Energy Efficient Heaters

At National Heater Shops, we have a great range of energy efficient heaters for domestic, commercial or industrial use.

Stay Warm In Winter With An Energy Efficient Heater

Right now, homes and businesses need the best heaters that are both energy efficient and money saving. Commercial electric consumption currently costs around £0.50 per kw/h, and domestic electric consumption is also seeing a rise in price. As it stands, the operating cost of central heating radiators, air conditioning units, and electric fan heaters will put many people under pressure during a cold spell. Butane, kerosene, propane, and heating oil burning space heaters and now represent the most energy efficient and economical solutions for keeping warm.

Types Of Energy Efficient Heaters

There are many different kinds of energy efficient heaters available, each with their ideal uses. Whether you are heating a room, warehouse, marquee, shop or outdoor area - there’s plenty of options available.

Infrared Heaters

Electric infrared heaters are reliable, robust and perfect for spot heating small spaces and outdoor areas.
We offer both electric models and diesel infrared heaters, which allow for more versatility. They create a warm, cosy environment that benefits contractors, staff, customers and stock. Diesel infrared heaters should be used in well-ventilated spaces due to their power supply.

Gas Space Heaters

Gas space heaters do not spread warmth through convection. They burn propane or butane gas which enters through an intake duct and is lit by pilot light. The flame then warms up radiant tubing or refractory materials. 

These liquefied petroleum gas (LPG) heaters are economical, efficient and practical as they do not spread warmth through convection. Like diesel infrared heaters, they are best used in well-ventilated areas due to the moisture and carbon monoxide they produce. Liquefied petroleum gas is a clean-burning fuel. While it is a fossil fuel and not entirely environmentally friendly, it does produce fewer carbon emissions than oil.

Direct & Indirect Heaters

A direct fired space heater provides a cost-effective way of heating outdoor and well-ventiled industrial areas with plenty of fresh air. The warm air that they circulate passes an open flame, meaning they are 100% efficient, but the heat they produce contains both fumes and moisture. 

On the contrary, an indirect fired space heater produces clean, fume-free and dry warm air, so they can be used for heating halls, marquees, farmhouses and a range of other indoors safely. They are fuelled using diesel, heating oil, paraffin or kerosene. They can be placed outside the area you want to heat and have the warm air ducted inside. Alternatively, the unit can be placed indoors and have a flue exhaust the fumes outside.

Cabinet Heaters

Our selection of cabinet heaters feature stainless steel combustion chambers, heat exchangers and internal fans. They are standing warm air heaters, encased in large metal enclosures. These heaters offer large volumes of clean warm air, to heat large industrial spaces safely and effectively. They require a flue to be set up through a roof or external wall, to vent exhaust fumes outside.

Waste Oil Burners

A waste oil burner burns a wide range of oil-based fuels including heavier viscosity that aren’t compatible with conventional heaters. Waste oil burners can be fuelled using engine oil, gearbox oil, vegetable oil, diesel oil, 35-sec heating oil and other types of used oil, and bio-fuels such as rapeseed oil. 

These heaters are an excellent option for heating large spaces using waste oil, providing a permit is obtained under Schedule 13A of the Environmental Permitting Regulations 2010, which costs for the application and an annual fee.

Are Electric Heaters Energy Efficient?

Electric heaters are considered to be 100% energy efficient, as they convert all energy consumed into heat. Whilst electric heaters aren’t always the cheapest method of heating, their energy efficient output makes them a desirable addition to spaces that need a fast, easy heating solution.
