Nestor Martin Harmony 11 Oil Stove

Nestor Martin Harmony 11 Oil Stove

The Nestor Martin Harmony 11 Oil Stove provides dependable, continuous heating with the classic appearance and durability of a cast iron stove. Built for homeowners who want a reliable source of warmth throughout the day, it combines efficient oil-fired performance with straightforward operation and low maintenance requirements.

Unlike heating systems that repeatedly cycle on and off, the Harmony 11 runs continuously to maintain a comfortable and consistent room temperature while reducing noticeable fluctuations that can create cold spots and draughts. This makes it an excellent choice for living rooms, conservatories, workshops, and other spaces where steady background heat delivers the greatest comfort.

Nestor Martin Harmony 11 Oil Stove Efficient and economical heating

At the heart of the Harmony 11 sits Nestor Martin’s highly efficient vapourising oil burner, which optimises the mix of combustion air and fuel to achieve clean and effective combustion. This efficient burner design maximises heat output while helping to control fuel consumption.

The stove delivers a variable heat output between 2kW and 5kW, allowing you to adjust the warmth easily using a simple control dial. Whether you need gentle background heat during milder weather or increased warmth on colder days, the Harmony 11 adapts to changing conditions.

With fuel consumption ranging from just 0.15 litres per hour to 0.63 litres per hour, the stove supports economical day-to-day operation. Under typical usage, running costs remain surprisingly low, making it an attractive option for homeowners seeking an efficient alternative to more traditional heating systems.

Built from cast iron for lasting performance

The Harmony 11 uses cast iron construction to deliver a solid, timeless appearance alongside practical heating benefits. Cast iron retains heat more effectively than steel, allowing the stove to continue radiating warmth even after the burner output begins to reduce.

This heat retention creates a more comfortable living environment and helps deliver the steady, even heating that defines the Harmony range.

Its traditional styling also allows the stove to complement both period properties and modern homes, blending naturally into a wide variety of interior settings.

Nestor Martin Harmony 11 Oil Stove Reliable operation, even during power cuts

One of the Harmony 11’s key advantages is its ability to continue operating without electricity once you have lit the stove.

The stove features a convenient push-button electric ignition system that makes lighting simple. After ignition, the gravity-fed oil supply keeps the burner running without an electrical connection. During a power cut, the stove can continue providing heat, offering reassurance when other heating systems may become unavailable.

Because the Harmony 11 supports continuous operation, it maintains a more stable indoor temperature throughout the day and reduces the need to repeatedly heat a room from cold.

Straightforward installation and maintenance

The Harmony 11 measures 565mm high, 500mm wide, and 450mm deep, creating a compact footprint that suits a variety of installation projects. Its 83kg cast iron construction provides the durability expected from a premium appliance while remaining suitable for many fireplace openings and freestanding installations.

Installers should allow clearances of 250mm to combustible materials at the rear and 300mm at the sides. The stove features a top flue outlet with a centre position 108mm from the rear of the appliance, while the centre of the rear flue outlet sits 405mm from the base, helping installers plan accurate flue connections.

If you are planning a new installation, understanding the professional stove installation process will help you achieve safe positioning, correct flue design, and reliable long-term performance.

Maintenance remains simple thanks to the efficient vapourising burner, which keeps carbon deposits to a minimum during normal operation. Routine maintenance throughout the heating season involves using the integrated de-coking tool, while an annual service from a qualified engineer helps maintain safe and efficient performance.

The Nestor Martin Harmony 11 Oil Stove delivers dependable heating, economical operation, and robust construction for homeowners who value comfort and reliability. Its cast iron body, efficient vapourising burner, and continuous heating capability combine to provide comfortable warmth with minimal day-to-day intervention.
