Although those Fotek DC-DC SSRs are easy to wire up, unfortunately they have quite a high maximum voltage drop (1.6V, see [www.fotek.com.hk]) and hence there will be a lot of heat to get rid off. You would be better off using 2 mosfets (chosen for very low Rds(on) @ 4.5V gate voltage) wired in parallel.

I still don't get how I would connect these up, or what kind of mosfets to go for.

But that aside, does that mean I could go for a big PCB board (assuming I solve the mounting issue) and just use the two mosfets between the board and the heater?
