Will the video below dispel any doubts?

Certainly not, because almost every building is different and its use may vary significantly. However, it is worth getting acquainted with this information and considering the pros and cons

Everyone must consider such choices individually. It's all about not only the cost of heating, but also the cost of purchasing these solutions. Heat pump + underfloor heating installation and boiler room equipment, versus Electric storage heating . And I leave this for individual consideration.

There are a lot of differences in the comments. It is certainly worth emphasizing that a heat pump can also store a large amount of energy during the hours of the cheap G12 tariff, with underfloor heating and, preferably, a large buffer. Even though the pump efficiency at night will be lower than during the day, because the nights are usually colder, the COP will still be within the range of 1.5 - 2

When deciding to buy a heat pump, pay special attention to the cheapest and most expensive to operate devices from China, which dishonest companies sell to customers at minimal cost. Thus, taking the subsidy money and leaving the customer with sky-high electricity bills.

The heat source is one thing, but a factor often overlooked during construction is the building's energy demand. And this is a key factor, because all the energy produced for heating escapes from the building with the properties of a colander. And even with the best heat pump in the world and photovoltaics, the bills will be high.

Good house design is the basis, the rest is an addition.
