Want a heat pump but struggling to find the space?

You are not alone. Millions of UK homes face the same challenge. HydroTop™ was designed specifically to solve it.

Sound familiar?

The problems most homeowners face.

Heat pumps are the future of home heating, but for a huge number of UK properties, installing one has felt impossible. Not because the technology doesn't work, but because there's simply nowhere to put the external unit.

If any of these sound familiar, HydroTop™ may be the answer you've been looking for.

No external space

You've been told there's no suitable wall or garden space for an external heat pump unit.

Noise concerns

You're worried about the noise a heat pump would generate for you or your neighbours.

Planning restrictions

You live in a conservation area or a terraced property where an external unit isn't permitted.

Aesthetic concerns

You don't want a large external unit dominating the front or rear of your home.

Surveyor said no

A heat pump installer has already visited and told you a conventional installation isn't viable.

Terrace or mid-terrace

Your property type makes conventional external unit placement particularly difficult.

How HydroTop™ Helps

The heat pump that disappears into your roof.

HydroTop™ is a roof-integrated casement system that houses your air-source heat pump within the roof void of your home. The only visible external element is a low-profile aluminium cap sitting no more than 150mm above the roofline, barely noticeable, and in most cases requiring no planning permission.

The heat pump unit sits inside your loft space, protected from the elements and accessible for servicing without anyone needing to go outside. No noise disturbance. No visual impact. No compromise on your garden or external space.

HydroTop™ is compatible with all major heat pump manufacturers, so you get the benefit of a roof-integrated installation without being tied to a single brand or product.

Key Benefits

Virtually invisible

The low-profile cap sits flush with your roof. Neighbours and passers-by won't know it's there.

Permitted Development in most cases

Designed to meet Class C of the GPDO. In most cases no planning application is required.

Silent operation

With the unit housed inside the roof, there's no external noise disturbance to you or your neighbours.

Serviced from inside

All maintenance is carried out from within the loft. No outdoor access required, whatever the weather.
