• Runs on electricity, No gas connection required.
• Storage capacity, Uses a tank to store hot water.
• Thermal insulation, Keeps water hot, but once emptied, reheating takes time.
• Easy installation, No need for a gas connection.

--------------------------------------------------------------------

✅ Easy installation. Suitable for any home with an electrical connection.

✅ Perfect for gas-free areas. No emissions or special ventilation needed.

✅ Lower maintenance. Requires less upkeep than gas water heaters and boilers.

❌ Limited hot water supply. Once the tank is empty, reheating takes time.

❌ Higher electricity consumption. Compared to gas water heaters.

❌ Space requirement. Needs adequate space for the storage tank.

• Works with gas (natural, butane, or propane).
• No storage: heats water instantly when needed.
• There are atmospheric and sealed models (sealed models are safer and more recommended).
• Requires gas installation and smoke outlet.

---------------------------------------------------------------------

✅ Unlimited hot water, as it heats instantly and doesn’t rely on a tank.

✅ More efficient than an electric water heater, as it only consumes energy when in use.

✅ Lower operating cost if gas is cheaper than electricity.

❌ Requires gas installation and, in some cases, a smoke outlet.

❌ Temperature fluctuations may occur if multiple taps are used simultaneously.

❌ Maintenance required: Burners can accumulate limescale over time.

• Dual function: domestic hot water and heating.
• Available in condensing, gas, oil, and biomass models.
• Condensing boilers are the most efficient and recommended today.
• Higher initial investment but greater long-term efficiency.

---------------------------------------------------------------------

✅ Ideal for homes with radiator heating.

✅ Higher energy efficiency with condensing models.

✅ Long-term savings on energy consumption.

✅ Can be combined with renewable energy sources (solar thermal).

❌ More expensive than a water heater or gas heater.

❌ More complex installation, requiring gas connection and smoke outlet.

❌ Requires maintenance to ensure efficiency.
