Hot water is a must-have everywhere, from the industrial sectors to our bathrooms and kitchens. Today there are several solutions that are suitable both for businesses and for domestic use. The right choice between different types of water heaters influences convenience and, for sure, energy costs.
Types of Water Heaters
Conventional Storage Tank Water Heaters

The most common option among types of hot water heaters is storage tank water heaters. They have a special tank where hot water is constantly kept. They are suitable for large families and are also considered one of the types of residential water heaters.
Pros | Cons |
Affordable initial cost | Higher bills |
Simple installation | Plenty of space required |
Reliable hot water supply | Limited hot water capacity |
Wide availability | Not a long lifespan |
Tankless (On-Demand) Water Heaters

Tankless or flow-through models heat water only when you open the faucet. This definitely saves space and energy.
Pros | Cons |
Energy-efficient | Higher upfront cost |
Compact design | Limited flow rate with multiple users |
Long lifespan | Requires professional installation |
Endless hot water supply | May need upgrades to electrical/gas systems |
Heat Pump (Hybrid) Water Heaters

Unlike other water heater types, hybrid heaters use heat from the air or ground to heat water. This makes them energy efficient, especially in warm regions like California.
Pros | Cons |
Extremely energy-efficient | High initial cost |
Lower long-term operating costs | Requires more space |
Environmentally friendly | Works best in mild climates |
Long lifespan | Slower water heating time |
Solar Water Heaters

The sun powers solar models, which is why they are perfect for regions with many sunny days. So, if you live in the endless summer, you can skip other types of water heaters while choosing your one and only and buy a solar water heater.
Pros | Cons |
Free renewable energy | High upfront investment |
Eco-friendly | Weather-dependent efficiency |
Low utility bills | Requires backup system |
Long-term savings | Complex installation |
Condensing Water Heaters

Condensing heaters run on gas. They use the heat from the flue gases to operate. Useful for homes where you need a large volume of hot water.
Pros | Cons |
High efficiency | Limited to gas-powered homes |
Lower energy costs | More expensive installation |
Suitable for large families | Requires proper venting |
Long-term durability | Not ideal for small households |

How Much Do Different Types of Water Heaters Cost?
Prices vary greatly depending, of course, on the water heater types.
Storage models are mostly inexpensive. Most of them are more than affordable, but some can reach the middle price category. Flow-through devices are more expensive, but they save energy. Solar and hybrid heaters are the most expensive, but they pay for themselves over time.
How to Keep Your Water Heater Running Efficiently
