HDG Buffer tanks

HDG buffer tanks come in various sizes, from 500 litres to 5000 litres. We recommend about 25 litres of buffer tank for every 1kW of boiler thermal output.

Buffer tanks are used with any wood pellet boiler or other solid fuel boiler to allow the boiler to run for long periods without stopping and starting.

They also help a heating system to respond quickly to changing heat loads; and as a heat store, it can provide more heat, for short periods, than the boiler could alone.

The buffer tank sits between the boiler and the heating and hot water system acting as a buffer between the two. This allows the use of a variety of sophisticated controllers that otherwise wouldn’t work with a wood pellet boiler.

Each buffer tank has four inlets and four outlets at top, bottom and equally spaced in between. They also have four pockets for temperature sensors. This allows a variety of different heating system configurations.

Each tank comes with an insulating jacket made to fit the tank and all its connections.

These tanks can be used in conjunction with solar collectors to make an integrated wood pellet / solar thermal heating system.
