I am planning a cabin. I would like a combo boiler to supply minimal radiant heating while the cabin is not occupied. While the cabin is occupied, we will use wood boiler. But we need domestic hot water for 4-5 people with two bathrooms. Propane will be the boiler fuel. What do you recommend?

I'm missing something, which is often the case. If your hot water needs are when the cabin is in use, why not use the wood boiler to heat your domestic needs?
