About Castle Heaters
Choosing a heater type
Infrared heaters come wall-mounted or freestanding, and some are built for outdoor use, which makes them a fit for patios and garden rooms. They give targeted warmth and run silently. For indoor rooms, the alternatives are WiFi convection heaters and smart panel models. Many work with Alexa and Google, so you can adjust them by voice or app.
Spares and support
Castle Heaters also sells parts for its own products, including remote controls, replacement infrared bulbs and heating tubes. That helps keep an older heater going. Each item comes with a 12-month warranty.
Phone and email support run Monday to Friday, 7:30am to 4pm, except bank holidays.
Ordering and collection
Delivery is UK only, and you can collect instead from the Knowsley address. Returns generally need the product unused and in its original packaging, within the stated window; check the exact terms on the website before buying.
Payment is by Visa, Mastercard or PayPal. Students can verify through UNiDAYS or SheerID for a discount, and NHS staff and Blue Light cardholders have their own scheme.
