Turnkey solar heating. Cold-climate proven.

Evactube builds compact, prefab evacuated tube systems that add solar heat to your existing radiator — without replacing your boiler, without drilling, and without waiting for the landlord.

Proven at −40°C. Built for all European winters.

What we are building

A small, flat-to-wall solar unit that:

• Uses 2, 4, or 6 evacuated tubes — modular, same manifold, same controller
• Feeds a radiator or pre-heats your return line
• Includes an integrated buffer tank to store heat for the evening
• Runs on a factory-sealed glycol loop — no freezing, no maintenance
• Can be powered by a small PV panel — no electrical connection needed
• Mounts without drilling where possible — renter-friendly, removable

It does not replace your heating. It reduces how much you pay for it.

Who it is for

• Housing corporations with older, poorly insulated rental stock
• VvE and apartment buildings where façade changes need approval
• Municipalities running renter energy programmes
• Installers and distributors looking for a differentiated add-on product
• Monuments and heritage buildings that cannot replace glazing

Why Evactube

We have done this before. In 2005 we built the first containerised biodiesel factories and shipped them worldwide. We have deployed evacuated tube systems in Antarctica research stations at −40°C. We know cold-climate solar thermal, international sourcing, and B2B scale.

We are now applying that experience to heating — with a product designed for the European rental market.
