PRODUCT COMPARISON

We have compared Worcester boilers with Ideal, Baxi and Vaillant in the tables below. The tables are set out by boiler type and then property size.

We have listed boiler prices, guarantee periods, heat output, hot water flow rates and efficiencies. We have also included whether the boiler is a ‘compact’ model, but which we mean they will fit in a standard kitchen cupboard. These models are then compared against their UK competitors in our analysis of how Worcester boilers measure up against Baxi, Vaillant and Ideal.

We found that Worcester are great value in some categories and expensive for what they offered in others. Depending on the size and type of boiler you need, you may find that a Baxi, Vaillant or Ideal boiler actually gives a better package for the price compared to the Worcester boiler in that group.

Combi boiler comparison

Combi boilers

​A combination boiler is a single unit that provides heating and hot water to the home. In it provides instantaneous hot water direct from the cold mains. This is different from a traditional system which stores hot water in a tank in advance of use, i.e. a hot water cylinder is not required. Combi boilers are great for freeing up space but do not work well when water pressure is poor.

Combi boiler tables

Worcester combi boilers are presented here based on the typical size property they would serve. Find your property size and then compare the appropriate Worcester boiler with other popular manufacturers.

Worcester’s Greenstar Pro is in the middle price wise of the boilers in this category. It is a great value mid-range boiler with 94% efficiency, although it will not fit in a kitchen cupboard. If you are on a budget then Baxi and Ideal both offer much cheaper boilers with 4 and 7 year warranties. The Greenstar CDi compact in the Premium range is cheaper than its nearest competitors and better all-round value.

Heat only (regular) boiler comparison

Heat only (regular) boilers

A regular boiler provides heating directly to the radiators and works with a hot water cylinder to provide hot water. These are usually open-vented heating systems (they can be sealed), i.e. there is a Feed and Expansion tank in the loft. A direct replacement of a regular boiler is very cost effective, however it does limit the new boiler warranty to cover the heating only. The other components of the system, such as pumps, valves and the hot water cylinder are not covered and will be subject to on going maintenance and replacement liability.

Heat only (regular) boiler tables

Worcester regular boilers are presented here based on the typical size property they would serve. Find your property size and then compare the appropriate Worcester boiler with other popular manufacturers.

There is a very narrow range in price from the cheapest to the most expensive in this size of boiler. Vaillant offer the best value with upto 10 years on their ecoFIT and ecoTEC boilers.

System boiler comparison

System boilers

Like regular boilers, system boilers work with a hot water cylinder. Unlike regular boilers, the system is not open-vented, i.e. there are no tanks in the loft. In addition, all of the components that would normally be outside a regular boiler (pumps, valves etc) are integrated into the boiler. These are a modern version of the regular boiler and are often installed along side unvented hot water cylinders. They are great for larger properties with more than one bathroom, but only if the water pressure is good.
