The combined space and water heating systems (combi) uses a high efficiency direct vent burner that eliminates safety issues associated with natural draft appliances. Past research with these systems shows that utilizing condensing water heaters or boilers with hydronic air handlers can provide both space and water heating with efficiencies of 90% or greater. Improved controls have the potential to reduce some of this complexity and boost the measured performance.
