Central Heating and Boilers

Home heating systems can seem complex, but the basics aren't too difficult to understand. Here you'll find a few answers to some common questions, as well as an insight into some of the ways a Worcester boiler uses advanced technology to do more than simply heat your home.

How do I decide which type of condensing boiler best suits my needs?

There are three different types of high efficiency condensing boiler: combi, system and regular. Regular boilers are also sometimes referred to as traditional or conventional boilers - all effectively mean the same thing.

Each of the three types of boiler delivers all the benefits of high efficiency technology, but which one you choose will depend on several factors, including your property, your lifestyle and the professional advice given by one of our advisers.


Relax.
Finding the right boiler isn't as hard as you might think.

Here are a few examples and guidelines to think about and help you identify the type of condensing boiler most likely suited to your needs.

Boiler Examples

How a condensing regular system boiler fits into your home.

Low Pressure Hot Water Cylinder

What is a regular boiler?

This typically forms part of a conventional heating system, and is linked to a series of water tanks that feed the boiler and radiators. Storing hot water is key to this system, so unlike a combi, a plentiful supply of hot water is always available. Space in the loft and airing cupboard is required for tanks.

All Greenstar regular boilers can be used with a Worcester Greenskies Solar water heating system to provide hot water for your home. Depending on the positioning of the Solar water heating panels they could provide between 50-70% of your annual hot water free of charge from a sustainable source of energy.

What is a system boiler?

Like a regular system, this uses stored hot water. But because the water is pumped from the boiler straight to the radiators and hot water tank, it's a faster, more economical system. What's more, many of the components of the system are built-in, making it easier, quicker and more affordable to install.

Combi Boiler

What is a combi boiler?

Combi is short for 'combination'. It refers to the way this type of system serves as both a central heating boiler and a hot water heater. That means there's no need for a water tank as hot water is provided on demand. As well as saving the space normally taken up by a water tank (in the loft or airing cupboard), a combi boiler saves on hot water costs as well as giving you hot water at mains pressure.
