New and Replacement Oil Boilers
If your property is not connected to mains gas, an oil-fired boiler may provide
heating and hot water. A well-maintained system can last for many years.
However, frequent breakdowns, rising repair costs and poor performance may
indicate that replacement is needed.
At NCS Plumbing & Heating Specialists, we use decades of experience
to help you choose a suitable oil boiler. First, we assess the property.
We then compare system types, outputs and manufacturers.
We also install and replace domestic oil storage tanks.
Furthermore, we manage the process from assessment through to commissioning.

What Type of Oil Boiler Is Right for Me?
Modern condensing oil boilers are available in several formats.
The best option depends on property size, available space and hot-water demand.
Standard Oil Boiler
Conventional system
A standard oil boiler works with external controls and a hot-water cylinder.
In many homes, it also uses a feed cistern and loft storage tanks.
Stored hot water can supply several taps or showers at once.
Therefore, this arrangement suits homes with higher hot-water demand.
Supports multiple bathrooms
Suitable for high hot-water demand
Requires a hot-water cylinder
May require loft storage tanks
Most suitable for:
Larger households and properties that need substantial amounts of stored hot water.
Combination Oil Boiler
Combi system
A combination oil boiler provides heating and hot water on demand.
It is compact and does not usually need a separate cylinder or loft tank.
Water is heated when a hot tap or shower is used.
As a result, there is no stored hot-water supply to run out.
Hot water on demand
No separate cylinder required
Space-saving installation
Best where demand is more moderate
Most suitable for:
Smaller households, flats and bungalows. However, some modern combi boilers
may also suit larger properties.
