Buffer Tanks

Mainly used as the main heat storage medium for biomass boiler systems, accumulator tanks help wood or log fired boiler installations to efficiently store large volumes of primary heating water.

Typically,  buffer tanks can store heating water for long periods due to there thermal efficiency and layering properties. When used in conjunction with effective mixing and loading valves, they can help to get the best use out of your biomass boiler.

We can help you with buffer tank sizing, and selection. Provide all the accessories that you will need to install the tank, and help with system design.

With tanks from 500 litres to 7000 litres, we have an accumulator tank to suit any wood fired boiler project, and can supply all areas of the UK.
