Hello fellow DIYers.
In my house I have an unvented hot water cylinder with a thermostatic pouch 1/3 of the way up. In the pouch there is a probe attached to a thermostat that controls a valve on the primary circuit, whose dry contact is connected to the call for heat from my boiler. So far so good.
What I don't like about this setup is that it is a bit dumb. For starters, the thermostat is a cheapo piece of plastic and very imprecise in its measurements. Secondly, I have no visibility over the internal temperature of the cylinder.
Is there any way to make this smarter?
I was thinking I could potentially replace this dumb plastic thermostat with a ds18b20 temperature probe, and use that as a temperature input to a smart device that controls the valve. Would something like that work? Is there a product that has the appropriate 1/2" thread to screw onto the pouch?
Any other ideas to improve on this?
