There are a lot of possibilities, so let's start by getting some information. When you say it's always lukewarm, where are you testing? At a faucet or at the water heater drain valve. If you've tested at a faucet, try at the drain valve and see if it's the same. Meantime, we'd like a picture of the manufacturer's label on the side showing the serial number.
