For installers

A home ready for low supply temperature. In an hour per unit.

Connect Rator to the existing pipes and let it balance itself. No demolition work, no return visits.

The dilemma

A low supply temperature fails on the radiators.

At a low supply temperature, old radiators give off too little heat. The home then gets colder instead of cheaper.

Underfloor heating solves that, but means breaking floors, drying time and a long lead time. For you: more planning and more visits per address.

The solution for installers

Plug-and-play on the existing connection.

Mount, connect, done. No training or certification needed.

Rator handles the hydronic balancing automatically. You do not have to set anything by hand.

No support burden: the controls are on the unit, residents have nothing to learn.

Why Rator

Less hassle per address.

Zero setup at handover

Install a few units and they tune themselves. You just walk away.

Standard, replaceable parts

The fan is field-replaceable and installation is reversible. No lock-in.

Fail-safe

If the electronics fail, passive heat simply keeps working.

Inside

Many standard parts, cleverly combined.

On the outside, a clean panel with simple controls. Inside, the parts do the work together. Many of them are standard items from any wholesaler or a handful of large suppliers. That makes maintenance simpler and extends the service life.

Frequently asked questions

Good to know beforehand.

What is needed for mounting?

Only the existing radiator connection. Mount it, connect it, and the unit balances itself — in under an hour.

Does it work with OpenTherm?

Yes. The Rator Bridge controls the heat source via OpenTherm. It works locally and without the resident's wifi.

What does automatic hydronic balancing mean?

Rator measures the water flow automatically and steers towards the most optimal return temperature in the system. Manual balancing is not needed.

What if a fan breaks?

The fan is a standard part that you replace on the spot. If the electronics fail completely, passive heat simply continues.
