• Heats like the sun
  Radiant heat passes through the air and heats solid objects making it highly efficient wherever it’s installed.
• Instant heat
  No need for expensive pre-heating, these heaters give heat instantly, cutting the cost of heating intermittently used areas.
• Low running costs
  Because only the intended occupants are heated, not the air around them, you only pay for the heat you really need, rather than a whole area, or the atmosphere.
• Silent running
  With no moving parts, the Dimplex heaters are silent when operating, making them perfect where noise would otherwise be a problem.
• Low capital cost
  By only heating chosen areas, capital costs can be reduced with fewer heaters when compared with other systems.

How does radiant heating work?

1. Radiant heaters use the oldest form of heating known to man. Just as the sun’s rays heat the earth, so our radiant heaters use this same method of heating objects (the earth, people, buildings etc) rather than the air between them for effective performance.

2. These radiant heaters transmit infra-red energy which is converted into heat when it is absorbed by objects which in turn then begins to warm the surrounding areas as surface temperatures rise.

3. Because the energy is only turned into heat as it comes into contact with solid objects, this heating technology can be used either indoors where building insulation would normally be a problem, or outdoors where localised people heating is desired. In this instance the heat provided is highly efficient as very little is lost into the atmosphere, unlike other methods of heating.

There are five types of radiant heaters in the Dimplex range.

Ruby sleeved element

Designed to offer a warm red glow, these short wave length elements operate at 2,200°C to provide a directional zone of heat.

Gold finish element

Fitted to the Vector range, these elements work at similar temperatures to the ruby sleeved elements but also boast a gold finish that improves energy transmission by up to 15%.

Ceramic

These ceramic encased aluminium elements operate over a longer wavelength with lower temperatures to provide a softer heat without the glow experienced with other element types.

Infra-red element

With fast heat-up and a warm glow, these quartz infra-red elements operate up to 1500 deg for instant, trouble-free performance.

Gold finish element

For extended performance, the quartz halogen element fitted to the OPH20 runs at 2,200 deg and offers 2kW performance with a gold finished lamp for 15% greater transmission.

Benefits over gas patio heaters

Whether it’s to provide a comfortable place to smoke outside, increase the number of covers with outside dining, or just to offer suitable outdoor heating for the garden, Dimplex all-weather outdoor heaters are the ideal solution. They’re simple to install, safe to use and one of the most effective solutions for outdoor heating currently available, with a number of benefits over gas patio heaters.

The heaters transmit harmless infra-red radiant energy, like the sun, that turns into heat only when it comes into contact with a solid object i.e. people. So you’re heating the atmosphere or having the heat blown away in the wind – unlike outdoor gas heaters.

The Dimplex range of electric outdoor heaters are easy to install and need no regular maintenance unlike gas patio heaters, which also have inconvenient and expensive gas bottles to change and store. These heaters really do provide heat at the flick of a switch – 365 days a year, making them the ideal hassle free, ‘fit and forget’, outdoor heating solution.

The Dimplex outdoor heating range are some of the most efficient outdoor heaters available and much kinder to the environment than a patio heater:

• They’re extremely efficient, providing comfortable warmth with only a low energy input. The 2kW OPH20 gives off heat comparable to a 12kW gas heater
• Heat loss is minimised with infra-red technology heating solid objects only
• No need to transport heavy gas bottles, so reducing carbon intensive distribution
• When linked to our PIR sensor the heater will switch off automatically, reducing running costs even further
• Running costs of only 10p-14p per hour†
• Can be linked to PIR sensor
• No regular maintenance – heating elements lasting up to 5000 hours
  
  

The instant directional heat can be felt straight away, with no waiting for the heater to warm-up. Even on a breezy day the heat will not be blown away and the heaters are water proof so even on rainy days, they can still be used.

Dimplex outdoor heaters can be permanently mounted on a wall or on an umbrella*, so cannot be knocked over accidentally. And because they are electric you don’t need to worry about poisonous carbon monoxide, or potentially explosive gas bottles stored on the premises.
