Hybrid Heating Trials

Phoenix has invested in several Hybrid Heating Trials in 2024 with our partners Refresh NI, Alpha Housing and Radius Housing. Hybrid heating systems offer several benefits: No Expensive Upgrades needed. Unlike an Air Source Heat Pump, a hybrid system does not require expensive and sometimes infeasible home upgrades such as extra insulation and mechanical ventilation. A hybrid system is 100% compatible with existing plumbing, requiring no upgrades there either, working with the existing plumbing and radiators within the home. Carbon Savings. The hybrid heat pump significantly reduces a home’s carbon emissions, releasing 60% less carbon than an Oil System and 49% less carbon emissions than a gas only system. Space Saving. As the combi boiler provides hot water there is no need for a hot water tank, saving space within the home. Security and Choice. A hybrid system has the ability to adjust based on gas and electricity tariffs, allowing it to run in the most cost effective setup.

With Refresh NI, Phoenix have been conducting a hybrid heating trial in South Belfast throughout 2024. The trial features a Mid-Terraced house with a relatively low EPC rating of C71. The home has two occupants and in December 2023 took delivery of a new hybrid heating system developed by Alpha, comprising a 4kW Heat Pump combined with a 33kW Combi Boiler. Throughout the trial period, the total cost for heating (not including domestic hot water) was £936.83, averaging £2.56 per day. If the same heat was provided by an air source heat pump with an efficiency of 280%, the annual fuel cost would have totalled £1,120.18 or £3.06 per day.
