Hot Water Systems – Options Available

Natural gas – can be used in storage boilers as well as instantaneous water heaters. Natural gas systems are rated for their energy efficiency and are available in both internal and external models. Gas heaters have a lower capacity than exclusive electric units because they can be heated at any time of the day or night, and not only for a certain period of time.

Off-peak electricity – has the same operating costs as a natural gas system but is only available if the system has a storage capacity of 160 liters or more. Hot water is usually heated at night and used during the day.

Solar energy – it can meet up to 85 percent of your needs for free, making it a very eco-friendly choice. They are the cheapest system, but have a high investment cost. All solar systems are equipped with a "propulsion" energy source (such as gas or electricity) to provide hot water when solar radiation diminishes. Line pressure and constant pressure are also available.

Peak Electricity – used for electrical and continuous heating units of less than 160 liters. Operation can be expensive but is very popular in areas with limited space, e.g. in small houses, apartment blocks and apartments.

LPG – used in areas where natural gas is inaccessible. Suitable for heat systems with continuous flow and storage.

Solid fuels – including wood, coal, briquettes, etc. Fuel prices can vary widely. Solid fuels can be used alone or in combination with electricity or solar energy in a constant pressure system.

Heat pump – very efficient and uses about 75 percent less electricity than other electric hot water systems. They extract heat from the atmosphere with the help of refrigerant gases and compressors. They use heat to heat water stored in tanks near the ground.
