Installation of Oxypod to reduce heating costs in social housing (CP770)

LEAD AGENCY: Hafod Housing Association
OTHER PARTNERS:
PROJECT SUMMARY: This project will install a complementary heating system enhancer, Oxypod, in 57 properties in Cardiff. The device removes dissolved gasses from the water in central heating systems, thereby reportedly increasing the efficiency of the boiler, and reducing heating costs.
EVALUATION METHODOLOGY: Interviews will be conducted in a sample of households to capture comfort levels, behaviours and previous energy expenditure. Interviews will be repeated after a winter heating period to establish the impact of the technology.Thermal data-logging will be performed in the living and main bedroom and manual energy meter readings will be recorded by householders. Gas usage will be automatically logged (where possible) in a sample of homes, and residents will be encouraged to record regular meter readings manually. Probe loggers will be used on selected radiators to establish changed heating patterns and thermal levels of the radiators.Thermal imaging of radiators will also be carried out in a small number of homes 1-2 months after installation of the Oxypod, to be compared against a control group which have not had Oxypod fitted, to assess differences in the thermal profile of heating emitters. Monitoring will be for 12 months, and will include a full winter heating period.
PROJECT OUTCOMES: The project will assess the impact on residents’ comfort and heating costs of this relatively simple low cost device, and its appropriateness to addressing fuel poverty.The project would allow Hafod Housing to roll out the installation of Oxypod further to targeted properties in line with their affordable warmth strategy, and inform interested parties of the benefits of this investment. NEA would publish results to inform other housing providers of the expected savings and fuel poverty impact which could be achieved with this device.
