Zero Emission Boiler
Most people heat their homes with a gas or oil boiler because they are reliable and cheap, but these cause huge amounts of local pollution and carbon emissions – around 20% of all UK carbon emissions come from heating our homes. tepeo is attempting to tackle the UK’s biggest challenge to achieving its Net Zero target: rapid and low cost decarbonisation of domestic heating.
The Zero Emission Boiler (ZEB) is a low carbon, cost-effective “plug ‘n’ play” replacement for a fossil fuel boiler. It matches the high temperature and power performance of conventional fossil fuel boilers, but is powered by electricity. Crucially, it decouples heating demand from electricity consumption with its ultra-high density dry core thermal storage, optimised by cloud-based algorithms and machine learning. THE ZEB’s smart technology charges the core with energy at the cheapest and ‘greenest’ times of the day ready for when it is needed. The ZEB can also charge on excess solar electricity generated by a home’s solar PV that would otherwise have to be exported to the grid for a low price.
Installation causes minimal disruption to people’s homes and the overall proposition is a compelling and affordable alternative to heat pumps or hydrogen boilers. The ZEB will drive rapid decarbonisation of domestic heating through electrification while supporting the higher renewable penetration on the grid through Demand Side Response and flexibility.
Launch edition products are expected to sell for around £5,000, plus an ongoing monthly service/maintenance charge to be determined.
To date ZEBs have been installed in 11 units in domestic trials over the 2020/21 heating season which have been performing very well. These units continue to deliver the full heat demand of the trial homes in place of their previous boiler, reliably providing heat to the central heating system when called for by a thermostat. Charging of the ZEBs has been optimised across a range of different electricity tariffs, including near to real-time electricity pricing. Qualitative feedback from trial customers has been very positive with one customer stating “the ZEB is working well. And this makes me very happy. Peak time heating coming from the battery, no electricity being used!” and another stating “we love our ZEB, thank you”.
