Upgrade underfloor heating with actuators and wireless receivers

What does this have to do with the losses?

The system always remains the same, even with radiators, determining the necessary flow for the rooms and regulating the temperature via the heating curve.

The only thing that changes with higher losses is the supply temperature, which rises.

Six, sit down.

For the calculation of the hydraulic balancing, the structural data of the rooms must be precisely known (especially the heat loss), because otherwise the heating load cannot be determined accurately. A thermal balancing is then only the step after next in the whole chain.

The thermal balancing to the hydraulic balancing is comparable to a relationship like a combustion engine with injection to one with a carburetor and choke.

And then there are further factors, where it turns out that an ERR suddenly is the more efficient way.

General statements such as: "Every underfloor heating system can be controlled particularly efficiently without an ERR" or "in normal cases, any type of thermostat control in an underfloor heating system is counterproductive" are simply and plainly wrong.

How much is the annual or monthly gas consumption?

So in the last billing period we consumed 19,334 kWh of gas for a single-family house (4 people) with 165 m2 of living space and a total of 12 underfloor heating circuits and an additional 3 normal radiators.

when I switch to such actuators, do you happen to know what size (screw) they need to be?

Ok so you have a combined system with two heating circuits, i.e. underfloor heating + radiators, meaning low temperature and high temperature, or are the radiators also in the low temperature variant?

That’s why I already wrote further up that you would need someone on site. If I’m not mistaken, it should be 30x1.5. If I were you, I would simply measure.

So you currently have roughly double (rather triple) the consumption of a modern energy-saving regulation house.

You don’t overdo it with the heat and regulate everything manually? Am I right with that assumption?

Low temperature and high temperature

I'm not sure about that, but the HK are actually always off.

If I were you, I would just measure

So take off a valve and measure the thread in height and width?
