Product Descriptions

Both boilers are combi systems, which means that they are both capable of delivering hot-water and heating all through one compact unit. Here’s a brief description of both boilers:

Worcester Bosch Greenstar 30i

Designed with installer feedback in mind, this boiler could heat your home effectively without using excessive energy. With a user-friendly control panel and a condensate siphon to help prevent pipe freezing in the winter, this boiler could provide you with easy to use central heating as well as peace of mind. It’s 10.8l/min flow rate means that you could access the hot-water you need on demand without having to worry about running out as the water is heated directly from the mains.

Ideal Logic+ C30

With fully modulating operation, you could provide your home with the heating that it needs, as this boiler has the potential to operate at lower outputs to help save energy. Its compact cupboard fit could allow you to save space in your home and its low lift weight could make installation quick and easy; its also built with boiler frost protection. The C30 is endorsed by the Energy Saving Trust and comes with a standard 7-year manufacturer-backed warranty (Help-Link could extend this to 10 years at the point of sale) to give you added peace of mind[5].

Prices of products

On average the Worcester Bosch 30i could cost approximately £955 (exclusive of installation costs), whilst an Ideal Logic+ C30 could cost around £825 (boiler only, excluding installation).

The cost of complete installation in both boilers’ cases will typically depend on the complexity of the installation. Every household is different, so each home will have different parts and labour requirements; for example, some properties may require scaffolding or pipework modification, which will come at an extra cost.
