We recently purchased a vacation home that has an oil fired boiler with adjacent non-powered water storage tank that has an immersion thermostat on it to control calling the boiler for heat. I’m trying to determine what I could do to set things up so that I can leave the water at 60 degrees F (15C) when we are not at the vacation home and bring up to 125F when we are there.
The current thermostat is a TPI immersion thermostat which does not support any sort of automation. There are 6 wires coming into it. 2 for calling for heat from the boiler, 2 for 24VDC and ground, and 2 for the temperature probe. I’ve googled for hours trying to figure out what options I have and finding it very confusing what I can and cannot do. I’m located in the US. I see lots of thermostats, which seem not related to water/immersion. I found something called the Tesla T-Smart, but that seems to be in the UK only. I’ve seen that some regular thermostats also have support for hot water, but I can’t tell if that’s a solution.
Any stories or suggestions would be most appreciated.
