Vokera Vision Plus C Boiler

Offering flexibility in installation and performance, the Vokera Vision Plus C is a gas condensing combi boiler that comes in a range of sizes and outputs.

Vokera’s Vision Plus C Combi is a versatile gas boiler that runs on natural gas but can be converted to work on LPG with an optional kit. The 25C and 30C models are lightweight, have compact dimensions and come with a rear flue option to make them easy to install inside a kitchen cupboard. If you’re more interested in performance and want a combi boiler that delivers a high hot water flow rate, the 35C or 40C model could be the perfect choice for your home.    

How Much Does this Boiler Cost?

The Vokera Vision Plus C is available in 25kW, 30kW, 35kW and 40kW outputs and will cost you anything between £610 and £775. Keep in mind these prices relate to the boiler only and do not include installation costs, which vary depending on the installer or company you choose to install it and how much work is involved. We recommend you get a quote from local and national installers who cover your area of the UK to enable you to find the best price. 

How will I know if this Boiler is Suitable for My Home?

Combi or combination boilers are the most popular boiler type in the UK because they require minimal space and don’t need to be installed with extra water tanks or a cylinder. The Vokera Vision Plus C comes in a range of outputs to meet different heating and hot water demands but, regardless of size, may struggle to cope when you run two hot water taps at once. 

We suggest you consult a Gas Safe registered engineer to help you determine the correct boiler size/output for your home and requirements. If you have high hot water demands, your engineer may recommend you opt for a system or regular boiler rather than a combi. 

Is it a High Efficiency Boiler?

Yes. The Vokera Vision Plus C Combi is an A-rated boiler that’s fully compliant with the Energy-related Products Directive. If this combi boiler is installed with a weather compensation sensor or an OpenTherm control, such as BeSMART, it can achieve further efficiency. 

Does this Boiler have a Good Range of Controls and Features?

It has a simple to use embedded 7-day digital clock with three modes of operation and back-lit display to enable you to have complete control of heating times across the week. Vokera’s Vision Plus C also comes with OpenTherm inside, a built-in filling loop and a universal pipe layout. The 25C and 30C models are the most compact and come with rear and top flue options, and the 35C and 40C models have a new radial stainless steel heat exchanger and a wide modulation ratio of 1:8.

How long is the Warranty on this Boiler?

All four Vokera Vision Plus C Combi boiler models in the range come with a 7-year parts and labour warranty as standard.
