​Preparation Checklist:

  1. Find the potential places for Heatventors' Thermal Battery: where can it fit? statics issues? distance from other equipment?

  2. How the Thermal Battery will be transferred there: is there an elevator, is a crane needed, etc(together with the 1st point)

  3. Where can the HeatTanks be connected to the existing cooling system: The main cooling pipeline should be identified and potential points for the connections. One pipe should be connected to the supply pipeline and two to the return pipeline.

  4. How is it possible to connect the main pipeline with the HeatTank's in space?

  5. One electric plug is required for the control system, where can we get the electricity from (usually there are free electric plugs in the electric box of the chiller), maximum need: 24 W

  6. Photos, videos are essentials, without it is nearly impossible to start the planning

  7. Statical plans, HVAC schematics, P&I, floor plans should be asked for

Heatventor' Thermal Battery systems can be installed indoors in HVAC rooms, warehouses, parking lots, basements, garages. It can be placed outdoors on the roof or on the ground next to the building. When installing outdoors, we recommend that the Thermal Battery should not be exposed to direct sunlight (increases heat loss).


HeatTanks can be placed directly next to each other, as they do not require maintenance.

It is recommended to leave 1 meter each side, but if there is no space it is not necessary.

The installation process can be started by pre-installing the pipes (and closing the pipeline with valves) and later placing the Thermal Battery under the pipes.

Heatventors' Thermal Battery can only be stacked using a specially designed support structure (we do not manufacture such a support structure) because the heat exchanger nozzles are located on top of the HeatTank.

Overall, the installation is very simple and quick process, the Thermal Battery is as plug and play system. Installation is usually done through subcontractors or by the partner's own maintenance/installation team, we provide the plans and support the installation, if needed.


Steps of the installation:

  1. Design of a suitable support structure (e.g. machine base), if necessary

  2. Moving the HeatTanks to their place

  3. Preparation of the bypass pipelines from the main cooling pipeline: can be done by inserting T-junctions, but the recommendation is to use T-saddle. Then the butterfly valves should be installed and the cooling system can operate without disturbance

  4. Make the piping according to the drawings and following all the connecting guidelines

  5. Connect HeatTanks to the pipeline and plug the electric supply of the pump (if required)

  6. Pressure test

  7. Filling the phase change material into the HeatTanks:

    • For cooling solutions, the filling phase change material arrives in 170 kg “oil barrels” or 1 m3 IBCs and is in a liquid state (viscosity similar to water), non-toxic, non-hazardous in any way, simply can be pumped into the Thermal Battery through the opening on top

    • For heating solutions, the material usually arrives in 25 kg bags in the form of flakes or granules, which can be easily poured into the Thermal Battery (if necessary, the entire top of the HeatTank can be removed)

  8. Connect the temperature sensors, valve motors, heat consumption meter to the control system of HeatTanks and plug the control system to a normal electric plug. The system is basically plug and play using jack connections, connecting to the BMS system is also very easy
