Worcester Bosch Boilers

Although both form part of your central heating system, combi boilers and system boilers operate in completely different ways.

Combi boilers are better for smaller property and system boilers are most suitable in medium sized properties.

With combi boilers, you have an unlimited amount of hot water you can use because the boiler draws water from the mains on demand. A system boiler requires a hot water cylinder to work – the cylinder heats and keeps warm which it later distribute to points where it’s needed around the house. So, with a system boiler, it’s possible to run out of hot water if you use too much water and you have not programmed the boiler via the control panel to heat more water.

Combi boilers were specifically designed to fit within smaller homes where there is little or no room for water storage tanks. It circumvents the need for water storage by heating up in real time and on demand the water it draws from the mains system.

A regular central heating boiler actually has two storage tanks – a cold water tank and a hot water tank, both of which require substantial room in your property.

They need these tanks because they’re designed to be able to distribute hot water around a home to radiators, taps, and showers within a drop in either pressure or temperature.

The prices shown on this and boiler description pages are indicative prices for simple installations. By simple, we mean that no significant piping or remedial work is needed to replace your old boiler and that your new boiler will be located in the same place in your home.

If that’s the case, you should consider the prices shown an accurate representation of likely costs. 95% of the installations we do in customers’ homes are simple installations and, on average, the price customers pay is within 5% either way of the price on our website.

There are nearly 1,000 boilers available right now to UK consumers – that’s a lot of choice for both homeowners and installers. So how do you start assessing them?

The PlumbProud quality score is our attempt to do just that. Since 2013, we have spoken with 10,000s people in their own homes about getting a new boiler. Over that time, we’ve really come to understand what’s important to you and we can measure how likely a boiler would be to satisfy you by comparing their technical statistics with what you want the most.

The factors considered in the PlumbProud score including the length of the warranty on offer, likely running costs, environmental impact, wider public perception of an individual manufacturer, and so on.

No boiler we’ve run through the PlumbProud test has scored 100% but quite a few have got close. We’d ask you to consider that the higher the rating, the closer a model is to being a perfect boiler.
