buffer tanks

What is the Buffer Tank and what is it used for

Buffer tanks are tanks (extra space) for storing water (hot or cold).

Storage of hot water (radiator or underfloor heating) or domestic hot water (DHW)

The buffer tank is connected in series with the boiler (whether it is an oil, gas boiler, pellet – biomass boiler, wood boiler, heat pump) or with solar collectors.

This is a tank with very good thermal insulation, in order to maintain the high temperature of the water for a long time. The purpose of the buffer tank is to store hot water when it is produced during the operation of any type of boiler, heat pump, or solar collector and to provide us with hot water when the boiler or heat pump stops operating or when the sun goes down and the solar panel stops producing hot water.

For example, if a heat pump or boiler is running from 6 to 10 at night, during these 4 hours it produces hot water of high temperature, which is transferred through the circulator to the radiators or to the underfloor heating system, offering thus space heating. During the operation of the boiler or heat pump, hot water is stored in the buffer tank. When the boiler or heat pump stops operating, the circulator begins to transfer to the radiators or underfloor heating system, the hot water stored in the buffer tank, thus providing free heating for many more hours.

In this way we achieve energy savings, and therefore money, since we use the hot water of the buffer tank (BUFFER-0) and the boiler or heat pump does not need to be running continuously to have hot water in the radiator in the underfloor system. The same applies to domestic hot water (DHW) if the buffer tank (BUFFER-1) is connected to solar panels or to an buffer tank (BUFFER-1 INOX) with a stainless steel heat exchanger.
Also in the case of heating produced from electricity (heat pump, resistors, electric boiler) the buffer tank can store energy taking advantage of the hours with the low price of the PPC overnight tariff.

Cold water storage

Buffer tanks operate in the same way as above for cold water storage (instead of hot) with the only difference that instead of being connected to solar collectors  or boiler, connected to water coolers. Here, too, we achieve energy and money savings due to the fact that even though the motor of the refrigeration machine has stopped working, the circulator continues to transfer cold water from the buffer tank.

Megasun Sunscreen buffer tanks have many “import-export” (1 “& amp; 1½”), so they can be connected to many types of heat sources (wood boilers, pellet burners, heat pumps, oil or gas boilers, gas boilers, boilers electric ion boilers, energy fireplaces, solar panels), offering not only economical heating but also free hot water.

Buffer tanks of this type can be connected with a low-temperature heat pump, gas-oil-pellet boiler in combination with solar panels and offer hot water through the large stainless steel heat exchanger they have, according to the following blueprints:

The installation of solar systems for the supply of hot water (collector, water storage tank, support base, piping, boiler, inertia tank, etc.) is subsidized by the program “ ΕΞΟΙΚΟΝΟΜΩ – AYTONOMΩ ” of the Ministry of Environment, Energy & amp; Climate Change.
