Solar thermal connection to Burnham V73
Want to optimize solar thermal hot water with Burham oil-fired boiler; thoughts on where to connect; from thermal storage to boiler; from thermal collector to boiler to thermal storage... I would like to use the boiler as backup for hydronic heating; using the solar hot water first domestic hot water and second for heating. I'm thinking that if I could keep the water temperature in the hydronic system constant at say 100-120 F ambient would stay constant, boiler would be used less. Any and all thoughts welcome please...
