Seeking Settings for the Slowest Heat Up

[simon-bd]

Hey wonderful community!

I'm reaching out for some guidance as my current home setup is becoming a concern with a little one on the move. With digital TRVs ability to fully opening the valves, the rapid heat-up is making radiators scalding hot, posing a potential risk for my child.

Since I'm a renter and can't modify the valves, I'm exploring ways to achieve a slower and gentler heat-up. I've asked my landlord about changing the valves for ones that have presetting, but it seems like a challenging route since dumb trv's would fix the issue 🤦‍♂️.

Has anyone faced a similar situation or found a workaround for a gradual heat-up with digital TRVs? I'd love to hear your experiences and any suggestions you might have!

Thanks a bunch! 🙏

@KartoffelToby would you mind taking a look at this when you have a spare minute :)

Im new here but if I was faced with this issue I would be inclined to reduce the flow temperature of my boiler. a) to reduce the chance of a skin burn and b) to reduce the already prohibitively expensive gas supply.

You should increase the flow. Then you can lower the temperatures, because your heater is in general warmer. By that you will lower the cost of gas.

Example 1 slow flow:
Flow temp: 55°C
Return temp: 30°C
Average: 42.5°C

Example 2 fast flow:
Flow temp: 45°C
Return temp: 40°C
Average: 42.5°C

Also a slow flow means you burn the skin more likely, because you need a higher flow temperature.
Fast flow helps your boiler as well to save some gas, because it does need to heat up the water too much.

@leckytech I live an apartment building and the building is supplied from an external source for heating :)

Why dont you use a scheduler to increase temp with few (0.5-1) degrees every 2-3 minutes up to the target temperature ?

Was hoping better thermostat would implement something like that :)
