I am upgrading the central heating and hot water control system in our large detached Victorian house and needed to build a customised system with two zones and an immersion heater. I use the Heatmiser 4 channel timer, a Heatmiser wall thermostat and a solid state relay for the immersion heater interface, and with a little creative wiring design and relabeling, was able to use this Heatmiser connection unit to achieve exactly what I needed it to do. It is well made, excellent value and very versatile, not just limited to the underfloor heating systems that its name implies! It is larger than I expected, which is great as there is plenty of room for wiring - highly recommended!
