The Zero Emission Boiler

The ZEB is an award-winning, low carbon, plug-and-play replacement for a fossil fuel boiler. It heats your home affordably while lowering your carbon footprint and supporting renewable generation.

The ZEB is powered by electricity and works like a thermal battery to store heat really efficiently until it is needed. Our patented heat-management technology then cleverly releases the heat to your radiators, underfloor heating and water tank when your thermostat calls for it.

The ZEB’s intelligent charging algorithm looks at your tariff, the weather, the grid carbon intensity and how much heat your home uses to automatically charge up – keeping running costs & carbon low, while avoiding wasted heat.

Inside a ZEB's brain

The ZEB automatically and dynamically charges. It does not simply charge up off-peak, but intelligently based on the factors below. This minimises running cost, while also providing heating when needed. The ZEB calculates:

  1. How much heating the home needs – based on historical heat demand & live weather forecasts
  2. Given the heat demand, it determines when to charge – using the customer’s tariff price & timing to find a cost-optimal charging schedule
  3. Electricity carbon intensity is then added to the mix, so that if the ZEB only needs a limited charge, it will preferentially seek that charge at the lowest carbon times of day & in-line with the tariff pricing

This model is completely flexible across a range of tariffs: from Economy 7 or fixed-time EV tariffs, to flexible / variable time-of-use tariffs where pricing follows the wholesale market.

The ZEB can also factor on-site generation like solar into its charging calculation. This feature is in BETA now, but due for release in Spring 2023.

Technology comparisons

Heat pumps benefit from a CoP but have a limited ability to take advantage of variably priced electricity.

Current EV tariffs have a ratio of 4:1 between peak and off-peak pricing, enabling a ZEB to compete on running costs against a heat pump.

ZEBs provide the lowest total-cost-of ownership today

With 0% VAT and access to the Boiler Upgrade Scheme, this would drop significantly & the upfront cost of a ZEB would be less than a fossil fuel boiler
