BUFFER TANKSSIZING A BUFFER TANKThe sizing of the buffer tank, is based on the output of the boiler. The Greener Homes scheme had a requirement of 60 litres of storage per kilowatt. So for example, if you have a 25 kW boiler, then (25 x 60) = 1500 litre buffer is required. TYPES OF BUFFER TANKSBuffer tanks come in the following forms:
Sizes vary from 700L to 5000L.
1. STRATIFICATION BUFFER TANKThis buffer tank storage system stores the energy in layers. The SLS® stratification systems guarantee a constantly stable and therefore highly efficient tank. Flow and return of storage tank water is provided by internal stratification inserts in the flow and return line, in which the water sorts itself by gravity and then arranges in layers almost flow-less into the corresponding temperature zones. A surplus of energy can easily be contained and stored for a long time with only minor losses. Moreover, the water can be released quickly when needed. The Solarbayer stratification system optimally completes each heat generator without the need for any control systems. It operates maintenance free and with high operating reliability.

2. DOMESTIC HOT WATER TANKSThis tank is for heating systems that are not used in conjunction with a solar water heating system. There are two available, the 150 litre, and the 200litre. DHW Tank 150 L and 200 L - Specifications:
3. SOLAR DOMESTIC HOT WATER TANK SKLThis tank is used either in solar systems for the preparation of domestic water or in systems with a combination of buffer tanks. Due to the layout of the return line at the bottom of the tank, the temperature is 15°C lower than in regular solar tanks with standard heat exchangers. As a result of that, the efficiency and the performance of the solar collector is increased by up to 15%. Due to the vast heat exchanger in the upper area of the tank, the fuel value efficiency is guaranteed, even when refuelling with a condensing boiler. Therefore, the DHW output capacity of the SKL tank is higher than the output capacity of a regular solar tank. Solar DHW Tank SKL - Specifications:

BUFFER TANKSA buffer tank is a 'back up' or reserve tank for storing hot water which can be called upon as and when needed. It can be used in conjunction with solar water heating, and boilers as part of a central heating sysem. The water is heated by the heat source (solar, biomass or wood gasification boiler) to a set temperature in the tank and this hot water can be stored for long periods, until it is required. A buffer tank is required for wood pellet boilers and wood gasification boilers, as part of a heating system. Have some questions?Please see our frequently asked questions or feel free to contact us.
