More power

  • Available in twelve outputs, ranging from 75kW to 1MW
  • Can be cascaded to achieve even higher outputs of up to 8MW
  • Has turn down ratios of 1:6 and can heat up to 95℃*
  • 20% hydrogen blend ready, meaning it will continue to work as hydrogen blends are introduced into the gas grid.

*When used with the 8313 control.

More flexibility

Does the boiler have a minimum flow rate?

Due to the robust design of the 7000 FP heat exchanger, there is no minimum flow rate required and no special requirements for back-end protection.

Can I connect the boiler into an existing system?

If the existing heating system is a sealed type and not open vented, the 7000 FP can be connected very simply following normal hydraulic principles. If in doubt, send us a sketch of your proposal and we will check it for you.

I don’t want to change the existing system from open vented. What can be done?

If it is not practical to upgrade the system to a sealed pressurised type, a plate heat exchanger may be used to keep system separation and give protection to the boilers. Bosch has a range of plate heat exchangers sized for such applications.

What water treatment methods can be used?

Generally, we recommend following the water treatment guidance from the ICOM Water Treatment Guide or alternatively follow the guidance of VDI2035. For further guidance see the technical bulletin covering water treatment for boilers with aluminium heat exchangers.

What gas pressure is required?

The 7000 FP boilers can work within a gas pressure range of 17mbar to 25mbar.

Are the 7000 FP boilers ready for hydrogen blends?

The boilers are ready for hydrogen blends between 0% and 20%. They have been tested and certified in readiness for this potential change in our UK gas supplies.

Can the 7000 FP boilers be joined together for higher outputs?

Yes, the 7000 FP boilers have been designed to be easily cascaded together and can be purchased with either a left or right-sided hinges to aid service clearances. See the installation manual and flue guidance documents for typical layouts or get in touch for further advice.

Can I make up my own pipework to join boilers as a cascade?

Yes, you can make up your own pipework connection arrangements on site if these follow sound hydraulic principles. Alternatively, there are pre-made high quality cascade kits available for joining two boilers in common system arrangements, where time saving is the priority.

Are there any special conditions for common cascade flue systems?

Yes, Bosch has taken the decision to require CO detection with boiler interlock for any common cascade flue system where there is more than one boiler connected. With the increased popularity of cascaded boilers, we believe it is time to raise the bar on boiler room safety. CO detectors are now supplied as part of our cascade flue kits ready for on-site wiring, to make this transition simpler. For further information refer to the technical bulletin.
