I have to replace washers for two hot water taps.
The pipes running to the taps don't have valves or gates so cutting
the water supply isn't as simple as I'd hoped.
There are other gate valves dotted around the cylinder but they are
stuck (presumably limescale as hard water area)
Is there another way of isolating individual taps without having to
drain the whole system?
Usually no (because individual shutoffs would have
no other function.) Basic method is:
1. Shut off main water supply.
2. Open the first faucet on which you want to work
and let it run dry before disassembly and repair.
3. Repeat for other faucet.
4. Shut off all faucets, turn on water supply, then
open all faucets one by one (to let any air bubbles
escape from the water column.)

If you have an electric water heater, I would like to suggest that
your first step be to turn it off, and that your last step, after you
bleed the air, would be to turn it on. You don't want to partially
drain the tank (which could happen depending on where it is located)
with the power on - it burns out the heating element

Given your situation, I would do some wholesale valve replacement in
the system. In fact, it would be desireable to replace every old
fashioned gate valve with modern quarter turn valves, and even add
some new shutoffs for future service work. The payoff will be the huge
time saving the next time some maintainance is needed. HTH
