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

This expansion vessel is a component for closed-loop heating systems. It is compatible with ACV Compact Condens 35, 55, and 65; ACV HeatMaster 71 and 101; and ACV Smart Line 85 and 130. The vessel maintains consistent pressure in the system by compensating for thermal expansion of water. This action protects boiler components from excessive stress and pressure.

Pressure protection	Protects boiler components from excessive stress and pressure
Primary function	Maintain consistent pressure in closed-loop heating systems
Thermal expansion compensation	Compensates for thermal expansion of water

Choosing and fitting

Expansion vessels are selected to match the boiler model and system volume. Before ordering a replacement, verify the boiler model nameplate and compare the part number. The vessel connects to the heating circuit via a connection point on the boiler; mounting position and orientation must follow the boiler installation manual. System pressure rating and pre-charge pressure of the replacement must match the original specification.

Signs of failure

Failure of an expansion vessel typically causes system pressure to rise uncontrollably or fluctuate during heating cycles. The boiler's pressure relief valve may vent water, or the system may lose pressure when cooled. A failed vessel may produce a hissing sound at the connection point or show signs of rust or corrosion on its surface.
