Can QUERYTHERM be used for heating other than radiators?

No, QUERYTHERM can only be used when heating radiators. On a system for other types of heating, such as floor and crittal heating or radiant heating or air conditioning units, we are currently working.

How does QUERYTHERM regulate heat removal in the event of a change in heat sources (eg when people arrive in apartments, switch on appliances, open windows, etc.)?

QUERYTHERM utilizes sophisticated Just in Time technology that can accurately measure real-time temperature changes in the building, calculate passive heat gains and prevent unnecessary overheating.

What does predictive regulation mean?

Predictive QUERYTHERM capability is the ability of the system to reliably predict the actual heat demand in the building based on measurement data, weather forecasts and heating history.

How accurate are the data QUERYTHERM uses for weather forecasting?

To predict the weather, we use the most reliable data from the meteorological institute, whose reliability is confirmed by NRK, EUMETSAT, ECMWF, CHMI and MPO.

What is a three-way valve and how does it work?

QUERYTHERMU is a pipe fitting that determines the direction of the water flow in the heater controlled by the actuator.

How many branches of the heating system can one QUERYTHERM drive drive?

One unit of the QUERYTHERM control system controls two branches of the heating system as standard, but it can be extended to up to four (ie 2 basic branches + 4).

Does QUERYTHERM's installation really reduce the unpleasant noise from "footsteps"?

Yes, the noise level of the heater will decrease with QUERYTHERM as the thermostatic heads will be fully opened, the differential pressure equalization will be optimized and the heating system will optimize the flow of the heat medium.

Can I use the QUERYTHERMU to set the day and night room temperature difference? What about the attenuation of heating?

No, Quarytherm regulates itself when and how many temperatures the object needs to heat up. The user (object manager) can change the temperature of the building in the range of 19-24 ° C several times a day, with the speed variation being conditioned by many aspects (heating system size, thermal inertia, object position, weather, humidity).

Any reduction and consequent increase in temperature always means filling the object. Generally, 7% of energy is required to produce 1°C of heat. Therefore, frequent temperature changes lead to higher heating costs.

We insulated the building, but mold and moisture remain on the lower and upper floors. Will the status improve when installing QUERYTHERM?

Yes, humidity problems will improve because QUERYTHERM ensures optimal heating of the building by using heat gains while avoiding overheating of the building, thereby reducing humidity, constant thermal comfort and energy savings at the same time. If the building is not damaged by only 3°C, the building is at risk of dampness and mold, and in the case of overheating by 7 ° C, no heat savings are achieved against the unheated condition.

Does the QUERYTHERM heat control mean even for non-insulated houses?

Yes, the benefit of Querytherm is that it can not be re-set as other control systems when the building is later insulated or otherwise revitalized.

How can QUERYTHERM increase heating savings when we switch off the radiator in the apartment and therefore do not pay according to the consumption on the proportional meter?

If you turn off the radiator, it stops melting, but the heat is still supplied to the riser. And this heat, supplied to the building, is then allocated to apartments and added to the consumption of the apartment. The proportional gauge will also record the consumption on the body, and the heating costs will not show the actual energy consumed, but all the heat delivered. I.e. that the measured heat input is added to the measured consumption on the proportional meters, which, even when the radiator was switched off, was still supplied in the steps.

How do you use accurate flow meters and can they be used as billing documentation?

We use customized flowmeters with an accuracy of 10 pulses per liter, which is several times more accurate than the flow meters we use. The flow meters are approved according to MID for dynamic range 1: 250 and EEC and can be used as billing.

What minimal Δt (difference of heating and return water temperature) is able to measure your flow meter?

The flowmeters used for the QUERYTHERM thermal control measure Δt = 0 ° C with a deviation of one hundredths.

How does one-component heat distribution differ from two-component?

The one-component price is the total GJ heat delivered and the two-component consists of the price for the connection to the network and the price for the heat removed.

What quantities are measured by QUERYTHERM?

QUERYTHERM measures the pressure in the heating system, flow rate and return and return temperature, and outside temperature. Other measured values ​​are part of the QUERYTHERM patented technology and we do not publish them.

Is QUERYTHERM compatible with energy management systems and how difficult is its connection?

QUERYTHERM's compatibility with other thermal control systems is possible but not necessary.

Do QUERYTHERM need to connect to something or is it a complete solution?

No, QUERYTHERMU® no longer needs to add anything to it, because it is a completely separate and complete solution thanks to the web application and its own visualization.

How does QUERYTHERM account for internal heat gains and what role do the thermostatic control heads play?

QUERYTHERMU takes into account internal heat gains by increasing the return temperature when the heat transfer to the heated space is reduced or when the thermostatic heads are closed. These earnings with Querytherm learn to recognize and estimate in advance after the test period.

Does QUERYTHERM affect the flow and the heating water temperature?

Yes, the Querytherm system is completely autonomous in this respect.

Are the thermostatic valves on heating radiators not enough?

The thermostatic valves limit the supply of heat to the very end of the heating system (radiators) and therefore can not limit the entry of excess heat into individual boilers. The influence of the riser on the heat consumption is the greater the more the object is insulated. Incorrectly installed thermostatic valves, in addition to their operating principle, greatly degrades the flow of heating water, which negatively contributes to thermal short-circuits and bridges, resulting in the failure of certain bodies and places in the building.

Is balancing valves just enough for heat control?

Generally, balancing valves improve water flow and heat delivery, but do not address the amount of heat delivered to the heating system.

What can we expect to change after installing Querytherm?

First and foremost a significant saving in heating costs. At the same time, the noise of the heating system and the heating system dynamics will be reduced. The temperatures in the heating system will stabilize and reduce the temperature in the boiler and the medium temperature of the radiator, ie. that the heating will be colder for somebody than before, but that does not mean they do not. The footsteps can no longer be used primarily to heat the room instead of the radiator.

When I touch the radiator is cold - does it mean that the radiator does not melt?

The radiator is heating up, but the term "cold" needs to be specified. If the room temperature is, for example, 21 ° C, the radiator has a temperature approaching or the same as that of the human body, and therefore seems cold to the touch. Because the average body temperature on the body surface is in the range of 35.8-37.3°C, the heating temperature is 16.3 ° C higher than in the room, which means it melts.
