Hot water heating trough HA #89

Open timg83 opened 5 months ago

timg83 commented 5 months ago

Hi

I have a Weishaupt heatpump with a boiler for hot water.

I want the heat pump to create hot water when I have sufficient solar power instead of doing it on a regular time base. I want to make the hot water even hotter than normal so it stays hot for longer time.

How can I force the heat pump to make hot(ter) water trough HA? Does anyone has an automation for this?

Thank you!

Tim

The easiest way to do this would be by adjusting the wanted boiler temperature. In my case, this would be done by modifying number.warmwasser_normalww. However, names and supported functions may vary, so I recommend reviewing all available options under your Device in the configuration for this integration.

Hi @erikkastelec

When I change the wanted boiler temperature I observe that that the heat pump does not immediately start heating the water. I see in the statistics that it takes almost an hour for the heat pump to start heating up the water.

When I have excess solar power I want to use it immediately to heat the water. Do you know if that is possible and how to do that?

This is probably due to dynamic switching setting that is located under heat pump tab on expert page on WEM website. Try turning it off and it should follow your set temperature more closely.

If you find a better solution, let me know.

Maybe this is due to the deltaT?

The heatpump has a setting how much difference of measured to set temperature is allowed. I have 5 Kelvin. My normal warm water is set to 45°C. When i set it to 55°C it starts nearly immediately.
