Product Description

How efficient is the FS 42CDi?

This is a highly efficient boiler with an efficiency of 92% which makes this an ErP A-rated boiler that could help to lower your heating bills.

Is the output rating suitable for my home?

A 42 kW output rating means that this boiler is suited to large properties with over 20 radiators.

Are any other options available in the range?

If the 42CDi is too powerful for your home then there’s also a 30 kW model.

Is a regular boiler suitable for my home?

Regular boilers are typically found in period properties and need to be installed alongside feed and expansion tanks in the loft as well as a hot water cylinder. This means they take up a fair amount of space and need the appropriate pipework too. For this reason, it’s highly recommended to only consider a regular boiler if you already have one installed.

How long is the warranty period?

When installed by a Worcester accredited installer the FS 42CDi comes with a warranty of up to 7 years.

What are the key features of the FS 42CDi?

It is ideal for replacing an older floor standing boiler in the larger sized homes. It can be used with a wide range of accessories such as the Greenstore cylinders which allow stored hot water be rapidly filled up again and again.

As well as this it can be used with Greenskies solar panels – another great way to help save energy and cut your household bills down. The Greenstar CDI fs is a compact boiler that is able to fit underneath a standard kitchen worktop helping it to take less room up as well as be hidden away.

It has simple controls, knobs, and a temperature display making it easy to use.

How big is the FS 42CDi?

This boiler has been designed for compact wall-mounted installation with dimensions of 850 x 400 x 600mm (HxWxD).
