Buffer Tanks

Why use a buffer tank for biomass?

Specialists in bespoke buffer tanks of all sizes, call or email us, we can almost guarantee to beat any price.

Biomass boilers take a while to heat up compared to gas boilers so to provide instant heat a buffer tank is fitted with temperatures of 70-90 degrees at all times. The biomass boiler only looks at heating the buffer tank to a commissioned temperature relevant to heating requirements. This is usually done by having a high and low buffer temperature sensor linked back to the biomass boiler. Once the buffer bottom temperature is reached the biomass will shut down and turn back on once the top buffer temperature drops to a preset switch on temperature. Therefore the heating demand is drawn from the buffer tank to the property  that has a storage of hot water from 70-90 degrees at all times. It is very important to size the accumulator tank in accordance with the boiler size. If the buffer tank is too small then the boiler will switch on and off too much which is not very efficient. If the buffer is too larger then the buffer tank will struggle to get up to temperature and work at 100% output for longer periods of time, this can cause additional wear and tear on parts and end up being expensive replacing parts.

Buffer tanks also known as accumulator tanks or thermal stores. Our Standard Buffer Tanks Range from 500 to 8000 l, As standard they come with insulation. We offer fast delivery times on buffer tanks, usually between 1 and 3 days if required.

A basic buffer tank has no coils inside and is perfectly designed to work with a biomass boiler.

We also offer bespoke buffer tanks.

Small and large buffer tanks ranging from 1000L - 25000 L.

For much larger requirements we can now offer buffer tanks upto 100,000L. And even 200,000L buffer tanks, Give us a call to discuss your requirements. We can offer 10,000L buffer tanks, 15,000L buffer tanks, 20,000L buffer tanks, 30,000L buffer tanks, 40,000L buffer tanks, 50,000L buffer tanks, 60,000L buffer tanks, 70,000L buffer tanks, 80,000L buffer tanks, 90,000L buffer tanks, 100,000L buffer tanks, 125,000L buffer tanks, 150,000L buffer tanks, 200,000L buffer tanks and 250,000L buffer tanks.

You can design a bespoke buffer vessel to your exact requirements by using our Bespoke Tank Designer.
