I dont think it would be an issue. If you do have 60 PSI water pressure in your house, well, thats only when the lines are sitting waiting to be opened, not whats coming out of the faucet. After all pressure buildup is caused by resistance. So unless you deadhead the hose running into the heater core, it should never see much pressure at all. Just lots of water movement.
