De'Longhi Water Radiators: Lifetime Warranty & Easy Installation Guide 2026

When it comes to heating your home efficiently and stylishly, De'Longhi water radiators stand out for their durability and design. The entire range—including decorative panels, standard radiators, mixed models, and the innovative Air System—comes with a 15-year warranty. But here's the best part: by using De'Longhi's own connection kits, you can extend that coverage to a lifetime guarantee. Whether you're upgrading your home improvement setup or adding warmth to a new room, this guide walks you through everything you need to know.

Understanding the De'Longhi Lifetime Warranty

Every De'Longhi water radiator includes wall fixings in the box, but valves and fittings for your existing heating system are sold separately. To unlock the lifetime warranty on both the radiator and the accessory kit, you must install De'Longhi's own branded detentor and valve alongside the connection kit. This is a significant advantage, as it reflects the brand's confidence in its high-quality materials and long-term reliability. For more tools and materials to support your installation, explore our home improvement collection.

Choosing the Right Connection Kit

De'Longhi offers flexibility with its connection kits. You can opt for a kit with an angle detentor and a valve without a thermostatic head (which is thermostattable, allowing you to add the head later), or a complete kit that includes the thermostatic head from the start. This modular approach lets you tailor your heating control to your needs and budget. Pair your radiator with complementary lighting to create a cozy ambiance in any room.

Step-by-Step Installation Guide

What's in the Box for a Towel Warmer?

If you're installing a De'Longhi towel warmer (termoarredo), the package includes an air vent, wall fixings with adjustable spacers, screws, expansion plugs, and finishing caps. Everything you need for a secure mount is included, making it a straightforward home improvement project.

Mounting the Detentor and Valve

Start by removing the protective caps from the radiator ends. Apply the small air vent at the top (where there's a single threaded hole). At the bottom (where there are two holes, one on each side), attach the detentor and the valve—both are angled fittings. Disassemble each component to screw the connector first into the radiator body. Each connector has an O-ring gasket and should be tightened with a 13 mm hex key. The valve has a threaded section where the connector collar screws on; tighten it with a fork wrench or a parrot wrench.

All Your Options at a Glance

De'Longhi's connection kit range includes:

• Blister packs with an angle detentor and a thermostattable valve (no thermostatic head).
• Identical kits that also include the thermostatic head for immediate temperature control.

These kits are designed to work seamlessly with your existing heating system. While you're upgrading your space, consider adding wall decor or a stylish rug to complete the look of your newly heated room.
