Heat Logs vs Firewood Logs

Heat Logs vs Firewood Logs

18 September 2023

With the sunny days behind us, many of us are looking at heat logs as the new cost-effective alternative to ordinary logs.

Woodlets Briquettes and Roastie-Toasties – are good for your fireplace, your stove, your pocket – and the environment. They burn hotter, cleaner, are cheaper to buy and are much easier to store and handle than logs.

Change is underway in the UK today as customers wake up to the benefits of briquettes (the new buzzword for heat logs). Once you have tried them you will never go back to burning logs. And best of all, you get more heat for your money.

Today, wood-burning stoves are more efficient than ever – making it easier to heat your home. But be sure to keep an eye on what you’re putting in them – the heat you achieve will depend on the quality of log you are using.

With the cost of living rising, you want to take full advantage of heat efficiency by getting the most heat from your wood burner – or open fire – as you possibly can.

Briquettes have a very high heat output which keeps your house warm in winter.

Use our handy guide to steer you through the different options available to you and your wood-burning stove.

What are Heat Logs?

Heat Logs, or Briquettes, are dense, compacted blocks of wood that serve as a cleaner, more efficient, and environmentally friendly alternative to traditional firewood. Made from a blend of wood chips, wood shavings, and other wood materials, these briquettes offer a smart solution to make use of wood by-products that might otherwise be discarded. They are produced by compressing these materials under high pressure, all without using any additives or binders.

Are they worth it?

Is it worth buying heat logs over traditional logs? Although firewood logs are cheaper initially, it doesn’t mean that they are more cost-effective long-term. In fact, heat logs have a much higher calorific value than firewood logs, meaning that they release a larger amount of heat when completely burnt.

Additionally, briquettes burn longer and hotter, delivering a consistent and steady source of heat. This efficiency means fewer interruptions to refuel your fire, making your heating experience more enjoyable and less cumbersome.

Woodlets Briquettes and Roastie-Toasties burn 20% hotter than kiln-dried wood. They burn at least twice as hot due to their high calorific value (17.3 MJ/kg) and low moisture content – less than 10%.

Which logs give out the most heat?

To get the most heat possible out of your stove or fireplace, you should always buy your briquettes from a reliable retailer. Make sure they are accredited with the Ready To Burn badge and are Clean Air Act compliant. It is law in the UK today to use smokeless, dry fuel.

Dry wood not only produces less smoke and air pollution but also provides more heat, more efficiently, than wood that contains a high level of moisture.

Comprising 100% UK timber, our briquettes are not just environmentally friendly, but they’re also Clean Air Act compliant. With a high-heat output and ultra-low emissions, they’re the smarter, greener way to keep warm.

Are they better than KILN-DRIED logs?

Traditional firewood burns much quicker than briquettes. As a result, your heat will disappear up the chimney. Make sure you use a long-burning fuel. That way, you will be tending to the fire less and using less fuel!

Heat logs are much easier to light than firewood – they burn more slowly and your fire will need less attention.
