This looks like being the same as the earlier mentioned eBay valve. If you are a bit handy, this should do the trick too

You are right, that is a better value. In my experience, you either want heat, or you don't, so an on / off setting on that valve is all that is needed. The variable setting is not necessary and therefore you don't need the fancy potentiometer offered by the E-bay vendor.
