Our Challenge

The UK has legislated to become “net zero” by 2050 which means a radical re-think about the way we heat our homes.

Revised Building Regulations Part L for new build from June 2022 and further updates planned in 2025, will only address a small part of the housing challenge.

Integrating the necessary low carbon heating, hot water and ventilation systems is a challenge. To achieve Net Zero, these measures must also be combined with significant insulation upgrades, installation of PV systems and provision of EV charging.

Monodraught have developed HomeZero to assist Developers, Housing Providers and Contractors to reach Net Zero requirements. HomeZERO provides a simple, single solution that can be quickly and easily fitted with minimal impact on the indoor amenity space of the home, and that brings all controls together, in a factory assembled energy module.

Innovation at a glance

HomeZERO is an innovative, robust, custom designed outdoor energy services module for new build and retrofit Net Zero Energy (NZE) homes. It is a single, off-site manufactured energy module which integrates Air Source Heat Pump (ASHP), Mechanical Ventilation with Heat Recovery (MVHR) and Sunamp Phase Change Material (PCM) hot water heat battery store.

All associated ducting, pipework, pumps, valves, filters and drains are pre-fitted and factory tested to minimise time and disruption on site. Temperature and air quality monitoring, heat meters, flow sensors and energy meters are all included built-in. The controls system is fully integrated and remote monitoring with 4G/5G connectivity reduces call outs.
