From the advertisement for this pump I can read: “The new EHS Mono HT Quiet is able to consistently provide hot water of up to 70°C for domestic heating purposes.¹ This can make it a suitable replacement for gas boilers, as they provide a high leaving water temperature. With its strengthened parts …

[image] Michal_S: took 5C from my HDW tank which dropped below 45C and immediately triggered the re-heat of tank again to 50C Where is the temperature sensor placed within the tank? How much kWh of heat was put back into the tank afterwards? Have you considered increasing the reheat threshol…

Thanks, I will have a look. Do you really think once per month is enough ? I’m not overaly concerned but I also don’t know what to think about this legionella in general. Never thought about it, never thought on my DHW temperature (electric boiler before). Scalding is not an issue here, I have therm…

Re Legionella Risk. There are two types of electric showers, one just uses the mains pressure if > around 2bar, so no risk as minimal residence time, ~ 4sec in the 250ml heating can at a minimum flowrate of 3.5LPM. There are also pumped types with a integral pump fed from the CWSC which can often r…

[image] Michal_S: Do you really think once per month is enough ? I’m not overaly concerned but I also don’t know what to think about this legionella in general. Personally, I don’t bother at all; heating my tank from 20° to 45° works fine for my household. [image] Michal_S: reheat will b…

That’s right. Maybe I’m overthinking. I guess I will set it to 48C with reheat when temp drops by 8C. so it starts again at 40C. I probably disable legionella cycle or set it to 55C once a week without immersion heater.

Hi guys, does anyone knows why heatpup started to heat water when temperature was 44C ?? [image] In field settings I have START temperature set to 8C (STOP 0C), DHW temperature I have set to 48C so I would expect it would start to reheat when temperature drops to 40C. During night I had DHW turne…

My Mitsubishi would always start a DHW cycle as soon as DHW was turned back on, regardless of the current temperature. So maybe that’s what the Samsung is doing?

Hi @Michal_S . I think @Timbones is correct, if you still have your #3011 set to 2. The Installers Guide says: If FSV #3011 is set to 1, the DHW operation starts based on the thermo on temperature, but stops at thermo off temperature. If FSV #3011 is set to 2, the DHW operation starts, but stops …

Hi @Timbones @SarahH , Could be but I’ve expected it starts only when the water temperature is below a set offset. Currently legionella cycle is disabled since I haven’t installed immersion heater yet. I have it at home but I would have to half empty the tank to install it :slight_smile: I guess af…

[image] Michal_S: But indeed it’s probably because I have #3011 set to 2 - Hysteresis. You might be confusing yourself, @Michal_S , calling #3011=2 Hysteresis. Hysteresis is actually set by #3023. [image] Michal_S: So if I understand Sarah, if I want to start exactly when water temp drops…
