About us

What we sell

Spare parts for burners and boilers: gas valves and coils, burner control units, flame sensors and detectors, ignition transformers, electrodes and cables, pressure switches, oil nozzles, actuators, fans. Parts by Honeywell, Siemens, Kromschröder, Danfoss, Dungs, Brahma, Riello and others, for domestic boilers and for industrial installations alike.

Why a catalogue, not a list

A spare part is rarely bought by name. It is bought by the number stamped on the old one, by the model of the appliance it came out of, or by a description of what it does when nothing is legible any more. A list of goods answers the first case and fails the other two.

So each part here carries its order number, the manufacturer's own designation, the numbers it replaces and the numbers that replace it, the appliances it fits, and its measured characteristics — pressure range, voltage, thread, response time. All of it is taken from manufacturer documentation and supplier data, and every value is traceable to the wording it came from. Nothing on a product page is invented.

If the number is unreadable

That is the normal case, not the exception. Rating plates burn, corrode and get painted over. Describe the appliance and what the part does, and the assistant on this site will narrow it down — it searches the same catalogue, by characteristics as well as by number. If it cannot, write to us: a photograph of the old part is usually enough.

Where we are

Based in London, shipping worldwide. Company details are on the legal notice.

Languages

The catalogue is kept in English and translated into the languages in the footer. Part numbers, manufacturer designations and measured values are never translated — a number means the same thing in every language, and changing its form would only break the search.

Trade customers

Service engineers and installers buy most of what leaves here. If you fit these parts for a living, write to us — regular buyers are invoiced rather than charged at checkout, and businesses in the EU with a VAT number are invoiced at 0% under the reverse charge.
