  • Sizing a Gas-Fired Combi Boiler - GreenBuildingAdvisor

    Feb 25, 2019 · Combi boilers basically suck even for regular code-min type houses. They're a better match for homes with big heat loads and small to moderate hot water needs. They suck even worse for highly efficient houses. That said, with high mass radiators such as concrete slabs they can be made to work without short-cycling.Get Price
