Office Heating

With business energy prices at eye-watering levels, more and more companies are looking for ways they can reduce their office energy consumption & bills.

Offices are a key feature of most businesses so it's no surprise that they are a big energy user. Government research 1 estimates that offices, along with retail, are the two largest sectors in terms of energy usage, accounting for 17% each.

Energy efficiency benefits the bottom line 

Working to reduce the energy your offices use is a great way to improve a company’s bottom line. For instance, for a company with a 5% profit margin over 3 years, a £5,600 a year saving from energy efficiency makes the same profit as £30,000 of extra sales 2.

Heating is a major focus 

Many businesses are doubling down on heating costs and it's easy to see why. A major government-backed study3 found that heating accounted for 41% of total non-domestic energy consumption.

 Ways to reduce office heating costs

Reducing your office heating bill needn't be complicated or costly. Below we provide some simple ways that you can trim your spending.

Choose an efficient form of heating 

There are four main fuels used in office heating systems 

  • Gas

  • Oil 

  • Electric 

  • Liquid petroleum gas (LPG). 

Gas is the most popular type of fuel in the UK. It is the cleanest of the fossil fuels, emitting half of the CO 2 emissions compared to oil. However, it still emits CO2 so it cannot be considered a ‘green’ method of heating your business. The same is true for oil which, in commercial settings, is more commonly used in the form of Gas Oil. LPG can convert a high percentage of energy into heat, but it still lags behind electric heaters.

Tansun’s infrared heaters typically convert 96% of energy into heat. An important added bonus is that electric heaters, if powered by renewable energy, open up the prospect of zero-emission during usage.

Don't overheat

Heating costs increase by around 8% for every 1° C increase so it's very important that you don't overheat your offices. The Carbon Trust reports 4 that the optimum operating temperature for an office is between 21 and 23°C so stick to this range unless there is a clear reason not to. But don't forget, you don't need to heat all areas equally. Corridors, storerooms and areas of physical activity can be set to lower temperatures.

Use controls

It's vital that your office heating system does not heat when areas are not occupied. The same also applies to times when they are not needed (e.g. during the summer months, weekends etc). It sounds obvious but make sure that your heating system includes controls that allow you to adjust according to these needs. Also, consider installing motion sensors so that heating is turned on only when people are present. We offer a  range of controls for our heaters, everything from remote controls and motion sensors to sophisticated thermostatic & time controls.

Reduce space volume 

If your office has high ceilings, adding a suspended ceiling is a really effective way of reducing the space you need to heat. Our Efficiency range of Infrared Heat Panels is perfect for fitting into ceilings.

Other considerations

Reducing emissions

Most offices are looking to reduce heating costs but also want to reduce their CO 2 emissions at the same time. There is a long way to go, 80% of heating in offices is still powered by fossil fuels such as gas & oil5. By contrast, switching to electric sources of office heating and coupling the switch with renewable energy tariffs provides the potential for emission-free heating.

Tansun infrared office heaters

Tansun has conducted extensive market research to understand the challenges of heating offices and has developed the ideal office heating solution.

Efficiency Radiant Heat Panel Series


Ideal for office environments and anywhere you are looking to replace central heating radiators, our radiant heating panels provide even heat distribution to gently warm people and objects before targeting the surrounding air. Three panel heaters have been developed by Tansun in different sizes to cater for numerous areas. The Efficiency  Series 600 (300W)900 (610W) and 1200 (785W), are extremely low wattage and ideal for reducing energy bills without sacrificing comfort. 

Why our infrared panel heaters are the best choice for office heating:

  • Flexible mounting - Our Efficiency Range of Panel Heaters can be wall or ceiling-mounted. When wall mounted, unlike traditional wet radiator systems, they don’t need to be fitted low down. The ability to ceiling-mounted can be a big advantage as they can be put out of the way and the installer does have to worry about pipework etc. Ceiling mounting also allows a uniform even heat spread in the office whereas with radiators this isn’t always possible as things may hinder this such as windows, electrics, or desk placements etc. leading to the sub-optimal placement of existing heating systems.
  • Instantaneous heat – the heaters provide comforting heat as soon as switched on. As rooms can be heated quickly and easily no energy is wasted providing heat to unoccupied areas.
  • Economical & efficient – with up to 98% of energy turned into heat electric heat panels are a great way to cut office heating bills. And the heat is efficiently dispersed - infrared waves directly heat areas so no heat is wasted.
  • Silent operation - no moving parts 
  • Fit & forget - requires no maintenance & comes with a 5 Year Warranty.
  • Discrete and unobtrusive - Can blend into any environment.
  • Controllable - As each panel is standalone, individual rooms can be heated as and when required.
  • Even heat distribution - Gently warms people and objects before targeting the surrounding air.
  • Safe & reliable.
  • Pair with controllers -  The heaters can be controlled by remote controllers such as the Tansun Digital Thermostat.
  • Easier and cheaper to install – often in office environments, pipework is required and objects are blocked for heating systems to be installed but Tansun infrared heaters overcome this problem and use high-quality materials, making the heaters robust and lightweight.
