These are perfectly working spiral design heaters we've had in our loft powered by a gas boiler system. Bought as new and installed in 2017. They functioned perfectly and had a two year grace period while e renovation works took place for a couple of years (20222-2024). They resumed working again from early 2024 and were removed in December 2025 as part of a new interior decoration plan. We've had them professionally cleaned yet now are stored in one of our garages. This is ideal for a loft or even a business setting, eg Cafe, Store. Please note that the sale is for the bundle of four units, thus, the total price announced is for the four units together. Ideally picked up or a moving company is arranged to transport these items.
