What does the shop sell?

Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

How large is the catalogue?

Over 100,000 part numbers from every major manufacturer, brought into one structure so that parts from different brands can be compared and replaced.

Can I find a part by its number?

Yes. The order number, the manufacturer model and any supplier code all lead to the same part, so a number from an old invoice or a nameplate is enough.

What if the part is discontinued?

The catalogue records what the manufacturer replaced it with, and which parts from other brands do the same job — together with the conditions that apply.

The company is based in London and ships across the United Kingdom, Europe and the rest of the world.

Is the shop open yet?

The catalogue is being assembled now. The shop opens as soon as it is ready.

Description

The Danfoss Oil preheater FPHE5 (SKU 030N6004) is a component for oil burners that fire heavier fuel grades. It delivers a flow rate of 2.022 GPH and is designed for fuels with a viscosity up to 10 cst. It includes a built-in le valve and is equipped with a thermal fuse or thermostat as a safety feature. Its function is to warm the fuel oil before it reaches the nozzle, reducing viscosity to ensure proper atomisation and stable combustion.

Further details

Application	oil burner fuel systems for heavier fuel grades
Design features	max temperature limits, improved atomization, high average burner efficiency
Installation Location	between oil tank and pump, or integrated into pump assembly
Key parameters for selection	heating power (wattage), supply voltage, thread size of hydraulic connections, mounting arrangement

Choosing and fitting

When selecting a replacement oil preheater of this kind, the key parameters to match are heating power (wattage), supply voltage, and the thread size of the hydraulic connections. The mounting arrangement must also match the burner chassis or pump housing. Always verify the existing unit's electrical rating and port dimensions against the burner technical data sheet; an incorrectly matched preheater can prolong the warm-up phase or fail to reach the required oil temperature.

Signs of failure

When a preheater of this kind fails to sufficiently warm the fuel, heavier oils do not break into a fine spray, causing incomplete combustion, soot formation, and an unstable flame. The warm-up phase may also become prolonged, or the oil may never reach the required temperature.
