Instant water heater instead of heating system?

Hi there!

We have a brand new heat pump that also provides regular hot water. For the shower, the set temperature of about 43°C is sufficient. From 45°C onwards, the heating element would probably work too hard, making it uneconomical, according to the installer.

We are 2 people and both employed. In the kitchen, we sometimes (during the week, not more often per day) need warmer water for washing up or cleaning. Therefore, we don’t need a storage tank and are considering buying an instantaneous water heater. It could be connected to the stove with a "switch" installed by an electrician.

We would rather not replace the faucet. No idea what kind it is. It just looks nice ;-). I’ve heard something here about low pressure etc.

What is the best way to handle this?

I consider that nonsense. The heat pump converts 1 kWh of electricity into 3-5 kWh of heat. The instantaneous water heater converts 1 kWh of electricity into almost 1 kWh of heat. In contrast, there are storage losses for storing the hot water. Incidentally, the heat pump should also be able to reach more than 45 degrees, even without an electric heating element. However, the efficiency will suffer. I recently read that cleaning with warm water is a myth. The cleaning effect comes solely from the added chemicals. Moreover, 45 degrees is not exactly lukewarm.

By the way, the heat pump should also be able to reach more than 45 degrees, even without the heating element. However, the efficiency will suffer.

Women just want it warmer ;-)

Give her a kettle.
