What is the best water heater to buy?

An electric heat pump.

I removed my instant natural gas heater and replaced it with an electric heat pump. The heat pump is extremely efficient, even in cold climates. Natural gas is a fossil fuel and contributes to global warming. Electricity is gradually being more produced from renewable sources, which are the only way of the future.
