For the contractors that use a indirect water heater with a condensing gas boiler (instead of installing a combi boiler) if there was a indirect water heater that doubled as a buffer tank would you use this type of tank?
One tank dose the primary secondary piping, adds water volume so the boiler will not short cycle when small zones are calling for heat and the same tank provides domestic hot water for showers and other use of hot water in the house.
Would you use a tank like this?
