Why Panel Radiation?
Panel radiation is used to heat 80% of Western European homes and has been on the market for over 50 years. Each radiator is its own “zone,” allowing for individual room temperature control and creating an environment with comfortable radiant heat. Compared to baseboard heating, it takes up to 75 % less wall space, making it a more space-efficient heating option.


Why Purmo DiaNorm Panel Radiation?
Purmo DiaNorm has produced millions of high quality radiators and is considered top-of-the-line in Europe. With an attractive design, their high quality is synonymous with lasting value and the engineered, efficient heat transfer is economically sound. Purmo DiaNorm panel radiators generate comfortable heat at lower water temperatures than baseboard heating. Panel radiators can be piped with plastic “PEX” tubing that makes it much easier to install than copper. With DiaNorm you buy state-of-the-art technology.

The Material
Purmo DiaNorm Radiators are made of high quality 1.25 mm FePO1 steel. The finish is epoxy powder coating that is baked at 400°F. The Final Color is white to RAL 9010 that can easily be painted over with any color.

The Quality and Warranty
Purmo DiaNorm radiators are built to the highest quality standards and carry quality seals such as DIN, TÜV, EN, RAL, NF. The factory has been one of the first to receive ISO 9002 certification. If properly installed, Purmo DiaNorm radiators come with a 5 year limited warranty.

Bottom Tappings
Water connections are not exposed, but located at the bottom. If installed in one-pipe “series loop” installations, diverting valves can be supplied that will reduce installation time and the amount of materials used. A unique flow setter built into the thermostatic valve allows the installer to regulate the water flow through each radiator, eliminating the installation of additional fittings.

Temperature Control

An integral thermostatic radiator valve and a standard thermostatic head allow automatic and nonelectric adjustment of the water flow and temperature according to the temperature setting. Since every radiator has its own temperature control, you can decide what individual room temperature you would prefer.
