Who is Worcester Bosch?

Credit: Worcester Bosch

Worcester Bosch was established in 1962 in Worcester in what was then a thriving post-war Britain – where innovation and opportunity was abundant.

They initially focused their attention on building the best oil-fired central heating systems before eventually developing their own combi-boiler in 1971.

They now have over 2,000 employees, a network of over 300 service engineers, and they serve tens of thousands of customers throughout the UK.

Today, they have over fifty years of boiler development experience and they are even trusted by Her Majesty The Queen to heat the Sandringham Estate!

They are committed to environmental sustainability and they work to a comprehensive environmental policy.

They’re also the company behind the Robert Bosch Foundation which has spent £757 million on improving social initiatives. 

What is a combi boiler?

A combi-boiler heats water as it passes through the boiler directly from your mains supply.

When you turn on the hot tap, the internal gas burner is ignited and a heat exchanger heats up the water – meaning you get hot water almost instantly. 

It’s the same for your heating – the water is heated up by your combi boiler and then it’s piped through to your radiators as soon as you turn it on.

Combi-boilers are cost-effective and energy-efficient. What’s more, they work particularly well for smaller properties as they take up very little space.

They can be stored within your kitchen cabinet units or in a utility room – and you don’t need a loft for a water storage tank.

They are usually cheaper to install as you don’t need to plumb pipes up to your loft as you would with a regular boiler, and, as there’s no pipework in the loft, you eliminate the worry of them freezing over in cold weather.

Key combi boiler stats

When you’re deciding on which combi-boiler to go for, you’ll need to consider a few facts when coming to your judgement.

To make sure you are choosing the best boiler for your property size and needs, you should look at the flow rate of the boiler, its output, and its energy efficiency

Combi boiler flow rate

A boiler’s flow rate represents how many litres of hot water your boiler can heat and distribute in one minute.

This is determined by the amount of water provided by the mains supply and the capacity of your boiler to heat it.

The more powerful a boiler is, the quicker it will be able to provide you with hot water.

Flow rate is also entirely dependent on the amount of water entering your property from the mains supply as this is the maximum amount you can get.

If your boiler has a flow rate of 14 litres per minute, but the mains only allows you 10 litres, your maximum amount will still be 10 litres.

Combi boiler output

Boiler output refers to how much energy your boiler uses when it’s working, and it’s important to know, as the output rate tells you how much your boiler will cost to run.

To work out how much it will be, you multiply the output by the price of a unit of gas. 

For example, if you have a boiler with an output of up to 27kW and the price of a unit of gas is 4p, each hour the boiler is switched on will cost you 27 x 4p – which equals £1.08. 

You need to choose the right amount of ‘output’ for the size of your home and how much hot water you will need.

The higher the amount required, the higher the output needs to be.

For medium sized homes with 3 or 4 bedrooms and up to 15 radiators, a 28-34kW boiler is usually recommended.

Combi boiler energy efficiency rating

Boiler efficiency refers to the percentage of energy used by the boiler to do its two jobs correctly – to heat your home and to provide you with hot water.

When a boiler is working, a percentage of energy used goes to heat up the water and a smaller amount of energy is used by the boiler itself for non-productive internal functioning – this percentage is referred to as ‘lost’ energy.

For example, if a modern boiler is 94% efficient, only 6% of energy is ‘lost’ as the boiler runs itself.

An old boiler may only have 60% efficiency – meaning 40% of the energy is ‘lost’ so you will pay more to heat your home as it takes more energy.

Like all modern domestic appliances, boilers have efficiency ratings of A to G – with A being the most effective at 90% or over.

Credit: Worcester Bosch

All Worcester Bosch boilers come with either a 6, 10- or 12-year guarantee, depending on the specific boiler. 

A guarantee is free and it means that the cost of repairs is covered for the specified length of time in case things go wrong. Worcester Bosch also offers a complimentary call out visit if your boiler develops a fault providing you can prove you get your boiler serviced yearly. 

Here are some recent Trustpilot reviews which refer to the customer after-sales service:

I am happy to report that within 10 minutes of my review I received my guarantee in email. Excellent service but just a pity I had to complain before I got what should have been sent 10 months ago. But thank you Worcester Bosch. You responded very quickly and have restored my faith in your company.’

This A-star rated boiler is a highly reliable system for large properties where there is a high demand for hot water and heating and when only the best will suffice.

Featuring a high gloss finish – available in both black or white – and a digital, full colour control panel with intuitive menu structure, the thermostat can be linked to your smartphone for control anywhere.

It also includes the first Greenstar intelligent filing system which makes sure the boiler maintains optimum pressure without the need to operate a filling link. This reduces the risk of callouts should something go wrong.

This boiler is 780mm x 440mm x 365mm in size – and presents as a top of the range boiler for semi-detached or detached homes of 3 bathrooms or more.
