luke warm water??!
First check the water in the tank itself by bleeding some off from the overflow valve. Is that hot or not?
If so, you likely have cold mixing with your hot water. This is usually due to winterization valves not being in the correct orientation OR a shower head with the water shutoff at it but water at the faucet on.
