Here at the heat is on, we put the knowledge of what you need directly in your hands as the homeowner, so you needn’t ask or wait for information from your electrician. Here we give you complete expert guidance for this specific electric radiator — including details of any additional parts required — so you can ensure a smooth and successful installation when your tradesman arrives.

heat output

• Firstly, if you haven't already done so – use our heat calculator to work out your specific requirements for your room to ensure you are looking at the right size electric radiator – in terms of the Watts / Kilowatts heat output it gives.

design & material

• Pajak (meaning “Spider” in Polish) takes its name from the striking spider-like formation of exposed copper pipes.
• Manufactured from unpainted copper, designed to naturally age and develop a rich patina over time.
• The industrial, sculptural structure makes this radiator ideal for loft-style interiors and converted warehouse spaces.
• Supplied with integrated wooden hangers, adding warmth to the design while providing practical hanging space for hallways and corridors.
• Additionally, we have created a thorough and detailed technical guide on electric radiators, giving even more information and tips.

full range of sizes available

• In addition to the sizes we are displaying here on the heat is on, you can view the full range of 9 different sizes of PAJAK E here on the Terma website.
• We can process a special order for any size you wish to purchase if that size is not shown on our website.

control & functionality

• The Terma SIM Element has one fixed internal operating temperature of 65°C.
• Element will thermostatically operate to maintain this temperature.
• No Timer. Compatible with external Timer.
• No power button on element itself. Operable from the switch fused spur.
• Can be used in conjunction with a temperature control plate to allow you to retrospectively control the temperature on the element.

colour & finish

• This model is manufactured from natural copper and is not available in a standard painted finish.
• Over time, the copper surface darkens and matures, enhancing the character and giving the radiator a distinctive, lived-in aesthetic.

installation & features

• Element is pre fitted inside the radiator – located on the right-hand side (E8 connection). If you would like the heating element on the left-hand side (E1 connection), please contact us to place this as a special order. Think about where your electric supply will be so the wire has the shortest distance to travel.
