Wet heating system deaerator

Problem Addressed
The English Housing Survey Energy Report states that 89% of homes use a boiler + radiator heating system, most of which use gas or oil as their power source. In these types of wet heating systems, the circulation of water is typically the least efficient aspect of their operation. The buildup of magnetite deposits in boilers and radiators caused by trapped air can dramatically affect heat transfer, particularly in older systems. UKGBC’s Whole Life Carbon Roadmap supports the phase-out of all gas boilers, and an end to sales of gas boilers by 2030 but improving the energy efficiency and reducing the carbon emissions associated with the existing stock of boilers must be addressed during this phase-out.
Case Study
Tadpole was tested on four sites between 2011 and 2012 at Interserve’s energy services division over the course of an 8-week period – 4 weeks without and 4 weeks with Tadpole installed. Savings per site ranged from 8% to 30% with an average across all four sites of 19% with a typical payback within 24 months. After the testing, Tadpole was rolled out to 110 sites nationwide with an average ROI of 18 months.
