HydroTop™ gives architects and retrofit coordinators a reliable, specification-ready solution for properties where conventional heat pump placement is not viable.
For architects and retrofit coordinators working on domestic retrofit, the heat pump external unit is a persistent design problem. On constrained sites, conservation area properties and terraced stock, finding a compliant location for an external unit can cause significant design iteration, or result in heat pump being excluded from the specification entirely.
Specifying HydroTop™ from the outset removes this constraint. With the unit housed within the roof void, the external design challenge disappears, and with it, the risk of late-stage redesign or value engineering.
Designed to meet Class C of the GPDO. In most cases no planning application is required, including many conservation area settings.
The low-profile aluminium cap projects no more than 150mm above the roof surface. Cap colour can be specified to match the surrounding roof covering.
Full technical specification documents, installation drawings and regulatory compliance information available to support design submissions.
Designed to support compliant delivery under PAS2035. We work with retrofit coordinators to provide the documentation required at each RIBA or retrofit stage.
Compatible with all major heat pump manufacturers up to 10kW, no constraint on the heat pump specification or supply chain.
We have experience supporting specifications in sensitive planning contexts and can provide technical input to support pre-application discussions.
We offer CPD-accredited technical presentations on HydroTop™ for architectural practices and retrofit coordinator teams, covering the product, the regulatory context, specification guidance and case studies.
We also provide direct technical support for individual projects, including specification review, planning submission support and liaison with our installation network.
If you are working on a project where conventional heat pump placement is proving problematic, get in touch. We can usually provide an initial feasibility view quickly and without obligation.
