Voltalis and Passiv Partner to Pair 10,000 New Heat Pumps with Demand Response Tech
Passiv brings heat pump flexibility across the UK with Voltalis
  • European leader in demand response and leading UK provider of smart thermostats for heat pumps announce deployment of 10,000 new heat pumps integrated with demand response technology by the end of 2025.
  • Active users set to benefit from enhanced heat pump performance, environmental sustainability and improved cost savings.

Voltalis, the European leader in demand response services, and Passiv, a leading UK provider of smart thermostats for heat pumps, have announced a strategic collaboration to accelerate energy savings, renewables effectiveness, and home decarbonisation for heat pump users across the UK.

Under this partnership, Voltalis will integrate its advanced demand response technology with the Passiv Smart Thermostat, adding a flexibility layer that optimises consumers’ heat pump energy use. This collaboration enhances the efficiency of their heat pumps, unlocking greater environmental benefits and energy cost savings.

Demand response technology, also referred to as ‘intelligent demand-side management’, temporarily modulates electricity consumption in homes and buildings to balance supply and demand, ensuring the power grid’s stability.

Another effect of Voltalis’ technology being paired with Passiv’s product is that the heat pumps will be tapped into a demand response system, helping mitigate the intermittency of renewable energy sources. Rolling out this joint solution into UK homes won’t impact Passiv’s existing heat pump deployment process and has no additional installation cost to the consumer.

Most crucially, this solution offers substantial savings for households facing rising energy costs. Voltalis’ technology reduces energy consumption by on average up to 15%, while the Passiv Smart Thermostat enhances heat pump efficiency by 30% through smart tariffs and efficiency improvements. Through the integration of these two technologies, the potential for even higher savings for consumers is achievable – all without affecting users’ comfort levels or routine.

The strategic partnership marks the latest step in Voltalis’ broader plan to develop up to 5 GWp of demand response capacity in the UK market by 2030, representing a £1 billion investment. Voltalis’ technology is already deployed across Europe, connecting more than 1,500,000 appliances across 250,000 buildings in eight countries.
