The Types of oil boilers available is quite similar to the current range of gas boilers available, with the main difference being the fuel needed.

Heat Only/Regular Oil Boilers

Regular boilers are quite simply single boiler units, they do not incorporate a circulation pump, expansion vessel, safety valve or associated components. They are the most popular oil boiler on the market today and will efficiently cover both space heating and hot water requirements. A hot water storage tank/cylinder will be required with this boiler type. Regular oil boilers are particularly suited to open vent heating systems.

Combination Oil Boilers

Combination oil boilers are ideal for small property’s that have a low demand for hot water. They will provide heat for space heating requirements while also offering hot water on demand. Because this boiler type offers instantaneous hot water direct from the boiler there is no need for a hot water storage tank/cylinder. This offers a greater level of efficiency as you only pay for the water used. However the hot water flow rate can be quite slow, so this type of oil boiler is not suited to larger homes.

System Oil Boilers

System oil boilers come as purpose-built unit housing the main components of a heating system. The circulation pump, expansion vessel, and safety valve are the 3 main components a system boiler will house. They offer a quicker install time along with a neater installation. They are ideal for both space heating and hot water requirements.
