism 32 With a correct adjustment of the quantity of warm water supplied from feed conduit 2 and a correct mixing with the cooled water from the return conduit, the three-way valve of valve mechanism 32 substantially provides in this embodiment for the temperature of the water flowing through the floor heating conduits, while circulation pump 9 substantially provides for the flow rate of the water.
  • the control unit controls only the control valve mechanism, as will be set forth below.
  • control unit 26 therefore determines the desired flow rate through feed pipe 7 on the basis of the power of the water being supplied at that moment as well as the air temperature of the room to be heated or made cooler.
  • An extremely- efficient driving of the heating system can be realized through the direct link between the current air temperature, the desired temperature and the momentary power.
  • heating system 1 shown in figure 1 the heat meter 14, control unit 26 and control valve mechanism 32 are shown as separate components.

This can result in space and cost- savings .
  • Figures 1 and 2 show that the power supply 35 for heat meter 14, control valve mechanism 32 and control unit 26 is shared and is provided from the domestic mains supply (H) . This means that batteries or accumulators present in many cases in a heat meter 14 can be dispensed with, this achieving a further simplification of the system.

  • the radiators are provided for this purpose with setting valves 51,51',5I 1 '. These setting valves are given a certain adjustment during said setting.
  • the setting valves must not be confused with the (thermostatic) radiator valves operated by the resident . Because the regulation according to the invention makes use of a heat meter with which, among other things, the flow is accurately measured, this measurement can be used in the hydraulic setting of the heating installation. Setting takes place as follows.
  • the radiators are closed except for the radiator to be set.
  • the radiator valve is fully opened and the setting valve is adjusted so that the flow through feed pipe 2 (which flow is accurately measured) acquires the desired value.
  • the regulation takes place on the basis of input parameters such as hydraulic pressure difference and/or water temperatures and/or room temperature.
  • the regulation according to the invention makes use of rapid and precise measurements of the quantities of feed and return temperature of the water, the flow rate, the power and, for the more refined variant of the regulation, also the prevailing and desired room temperature.
  • the regulation according to the present invention is hereby better able than the currently available regulating means to respond adequately to changes in the setting of radiator valves. These changes are detected immediately and the regulation can also respond immediately.
  • the power delivered is measured precisely with a heat meter, it is likewise possible to precisely regulate the power which is delivered.
  • the power of a unit can also be limited very easily due to this accurate measurement.
  • Another form of limiting is the limiting of the flow through the unit, with the object of limiting the flow through the radiators as a comfort-enhancing measure (less noise) .
  • the maximum flow speed through the radiators can be determined and adjusted quite precisely.
  • Another advantage of the regulation according to the invention is that the so-called off-peak hours reduction (which is frequently applied to a relatively rapid room heating system with radiators) can likewise be applied to floor heating systems. These latter systems are considerably slower than systems with radiators, whereby the floor heating is usually left on at night.
  • the regulation according to the invention is better than the control systems applied heretofore and in many cases brings off-peak hours reduction within reach in the case of floor heating.
  • the supplied energy is determined by integration in time. This is used, depending on the number of hours that there is no heating and depending on the difference between desired and actual room temperature, to employ a higher feed temperature than is normally permitted in respect of the safety margins which must be observed (the floor may for instance not become too hot, etc.) .
  • the higher temperature is maintained until there is the danger of exceeding an energy level to be more definitely determined. This increases the possibilities of off-peak hours reduction in floor heating which, despite the temporarily higher feed temperature, can be energy-saving .
  • warm tap water supply in most cases forms an integral part of the heating system according to the invention.
  • warm tap water supply There are basically two types of warm tap water supply.
