Keston oil boilers vs gas
Keston offers both oil and gas boilers, each with distinct advantages and considerations.
Keston Oil Boilers
Advantages:
- Efficiency: Modern oil boilers are highly efficient and can achieve similar efficiency ratings to gas boilers, often around 90% or higher.
- Availability: Oil boilers are ideal for properties not connected to the gas grid, making them a viable option in rural areas.
- Cost of Fuel: In some regions, oil can be cheaper than gas, though this varies by location and market conditions.
Disadvantages:
- Storage: Requires a large oil tank for fuel storage, which can be an issue for properties with limited space.
- Environmental Impact: Oil is a fossil fuel, and its combustion emits more CO2 compared to gas, making it less environmentally friendly.
- Maintenance: Oil boilers generally require more frequent maintenance than gas boilers due to the nature of the fuel and the potential for soot build-up.
Keston Gas Boilers
Advantages:
- Efficiency: Gas boilers are known for their high efficiency, with many models achieving efficiency ratings above 90%.
- Convenience: Gas is supplied directly through pipelines, eliminating the need for fuel storage tanks and reducing the hassle of refuelling.
- Environmental Impact: Natural gas burns cleaner than oil, producing lower CO2 emissions and fewer pollutants.
- Maintenance: Gas boilers typically require less maintenance compared to oil boilers, as they are less prone to soot and build-up.
Disadvantages:
- Availability: Gas boilers require access to the gas grid, which may not be available in some rural or remote areas.
- Fuel Cost: In some regions, the cost of gas can be higher than oil, though this can vary.
Overall Comparison
- Efficiency: Both types can be highly efficient, but gas boilers often have lower emissions and can be easier to maintain.
- Fuel Supply: Gas boilers offer the convenience of a continuous supply through pipelines, while oil boilers require a physical tank and regular refuelling.
- Environmental Impact: Gas boilers are generally considered more environmentally friendly due to lower emissions compared to oil boilers.
- Maintenance and Running Costs: Gas boilers usually have lower maintenance costs and potentially lower running costs, depending on fuel prices.
