Fireplace Efficiency - Guidance Notes
Install a Flueless Gas Fire instead of an Electric fire and you will benefit from 35% more heat and 60% less running costs.

ENERGY EFFICIENCY AND SAVING MONEY

  • Choice of Energy Supply:
    • There are many ways to provide secondary heating for your home. The choice depends on many factors that need to be decided before purchasing. You may be considering an electric fire or wood burner but did you know that gas is the cheapest form of energy. By choosing a high efficiency gas fire you can reduce your heating bills, reduce running costs and also benefit from more heat into your room.
    • When compared “like for like” gas is :
      • Over 70% cheaper than electric.
      • Over 90% cheaper than burning wood.
      • Over 95% cheaper than burning bio-ethanol.
  • Running Costs:
    • This is the cost of running the fire regardless of how much heat is generated into the room.
    • All types of appliances have a rated heat input in kW. The amount of energy you actually benefit from in the room depends on the energy efficiency rating of the fire. To reduce your energy bills you need to select an fireplace with a low cost energy supply and a high energy efficiency rating.
  • Examples:
    • Ex-1 : Standard Inset Gas fire v CVO Glamour HE Inset Fire
      • Standard 5kw open flame inset fire:
        • Running Cost = 22.5p/hour.
        • Heat in the Room = 1.25kw.
      • CVO 2kw Glamour Inset Fire
        • Running Cost = 9p/hour.
        • Heat in the Room = 1.50kw.
          • Result = 20% more heat in room, 60% less running costs.
    • Ex-2 : Standard Wall Mounted Gas fire v CVO HE Blade Fire
      • Standard 7kw open flame wall fire:
        • Running Cost = 27p/hour.
        • Heat in the Room = 1.75kw.
      • CVO 4.6kw Blade glass fronted fire:
        • Running Cost = 20.7p/hour.
        • Heat in the Room = 3.8kw.
          • Result = 117% more heat in room, 30% less running costs.
    • Ex-3 : 2kw Electric Fire v CVO Flueless Angel Gas Fire
      • 2kw Electric Fire:
        • Running Cost = 28p/hour.
        • Heat in the Room = 2.0kw.
      • 2.7kw Angel Flueless Gas Fire
        • Running Cost = 12p/hour.
        • Heat in the Room = 2.7kw.
          • Result = 35% more heat in room, 60% less running costs.

Its still OK if you dont need more heat - turn the fire down and save even more money on running costs. The choice of fire is critical. It is best to discuss your goals first with our sales team before choosing a fireplace. Call 01325-301020.

GAS IS THE CHEAPEST WAY TO HEAT YOUR HOME - ITS A FACT!

To compare the true cost of a gas fire you need to compare them with the same "input kw rating". This is your starting point. The table below summarises a few types of fires and compares the wasted money at 1kw. This is a true comparison using an average of current utility bills as stated at the bottom.

FIREPLACE TYPE and EFFICIENCY
Type of Appliance Emissions Efficiency Positives Negatives
Flueless Gas Fire Very Low 99.9% High Efficiency and low running costs An Air Vent is required in the room to add fresh air. This does not cause drafts! When a high quality vent is purchased [£50] and used drafts will not be noticed.
CVO Flueless have a beautiful open flame.
Low Running Costs [from 6p/hour]
From 2Kw to 3.5kw Heat Outputs Room must have a window.

90% SAP Energy Rating  
Great Carbon Index Score  
Any wall within the room.

Many Sizes and Finishes available.  
Bespoke Designs Possible.  
No Chimney is required.  

Bio-Ethanol Fire

(also called "gel fires")

Very Low 99.9% High Efficiency. Very High Running Costs [x 20 of a gas appliance with the same KW heat output rating]
Open Living Flame Health and Safety Issues over using, lighting and storing of the bio-ethanol.
Low Installation Costs.

The larger the flame then more moisture is given off causing condensation.

Many Design Styles - wall mounted, freestanding etc. Possible smells caused by poor quality fuel.
Bespoke Designs Possible. Ventilation in the room is required [window or air vent]
No Chimney is required.  

Open Flame Fire [Chimney]

Low to High - the addition of the false logs or pebbles can increase the CO and CO2 emissions. Typically from 30% to 70% Open Living Flame Fire A chimney or flue system is required.
Beautiful Flame Quality  
Variable install costs based on size and style chosen.  
Many different styles and size options available.  
Bespoke Designs are possible.  
High Efficiency Gas Fire [Glass Fronted/Chimney] Ideal for upgrading an old inefficient inset fire. Typically from 60% to 85% High Efficiency A standard chimney or flue liner system is required.
Inset and Hole in the Wall Versions available. Fully glass fronted appliance. The glass can get very hot. Safety issue with Children.
Easy to install in existing chimney. Bespoke Designs not possible.
Balanced Flue Gas Fire [Glass Front with Flue Pipes] These fires tend to be large and use fake logs and pebbles to spread out the flame. 70-85% High Efficiency A balanced flue chimney system is required which can be expensive.
Sizes available from 600mm up to 2000mm wide. Fully glass fronted. This can get very hot and can be a safety issue with Children.
  Bespoke Designs not possible.
  Cost of buying the fire and the installation is very high when compared to any other types of fireplace.
Electric Fire N/A N/A Easy to Install. Can look cheap with limited style options available.
Easy to Use. Includes a false flame created using using lights.
  There are many cheap imports from China available.
  High Running Costs. You need to Burn Gas, Oil or Other Fuels to create Electricity. There is only a tiny amount created in the UK by wind/water etc.
The fires below are not manufactured or supplied by CVO Fire. The following advice is given as guidance only.
Wood Burning Stove. Worse than a gas fire however the argument is that it is releasing the CO2 that is already stored in the tree. This is absorbed by new trees. What happens when the usage is faster than a tree can grow? 60-80% Many style choices. Mess! A lot of customers have started to replace stoves with gas fires. This is because of the issues over lighting, cleaning, running costs and storing large amounts of wood.
  Health! The particles given off by burning wood can cause serious health issues.
  Environment Very high emissions and trees being cut down faster than they can grow will only result in one thing.
  Cost! Wood prices are increasing and are set to continue to increase. Typical running cost for a wood burning stove are £600/year.
  Usage! Buying of logs or pellets can be expensive and there are issues over storage.
  Chimney: It will most likely need to be lined and will need to be swept at least every year this adds up to the £100 to the running costs.

In summary you need to decide what you are hoping to achieve from your fireplace installation based on your location and site specific requirements. It is strongly advised that you call our technical sales team to discuss your requirements.
