My wood boiler and storage system was designed by me over the years. It makes sense to me and in normal operation requires one switch to be operated manually during operation but since I have a wood boiler with storage with oil backup and a SHW system that is on the periphery, its decidedly more complex system than a standard household system. I expect it doesn't help that I have numerous hand valves in the piping that are used for service but don't have to be used for normal operation. The system is set up so that unless hand valves are closed deliberately, it will "fail" in a safe mode and if it isn't fed wood it revert back to the oil boiler with no action required by an operator. When I shut down for the summer, I switch off the power to the wood boiler controls and the system reverts back to an oil system. There is a seasonal switchover on the SHW system that requires two hand valves to be moved which allows house DHW system to run directly off solar.
Even though its simple to me, I don't know if I would trust someone else to operate it without some training. So how about your system?
My theory is someday when I sell the house, I will probably have to close off a few isolation valves and remove the wood boiler as I expect the system would be too complex for most buyers. Even though the operation is fairly simple, the underlying control logic and relays needed to make it simple are not simple. Luckily my storage tank can be broken down fairly painlessly but the wood boiler would be a hassle.
