Hello!
We have a brand-new heat pump that also provides regular hot water. For the shower, the set temperature of about 43°C (109°F) is sufficient. According to the installer, going above 45°C (113°F) would cause the electric heating element to work too much, making it uneconomical.
There are two of us, both working. In the kitchen, we occasionally need warmer water for washing dishes or cleaning during the week, but not multiple times a day. Therefore, we don’t need a storage tank and are considering buying an instantaneous water heater. An electrician could connect it to the stove with a "switch."
We would prefer not to replace the faucet. I have no idea what type it is—it just looks nice ;-). I have heard something about low-pressure systems, though.
What would be the best solution here?

I think that’s nonsense. A heat pump converts 1 kWh of electricity into 3-5 kWh of heat. An instantaneous water heater converts 1 kWh of electricity into almost 1 kWh of heat.
On the other hand, there are storage losses when storing hot water.
By the way, a heat pump should be able to reach more than 45°C (113°F), even without an auxiliary electric heater. However, efficiency will decrease.
I recently read that cleaning with warm water is a myth. The cleaning effect comes solely from the chemicals used. Besides, 45°C (113°F) is not exactly lukewarm.
