Abstract
The main cause of outbreaks of Legionnaires' disease is from contaminated water sources. About 3 in 10 cases of Legionnaires' disease are due to poorly maintained water storage in buildings. A Tankless water heater can reduce your water-heating bill by five percent to fifty percent or more. A Tankless water heater is a continuous flow of hot water because it instantly heats the water as it goes through the heater. The question is if the Tankless water heater is more efficient than the tank water heater? In our experiment, using Water Quality Management methods, the water heater tank was verified as a source of ubiquitous bacteria’s that can cause health problems to users. Are the solar hot water systems also dangerous? The use of solar energy is very prospective and in the future it will be used in various sectors. The subject of the paper is a simulation of the operational modes of hot water preparation focused on its temperature and energy impact.
Highlights
The water pipeline belongs to the technical systems currently used by people to ensure their supply of drinking and hot water
Important is its quality, which can be affected by the piping material, and by the chemical composition of water or by bacterial colonization. There is another factor in the preparation of hot water, namely the water heating technology, which can be a source of bacteriological colonization
There is the question of confronting heat and energy from the point of view of the use of storage tank heaters and the no-storage-flow systems, so called “Tankless” systems or instantaneous water heaters, which are common in the world in terms of reducing energy in the preparation of hot water
Summary
The water pipeline belongs to the technical systems currently used by people to ensure their supply of drinking and hot water. Important is its quality, which can be affected by the piping material, and by the chemical composition of water or by bacterial colonization. There is another factor in the preparation of hot water, namely the water heating technology, which can be a source of bacteriological colonization. Another type is the Heat Pump Water Heater. Heat pumps transfer energy from the surrounding air to water in a storage tank and they are much more efficient than electric resistance water heaters (most effective in warm climates with long cooling seasons). There is the question of confronting heat and energy from the point of view of the use of storage tank heaters and the no-storage-flow systems, so called “Tankless” systems or instantaneous water heaters, which are common in the world in terms of reducing energy in the preparation of hot water
