Optimize Any Hydronic Heating System with BuffMax® by Thermo 2000
The BuffMax® thermal storage tank is a high-performance 3-in-1 solution designed to optimize and improve the efficiency of hydronic heating systems. Acting simultaneously as a buffer tank, storage tank, and hydraulic separator, BuffMax® is ideal for use with:
- Low-mass boilers
- Biomass heating systems
- Geothermal systems
- Heat pump systems
- Multi-zone hydronic systems
- Solar thermal energy systems
🔋 Buffer Tank – Reduce Short Cycling & Maximize Boiler Efficiency
In hydronic systems, short cycling occurs when the system load is lower than the energy source's minimum capacity, leading to frequent on/off cycles, premature equipment wear, and energy waste. The BuffMax® buffer tank increases runtime efficiency and helps prevent these short cycles, extending the lifespan of heating equipment and reducing energy consumption.
Benefits:
- Prevents boiler short-cycling
- Enhances system longevity
- Maintains steady water temperatures
🌡️ Storage Tank – Store Thermal Energy Like a Battery
The BuffMax® thermal storage tank acts like an energy battery, storing heat and releasing it only when needed. During low heating demand periods or when used with a low-capacity energy source, such as solar or geothermal, the tank helps deliver immediate thermal energy without activating the primary source.
Ideal For:
- Partial load or intermittent heat demands
- Reducing startup cycles
- Enhancing solar and renewable integration
🔄 Hydraulic Separator – Improve Pump & System Performance
By functioning as a hydraulic separator, the BuffMax® improves system flow, balances circuits, and protects pumps and other components. It effectively removes air, sludge, and debris, helping maintain the efficiency and safety of the hydronic network.
System Optimization:
- Ensures optimal pump operation
- Removes air and impurities
- Balances flow between energy source and distribution
🌍 Compatible with a Wide Range of Hydronic Systems
BuffMax® buffer tanks are highly recommended for:
- Low-mass boiler optimization
- Multi-zone hydronic heating
- Biomass boiler integration
- Solar water heating systems
- Heat pumps and geothermal systems

Let customers speak for us
The boiler works great easy install. But the tech support we got hold of was in French so not a lot of help.manual was easy to follow on wiring
Easy purchase - exactly what I needed
Plumber was very happy with it. So are we.
I’ve been using Everflux for some years now and it’s simply the best there is.
Excellent product for descaling tankless water heater.
Once again, great quick service
Good go,, 👍👍👍
Great service. Happy to find the products I needed.
Great place to order from. No complaints.
Had everything i needed and step by step directions!
Excellent product! Customer service via email was timely & supportive... Shipping was quicker than expected... Thx!
Great service, quick, my new go to store/website
Works really well, this seals well also.
Dont use too much and dont put that much heat on it.
Haven't tested when water is in the system but over all is better than oatey no 5.
I am very happy with my experience. We had a shipping issue on my first order, and after working with PLUMBESTORE, they sent me another part ASAP. The part arrived very quickly and as described.
Very good product
