Among the most popular alternatives for central heating and hot water, the oil boiler is perfect for rural properties that do not have access to the mains gas grid. Oil fired boilers are available in a range of kW outputs and configurations, making them suitable for smaller homes and much larger installations. Modern oil boilers, whilst requiring an external oil storage tank, are exceptionally energy efficient and save a lot of fuel by heating up water on demand, all whilst keeping your running costs lower than a gas boiler equivalent. As well as internal units, oil boilers are available as an external option with a durable weatherproof casing to protect it from the elements and giving you more indoor space to utilise.
