TOKYO–LONDON CORRIDOR SIGNED: UK PM Keir Starmer & Japan PM Sanae Takaichi shake hands on bilateral clean-tech trade.

Hidden smart-meter drain: Legacy UK boilers waste £284/mo heating empty air volume. Japan's Setsuden stack—offshore wind + piezoelectric grids + self-throttling PTC—slashes winter draw up to 64%.

Cleared via UK–Japan ministerial clean-tech channels, BS 1363 hardware now operates from 9.8p–11.0p/hr at 50% allocation.

Reader Q&A

UK Delivery, Payment & Returns FAQ

Does high-wall unit Heatoor require an HVAC engineer to pipe refrigerant?
Zero piping required—Heatoor is a self-contained solid-state ceramic air curtain that mounts on two screws and plugs into a UK 3-pin socket.
Why does BaTiO₃ PTC draw fewer watts than wire-coil blowers?
Barium titanate ceramic self-regulates once airflow reaches equilibrium rather than cycling flat 2,000W red-hot elements.
Can everything be paid in GBP via Apple Pay or Klarna?
Yes—100% encrypted GBP checkout via Visa, Mastercard, Apple Pay, PayPal & Klarna with 2–4 working day tracked shipping.
What warranty & return window apply?
30-day home trial for a full refund plus a 24-month UK hardware replacement warranty.
