The author compares the instant water boiling technology and the use of electric teapots in the article. Strengths and weaknesses of the instant water boiling technology and its integration into the internal water supply system are also demonstrated.
Aqua Hot 98 instant hot water dispenser is capable of heating up to 60 cups in an hour, while consuming 20 % of the electric power needed to boil the water on a stove or in an electric tea pot. Besides, the water is ready for consumption at any moment of time.
The amount of water heated by the instant hot water dispenser is the one that is needed at a particular moment of time; electric power and water consumption rates are efficient enough to guarantee substantial reduction of utility payments.
Given the fact that Aqua Hot 98 instant hot water dispenser is also capable of supplying cold filtered water, the proposed technology is more economical and ecological that bottled water supply, as plastic bottles accumulated at junkyards damage the environment.
The weakness of the proposed technology is its cost, as it is far more expensive than an electric kettle.

In the article the short historical review on the design of sanitary rooms and their configurations is given. The main errors of the recent years, which led to the decrease in accommodation convenience because of the wrong approach from both the architect and engineers, are given. It is possible to use a small useful area for sanitary facilities, but it is connected with the lack of possibility of connecting washing and dishwashers. The author considers the options of engineering equipment placement in sanitary rooms taking into account the convenience of use, safety, and also resource-saving aspect. Various solutions on the organization of heating and ventilation are provided. The possible technical solutions allowing solving a flooding problem of the first floors in elite housing estates in case of accident are offered with the help of full waterproofing of sanitary rooms, and also the whole area of the apartment. The main attention was focused on the improvements of sanitary rooms for one-room and two-room apartments, which are the most demanded in the modern market of real estate. Layout solutions of the reduced bathrooms on the placement of the necessary equipment with choice justification are provided. The attention is paid to the layout solution for modern kitchens on order to increase their comfort by the use of special two-section sinks, and also a grinder of food waste in order to allow to lower the load of the systems of rubbish disposal of a building, by dumping the crushed garbage in an internal sewer network. Various options of evolutionary development of sanitary rooms for increasing the comfort degree are given. First of all, the development should happen in the direction of not only sanitation and hygiene, but also of the maintenance of the physical health of the people living in the building. It can be carried out by increase in a useful area of sanitary rooms, installation of exercise machines, medical bathtubs and a Jacuzzi, which allows receiving good relaxation after a difficult day. Also one more direction will be the organization in occupations of an aquacycling, so-called water trainings in a special bathtub by means of exercise machines for strengthening of health of the population.
