Green Heat Module (Modular Plant Rooms)

Modular biomass Packaged Plant Rooms incorparating single or mutiple biomass boilers, integral fuel stores and even fossil fuel back up if required.

A 20year warranty is offered with the Hargassner UK Packed Plant Room as well as a 40year paint warranty and a 25 thermal and structural intergrity warranty. Another Industry First from Hargassner UK Ltd...

Where customers don’t have the internal space available for a biomass heating boiler and fuel store, or would prefer to have the plant room sited away from the main building, we offer a fully modular packaged plant room solution which houses both of these in a single unit.

Containerised Biomass


The Green Heat Module arrives at your site on the back of a lorry, as a 'Plug and Play' solution. The unit is fully-fitted out, and is simply linked direct to your existing heating distribution system via flow and return connections, or via a HIU (heat interface unit). Low Loss Headers can be introduced within the Module for multiple hydraulic ‘hook ups’.
The main benefits of this approach are faster installation and reduced business interruption. In addition, where a business may potentially move premises, it is possible to also move the container while still claiming the Renewable Heat Incentive at the same rate as when it was first commissioned.

The modules are secure, providing excellent protection against theft and
vandalism. There are also a number of aesthetic options to allow them to blend
into your environment. They can be pre-painted in a range of colours, clad in various materials or vinyl wrapped with imagery of your choice.


Total Warranty, Total Peace of Mind – for the Life of the RHI

The main concerns from a number of clients relates to the certainty of the RHI payments and boiler longevity. The RHI payments are linked to the boiler serial number.

If the boiler breaks down and is irreparable, then the on-going RHI payments are lost. This can be catastrophic if the boiler failure occurs early on in the life of the boiler and even worse still if the boiler is outside of the warranty period – which is normally less than 5 years.

If a re-submission of RHI is required it is likely that it will be at the new, and much reduced rates. This is because RHI payments are set to degress (for new comers to the scheme) at regular intervals.

Hargassner understands that these risks are significant, and for some clients, unacceptable. Therefore, Wood Energy Ltd provides a Total Warranty for our Green Heat Module containerised solutions. 

A Total Warranty for the whole Green Heat Module is included within the cost. These would typically include, but are not limited to;

  • Module has a 25yr thermal integrity warranty

  • Module has a 25yr structural integrity warranty

  • Module has a 20yr boiler warranty*

  • Module has a 40yr paint coating warranty. Module paint coating does not require annual inspection and is a maintenance free product of up to 40 years Inland and 30 years for a Coastal application / installation.

  • Module ‘Total Coating’ Warranty goes direct to the building owner, and is fully transferable should the Module be sold to another party.

    * The Total Warranty is only available if the client enters into a Hargassner UK Ltd Service & Maintenance Contract at time of order.The Total Warranty is only available for Green Heat Module solutions.
