The Greenstar range of boilers was the first incarnation of Worcester’s successful range of top selling boilers.

They consist of a pretty reliable heat exchanger when serviced properly at yearly intervals.

We also recommend they have the burner gasket and ignition electrodes changed at 5 yearly intervals or sooner. If they fail a negative fan flue test which should be carried out a part of the servicing routine yearly.

But back to our main focus of this Article.

The main cause of of water leaking from the bottom left hand side of a Worcester Bosch Greenstar boiler.

Although there can be more than one place water may leak from a boiler. The most common reason is when the left hand hydraulic block on a Worcester greenstar boiler pin holes or has a hair line crack spraying a constant trickle of water.

On Rare occasions there can be a catastrophic failure of the part and cause flooding. Although I have only heard of rumours of this and never seen it in person.

What causes the hydraulic block to fail and leak.

This failure of the left hand hydro block tends to happen in boilers when they are approx 5 years old or older. The cause can be generally attributed to 2 main reasons.

1. Wear and Tear, unfortunately a boiler is like anything else in life. It will breakdown as it gets older and parts in the boiler at one or another will fail.

2. The other most common reason is the lack of a shock arrestor or mini Expansion fitted on the cold water pipe going into the boiler.

Why do I need a shock Arrester or expansion vessel fitted on Worcester Bosch Boiler?

Well in some instances you don’t need one but a lot of gas Combi boiler not just Worcester Bosch. Practically every other manufacturer aswell use a type fibre glass reinforced plastic to mould and manufacture parts.

And whilst this is a tried and trusted material.

If you have a water meter installed it is of the most importance that a shock arrestor or mini expansion is fitted.

The reasoning behind is simple, water have a device that stops water backflow back into the mains network from your pipework it is most typically called a non return valve.

So why is this a problem for Worcester and other makes of Gas boiler?

The problem Is that when water is heated it expands by around 4%

it Doesn’t take a lot of expansion but it canto add upto an extra 3/4 bar pressure in your boiler for a short amount of time.

This continual stress of water expansion can cause the part to fail.

What can I do to minimise the risk of failure.
