I'm working on connecting a solar hot water before a takagi tankless heater. The solar water heater will get up to 160 degress so between them is a mixed valve set at 120. The tankless is also set at 120.
To fix this problem i'd like to have a way to bypass the preheated water and instead use cold water to go to the tankless. Would a TEE with a electric gate valve with a temperature control connected to Cold do this function? Can a gate valve be controlled by an aquastat??
Does anyone have any advice?
Another obvious solution is to turn off the tankless in the summer months and use the solar exclusively(and vice-verse in the winter) to solve the problem. An automatic way would be better though (and I like challenges).
