...We have just the basic water set up with two faucets (one with a hand pump for the small tank and one that you turn off and on when you are hooked up to outside water). If we installed one of the InSinkErator-type on-demand hot water taps, do we also need to have a water pump?

I think it depends on when you want hot water.
- If you want the hot water to be available only when you are hooked up to outside water, then you can install it as usual, tapping into the line to that faucet.
- If you want water when using the tank, then the hand pump won't work because it is built right into the faucet and has no way to pump water through the heater; so, you need to add a pump. Since the heater is electric (I assume), you will only be using it when you have outside power, so an electric pump shouldn't be a problem.
A relevant recent topic is
[b]Water pump install, Can I pick your brains?.
Here's a possible arrangement - I haven't built this (my
Boler has a built-in pump and regular water heater), but I would consider this arrangement if adding on to the basic setup...
The hot water would only be available while using the tank if the pump was also added.
That's quite the forest of spouts, but there was some support in that other topic for not going to a single-spout faucet, and I suppose that would especially apply if using a hot water dispenser that normally has it's own spout.
