What is Zonal Heating?

Zonal heating, an efficient way to manage your home’s warmth, involves heating only the rooms you use to the desired temperature at a given time. Imagine it’s a chilly evening; instead of warming the entire house, you can save energy and money by heating just the space you’re using.

Onyx Stoves and Fires: Cost-Effective Luxury

Calculating the running costs of your Onyx appliance is easy using the following formulas:

Appliance input (kW) x Time in hours (h) = Energy used (kWh)

Energy used (kWh) x Cost per kWh (£) = Cost of energy used (£)

We’ve prepared a handy guide with examples to demonstrate just how little it costs when using our products for zonal heating.

Real Savings with Onyx

Onyx’s high-efficiency gas fires, like the sleek and powerful Avanti 65 Conventional Flue gas fire, are designed with advanced gas burner systems to deliver stunning flame visuals whilst minimising energy usage. With an impressive 4.5kW heat output, it costs approximately 87p2 for four hours of localised heat. In comparison, an hour of high continuous heating is just 39p.

Onyx electric stoves and fires, such as the stunning Fusion 150RW electric fire, combine realistic visuals powered by authentic flame technology, with innovative energy saving features. Enjoy up to 2.0kW of thermostatically maintained heating with flame visuals, for just 99p3 for four hours, or a minimal 25p for an hour of low heat. Opting to enjoy just the ambience of the Chromalight® Plus LED systems and glowing Birch Log-effect without the heat, costs as little as 4p for four hours.

Why Choose an Onyx stove or fire for Zonal Heating?

Whether you already own an Onyx electric or gas stove or fire, or are considering one, utilising one of these high-performing and efficient gas or electric log burners as a source of zonal heating could save you energy.

Onyx appliances are designed for maximum efficiency, incorporating advanced energy-saving systems and technologies. Our gas stoves and fires feature cutting-edge burner technology, while our electric models boast the latest Ecodesign compliant features, ensuring high efficiency at low running costs.

Thermostatic Heating

Control your Onyx stove or fire with ease using a remote control. Many models even feature programmable thermostatic heating, allowing you to set your desired temperature and let the fire do the rest. Some models of electric fires even allow all the functionality of the remote control from a smartphone app. Your Onyx stove or fire will intelligently manage heat output to reach and maintain the set room temperature in the most energy efficient way possible.

Open Window Detection

Our electric stoves and fires come with a feature that automatically turns off the heat if it detects a sudden temperature drop, like an open window, saving energy effectively. Designed to minimise wasted energy, all that’s needed to resume the heat is to close the window or simply press the button on the remote.

No Chimney, No Worries

There are still options for enjoying a fireside ambience even if your home doesn’t have a chimney. All Onyx electric fires are plug and play, requiring nothing more than a connection to the mains electric to get up and running. Meanwhile, Liv3 gas stoves are compatible with a balanced flue system, making installation flexible and convenient.

Easy Installation

Electric fires such as those in the Avanti and Fusion ranges come with everything you need to install them as a single-sided, two-sided or three-sided fire, allowing for ease of installation. Meanwhile, Avanti Gas fires are designed for ease of installation, with a choice of frames available to make it easier than ever to get the perfect hole-in-the-wall finish.
