Description

Vokera 2573 Unica, Compact, Pro Combi Expansion Vessel

This Vokera Expansion Vessel is in the boiler to ensure that the pressure within the boiler remains reasonably stable. The most common problem customer?s encounter when a Vokera expansion vessel is faulty is the boiler pressure builds to 3 bar when switched on (approx. after 10 ? 15 minutes). At this point hot water starts to dribble through the 3 Bar Safety Valve (Prv) then outside via the discharge pipe.

When the boiler cools down the pressure in the boiler falls to 0 bar and will not start, this is because the expansion vessel couldn't control the pressure within the boiler. The customer will then refill the boiler back up using the filling loop normally located below the boiler. Once the correct pressure is reached (1 Bar normally) the boiler will start to work again.

Most Engineers Change The Pressure Relief Valve When Changing The Expansion Vessel 2573, Please Read Why Below.

Normally when this expansion vessel fails the pressure relief valve is constantly open ensuring the boiler doesn?t work above 3 bar pressure and because of this the pressure relief valve needs changing as well.

Debris from within the boiler gets trapped on the seat of the pressure relief valve which prevents the pressure relief valve from re-sealing thus allowing the boiler to loose pressure. If you check below we may have displayed the pressure relief valve you require, if so please add it to the basket if you feel you require one.

Further Information
This is an OEM Part

The term OEM stands for "Original Equipment Manufacturer" this part is an original part and was bought from the Original manufacturer of the part.

What does that really meanr a boiler manufacturer such as Wocester Bosch, Baxi, Glowworm etc.

Below is an example:

Gas Valves on most British Gas Boilers are made by Honeywell, Sit, White Rogers etc. This means that these manufacturers are the OEM for the Boiler Manufacturers, so as long as the original part is purchased (Honeywell, Sit, White Rogers) from the OEM it can be sold as an original OEM product.

OEM parts are also referred to as After Market Parts.
